[inland oak]

linux is one pure IDE for web dev

[unborn zealot]

are you only using nginx for mysql?

[native tide]

postgresql

[unborn zealot]

why not install postgresql via the installers on the website and use the Psycopg2 python package to use it in flask

you could use the first part of this tutorial to install it https://realpython.com/flask-by-example-part-2-postgres-sqlalchemy-and-alembic/

use this only for development tho

linux will always be better for deployment for security risks and stability

[inland oak]

don't ask to ask

just ask

[thorn igloo]

save the files on your server system and just add the file path to the database

what do you mean?

create a directory and save the files to that directory. then create a route to serve the files from that directory, you can specify this, lets say this path is /files, you'd define it so that it accepts dynamic values: /files/<file_name> etc. then when you save on your db, you'd save as something like filepath = "/files/file_name"

[mystic wyvern]

Hello there , simple question what is the point of cookies in website?

[thorn igloo]

i wrote this to serve images

[dense slate]

Any recommendations on how to implement real-time chat into my web app?

React+Django+GraphQL stack

[mystic wyvern]

i think you should use something like ajax(maybe)

[thorn igloo]

in simple terms, to remember stuff

[mystic wyvern]

oh! so i must use it in my website yeh ?

[thorn igloo]

depends

on what you want to do

[mystic wyvern]

ok you mean in "remember stuff" like username or password or can save any thing else ?

[thorn igloo]

yeah, you don't want to save sensitive data like that in a cookie

like, you can use them to remember items someone saved in a cart or just basic info. I think they are mostly used for session management etc (when you want to authenticate a user etc)

what i am saying is not the full story, so it's best you do your research

in addition to cookies, there's also JWTs, and localstorage i believe

[mystic wyvern]

thanks a lot ❤

[inland oak]

I heard term web-sockets/channels about it (never tried)

oh, remembered another word = it requires async perhaps

anyway, web-sockets should support real time thing to make

in theory

[dense slate]

Hmm, yea that's a whole mess if I get into that. Maybe just an email-like messaging for now would work.

[dense slate]

Is there a way to push notifications/messages to a client without websockets when they happen?

Channels doesn't seem to have taken off too well so I'm not so sure about using them.

[inland oak]

the most simplistic solution should be just... making in timer requests to API end point in order to find new messages.

[dense slate]

So just polling every X seconds if they sit on the chat page.

[inland oak]

not really optimized solution, but hay, still a solution.

yeah

just make some way to pause/quit chat page if they aren't active

[warped heart]

what does sphinx class as a homepage url pattern?

[proper hinge]

Why don't I get CSP violations when I run my Flask site locally? It's annoying to have to redeploy every time to see if I fixed my policy.

[opaque rivet]

Locally, your server and your request may be on the same origin

[proper hinge]

But it's requesting resources from other domains

[ember eagle]

Lol! Sounds like you made it through

[lean mountain]

I send myself a zip file of a website(blog site) to myself but for sum reason I can't seem to run it

[ionic raft]

I've hit a bit of a wall with a Django error. Question on Stack Overflow here: https://stackoverflow.com/questions/68306715/in-django-3-2-i-am-getting-this-error-app-importerror-module-apps-articles-d

[dapper solar]

@app.route("/admin", methods = ["POST", "GET"])

            for i in usr:
                form.username.data = i.username
                form.theClass.data = i.theClass

        return render_template("admin.html", result = usr, form = form)```

i am trying to update the values but it doesnt work.

i get a big csrf token at get request. can anyone help

?

[ionic raft]

Just in case question: Does your template have the csrf token tag?

[dapper solar]

yeah i added it on the html side

i dont get whats wrong TT

[warped heart]

so with sphinx,

<nav class="bd-links" id="bd-docs-nav" aria-label="{{ _('Main navigation') }}">
  <div class="bd-toc-item active">
    {{ generate_nav_html("sidebar",
                         maxdepth=theme_navigation_depth|int,
                         collapse=theme_collapse_navigation|tobool,
                         includehidden=True,
                         titles_only=True) }}
  </div>
</nav>

This will generate a toctree on said page, but how can i choose what to add to it?

[warped heart]

nvm my bad

i just modified some thing slightly

[crimson crypt]

basically i want to make this model so one owner can have multiple structures and a structure refers only to one owner. The problem is that the foreign key of the structure is not getting the id of the owner which is wrong, because it should refers to it

from django.contrib.auth.models import AbstractUser
from django.db import models


class CustomUser(AbstractUser):
    is_customer = models.BooleanField(default=False)
    is_owner = models.BooleanField(default=False)


class Customer(models.Model):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, primary_key=True)
    short_bio = models.CharField(max_length=255)


class Structure(models.Model):
    structure_name = models.CharField(max_length=255)
    avaiable_rooms = models.IntegerField()
    price = models.FloatField()
    owner = models.ForeignKey(CustomUser, on_delete=models.CASCADE)

[gritty cloud]

Captcha is built to stop scrapers like yourself

@gusty heart

[gusty heart]

I undertand but I not have bad intentions, just, that site is a little intesable and the get new products I need chek manually every time, then I just want, when the site is accesible, check automatically for new items... and get some notification... just that...

[gusty heart]

and I dont want break the captcha, I want solve it manually with my real user... normally like a browser

[rustic sky]

late reply, sorry. And ehh, I'll just use a model. I don't think I'll have other admins to my site but meh

now I just need to figure out how to structure it

for only one text field entry

okay, maybe not actually

might need a color option to it

[gritty cloud]

i understand, but sites with captchas are pretty hard to get around. the latest captcha doesn't return an error you can catch, and locks all other parts of the site

if you really need this data, then the site should have a REST API for passing data between front and backend

or maybe one that is meant for public consumption

[opaque rivet]

If you want to manually do the captcha, you can use selenium as it'll open a browser instance which you can interact with. (plus it can automatically scrape the data once you've verified the captcha). apart from that, there's some captcha services out there but they're paid. cheap though.

Hello need help returning a variable:

this is my code:

def login():

 takeName = "somethingsomething"
    if takeName == "somethingsomething":
       return redirect(url_for('menu', takeName)) #want to return takeName to use inside of menu() function

@app.route("/menu", methods=['GET', 'POST'])

hi, i'm attempting to deploy my flask app to linode. it works locally, but when i deploy to linode and try to access the webapp, my apache logs show: https://paste.pythondiscord.com/pokevedoxe.yaml

here is my webapp.wsgi:

logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/webApp/")

from zealbot.main import app as application
application.secret_key = 'asdfjkl;'

and here is my main.py: https://paste.pythondiscord.com/cukomewuhe.py

and here is my folder structure on the linode server. anyone available to help? i'm not sure why it's not recognizing the module - it's clearly there

[heady ermine]

hy, was stuck in a simple django issue, wondering if anyone here can help

[inland oak]

hmm, bot for some reason prevents me to share the link.

[hollow ingot]

You need to pass it to pass "takeName" as a path parameter, all you need do to is the below.

@app.route("/login", methods=['GET', 'POST'])
def login():

 takeName = "somethingsomething"
    if takeName == "somethingsomething":
       return redirect(url_for('menu', takeName=takeName)) #want to return takeName to use inside of menu() function

@app.route("/menu/<takeName>", methods=['GET', 'POST'])
def menu(takeName):
 
 print(menu(takeName))

[normal pebble]

@inland oak we filter that link because people tend to drop it without explanation to people looking for help, which we consider somewhat rude

[inland oak]

so, if I 'll give description, it would be ok?

[normal pebble]

i mean it'll still get filtered

but in general the content of the webpage is good, it's just the way the link is used that can be unhelpful

[inland oak]

dontasktoask dot com
this link could be provided as a new rule: don't ask to ask, just ask

perfectly explaining why they are asking their questions in a wrong way

[normal pebble]

it's covered in #❓｜how-to-get-help

it will work too 😉

@summer cairn Hey, modularize your zealbot folder by adding a __init__.py file into it, and you should be okay.

[willow glen]

fixed it

[native tide]

im starting out on html lol

need help

whats the size for an custom bullet in an ul

[rustic sky]

Do I create another app in my project for other features of my site that I'd like to have? I don't have a models.py

[quaint dew]

hello
i was just reading a simple tutorial for flask
and there was this function-:

def gfg():
   return 'geeksforgeeks'
app.add_url_rule('/', 'g2g', gfg)

i dont understand what the second argument(endpoint) in this does, as its not explained and changing it doesnt effect the webpage either
app is just a flask.Flask object btw

[hollow ingot]

It map's the name "g2g" with the path "/"

by default, if you don't provide the second parameter, it takes the name of the view function, which is "gfg" and maps it to "/"

you can ignore the second parameter for now, if your early on your web dev journey

and @quaint dew ,

@app.route("/")
def gfg():
  return "geeksforgeeks"

is far more easier

[quaint dew]

yeah

also thank you for the explanation

[hollow ingot]

Np.

[shy vessel]

Guys, I am a front-end dev and recently my boss told me to build a django project

Any learning advices?

I used to use cpp in school and I have learned how to use python

but never done things related to backend

[native tide]

u may visit some youtube tutorials and familiarize urself about django

if want i can also help you

feel free to DM me for any help

[rigid folio]

Hi, this is django/python question.. Can I ask:

1. Why we need to add *args, kwargs everytime we init? where will this args and kwargs be passing from?
2. Why we need to super(<the same form>...) when we init?

class BillForm(forms.Form):
    pass

    def __init__(self, *args, **kwargs):
        super(BillForm, self).__init__(*args, **kwargs)

[inland oak]

in general we dont' need both.

but I can see you are inhering from Form.
If you are going to add your own code in init, you need doing those actions in order to not override already existing init.
I can guess that if you aren't needing any logic in init, just don't define init at all. It would be inheritered from Form already.

basically, do this init/super/args/kwargs only if you are going to add some code logic besides this one line, otherwise don't re-define init at all

(never touched those forms, but this is a logical python... logic I can guess)

[rigid folio]

okayy, meaning if i add something to the init part and NOT call for super, the form wont show the other stuffs except the newly added part?

[inland oak]

if you will redefine init and not call super, it will just get broken highly possibly

it depends on what it has in its internal code

follow inside the library and read

what happens in its init

[rigid folio]

right, okay thanks a lot @inland oak !!

[summer cairn]

hi, thanks for following up. i actually have __ init __.py within the next level down in the structure. here's my init file contents: https://paste.pythondiscord.com/qasilejeqa.py -- should i just change the name of my main.py to init and init to main?

[summer cairn]

here is my init in my current folder structure

[willow glen]

using python, how do i prevent people from going to specific urls before logging in?

[paper pier]

am using builtin authentication form

class login_form(AuthenticationForm):
    pass

views.py

def login_view(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username = username, password = password)
        if user:
            login(request,user)
    form = login_form()
    return render(request,'mainapp/login.html',{'form':form})```
is this a right way to login?

[paper pier]

i didnt worked with authentication before but its something like this https://docs.djangoproject.com/en/3.2/topics/auth/default/#the-permission-required-decorator

[willow glen]

im using flask

[paper pier]

sorry then idk anything about flask

[thorn igloo]

you could make a decorator to check whether someone is authenticated. if they are not you can redirect them elsewhere

[quasi relic]

hey, anyone know how to config flask-session with sqlalchemy, I cannot find any solution and the docs are not the best and no real examples

[summer cairn]

https://www.youtube.com/watch?v=dam0GPOAvVI << step by step youtube on how to do this

[hollow apex]

Heyo so

is it possible to run raw sql code in this django-python shell?

in this case ```SELECT * FROM User

[quasi relic]

thank you so much !

[hollow apex]

cuz this django queries are rather inconvenient

[quasi relic]

anyway there is no Flask-Session package used

I have not got problem with the database itself and the models or other stuff only this and the config of it

[summer cairn]

ah i see, my bad

[jovial cloud]

For flask, you can use an extension called Flask-Login for such authentication issues and others. Go check out the docs for info on how to use it- https://flask-login.readthedocs.io/en/latest/
Alternatively, you can use Miguel grinberg's flask mega-tutorial Chapter 5 to learn how to use Flask-Login

[sonic island]

use loginrequired mixin...

Hello Everyone!!

I'm developing an Automated Time Tabling System application with Django
After randomizing the courses provided by the schools admin on the table, how do I work with constraints (like carryover courses) for the courses on the table to prevent clashing?

[desert estuary]

hey uhh anyone here familiar with flask and sqlalchemy
anyway

@app.route('/user',methods=["GET","POST"])
def user():
   def get_data():
      formi=Userform()
      if formi.is_submitted():
         student=Students(fullname=formi.fullname,personal_email=formi.personal_email,dialling_num=formi.dialling_num,branch=formi.branch,ocupation=formi.occupation)
         db.session.add(student)
         db.session.commit()
      return render_template("User/edit_page.html",form=formi)
   x=Students.query.filter_by(fullname=???)
   return render_template("User/Homepage.html")

im strugglin on the place where i put ???
i want to assign it to the logged in user so it can display his own info to him

im having a hard time understanding sessions

[jovial cloud]

What is '???'

[jovial cloud]

You have to pass the object for the logged in user to the render_template so you can use it in the template

[desert estuary]

that loggin thing that im struggling with
meanwhile i went to work on something else and

@app.route('/user',methods=["GET","POST"])
def user():
   return render_template("User/Homepage.html")
def get_data():
   formi=Userform()
   if formi.is_submitted():
      student=Students(fullname=formi.fullname,personal_email=formi.personal_email,dialling_num=formi.dialling_num,branch=formi.branch,ocupation=formi.occupation)
      db.session.add(student)
      db.session.commit()
   return render_template("User/edit_page.html",form=formi)
``` i made to view functions that share the same route 
```html
{% extends "Layout_user.html" %}
{% block content %}
<section class="content">
   <h2 id="welcome">Welcome to your Dashboard</h2>
   <div class="info">
      <div class="userinfo">
         <img src="{{ url_for('static',filename='img/imageblank.png') }}" alt="profilepic">
         <a href="{{ url_for('get_data')}}"></a>
      </div>
   </div>
</section>
{% endblock %}

and gaved the <a> the get_data function so when i click it triggeres that function
and im getting this error

werkzeug.routing.BuildError
werkzeug.routing.BuildError: Could not build url for endpoint 'get_data'. Did you mean 'static' instead?

Hey guys,

I have a VPS (on OVH) that has a file based database in it (sqlite).
And I want to make an API to query a specific resource from the db.
The API will be used by a shopify app.

I have so far developed the API using Quart with python.

My question is:
How can I expose the API to the public and secure it ?

[gritty cloud]

Use api keys

Store all api keys as a table in ur db

Each key can have permissions for each user

Then check for an api key in the header of a request

And bing bang bong you got an auth system

[native tide]

Django question: I have 2 model classes inside of an app models.py. In my admin panel I would like to take a model from one of the class and two from the other and display them and allow filtering. I am not sure how to combine them together to allow this.

do u mean display two different model classes together in same page?

How can i convert a flask website to be hosted globally

So anyone can connect to it

[quaint dew]

for eg if this is my code:

from flask import Flask
import socket

app = Flask(__name__)

@app.route('/')
def test_site():
    return 'This is a test website.'

if __name__ == '__main__':
    ip = socket.gethostbyname(socket.gethostname())
    app.run(host=ip) #host_type='global'?

then how do i convert it to be hosted globally

putting in my public IPaddress doesn't work

anyone knows?

[raw compass]

Unless its changed in last few years the built in wsgi server is only suitable for debugging only. Ignoring this you can host it on all interfaces and not just the loop back address you should be able to bind it to all interfaces by using 0.0.0.0

[quaint dew]

putting the ip as '0.0.0.0' starts hosting the server on my private ip

which makes it a localhost

[raw compass]

i'm testing your code now

Changing the last line

app.run(host="0.0.0.0")

$ python flask_example.py 
127.0.1.1
 * Serving Flask app 'flask_example' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on all addresses.
   WARNING: This is a development server. Do not use it in a production deployment.
 * Running on http://192.168.1.37:5000/ (Press CTRL+C to quit)
192.168.1.39 - - [10/Jul/2021 16:48:19] "GET / HTTP/1.1" 200 -

And .39 is the IP from from phone.

So it worked as I would expect.

[quaint dew]

you are able to connect from a different network?

[raw compass]

No as its a private IP address range behind a NAT. You might be able to do port forwarding from your router to make it public. Though its not wise with debug mode.

[quaint dew]

i see

i'll look into that

[native tide]

What about exposing? That's my biggest problem now

[cold estuary]

normally this is how i did directly getting from APi response ```js

function createCharts(data) {

let dailyTemps = data.openweathermap.daily.map((e) => e.temp);
new ApexCharts(document.querySelector("#chart"), {
series: [
{
name: "High",
data: dailyTemps.map((e) => e.max)
},

     ],
     chart: {
             height: 386,
             width: "100%",
             type: "bar",

             toolbar: {
                     show: true
             }

     },
     colors: ["#008ffb", "#00e396"],
     dataLabels: {
             enabled: false
     },
     stroke: {
             curve: "smooth"
     },
   
     markers: {
             size: 1
     },
     xaxis: {
             categories: openweather_day,
             title: {
                     text: "Temperature",
                     
             }
     },
     yaxis: {
             labels: {
                     formatter: function (value) {
                             return value;
                     }
             },
     },
     legend: {
             position: "bottom",
             horizontalAlign: "right",
             floating: true,
             offsetY: 5,
             offsetX: -5
     }

}).render();
}``` what should be changed here if we want to get data from data.json file instead pf direcly from api because i stored my api response nycreating a data.json file

[jovial cloud]

You should not be making 2 view functions with the same route. In this case, all the code can be put in only one function. Put the last template (homepage) below all the other code but outside the if statement

[hollow ingot]

hey !, Just add a "__init__.py" file in zealbot folder, or yeah, you can just rename main.py to "__init__.py" @summer cairn

Hey guys,

Suppose I have a very minimalist API on my local machine.
How do I expose it to the world ?

[thorn pollen]

Hi, How do i use flask-sqlalchemy queries with a Huey worker of a Flask App ?

from engine.models import Languages
from app.extensions import db
from app import create_huey_app
from app.queue import create_huey

huey = create_huey()

@huey.task()
def perform_analysis(text:str):
    app = create_huey_app()
    with app.app_context():
        db.create_all()
        print(db.session)
        print(db.session.query(Languages)) #OUTPUT : None
        print(Languages.query.all()) #OUTPUT : None
        print(db.session.query(Languages).all()) #OUTPUT : None

Output
<sqlalchemy.orm.scoping.scoped_session object at 0x000001FABDA30748>

Same goes with

db.session.add(new_entry)
db.session.commit()

I checked and these queries do work when I am using them directly from a view/route function like this

@blueprint.route('/')
def route_default():
    db.create_all()
    print(db.session)     #<sqlalchemy.orm.scoping.scoped_session object at 0x000001FABDA30748>
    print(db.session.query(Languages))  #[Java,CSS,Python]
    perform_analysis('test')    #No query response using this
    
    return "Success"

What is expected ?
database queries to return results

[desert estuary]

class Admin(db.Model):
   id=db.Column(db.Integer(),primary_key=True)
   fullname=db.Column(db.String(50),unique=True,nullable=False)

[hollow ingot]

@native tide You could host it on a hosting platform, i use Heroku to host all my flask web apps.

[native tide]

I can't, and here's why.

I have a db that's already in a remote desktop.

I made the api so that external apps can use it to access a resource in that db ( which is file based)

And I don't want to migrate the DB unless I REALLY have to

[hollow ingot]

Oh, Okay.

[native tide]

So is there another way ?

[hollow ingot]

There are, but i don't know them well enough. : (

[native tide]

Shoot and I'll try to do some research

[desert estuary]

i was reading the documentation and i wanna know if it's possible to load the user based on other stuff ( email or something ...)

[sullen badger]

Can I learn Python, html, css and js at the same time? I want to be a full stack dev

[desert estuary]

well noo even if you can you'll just burnout unless if you can clone yourself 5 times then yeah sure

[sullen badger]

Thanks for the information sir ,but how can someone be a full stack. I know it's hard😂

[desert estuary]

well firstly to kinda get you feet wet i recommend you to start with some html css and js
js is vast and please please go with the basics don't jump on a framework or something learn to do plain js until u feel u get a grasp of what you're doing then learn some python php node.js idk you pick which syntax and pl you wanna deal with and yeah
also learn some networking stuff how http works ip tcp and other stuff

[sullen badger]

Thank you so much for the tips! Much appreciated bro❤️

[inland oak]

sure, why not 😉
you can start with just python + html + css
and then add js to this mix

backend is a deephole though, and frontend is not that small too

[sinful narwhal]

Guys me has a question
Should I invest my time to learn Django only

Like become a expert in it only

[vestal hound]

as opposed to?

[sinful narwhal]

Is it worth full and will it get me a good job online

[vestal hound]

well

it depends on where you are

but

there are defo places you can get a job by being good @ Django

[sinful narwhal]

No that's the thing I want a online job so my location does not matter

[vestal hound]

it does.

because even for remote jobs

[sinful narwhal]

In my country using technology is like a taboo

[vestal hound]

there are many companies which care about timezone

[sinful narwhal]

True....

[vestal hound]

there may also be other restrictions

based on country of origin

[sinful narwhal]

...

Anyways let's ignore that

Here

Should I learn Django

Or something else

Like game dev

In C++/C# or something like that

[vestal hound]

...it depends on your interests...?

and aptitude, of course

[sinful narwhal]

Or learn data analysis

See me has had one interest always and that is technology and coding

Python gave me that

Now me is finding one skill to specialise in python

So I need to find one thing that is extremely worth it

And does not need math like machine learning

[dusk portal]

any good yt tut or anything , so i can learn to make cart system and cookies for my site

[inland oak]

what is this country out of curiosity

i heard only about north corea like that

[dusk portal]

any good yt tut or anything , so i can learn to make cart system and cookies for my site

@inland oak

[sinful narwhal]

Rather not tell because of privacy

[dusk portal]

i want to be good in django now

[dusk portal]

u can tell country he isnt asking ur city

[sinful narwhal]

@dusk portal just search it up on YouTube and find one

[inland oak]

well, suit yourself

[dusk portal]

many are trash they r 2018-2019 using

and idk

ajax

[sinful narwhal]

Well you won't find one that was made yesterday

Learn also need modification

Learn the 2019 format
Read the doc
And recreate a new one with your own imagination and hard work

Read the doc for the new 2021 one*

[gentle ingot]

When linking things in flask, do i have to use the url_for function? I found that just stating the app route function name works.

[thorn igloo]

what do you mean by "when linking things"?

[gentle ingot]

href="{{url_for('index')}}" vs href=index

[gritty cloud]

exposing to the public you mean?

[thorn igloo]

you're saying the second option works?

[gentle ingot]

yep

[thorn igloo]

let me try it

[gentle ingot]

I did it for my website. Now im working on a blog following codemy and they are using url_for. Didnt know if it made a different.

It even works for longer paths. So like on my website, youll go to ...com/rps/paper and itll take you back to ...com/

[desert estuary]

i refactored it a little bit

@app.route('/',methods=["GET","POST"])
def login():
   if current_user.is_authenticated:
      if Admin:
         return redirect(url_for('admin'))
      elif Students:
         return redirect(url_for('user'))
   form=Login_formcall()
   if form.is_submitted():
      if form.email_user.data.split('@')[1]=="direwa.com":
         if Admin.query.filter_by(email=form.email_user.data,password=form.password.data).first():
            # global y
            # y=Admin.query.get(form.email_user.data)
            login_user(Admin())
            return redirect(url_for('admin'))
         else:
            flash("you don't exist")
      elif form.email_user.data.split('@')[1]=="ecolewa.com":
         if Students.query.filter_by(email=form.email_user.data,password=form.password.data).first():
            # global x
            # x=Students.query.get(form.email_user.data)
            login_user(Students())
            return redirect(url_for('user'))
         else:
            flash("the User doesn't exist")
   return render_template("Layout_log.html",form=form)

the first part doesn't seem to work

if current_user.is_authenticated:
      if Admin:
         return redirect(url_for('admin'))
      elif Students:
         return redirect(url_for('user'))

[desert estuary]

that's what they did in our school and guess what they fucked us up fr

[gentle ingot]

whats the code

[thorn igloo]

wait, i used quotes

[gentle ingot]

yeah you dont need those lol

[pulsar bloom]

Hello! Im kinda new to python and i would like to ask how to make a chrome extension with python?

[thorn igloo]

still getting the same thing without

[pulsar bloom]

Like a machine learned model to be integrated in a chrome plugin/extension

[gentle ingot]

thats weird

heres my source code and my website is quailware . net

https://github.com/msrogers2015/website

[thorn igloo]

i think it works cause your route has the same name path

it's not necessarily referring to the python function under the route like url_for does

[gentle ingot]

Okay. Thanks

I should probably update that. And my css files.

[summer cairn]

hi, i refactored my structure, and changed main.py to init.py . confirms it works locally but still getting this error on linode: https://paste.pythondiscord.com/ohedabejir.yaml

it's still unable to find autotrader module for some reason. here is my folder structure:

[desert estuary]

you installed autotrader

[summer cairn]

autotrader is actually a folder in my project

[summer cairn]

in my init, i need to import some stuff from it. it's failing on this import statement:
from autotrader.main import create_app

[desert estuary]

mm idk dude

[summer cairn]

it works locally, but it doesn't work when i push to linode

[native tide]

It becomes a public API

[warped heart]

is there a reason to why sphinx randomly exits after 2%?

it occurs when i use an addtional html file

{% extends "!layout.html" %}
{% block extrahead %}
    <script async src="arc-url"></script>
{% endblock %}

ah nvm i fixed it

just needed to remove extends

[jaunty magnet]

I'm confused about the value of color in the DOM. I created a button element and assigned it a hexidecimal color; however, when I console.log what the element.sytle.backgroundColor is, i get a rgb() value?? This is significant to me because i was putting in a conditional later on that would see if (e.style.backgroundColor === "#00000"), then do this, but I think that conditional isnt workign because of how its changing from hex to rgb in the DOM.

[gritty cloud]

you would need to host it then

see https://replit.com or https://heroku.com

[native tide]

I know that

I need to do it from the RDP

suppose you developed an api on your local machine

and you want your local machine to be the host

how do you do it ? @gritty cloud

[gritty cloud]

well first

get an external ip

buy a domain from someone

make sure ur computer will be running 24/7

ensure that you configure your dynamic, external ip (it will probably be dynamic) to act like a static one so that you don't have to type a different url the next day

and link it with your bought domain

a lot of pointless work imo

its like if you want electricity, you will go and build a power plant, configure wirings, and then deliver it to your house

@native tide

[native tide]

I have a bought a remote desktop from obh, so it has a domain and an ip obviously

And the ip is static

i want to start learning web development. should i learn javascript first, then html and css?

it never changes

[native tide]

Let me ask you this

I have the domain

and the Remote Desktop has an IP obviously

Are you saying that the only thing left ( after running the API on localhost ) is to route the requests to that domain to localhost ?

[gritty cloud]

im not entirely sure :/

typically i just deploy on cloud

i feel that it is too much for too little to deploy on your local machine

[native tide]

The issue is my database 😦

Because I have a discord bot

And it's running on a remote desktop

and the bot's db is file based

Which is a problem

so I need an api to fetch data from that database

Unless you have another option

I want to keep eveything in one place

And if I move to a server based db

It's going to be a major refactoring 😒

So if you have an idea

please let me know

[warped heart]

why not host your database somewhere else?

if you used a db which is apart of the Sqlalchemy ORM the rewrite shouldnt be to bad

[native tide]

I can't use an ORM because it's blocking

the bot is async

I haven't found an async ORM the last time I checked

I saw SQLAlchemy had something in beta

Idk if they released it

but where will I host the db ?

I don't see how Sqlalchemy ORM will solve my issue

[median cosmos]

Hi all, I am working on a project in Django and I have a slightly different structure than what I saw in all the tutorials I applied. It's all about "django admin".

Please all, If there is someone can helps me and has the time to do so, please send me a private message. Or at least mention me here.

Thanks in advance.

[warped heart]

use an async version then?

like aiosqlite

asyncpg

[native tide]

So you're suggesting, refactor everything I have to use asyncpg, host the database on a server, then make an api and host it ( on digital ocean for example, and make that api query the db ? )

[quick cargo]

alchemy is async since 1.4

see https://docs.sqlalchemy.org/en/14/orm/extensions/asyncio.html

[ivory bolt]

what's up channel

[native tide]

So it got released finally

[native tide]

Anyway that's not the problem

I'm just trying to find the best solution here

If you want, I can tell you what the problem is again

And you tell me what you think

[quick cargo]

well reading up on your previous message You should switch to a proper db rather than files (if im reading that correctly)

doesnt have to be a server setup

Sqlite would be enough

[native tide]

No it's not a file

It's an Sqlite db

[quick cargo]

Basically if you want to keep the sqlite setup

I would advise writing a single controller that both things interact with

otherwise

use a server based DB

e.g. Postgres, MySQL, etc...

thats about your only reasonable way

[native tide]

Because opening up an IP is not advised ?

And making it public is just a pain in the neck

?

[quick cargo]

well not really, but the fact that SQLite is only really designed to be used by a single process at once on disk

[native tide]

At least, the way I'm thinking of

[quick cargo]

so if you have multiple things open the db you run into all sorts of issues with locks and performance etc...

personally i'd just bite the bullet refactor it to be an ORM maybe and then you can switch to what ever backend you like really without having to rewrite everything again in future

but You will likely have to refactor the code at one point or another, so might be better to just get it over and done with

[native tide]

And then once the refactoring is done and host the database on a server, I can just then use any service to deploy apis (like AWS' chalice or DigitalOcean's App platform) and link that API to the hosted server ?

[quick cargo]

pretty much

[native tide]

Well, I guess I'll bite the bullet like you said

Thanks a lot guys !

[nimble loom]

I don't know what's wrong.. can someone help me?

what's wrong in this please? 0.0

[lone locust]

Hey guys, is there any worthy alternative for django-allauth? Or maybe allauth is still viable solution for user authentication?

[opaque rivet]

@nimble loom firstly, exactly as your error states, you need to set the queryset class variable of your view.

Secondly,

!code

[lavish prism]

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

These are backticks, not quotes. Check this out if you can't find the backtick key.

[ivory bolt]

if you're fetching data from some model, you need a QUERYSET

in your (I'm guessing class-based-view), write queryset = Model.objects.all()
where model is the name of your db model

[summer cairn]

FYI - finally figured it out. i needed to import package.file rather than just import file...😮‍💨

the serotonin rush after finally figuring out a bug after 3 days 🤤

for anyone else trying to get their flask app onto linode, use their tutorial: https://www.linode.com/docs/guides/flask-and-gunicorn-on-ubuntu/ , and be sure to import package.file rather than import file within your scripts lol

[inland hearth]

django is fun

[dusk portal]

any experienced django dev here i want some strong suggestion's

i have completed corey schafer's playlist , django begginer those 10 docs and have learned many topic's i have made a todo app , user sign up sign in forgot password change password reset and with profile part and stuff a blog app , now i wanted to learn advanced topics like cookies cart and payment management big projects advanced things , what should i do from where should i learn

[wooden ruin]

Look into stripe for payment things and I'd suggest getting to know djangorestframework, token authentication and websockets

[dusk portal]

from where any yt tutorial

or only docs

idk react and i have 0 knowledge of js

how can i learn rest framework then for applying react vue and angular

if idk js

[wooden ruin]

Djangorestframework has awesome documentation, so I'd suggest to learn from there. Once you know how to work the backend it's time to learn front-end, at least the basics of js

[dusk portal]

ohh bro and how can i learn stuff of cookies

[wooden ruin]

I'm a vuejs guy but you gotta have experience with js/ts before learning a ui framework

[dusk portal]

bro but question is how will i do

rest framework

cez in that

we use 1 page technology

idk that so how can i learn

rest framework

[wooden ruin]

if i recall correctly there is a udemy course regarding djangorestframework

[dusk portal]

ohk then im gonna learn rest framework

after making 1 ecommerce proj

[wooden ruin]

if you want to learn drf or channels CodingEntrepeneurs on youtube has some nice yt videos

[dusk portal]

whats advantage of learning rest framework @wooden ruin in there we can use payment gateway

what is drf

[wooden ruin]

drf = django rest framework

[dusk portal]

ohh

[wooden ruin]

drf makes it easy to build an api

[dusk portal]

ohh got it

[wooden ruin]

and you can use stripe for payment things

its a library iirc

[dusk portal]

1 suggestion last pls @wooden ruin

[wooden ruin]

ok

[dusk portal]

so i have covered many things now so i have 2 option now i should continue learning django or go to drf , what should i do i have now a good exp of django framework should i go to learn drf now or make e-commerce site in this simple django only

how to mandle cookies

what is asgipy wsgipy

i dont saw any use of them

[wooden ruin]

i suggest learning djangorestframework because it's widely used among backend developers

[dusk portal]

ohk then let's crack it

within a month

[wooden ruin]

asgi stands for asynchronous server gateway interface

[dusk portal]

10 to 12 hrs a day

[wooden ruin]

its a devops thing iirc

ok sounds good

[dusk portal]

i never used it

[wooden ruin]

django uses wsgi by default when u deploy (i.e. using gunicorn when setting up for production). when you use websockets for django channels it requires asgi which provides support for asynchrous stuff (the counterpart for this is daphne as opposed to gunicorn)

[dusk portal]

cookies part is also ez in rest framework

oh

it means im going right rn

i didnt missed anything

sounds good

cez i have not learned deployment so ohkk

[wooden ruin]

yes devops is important to learn, at least the basics i'd say

[dusk portal]

i mostly play with my code

i learned to delete object in model

so for fun i added delete user option

and deleted the main admin (owner )

[wooden ruin]

yea its really nice getting to know all those cool features

[dusk portal]

then needed to rerun migrations and make db

learned in 1 month

[native tide]

hey

[dusk portal]

hello how can we help u

[native tide]

hey

[wooden ruin]

btw look into using disabled in the default django user model instead of delete, the docs say that deleting users can tend to break relationships

[dusk portal]

[clever bronze]

Can anyone help me with django?
I just started learning

[raw compass]

Best to put your question in the chat. Better if you put a formatted code sample.

[clever bronze]

Ok sure

So basically i just started
And i was having trouble printing the data from my db on the webpage

I've almost tried everything but it just wouldn't print whts inside the django template for loop

this is views.py

from django.shortcuts import render

from .models import Post
# Create your views here.
def home(request):
    data = Post.objects.all()
    print(data)
    return render(request,'index.html',{"posts": data})
    # return render(request,'index.html',{})

index

{% for post in posts %}
here
{{ post.title }}
{{ post.content
}}
{% endfor %}

here i've tried using <p> <li> and even tried creating a table
but the output is not visible

Ping me if u want anyother file

[raw compass]

I'm a little rusty with django.

I was finding an example to compare though I found one with class based views https://docs.djangoproject.com/en/3.2/ref/class-based-views/generic-display/

[clever bronze]

Ya its seem similar

Hey wait
It worked😶
Automatically

But it was not woeking yesterday
I wasted 2-3hrs on this stupid thing

[dusk portal]

@clever bronze how can i help

[clever bronze]

@dusk portal its solved
thanks btw

[dusk portal]

Ohk

Np

[desert estuary]

it doesn't submit in the database

@app.route('/',methods=["GET","POST"])
def login():
   form=Login_formcall()
   if form.is_submitted():
      if form.email_user.data.split('@')[1]=="direwa.com":
         if Admin.query.filter_by(email=form.email_user.data,password=form.password.data).first():
            ADmin=request.form["email_user"]
            session["Admin"]=ADmin
            return redirect(url_for('admin'))
         else:
            flash("you don't exist")
      elif form.email_user.data.split('@')[1]=="ecolewa.com":
         if Students.query.filter_by(email=form.email_user.data,password=form.password.data).first():
            current_student=Students.query.filter_by(form.email_user.data)
            session["student"]=current_student
            return redirect(url_for('user'))
         else:
            flash("the User doesn't exist")
   return render_template("Layout_log.html",form=form)

i tweaked the code a little bit

def get_data():
   formi=Userform()
   if "student" in session:
      current_student=session["student"]
      if formi.validate_on_submit:
         new_change=Students.query.filter_by(email=current_student)
         new_change.fullname=formi.fullname
         new_change.personal_email=formi.personal_email
         new_change.dialling_num=formi.dialling_num
         new_change.branch=formi.branch   
         new_change.occupation=formi.occupation
         db.session.commit(new_change)
   return render_template("User/edit_page.html",form=formi)

[desert estuary]

so the thing is the submitfield didn't work

def get_data():
   formi=Userform()
   if "student" in session:
      current_student=session["student"]
      if formi.is_submitted and request.method=="POST":
         # current_student.fullname=formi.fullname
         # current_student.personal_email=formi.personal_email
         # current_student.dialling_num=formi.dialling_num
         # current_student.branch=formi.branch   
         # current_student.occupation=formi.occupation
         # db.session.commit()
         print(current_student)
         return redirect(url_for('user'))
   return render_template("User/edit_page.html",form=formi)

[desert estuary]

i made an else statement and i loged in when i click on the edit profile i stay in the same page
isn't the student in the session even tho i added him in the login

i click on it but nothing happens

[thorn igloo]

what are you saying here? that the get_data() function is never reached?

[desert estuary]

exactly

[thorn igloo]

so the problem is not here then

[desert estuary]

should i pass the whole code

[thorn igloo]

no, just the one that's linked to the button

[desert estuary]

the code that's linked with the link is the one i showed now
this is the view function that's linked with the button

{% extends "Layout_user.html" %}
{% block content %}
<section class="content">
   <h2 id="welcome">Welcome to your Dashboard</h2>
   <div class="info">
      <div class="userinfo">
         <img src="{{ url_for('static',filename='img/imageblank.png') }}" alt="profilepic">
         <a href="{{ url_for('get_data')}}">edit profile</a>
      </div>
   </div>
</section>
{% endblock %}

[thorn igloo]

what's the route for it?

what happens when you visit it manually?

[desert estuary]

@app.route('/user',methods=["GET","POST"])
this is the route for the user or the student 
@app.route('/user/edit_profile',methods=["GET","POST"])
this is the route for the edit page to edit the info

[thorn igloo]

what happens when you visit here /user/edit_profile'

[desert estuary]

i get back to user/ i can't acces the page

[thorn igloo]

it instantly redirects?

[desert estuary]

yeah

[thorn igloo]

return redirect(url_for('user'))
comment out this line and try again, tell me what happens

[desert estuary]

it went to the edit page

[thorn igloo]

are you using flask_wtf?

[desert estuary]

yeah

wtforms

from flask_wtf import FlaskForm
from wtforms import BooleanField,PasswordField,StringField,RadioField,SubmitField,SelectField
from wtforms.fields.html5 import TelField 
from wtforms.validators import DataRequired, Email

class Login_formcall(FlaskForm):
   email_user=StringField('Username',validators=[DataRequired(),Email()])
   password=PasswordField('Password',validators=[DataRequired()])
   remember=BooleanField('Remember me')
   submit=SubmitField('Login')

class Userform(FlaskForm):
   fullname=StringField("Fullname",validators=[DataRequired()])
   personal_email=StringField("Email",validators=[DataRequired()])
   dialling_num=TelField("Tel/num",validators=[DataRequired()])
   branch=RadioField("Branch",choices=[("Dev","Dev"),("Des","Des")],validators=[DataRequired()])
   occupation=SelectField("Occupations",choices=[("Work","at work"),("Freelance","freelance"),("Unemployed","no job"),("Studying","Still studying")],validators=[DataRequired()])
   SUB=SubmitField("Submit")

also the submit in the userform doesnt work

cuz when i enter data and submit it it doesn't push to the database

[thorn igloo]

change this if formi.is_submitted and request.method=="POST":
to

if formi.validate_on_submit():

[desert estuary]

tried it but not nothing i've been stuck in this prob for 3 days now

[thorn igloo]

what do you mean?

i'm asking you to try it now

[desert estuary]

i just did again and nothign

[thorn igloo]

hop in voice and show me what's happening

[sick glacier]

where can i get django related help?

[thorn igloo]

i'm in voice help 0

[desert estuary]

okay wait

im there

[opaque rivet]

@sick glacier here

[sick glacier]

@opaque rivet : thanks

[desert estuary]

uh hey ```File "C:\Users\Hamza\Desktop\PFA\Flaskiproject\routes.py", line 39, in user
return render_template("User/Homepage.html",student=current_student)
UnboundLocalError: local variable 'current_student' referenced before assignment

```py
@app.route('/user',methods=["GET","POST"])
def user():
   if "student" in session:
      current_student=Students.query.get(session["student"])
   return render_template("User/Homepage.html",student=current_student)
```how can i correct this

[summer cairn]

that's happening because if that if statement is false, the function would not be able to return current_student since it wouldn't be defined. you can either:

• assign it a dummy value above the if statement, or
• tab over the return statement so that it's within the if

[native tide]

I have made a location tracker but I am getting this error

I am getting those yellow lines

[warm igloo]

and what does your editor say those yellow lines mean?

when you put your cursor on them, or in your Problems tab (if this is vscode)

_name_ should be __name__ btw

[warm igloo]

and services_operator is typoed in the one highlighted

and your import can't be resolved, so look at how to do imports and check to make sure you've set up phonenumbers correctly to be imported

So you have 2 typos and phonenumbers isn't imported because you've not created it, installed it, or something.

_main_ should also be __main__

[native tide]

I had done pip install phonenumbers

[native tide]

Yes I did it

[warm igloo]

so is the only error you have now about phonenumbers?

[native tide]

yes

[warm igloo]

still fix _main_ to __main__ (no error showing cause its a string being checked but check out https://www.freecodecamp.org/news/if-name-main-python-example/ )

From where you think you installed phonenumbers module, run pip list

You should really be doing all of this in a venv btw because otherwise you're installing modules at the global level.

[native tide]

venv?

@warm igloo

[warm igloo]

https://realpython.com/python-virtual-environments-a-primer/

Can also checkout poetry or pipenv

[desert estuary]

can you use f'string' in jinja

<h1>{{ print(f"fullname:"{student.fullname}) }}</h1>
<h1>{{ print(f"personal-email:"{student.personal_email}) }}</h1>
<h1>{{ print(f"dialling-number:"{student.dialling_num}) }}</h1>
<h1>{{ print(f"branch:"{student.branch}) }}</h1>
<h1>{{ print(f"occupation:"{student.occupation}) }}</h1>

[warm igloo]

you .. don't need to

just put the variable

jinja templtes are interpolated

[desert estuary]

i wanna write something beforehand

fullname: x

[warm igloo]

then write it plaintext

[native tide]

Do I need double underscore in
if __name__=="__main__":

[warm igloo]

everyting inside {{}} gets printed

yes, dunder on name and main

[warm igloo]

<h1>fullname: {{student.fullname}}

[native tide]

@warm igloo

[desert estuary]

oh shit yeah eya im dumb @native tide thanks

[native tide]

??

[warm igloo]

they mean me lol

but you're welcome

[native tide]

see this @warm igloo

What should I do of those yellow lines

[wicked pier]

this might be a better place than general to ask for flask/celery help haha. please let me know if not

trying to set up some way to see print statements.
I have a logger set up for the tasks, where it's just a matter of get_task_logger, but I'm not sure what I need to do to see print statements in Flask routes

actually...may have found the answer already

I think it lies in Flaskland somewhere as opposed to celery

[native tide]

help me with this pls @wicked pier

yellow lines

[thorn igloo]

what does it say when you hover over it?

[wicked pier]

lol what yellow lines

[native tide]

@thorn igloo

[thorn igloo]

ok, what happens when you run your program? does it run or not?

[native tide]

ok wait I will send you

ohh its working now

srry

But the yellow lines are still there

[thorn igloo]

ok, if it's working ignore the lines

you don't really have a problem

[eternal blade]

It's probably the linter doing a bad job

[haughty edge]

Needed some beginner help with Python / Django:

Is it possible for user to create two objects from the same form? For example, am trying to create a to-do list webapp. When a user creates a task, they should have the option to:

1. Choose from existing tags (another object that has many:many relationship with 'task', or

2. Create a new 'tag' if the existing ones don't suffice.

Is it possible to do this from single form? Currently, when I create the form for 'task' using Model form, all it allows the user to do is (1).

[desert estuary]

how can i eliminate this and make instead of choose file make it like a field to drop items in

[hollow apex]

Hello so, idk whats the problem here

def register(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)
        if form.is_valid:
            username = form.cleaned_data.get('username')
            messages.success(request,f'Account created for {username}!')
            return redirect('blog-home')

    else:
        form = UserCreationForm()
    return render(request,'users/register.html',{'form':form})

even tho I have used cleaned_data after is_valid, it still gives me this error

I hate programming, I found it, its the "()" on is_valid

[wooden ruin]

Does Django have support for mongodb?

[desert estuary]

form.is_valid()

[eternal blade]

I think there is a external library you need to use if you want to use Django with mongodb

[desert estuary]

yes

btw

db.add_column(upload)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'SQLAlchemy' object has no attribute 'add_column'

[languid raptor]

I've not tried mongo as the backend for Django, but I did investigate for a project: Djongo https://pypi.org/project/djongo/

[wicked pier]

what is the standard way for terminating a task using celery?

is it really revoke(task_id, terminate=True, signal='SIGUSR1')? that seems really obtuse

like, I'm looking for something which doesn't abuse signals, like how they expect people to be able to end a running task

this didn't seem to give me anything definitive:
https://docs.celeryproject.org/en/latest/userguide/workers.html#revoke-revoking-tasks

[warm igloo]

what do you mean doesn't abuse signals?

The default is sigterm and sigterm can be handled or ignored. The TERM goes to your task, and it is up to your task to handle it gracefully (or not-gracefully depending on what you want to do)./

[eternal frigate]

where is homepage.html file located? is it at ../myapp/templates/myapp/homepage.html? try referencing it with myapp/homepage.html. "myapp" is a placeholder for your app name. In code templates path are relative to some directory defined in TEMPLATES setting, the default setting makes django search templates in ../myapp/templates directory for all installed apps, to avoid template name collision between different apps you create a subfolder with app name and put your templates there, so you reference it with appname/mytemplate.html.

i am not getting any error but the form_name_view method doesn't seem to work

sorry for the mess!

[eternal frigate]

what does not works? you can access it from browser?

[nova pewter]

yeah the web page opens but when i submit it doesn't print out ("verification done')

i am just trying to check if the "POST" method works

[eternal frigate]

and the form does not displays any error?

[nova pewter]

yep no error

when i submit it doesn't do anything

[eternal frigate]

how is your form template? you followed django's tutorial?

[nova pewter]

i am learning from a course on udemy.

form template is working fine

btw the latter is the forms.py file

and above it is views.py

[desert estuary]

class Uploading(FlaskForm):
   uploadfile=FileField("upload",validators=[FileRequired(),FileAllowed(["jpg","png","pdf","txt"])])
   Submitting=SubmitField("Submit")


@app.route('/user',methods=["GET","POST"])
def user():
   if "student" in session:
      current_student=Students.query.get(session['student'])
      print(current_student)
      form=Uploading()
      if form.validate_on_submit():
         current_student.upload=form.uploadfile.raw_data
         db.session.commit()
         return redirect(url_for('user'))
   else:
      return redirect(url_for("login"))
   return render_template("User/Homepage.html",student=current_student,form=form)

   def __init__(self,fullname,email,personal_email,password,dialling_num,branch,occupation,upload):
      self.fullname=fullname
      self.email=email
      self.personal_email=personal_email
      self.password=password
      self.dialling_num=dialling_num
      self.branch=branch
      self.occupation=occupation
      self.upload=upload

   def __repr__(self):
      return f'Student:{Students.id} {Students.fullname} {Students.dialling_num} {Students.branch} {Students.upload}'

so this is my code and when i try to submit some file to the database it doesn't wanna be pushed to the data base

[desert estuary]

what do you mean by read

you wanna present the data right

i guess you should do this

fileread = filesubmit.file.data()
```since it doesn't have such thing as read and you want to display the data that you got from the field right

if not and you want to get it from the database i guess you should do something like this

x= Filesubmitproject.query.filter_by(file=fileread)

at least from what i understood

[warm igloo]

what is your .read() line I didn't see it in the code above

[mossy osprey]

Not sure if this is the place to post this, but any thoughts?

[warm igloo]

Looks like your xpath is wrong and that element doesn't exist?

[mossy osprey]

Wait what exactly do those words mean haha?

[warm igloo]

Off top of head I think you need filesubmit.file.data.read()

let me go look at a flask app I have with a file upload, see how I did it cause I can't remember atm

dude, I'm an "architect" and I've spent hours recently looking for a single ' that was effing up my world. It happens to all of us. 😄

I'll go find my code too just to be sure

wait did it work?

lmfao

welcome

pulled that shit out of the air

haha been there

uhoh

well, they're bytes yes

you gonna store them as a blob in the db?

make sure you save a filename or at least mimetype with them too

cause that will matter

I have in the past as another column. Main thing when you want to print out the blog back to an image, you'll need to say "oh save this to disk as a .jpg" or "stream this to the client as a .jpg". But if your clients can upload all those different file types, how will you know what to send them back?

For instance, you could store the original filename or extension and just use that when you spit it back out. And if you're streaming it back to them, you may need to set the Content-type to image/jpg so the browser knows what to do.

But before you even go there, give it a try and see what the hell happens

🙂

[mossy osprey]

yayyyy!!!

[warm igloo]

@mossy osprey Did you figure out your xpath syntax?

[mossy osprey]

Lmaooo all good @fair shale

[mossy osprey]

Nope. However I apparently don't have an xpath issue anymore. My issue now is: ```selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/div[4]/div/div/div[2]"}

[warm igloo]

same issue

[mossy osprey]

So just a bit of a context. I'm trying to write a simple script that returns a list of followers from one of my Instagram accounts. So I don't think there's an Instagram Python API that I can use, I'm just using selenium.

Bruh I'm blind.

I saw the xpath after you just pointed it out @warm igloo. Anyway what exactly is an xpath?

[warm igloo]

so, you're trying to select some element on the page and it is saying "sorry, that isn't there"

you need to catch that exception and do something accordingly

[mossy osprey]

Oh so the element "/html/body/div[4]/div/div..." doesn't exist for some reason right?

[warm igloo]

xpath is just a syntax for selecting elements from a tree of nodes like in html or xml

right, I'm guessing you're using selenium commands and trying to find some div/button/element/whatever and this is saying "you're wrong, that's not there"

[native tide]

Hey, I'm working on one thing regarding Ubisoft and I need to connect into account using email and password and get authorization, but unfortunately I'm struggling with it. I found the same thing that I need in C# but unfortunately I dunno it and I can't really make it in python for some reason, any ideas?

var basicCredentials = Convert.ToBase64String(
              Encoding.UTF8.GetBytes(ConfigurationManager.AppSettings["mail"] + ":" + ConfigurationManager.AppSettings["password"]));

            var request = new HttpRequestMessage
            {
                Method = HttpMethod.Post,
                Headers = {Authorization = new AuthenticationHeaderValue("Basic", basicCredentials)},
                RequestUri = new Uri("https://public-ubiservices.ubi.com/v3/profiles/sessions"),
                Content = new StringContent("{\"Content-Type\": \"application/json\"}", Encoding.UTF8,
                    "application/json")
            };

[warm igloo]

keep in mind for instagram their HTML might not be rendered and may all be client side generated with JS so you'll need to make sure whatever you're using as your selenium browser engine is rendering the JS of the page too (I think by default it should be doing that but I can't recall atm)

[mossy osprey]

I see. So how do I know what specific button /html/body/div[4]/div... corresponds to? I will admit I didn't write this script originally. Someone else did, and I'm just using it mostly as a learning experience lol.

[warm igloo]

@mossy osprey do you have some code you can share?

[mossy osprey]

sure

[warm igloo]

!code

[lavish prism]

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

These are backticks, not quotes. Check this out if you can't find the backtick key.

[warm igloo]

just in case

[mossy osprey]

Do you want me to send the entire thing or just a fraction? (the entire thing is 73 lines)

[warm igloo]

@native tide What are you building with that?

!paste

[lavish prism]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[warm igloo]

Put the 73 lines there

or repl.it or something like that

I write a lot of spiders using selenium, beautifulsoup, etc so hoping I can help you

[native tide]

I'm working on script that will login into account and scrapes stats of it

[warm igloo]

Actually something I need to remind both of you: make sure you are not violating the TOS of the site you are trying to scrape.

[native tide]

And I need to get auth of that account as well

[mossy osprey]

https://paste.pythondiscord.com/ijuvenozuy.py @warm igloo Lemme know if that shows up

[mossy osprey]

If I may ask, what kind of account? Cuz i'm doing like almost the same thing lmao (mine is instagram)

[native tide]

Ubisoft

[native tide]

There's explained everything

[native tide]

What's ur problem?

[mossy osprey]

just trying to return a list of users from one of my accounts. It's more of a learning experience/really simple project. Nothing deeper than that right now.

[warm igloo]

@native tide You can make those same calls with python. Take note of the steps and the headers and make the same request to the same url. Try to write the code and I'll try to help you, but I can't do a direct translation for you.

[native tide]

I have tried it using many ways but I have no clue tbh

email = ""
password = ""

r = requests.post("https://public-ubiservices.ubi.com/v3/profiles/sessions", auth=(email, password))
rData = r.json()
print(rData)

And other ways that are described in docs (https://docs.python-requests.org/en/master/user/authentication/)

[warm igloo]

@mossy osprey Since you borrowed this code and its not yours, what could be happening is that particular layout has changed and the xpath is now incorrect cause the elements on the page you're looking at are different now.

So for instance the page could have been "<div>Hello Swift!</div>" last week but this week is "<div><span>H</span>ello, <em>Swift!</em></div>" this week so the code says "gimme the div at this xpath" and of course .. the path is now different.

[mossy osprey]

Ahhhh that makes sense. So how would I be able to retrieve the correct "layout" and translate that into workable code?

[warm igloo]

Usually how I do it is 'Inspect Element' in my browser. Depending on which browser you can see the xpath at the bottom of the console (though not in xpath syntax necessarily).

Ooh, in Firefox I can right click on an element in the inspector and then copy the xpath from there: /html/body/header/div/div[1]/a[2]/span for instance that came from an element on a page I was just on

So I went to instagram and popped open the followers modal and selected the xpath of the div containing my list of followers: /html/body/div[5]/div/div/div[2]

Or rather this: /html/body/div[5]/div/div/div[2]/ul/div is "further down" and closer to the data

Reminder: make sure the script you're making is opening the modal window too or the element you're searching for won't exist

tricky stuff scraping from javascript heavy front ends

[mossy osprey]

@warm igloo Did you do this in firefox or chrome? rn, i'm doing this in chrome

I could try in firefox

[warm igloo]

I'm in FF right now. Don't have Chrome on this box as its just my gaming box. 🙂

I'm sure Chrome is similar though

[native tide]

Any ideas on this? I dunno how to make these same requests since I barely understand csharp

            return JsonConvert.DeserializeObject<UbisoftToken>(await response.Content.ReadAsStringAsync())!;
        }

This is whole function

[warm igloo]

oh yeah you'll need to add all those other headers to your python too, not just the auth

the appid, uplay one, etc

I'm looking for a learning partner who would like to contribute to my Django web app project by creating a modern design for a simple dashboard.
I'm a back-end developer and not experienced with JS nor have the design skills for sexy CSS.

If you would like to help please send a DM with your portfolio (if you have one, if not that's fine too)!

[native tide]

How should I do it?

[mossy osprey]

@warm igloo so I did what you said: right-click, inspect element. But this doesn't like an xpath to me?

I took your advice and logged into Instagram on Firefox ^^

[native tide]

https://i.imgur.com/hlbfATB.png

Or u can use some addon such as ChroPath

[native tide]

headers = {
    'Ubi-AppId':'880650b9-35a5-4480-8f32-6a328eaa3aad',
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.190 Safari/537.36',
    'Ubi-RequestedPlatformType':'uplay'
}

r = requests.post("https://public-ubiservices.ubi.com/v3/profiles/sessions", auth=(email, password), headers=headers)
rData = r.json()
print(rData)

I tried this but it still doesn't work

Normally there's Authorization in headers too and there's the auth token but I need to login using email and password in this case

And I'm getting The Authorization header is missing error since I don't have any there

I am unable to install any python module thru pip from Anaconda prompt

[inland oak]

I remember that conda has different ways to install the same.

pip is replaced to conda in conda

https://anaconda.org/anaconda/mysql-connector-python

something like that perhaps

https://www.youtube.com/watch?v=z0jVsEuuLLc

according to this guide, you still need to use pip though

just in different console

[hybrid dome]

why does it says template not found

im new to flask ;-;

[ionic raft]

You need a templates folder

[hybrid dome]

ohh new folder?

[ionic raft]

yah...

[hybrid dome]

um alright but where

[ionic raft]

In root should do it

Flask looks for /templates/ for all templates

[hybrid dome]

oh

[ionic raft]

It will make sense later. And it makes it easier to organize files as the project grows.

[hybrid dome]

um-

not working

Hello guy, is there any module for bypass cloudflare? I tried this module https://github.com/VeNoMouS/cloudscraper but it doesn't work.

[hybrid dome]

nvm fixed

how do i make a button in html when clicked does something using python code

[inland oak]

in pure html, you make submit form https://www.w3schools.com/html/html_forms.asp
which will make POST request to the same page you are in. it will allow you to execute python code

in flask where you are, you should use flask forms
https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-iii-web-forms

[hybrid dome]

im not making a submit form

[inland oak]

then you attach javascript to button

that makes fetch request to your python api

[hybrid dome]

wdym javascript

idk js

[inland oak]

as far as I know there are only two ways. I can't offer you third one.

[hybrid dome]

why

[thorn igloo]

he just explained that there are two ways??

it's either you submit a form or you make ajax calls from JavaScript

[tawny gazelle]

anyone know about this?

Hello,
I just have a simple question regarding Django administration. I know how it functions and have explored it a bit. Django Admin offered all sort of CRUD features directly into my database. Now I am supposed to build a simple web API for my client where I am supposed to do simple CRUD tasks. If Django Admin directly offers it, should I use the libraries that the django admin uses or do i need to write codes for the client myself? Also, for whom is Django admin targeted for? Is it for server people or developers only? Or can it be passed to the client? I have done alot of API's in NOdejs but I have recently started Django so I am a bit confused on the Django Administration. Any help would be appreciated.

[inland oak]

simple recommendation. don't use django admin as main thing for CRUD
django admin is targeting being used only by devs or moderators

[coarse dawn]

Hello everyone, I have simple, maybe not, question for Django CMS. I have a major error and don't know where to look. So the issue is following:

1. I am using Django CMS show_menu, using my own template etc.
2. I have a specific menu tree that I have on Django Admin panel with all pages and menu items, half of which are marked as they should not be visible in menu
3. When I open webpage that I am working on, it shows me menu and all items that are in that menu tree, like all of them, including the items, that have been switched off.

The tag i am using to show menu is following: {% show_menu 0 100 100 100 "*link to template*"%}
Could you please assist and tell me where could possibly error be? Thank you!

Hi ,
I am struggling with django errors, i tried many things to solve, but every time, i got a new one. Although i am doing same things in the video , i got an error message, i don't know why it is like that:

[native tide]

Bump

[marble topaz]

isnt that malicious

ur tryna make a account bruteforce

[native tide]

Um, what?

I'm trying to login into account lol

Using email and password instead of auth token

[marble topaz]

thats malicious pretty sure

[subtle hamlet]

assets = db.execute("SELECT symbol, action FROM account, SUM(shares) WHERE action = buy - SUM(shares) WHERE action = sell AS shares WHERE userid = ? GROUP BY symbol", session["user_id"])
i think it's not allowed to have multiple WHERE in SQL? there's a syntax error, how do i achieve this effect

i want to select the data from account table to get data for bottom

[raw compass]

Most SQL languages will allow a case statement that would do a if statement that will be more suitable.

For example in PostgreSQL

with processing (
SELECT 
  symbol, 
  CASE action 
    WHEN 'buy'  THEN shares 
    WHEN 'sell' THEN shares * -1 
    ELSE null 
  END as shares 
FROM account WHERE userid = ?
)
Select symbol, SUM(shares) from processing group by 1;

This is a combination of a CTE so I could logically seperate the query and do the group by afterwards as you can't always do it at once...

Hey, so I'm basically making script that logins into Ubisoft account using email and password, but I don't know how to do it.

headers = {
    'Ubi-AppId':'880650b9-35a5-4480-8f32-6a328eaa3aad',
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.190 Safari/537.36',
    'Ubi-RequestedPlatformType':'uplay'
}

r = requests.post("https://public-ubiservices.ubi.com/v3/profiles/sessions", auth=(email, password), headers=headers)
rData = r.json()
print(rData)

Normally there's Authorization: 'token' in headers and there's the auth token but I need to login using email and password in this case and I dunno how to write the syntax in that case. (I'm building a stat checker, not anything malicious or whatever)

hm

[gritty cloud]

You would first have to make a post to the login / signup url

[native tide]

this is an interesting channel

so what can i use to tell what should happen when someone clicks on a button with Python

[gritty cloud]

Then reuse the auth token they give you

[native tide]

considering the button was written in HTML and styled with CSS

[gritty cloud]

Assuming they use tokens amd not sessions

[native tide]

is Flask the way to go?

[native tide]

This is the "thing" that I need but in csharp, and I barely understand it so I'm really not able to convert it into python

        private static async Task<UbisoftToken> GetToken()
        {
            _httpClient.DefaultRequestHeaders.Add("Ubi-AppId", "2c2d31af-4ee4-4049-85dc-00dc74aef88f");
            _httpClient.DefaultRequestHeaders.Add("Ubi-RequestedPlatformType", "uplay");
            _httpClient.DefaultRequestHeaders.Add("user-agent",
                "Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3");

            Console.WriteLine("Connecting to the Ubisoft Servers.");

            var basicCredentials = Convert.ToBase64String(
                Encoding.UTF8.GetBytes(ConfigurationManager.AppSettings["mail"] + ":" + ConfigurationManager.AppSettings["password"]));

            var request = new HttpRequestMessage
            {
                Method = HttpMethod.Post,
                Headers = {Authorization = new AuthenticationHeaderValue("Basic", basicCredentials)},
                RequestUri = new Uri("https://public-ubiservices.ubi.com/v3/profiles/sessions"),
                Content = new StringContent("{\"Content-Type\": \"application/json\"}", Encoding.UTF8,
                    "application/json")
            };
            var response = await _httpClient.SendAsync(request);
            if (!response.IsSuccessStatusCode)
                throw new UnauthorizedAccessException("Unable to retrieve authentication ticket. Thanks ubisoft mf!");
            return JsonConvert.DeserializeObject<UbisoftToken>(await response.Content.ReadAsStringAsync())!;
        }

bro

[native tide]

like

yo

[gritty cloud]

As far as I understand this script makes an htp client with the necessary credentials then sends the request

Then throws an error if the request fails

[native tide]

Would u be able to show me the syntax of how it should be in python? I was trying to do this yesterday for over 3 hours but I have no clue

[gritty cloud]

I also don't lol

But you just would need to requests.get with the headers

[native tide]

That's what I tried

Many times using many ways

[gritty cloud]

¯\_(ツ)_/¯

Maybe ubisoft has a public api

[native tide]

Unfortunately they do not

[gritty cloud]

Hm

Anyone worked with Django channels? Does it generally require an ASGI server in production for the entire project?

I'm looking to create subscriptions with GrapQL to Django, but it looks like there's a lot of work on the backend to get that working.

[inland oak]

5 seconds of googling say its built ont ASGI

even its depended libraries are mentioned

https://channels.readthedocs.io/en/stable/

[dense slate]

Yea I've read it, I'm more curious about people's experience with it. How difficult it was to setup and get running in production, et.

what do you mean by debug is this context?

for him it is showing django

for me it is not

[thorn igloo]

let me check

[thorn igloo]

make sure your current active window is a python file

i tried it and the django option is there for me

[rocky ferry]

i didn't get bro

i did

still same

[thorn igloo]

you have the python extension installed?

[thorn igloo]

i it's returning it because that's what you are telling it to return

[inland oak]

there is actually an option to run django 😉

but it is not needed in my opinion

because there is option to run pytest ;b

debugging pytest is the only needed thing in my opinon

no point in debugging launched application

see how x wasnt affected

but the function needs to be called first before the change can happen, keep that in mind

return render_template(

liens=nb_links,
tables=[
output_f.to_html(

Anyone with a helping hand?

Consider me a complete noob because I totally don't how to do what I am about to say or even if I'm in the right place for it, can we upload images to some sort of a temporary server or website atleast 1 image per second with enough speed that discord can render it like a really low fps game in an embed yes this is a discord bot project idea

This is completely indirect to the discord.py library

Mate, this has got nothing to do with the library, just that this is for a bot. What I want to do is to upload an image to a web of sorts and be able to render it from discord with an embed. So is it possible/is there a website or library Which can help me upload an image to a database and handle it fast enough?

Oh

Thanks .. I'll try to do something,

It seems that string interpolation doesn't work?

def show_user_profile(username):
    # show the user profile for that user
    return f'User {escape(username)}'```

I get invalid syntax

What is your version of Python?

[pallid spade]

Python 3.9.6

from markupsafe import escape

@app.route("/")
def hello_world():

@app.route('/hello')
def hello():
    return "<p>Hello World</p>"


@app.route('/user/<username>')
def show_user_profile(username):
    # show the user profile for that user
    return f'User {escape(username)}'```

[tiny snow]

are you sure that's the version of Python that's executing this script?

[pallid spade]

Python 3.9.6

?

[tiny snow]

try py -3.9 that_scripts_name.py

or python3 that_scripts_name.py

[pallid spade]

Unknown option: -3

I am simply doing the official tut

[tiny snow]

no, do it without -3.9

either you do

py -3.9 hello.py

or

python3 hello.py

[pallid spade]

ModuleNotFoundError: No module named 'flask'

[tiny snow]

yeah you didn't install flask on your python 3.9 version

[pallid spade]

hmmm

ok....

[tiny snow]

do

pip3 install flask

or whatever you need to install it on linux

you're on linux, right?

[pallid spade]

no mac

[tiny snow]

well whatever

pip3 install flask

[tiny snow]

can you please do

from sys import version
print(version)

in your code and tell me what it says when you do

python3 hello.py

like what version of Python does it say

[pallid spade]

3.9.6 (v3.9.6:db3ff76da1, Jun 28 2021, 11:49:53)

and then there is this error of flask being unknown right

[pallid spade]

ModuleNotFoundError: No module named 'flask'

but flask works

I can do index and hello routes

but when is gets to the formating it says it can't do it

but I know it is available in this verison of python

[tiny snow]

yeah so, PyCharm starts python2 for some reason

and flask isn't installed for python3 for some reason for you

i don't know

are you in a virtual environment

[pallid spade]

yeah I am just bc I am following allow the tut

[tiny snow]

did it tell you to run these or something similar

https://stackoverflow.com/questions/31252791/flask-importerror-no-module-named-flask @pallid spade maybe follow this thread

I have no idea

[tiny snow]

maybe now it will work

since it says it's there

[pallid spade]

(venv) ~/PycharmProjects/flask-tut $ python3 hello.py

[tiny snow]

does it mean it worked?

[pallid spade]

there is no output

oh wait did you remove the line where it runs it like that

[pallid spade]

hold on I got a friend calling that is programmer

How can I detect when a javascript event object has finished propagating?

I'm writing a program that creates a virtual/proxy DOM in python to represent a living webpage. Whenever an event occurs in Javascript, its transmitted to Python which creates a proxy object representing the event, dispatches it, and then sends any DOM changes/etc triggered by the event back to javascript

So in Javascript, every time an event handler is triggered, it sends the event's data over to Python which fabricates a proxy of the event object. The problem is that a single event object in Javascript may trigger numerous listeners as it traverses its bubble chain

Each time an event occurs JS, potentially more than one event object representing it is generated on the python side as a result. I want to eliminate this behaviour

If I create a cache of event objects within Python, I can prevent the default behaviour that is auto-fabricating an event when one is received from Javascript by checking if one has already been cached for the JS counterpart

The problem with this approach is, when do I kill the pythonic copy?

If I don't, that dictionary just continues to grow. What I really need is an OnDeallocate method to fire on the object when it's garbage collected in Javascript, to signal to python to do the same

Django Question. I'm trying to query the db to get the pk of the current object. I have this:

'pk'

Side note. The following variation produces the same error:

query_article_object = get_object_or_404(Article, id=self.kwargs['pk'])```

Did that, but all i'm getting is /html/body

[patent glade]

For some reason I'm having a terrible time explaining why I need this this, but, I need a way to detect when an event has finished propagating

Some sort of an 'OnComplete' method on event class

Sorry, this is in Javascript

Any thoughts?

[inland oak]

I know that those events are accessable from chrome extensions at least

when you connect to chrome API

it is actually even named in exactly same way I think 😉

https://developer.chrome.com/docs/extensions/reference/
https://developer.chrome.com/docs/extensions/reference/tabs/
onUpdated it is actually, where it is possible to recieve status complete

perhaps it could of some help

oh!

as example of chrome extension

they provide the next javascript code

document.addEventListener('DOMContentLoaded', function() {

 // here I attach my listeners

}

this could be used perhaps without chrome API, it should be available just in JS I think

besides DOMContentLoaded perhaps there other events you can attach yourself to
