Hello, i have one question when i am doing python manage.py makemigrations but django doesn't create all the fields for the Todo Model, please help what's wrong here?

class Todo(models.Model): task = models.CharField(max_length=255) title = models.CharField(max_length=100), _date = models.CharField(max_length=100), categories = models.CharField(max_length=100), keywords = models.CharField(max_length=100), summary = models.TextField(), description = models.TextField()

Migration Model

`class Migration(migrations.Migration):

initial = True

dependencies = [
]

operations = [
    migrations.CreateModel(
        name='Todo',
        fields=[
            ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
            ('task', models.CharField(max_length=255)),
            ('description', models.TextField()),
        ],
    ),
]`

[wicked elbow]

your missing a comma after task = models.CharField(max_length=255)

id also suggest using a models.DateTimeField(auto_now_add=True) for the date. itll be standardized that way

[toxic forge]

@wicked elbow i did both but output is like below now

class Todo(models.Model): task = models.CharField(max_length=255), title = models.CharField(max_length=100), _date = models.DateTimeField(auto_now_add=True), categories = models.CharField(max_length=100), keywords = models.CharField(max_length=100), summary = models.TextField(), description = models.TextField()

`class Migration(migrations.Migration):

initial = True

dependencies = [
]

operations = [
    migrations.CreateModel(
        name='Todo',
        fields=[
            ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
            ('description', models.TextField()),
        ],
    ),
]`

[wicked elbow]

open the actual db file. migrations dont show every field

[toxic forge]

@wicked elbow 0001_initial.py?

db i am using djongo

[wicked elbow]

no. your db file that was created, migration files dont show everything

[toxic forge]

oh but in /admin it only shows description field

[wicked elbow]

i dont see anything else wrong with it though.

[toxic forge]

django version can be the issue?

[wicked elbow]

im dumb, sorry still morning time. remove all the commas

[toxic forge]

@wicked elbow Thanks man small , issue it took me hours to figure it out 🙂

[wicked elbow]

lmao. my brain isnt working yet. i looked at your code and thought they were needed. not awake yet haha

[leaden widget]

how can I make 2 elements stand next to each other(horizontal) using css?

[toxic forge]

Thanks again for the help

[wicked elbow]

use a flex box

[wicked elbow]

np

[wicked elbow]

<div style="display: flex; flex-direction: row">
  <div>Column 1</div>
  <div>Column 2</div>
</div>

[leaden widget]

it worked, thank you !

[wicked elbow]

no worries

[native tide]

how do i make a custom error 404 page using django?

views .py

def handler404(request,exception):
   return render(request, 'rostats_app/error404.html', status=404)

urls .py

handler404 = 'rostats_app.views.handler404'

comes up with this

[toxic flame]

What does the debug=False say?

[wicked elbow]

you dont need one... django doesnt serve in production. so youd set that up on the server you use

[native tide]

yh

[native tide]

wait wdym?

[native tide]

also wdym lol

[wicked elbow]

django doesnt serve static files when debug=False. that includes the 404 page. your apache/nginx server will handle the error pages

django isnt a server. its backend coding. you'll have to set up mod-WSGI or ASGI to deply a django app

[native tide]

dude i dont get what you mean

[native tide]

when i go on any other page it works

[wicked elbow]

in your settings.py file, you have debug=True which means django is running in developement. if you turn debug=False itll run in production. but you have to also set up, apache with mod-wsgi or a nginx server with daphne/uvicorn/gunciorn

[dark hare]

debug=True will give them the full stack trace

nothing to do with serving static files

[native tide]

why would that matter when the other pages load

[native tide]

debug=True doesnt just return the errors?

[dark hare]

debug=true will return the stack trace in the browser

[native tide]

any ideas to help me

idk what im doing wrong

[wicked elbow]

yes, in developement django serves static. in production, django doesnt. thats how you switch from to developement to production.

[dark hare]

https://docs.djangoproject.com/en/3.1/ref/settings/#std:setting-DEBUG

[native tide]

is that for me?

[dark hare]

kendal, what do you mean serves static??

[wicked elbow]

https://stackoverflow.com/questions/5836674/why-does-debug-false-setting-make-my-django-static-files-access-fail

[native tide]

can anyone help me???

[native tide]

dude idk what you are on my files serve properly

just the error page doesnt work

which is probably because im doing something wrong

[wicked elbow]

404 is a static file... you cant make a custom one in django

[native tide]

what?

[wicked elbow]

your server will handle the 404. django isnt a server

[native tide]

dude you just confused me way more

[wicked elbow]

ive said the same thing multiple times

[native tide]

yea which is probably why you are confusing me since idk what you are on about

https://docs.djangoproject.com/en/3.1/ref/views/#django.views.defaults.page_not_found

[dark hare]

yes, by default apache or nginx etc should handle static files, but you can configure your django app to serve them

[native tide]

do you know how to fix my problem

[dark hare]

are you running your django app locally?

[native tide]

yea

[dark hare]

what is your debug setting value?

[native tide]

False

[dark hare]

why?

[native tide]

wdym why

[dark hare]

you need it to be true

[native tide]

no...

[wicked elbow]

then it needs to be running on a server.

[dark hare]

^

[dark hare]

did you not read what Kendal said?

[wicked elbow]

it wont serve anything when debug equals false without a server

[dark hare]

you cannot serve static files locally by default with debug=false

[native tide]

all the other views work tho...?

why would it be different from the 404 page

[wicked elbow]

throw it on stack exchange, or ask google. im not gonna beat a dead horse.

[native tide]

cool

[dark hare]

do you know your function is being called?

have you put a debugger in there and checked

[wicked elbow]

If you still need to server static locally (e.g. for testing without debug) you can run devserver in insecure mode:

manage.py runserver --insecure

but you really dont need to handle page errors in django. let the server do its job...

[wicked elbow]

for learning purposes, use django for your views/html. in the real world though, youll use django as an api backend. and you'll use react, angular, or vue to run your pages in the front end. thats true almost everywhere these days

[native tide]

k thx

[native tide]

no it doesnt

[wicked elbow]

did you try manage.py runserver --insecure itll still boot the server up with debug=False

but again, you dont want to bog python down with serving static even though theres ways to do it. thats the whole job of a server. IMO what they were built to do. python is slow, dont put to many tasks for it to do. handling 1000s of people accessing an api is more then enough.

[toxic flame]

He's not using static files anyways, he's using a template

Though they aren't very different, django does serve templates

[toxic flame]

Well shit lol hahahah, I've made alot of buisness django websites telling them it's secure ;-; lol

[static wind]

hey everyone, i'm having a lot of trouble setting up my flask application with namehero & cpanel
i've followed at least 10 different methods of setting it up, none of which have worked. a common error i seem to be getting is just a 503 service unavailable page, on any routes on the page, regardless of if i include them in flask
i'm using the python app option, and i've added a requirements.txt that has every package i need, although right now i'm just using the most basic flask thing to display a hello world

i'm frustrated and confused, any help would be appreciated

[wicked elbow]

its secure, but its not best practice. its similar to how php/asp is done or at least used to be done. havent messed with either in 10 years. theres just faster ways to do things.

[keen python]

I think HTML is the easiest programming language to make a website because I've made 5 or websites and the ones i used HTML was the easiest who agrees?

[noble spoke]

html is the only way to make a website

its the only thing rendered in a browser

[barren moth]

👀

actually I beg to differ

firefox pretty prints api outputs

with json

[toxic flame]

Yea welp i think i gotta include the "React fronted django backend instead lol"

[wicked elbow]

doesnt have to be react, can be vue or angular, or your own static javascript. most pages just arent static anymore.

[toxic flame]

yea react is just an example

react as in a fronted framework

[wicked elbow]

actually, your wrong. can build a complete website with just javascript. no html whatsoever.

[noble spoke]

a json output isnt exactly what you call a website

[wicked elbow]

yea, react is the most popular one.

[noble spoke]

and js creates html elements to place in the DOM, its not rendered

[toxic flame]

JSX IS THE NEW THING BOYS

[wicked elbow]

kinda yes, but HTML isnt the only thing rendered in a web page. javascript and css are both rendered as well.

[noble spoke]

javascript isnt rendered dude, theres a reason i used that word and not anything else

[wicked elbow]

lmao you've never used a framework, obviously. it uses html, but the jsx is rendered in javascript. any dom modification is rendered.

[toxic flame]

yop

[noble spoke]

https://reactjs.org/docs/jsx-in-depth.html

[static wind]

anyone know whats up

[wicked elbow]

<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <title>safespace</title>
    {% load static %}
    <link rel="stylesheet" href="{% static "frontend/stylesheet-main2.css"%}" />
</head>
<body>
    <div id="app" style="height: 100%; width: 100%"></div>

    <script src="{% static "frontend/main.js"%}"></script>
</body>
</html>

thats all the html in my entire website. the rest is jsx, react-dom
to say javascript doesnt render is completely wrong.

[toxic flame]

U got python module?

[static wind]

yea

3.7.8

[toxic flame]

I only have setup django on cpanel.but they shouldn't be much difference

So the python uses a passenger_wsgi.py to do everything for u

just find ur wsgi file and import the "application" or whatever u have set it to onto the passenger_wsgi.py

[static wind]

yeah i've read things saying to get rid of that

yeah

thats what im doing

503

[wicked elbow]

what server?

[static wind]

cpanel

[toxic flame]

hMMMMMmMM

[static wind]

flask

[toxic flame]

maybe like django u have to set allowed host?

[static wind]

hm?

[toxic flame]

Did u pip install the stuff

[static wind]

yes

[toxic flame]

And errors on the log?

[static wind]

no log file

no clue how that works

[toxic flame]

u should have one, its created by default

[static wind]

where

[toxic flame]

its on /logs for me

[static wind]

directory is empty

lemme add a filepath there and then restart

yea no logs

set it to logs/passenger.log which is the default or whatever

[toxic flame]

Yea

[static wind]

no logs

[wicked elbow]

https://docs.cpanel.net/knowledge-base/web-services/how-to-install-a-python-wsgi-application/ according to cpanel they dont fully support python wsgi applications

[toxic flame]

idk man, never set for production any flask apps

[static wind]

followed that

wait

if its running on localhost

[wicked elbow]

it probably has something to do with the wsgi set up though

[static wind]

yeah i have no clue though

ig rn its deployed on localhost or whatever

because i tried running thru terminal and it said it was running at 127.0.0.1:5000 which is localhost

[wicked elbow]

localhost is wrong on a shared server. cant run on 127.0.0.1/ should have a private ip for you to use

[static wind]

do you have any idea how to fix that

[wicked elbow]

im just guessing honestly, ive only set up in aws. and aws gives you a private ip to use

and only django

[static wind]

ok wait here's what i have setup for wsgi stuff if this helps at all

#main.py
from flask import Flask
app = Flask(__name__)


@app.route("/")
def hello():
    return "This is Hello World!\n", 200

if __name__ == "__main__":
    app.run()

#passenger_wsgi.py
from main import app as application

and then in the application manager:

[wicked elbow]

i dont know anything further to help with cPanel though, never used it

[toxic flame]

set startup file to passenger_wsgi.py @static wind

Django: Hello everyone, my question is about an update view but with multiple forms not one. So you would get through a filter call many objects that need to be put in the form?

[static wind]

ok will try that @toxic flame

[toxic flame]

lmk

[static wind]

503

[toxic flame]

• restart right?

[static wind]

yup

[toxic flame]

Gomenasai brother i got no more jam

[static wind]

damn

[native tide]

Django: Hello everyone, my question is about an update view but with multiple forms not one. So you would get through a filter call many objects that need to be put in the form?

Please help

[wooden ruin]

you would likely set the action of each form to different URLS, to handle it easier and make it organized.

[native tide]

I understand but they can all be updated at the same time

so need to be displayed on one page

[wicked elbow]

what your talking about would require JavaScript im pretty sure. im confused about why everything is seperate if it needs to be done together

[glossy arrow]

Say I have something like ```py
@app.route("/")
def index(request):
response = TextResponse("Hi")
session.init_session(response)
return response

@app.route("/get")
def get(request):
return TextResponse(session(request)["data"])
``` The session.init_session() method is setting a cookie, but its only available on the next request

How can I make it available on the same request?

[toxic flame]

run the function seperately i guess

or again twice

[glossy arrow]

Hm

I think I've figured it out

[toxic flame]

I am django user i have no idea lul

[glossy arrow]

Lol

BTW, is this a correct implementation of a Session? ```py
class SessionHandler:
def init(self, app, secret_key=None):
self.app = app
self.lifetime = self.app.to_seconds(1, "hour")

    self.secret_key = secrets.token_urlsafe()

    self._dict = {}

    self.initialized = False

def init_session(self, request, response):
    if not request.cookies.get("secret_key"):
        key = secrets.token_urlsafe(50)
        response.set_cookie("secret_key", key+self.secret_key,
                            httponly=True, max_age=self.lifetime)

        self._dict[key] = {}

        self.initialized = True

    self.initialized = True

def __call__(self, request):
    assert self.initialized, "Session Not Initialized"
    return self._dict[request.cookies.get("secret_key")]

[wicked elbow]

no idea, i just use basic setup

[native tide]

hey

im having an issue fitting an image to fit the whole screen

https://guilded.dev/

ive tried setting max-height and height to 100%

but cant figure anything out

[hybrid bobcat]

can Flask model store custom object in columns?
so like if i have db.Column(db.string(20)) can i replace string with a custom object?

[desert parrot]

Hey. I have a large amount of html code in an url. Is there any quick way of reading it all? requests and urllib.request are taking so long.

[limber dew]

i dont know if this is a right channel to post my problem.
My question is how can i pass the variable from Vue js to django?

<div v-for="post in posts" class="post-preview">
          <a href="{%url 'detail' [[post.id]]%}">

This is not working, any ideas to tell me a different approach ?

[wicked elbow]

called querystrings. www.somepage.com/?variable_name=value

[marble spade]

<form method="POST" action="">
        {% csrf_token %}
        {{form.username.label}}
        {{form.username}}

        {{form.email.label}}
        {{form.email}}

        {{form.password1.label}}
        {{form.password1}}

        {{form.password2.label}}
        {{form.password2}}

        <input class="submit" type="submit" name="UserCreate">
    </form>

I have the following form class in Django however I want to style it in CSS. I want to style the input boxes (The form bit as it is a built in input box). I have tried to create div classes to no avail!

Any help would be greatly appreciated.

[wicked elbow]

people need to get away from using django as a whole package distributor. its just not though. build html and connect it to your backend.

[marble spade]

what if your just trying to get into web dev

[wicked elbow]

dont start with django, start with html/css/js. then learn your backend and connect it to your front end.

you can't have a good back end without a quality front end template

but fyi you can do @marble spade

<style>
.something * {
  ...styles for the stuff inside something
}
or
.something input {
  ... styles for your input here
}
</style>
<div classname="something">
  {{form.email.label}}
  {{form.email}}
</div>

[marble spade]

is there any way for me to put text inside of the input class, like a placeholder I believe it is called/

[wicked elbow]

no idea how to do it from django, but in pure html <input type='text' placeholder='Text_goes_here' />

[marble spade]

yeah hm doesn't really work with django

[limber dew]

What do you mean by that, if i put an integer it works otherwise its raising an error
Could not parse the remainder: '[[post.id]]' from '[[post.id]]'

[vestal hound]

okay

so how it worked was

channels would provide a compatibility layer

to run your Django project as ASGI

but Django itself

was only WSGI compatible

now Django is natively ASGI compatible

[wicked elbow]

pass as a querystring, then you can use .request.query_params.get(''variable_name", default=None) in django to get your data

[vestal hound]

so at that point the middleware, views etc. HAD to run synchronously

[wicked elbow]

im still pretty sure ASGI support has been around for a bit. channels v2 was had daphne which was an asgi server to run on

and channels v2 compared to v1 was a huge leap forward was what the video i watched said

so i would think for sure true asgi has been supported since then

[vestal hound]

https://docs.djangoproject.com/en/3.1/releases/3.0/#asgi-support

[wicked elbow]

been around since dec 2019, so im taking it your more correct then i thought. makes more sense the stuff about the sync_to_async commands in channels

[vestal hound]

yes

[vestal hound]

so did v1

but if Django supported ASGI natively

you wouldn’t even have needed daphne

[wicked elbow]

you still have to deploy on an asgi server. thats what daphne and uvicorn are. havent found asgi support for apache

[vestal hound]

ye but at that time

[wicked elbow]

i wanna know why channels isnt built into django. websockets are every day things

[vestal hound]

uvicorn did not exist

they HAD to make daphne to support ASGI at all

[vestal hound]

because Django is old

and it takes a lot of effort to make it async without breaking stuff

and to be fair many apps can run without websockets

or any sort of server to client communication, for that matter

[wicked elbow]

daphne is maintained by the same person who maintains channels, but hes said uvicorn is more advanced then daphne these days

[vestal hound]

yes

precisely my point

daphne was made FOR channels because there was no ASGI server and one was necessary for Django integration

[wicked elbow]

a lot of modern apps use sockets, video calls, all the social media sites, any delivery service with real time tracking. and chat. web sockets arent exactly new. was supported in browsers in 2009

im just saying, i find it weird that theres no major documentation behind using it with a database behind it. most things i see use redis to pass the next message to all active users, but doesnt do anything with data that happened before you joined. it makes it difficult to program, no documentation with no user base to explain. just kinda trial and error until i figure it out

and even channels doesnt have true support with rest framework. have to use another 3rd party module to get it to work.

i bought a django book to help me understand the more advanced topics of all the different views/viewsets/generics and i feel like i wasted my money. just feels like maybe using django was a bad idea cause of the limited support. and when i talk web sockets it goes over everyones heads

i did finally find a couple different examples of channels with drf now. studying how they are done

[vestal hound]

there are bugs

in Django

that are LITERALLY

10 years old

many parts of Django are really outdated

lacking websocket support is defo one of them

when you get affected by the others you'll know

but yeah.

like I have legitimately considered

starting from the ground up

with FastAPI + Peewee

[wicked elbow]

yea, its just amazing to me though. django could be something. i like it way more then i did php. but theres some major hurdles in it. lot of people enjoy using it. but like a lot of other things python related, it has pitfalls. just like guis like tkinter

[vestal hound]

Tkinter is also really old

well

a lot of people use Django

therefore backward compatibility is very important

therefore lower agility

[wicked elbow]

yes i know, but still. gotta be modern to stay in use

[still wedge]

yo

ok

ok

is id selector

. is class selector

try with .Logo

noice

🙂

np

you can dm if youll need more help, we can google it together 🙂

[toxic flame]

@vestal hound what backend framework do u recommend at these modern days?

[still wedge]

how does django compare to CakePHP?

[indigo kettle]

django is not user friendly?

3x is a lot

I think django is pretty good

[still wedge]

to me only speed matters...

[indigo kettle]

so to say something is 3x more user friendly than django is pretty crazy

[still wedge]

speed as in speed of web app, not amphetamines

🙂

anyway... how is your css going? is this your first time doing front end? i can recommend you some resources i used to learn design

lol wtf

2 oranges

not again

its you... ok...

only on the web...

anyway...

about css

as i said, i could recommend you some yt channels i found most useful to kickstart learning css

css can be... finicky...

i know lol

[indigo kettle]

why is this happening

lmao

[still wedge]

im checking each message now

for sender id

XD

we have 2 oranges

whats with deleting messages?

[wicked elbow]

something else that blows my mind, Pycharm Pro doesnt have full django support. still get warnings for things that are common place in django in the IDE

[split steeple]

Yeah that’s kind of annoying. Everything looks right on the views page but there’s an orange blip on the right telling me a variable doesn’t belong

[wicked elbow]

drives me nuts... i mean IDEs are only so smart, but like the Model.objects.all() they need to fix that one. super annoying

[split steeple]

Yes. They do.

Good lord.

[toxic flame]

just use vim and all your problems will be gone

• productivity

• no syntax warnings

• no need for the mouse

[buoyant shuttle]

anyone here

i have a problem running a script in the same file as models.py meaning inside my app. but getting this error

 File "/home/samuel/dev/tools/stocks-scraping/reddit_stocks_scraper/reddit/reddit.py", line 12, in <module>
    from .models import ScrapedStocksStatisticDB
ImportError: attempted relative import with no known parent package

[wicked elbow]

cant beat pycharm/web storm in terms of productivity

[toxic flame]

idk about that

No mouse usage = 20% time save

[noble spoke]

Does your app have an __init__.py

[native root]

RE: Your help channel earlier. The error you were getting with object is you passing arguments all the way down to object.__init__. IT'd be the same as calling object(1) -- the object constructor only takes on argument: self.

#help-corn (so I can jump )

[wicked elbow]

found out, it was because my redis server wasnt initiated, that was actually never an error, just user error

[native root]

F

[wicked elbow]

but i am still getting a call error, im just trying to find the issue, but thanks for seeing that

[native root]

Yeah, looking into it atm

This seems a problem line.. I'm tired but

  File "H:\Users\Kendal\Desktop\safespace\safespace\notification_api\consumers.py", line 77, in subscribe_to_list
    await self.notify_change_handler(list=True)

What's the code involved here?

[wicked elbow]

yea, its passing to the wrong notify_change_handler. i dont understand why theres 4 of them anyways
should pass to

    @notify_change_handler.groups_for_consumer
    def notify_change_handler(self, owner=None, list=False, **kwargs):
        # This is called when you subscribe/unsubscribe
        if owner is not None:
            yield f'-owner-#{owner}'
        if list:
            yield '-all'
``` but its passing to 
```py
    @model_observer(Notifications)
    async def notify_change_handler(self, message, observer=None, **kwargs):
        # called when a subscribed item changes
        await self.send_json(message)

as far as i can tell.

[native root]

Well, are they in different classes or have you defined two methods with the same name?

[wicked elbow]

they are all in the same class, the decorators have something to do with where they are supposed to go. the code i followed and anothers example does the exact same thing

[native root]

Ok.

well, don't do that

It's a bad example. Because you're using decorators I'd give it a shot giving them unique names and trying to call it specifically. In python the last one defined is the one that ends up with the name, so perhaps you've got the order different.

[wicked elbow]

actually, it was my error. i missed await self.notify_change_handler.subscribe(list=True)

[dawn heath]

machine learning via tittle or summary for rss?

[wicked elbow]

yea, its more advanced code them ive seen honestly. seems odd to me to do it that way too, but that one word solved it. got an error with json encoding, but im pretty sure thats my bad as well

[native root]

Yeah, would imply you gave it stuff that wasn't just dict/list/str/int/float

It's a bit strange and boilerplatey but if you familiarize yourself with djangos save signals it actually kinda makes some sense

Basically I think send_json calls json.dumps() on what' it's givne, you're giving it message, and in the examples message is usally a dict/jsonlike structure, so you've probably given it an object somewhere

[wicked elbow]

yea, it had to do with my last line. i need to push the instance through my serializer. on return. instead of trying to manually setting it

[cosmic panther]

if youre writing a super simple landing page thats going to take a users information before directing them to a youtube video. Is it best to store that info in a databse or something more simple like a googel doc

[wicked elbow]

yea, thats exactly what it has to deal with, it cant get the foreignkey data

and i solved that as well, had to call the child of the foreignkey. thanks @native root and @manic frost. i have real time notifications now!

[lavish prism]

Hey @tough tartan!

It looks like you tried to attach a Python file - please use a code-pasting service such as https://paste.pythondiscord.com

[native root]

[tough tartan]

https://paste.pythondiscord.com/qikexijapi.py
Does anyone see what the problem is?

[wicked elbow]

looks like your passing the wrong client id, but i cant tell, i dont know flask even in the slightest

[native root]

^

[tough tartan]

@wicked elbow what would the correct token be?

[wicked elbow]

is that your client id?

you should probably not be making that public.

[tough tartan]

yes

[wicked elbow]

are you sure its correct?

[eternal blade]

This is how I load it in the html

{% load static %}
<link rel="stylesheet" type="text/css" href="{% static 'css\style.css' %}">```And when I enter the homepage this is what I see in the terminal
```powershell
[03/Mar/2021 09:40:14] "GET /static/css/style.css HTTP/1.1" 404 1766```I have set a static url and a static root in the settings.py, Thanks :)

Btw sorry for the late response I didn't see your message ping me next time when you reply

[nocturne remnant]

I'm trying to set up a socket.io function that emits a message every 10 seconds using Flask (or Django), I already got it semi-working with Threads but it was spawning multiple threads so there must be a better way, I already explored Celery (not good for this use case) and I'm looking at Eventlet or Gevent.

[tough tartan]

I will check

[tough tartan]

if it is, what would the problem be?

[gritty sky]

can anyone help me with some bs4 stuff lol

[nocturne remnant]

@gritty sky what are u scraping

[gritty sky]

chegg site

im not v familiar w bs4, so i found some open source for it

but it keeps retuning there is not text etc

[tough tartan]

https://paste.pythondiscord.com/qikexijapi.py
Does anyone see what the problem is?
Please PM me.

[nocturne remnant]

paste the line of code

[gritty sky]

https://paste.pythondiscord.com/lecoquduho.py

its there

unless its something wrong with my headers?

[nocturne remnant]

which line returns the error

[gritty sky]

sorry, i meant to say it doesnt return nothing

it sends back whats on line 40

[wicked elbow]

that was my only guess sorry

[nocturne remnant]

@gritty sky it could be anything. hard to say, you should add print statements to debug

[gritty sky]

hmm alright i will, ty

[nocturne remnant]

@gritty sky i mean since you wrapped the whole function in a try: statement

[spare iris]

@gritty sky is scraping against their TOS?

[nocturne remnant]

@gritty sky it fails somewhere inside the try:

[gritty sky]

no clue tbh, but i have seen discord chegg bots

[gritty sky]

yeah. alriht ill do that, ty!

[spare iris]

@gritty sky uhhhh I would check that out you can get in serious trouble

[nocturne remnant]

@gritty sky like make sure line 18 works

[gritty sky]

gotchu

[gritty sky]

eh

[nocturne remnant]

@spare iris serious trouble? Lol how

They're gonna call the feds because he screen scraped their public website? lmfao

[gritty sky]

[spare iris]

@nocturne remnant get sued lmao

do whatever you want lmao I said what I normally say about webscraping

[gritty sky]

that one is fine

[nocturne remnant]

@gritty sky remove the try/except statement and run it

@spare iris what do you think about using cookies to mine cryptocurrency in the user's browser?

[spare iris]

@nocturne remnant Idk dude I’m just trying to sleep

[nocturne remnant]

maybe turn off your computer then

[gritty sky]

@nocturne remnant

[nocturne remnant]

@gritty sky then the problem is on line 20

@gritty sky put print(type(answerDiv))

@gritty sky try changing getText() to get_text()

[gritty sky]

bet, i gotta head to sleep but i’ll try tmro fs

ty bro :)

[nocturne remnant]

@gritty sky you're using bs3 methods

[gritty sky]

ohhh

damn

welp

[nocturne remnant]

yeah try changing that tomorrow

[gritty sky]

will do, ty

[loud elbow]

hey

so um how do I change the symbol of this when working on a local file

[eternal blade]

Hi, I have a css file linked to a html file, when I look at the console I can see a request been sent to the css file but the response status is 404.
This is how I connect the css file to the html```py
{% load static %}
<link rel="stylesheet" type="text/css" href="{% static 'css\style.css' %}">

This is what I see in the terminal```cmd
[03/Mar/2021 11:46:20] "GET / HTTP/1.1" 200 3985
[03/Mar/2021 11:46:20] "GET /static/css/style.css HTTP/1.1" 404 1766```
This is my settings.py```py
STATIC_URL = '/static/'
STATIC_ROOT = "static"

Thanks :)

[inland copper]

do u get something like a no found favico? @eternal blade

[inland copper]

u change the title tag

and add an img src

[eternal blade]

No

[inland copper]

hmmm

can u give a screenshot of your css file?

also this is not needed for css

just do {% include 'path' %}

[eternal blade]

This is what I see in the terminal

[03/Mar/2021 11:56:35] "GET / HTTP/1.1" 200 3985
[03/Mar/2021 11:56:35] "GET /static/css/style.css HTTP/1.1" 404 1766
[03/Mar/2021 11:56:35] "GET / HTTP/1.1" 200 3985
[03/Mar/2021 11:56:36] "GET /static/css/style.css HTTP/1.1" 404 1766```

[inland copper]

then the styling will work

[eternal blade]

so the path of the css file?

[inland copper]

do {% include 'static/css/style.css' %}

[eternal blade]

Ok, thanks I'll try that

[inland copper]

no

sorry

u don't do it in the link rel

do it in the body

tag

@eternal blade

[eternal blade]

I know that I shouldn't do it but the css still needs to load right?.

[inland copper]

yes

that's the point

show me your css file

[eternal blade]

Ya, I'll change it cuz what i am doing now is a bad practice

[inland copper]

u just have font-family, alignment etc?

[inland copper]

ik

but it'll wor

[eternal blade]

yes

[inland copper]

k

try and say if it is working

[eternal blade]

Ok

[inland copper]

is it working? @eternal blade

[eternal blade]

Now it is not sending any request

[03/Mar/2021 12:02:25] "GET / HTTP/1.1" 200 3964

[inland copper]

what?

but is the styling working?

did u do python manage.py collectstatic?

in the cmd/terminal

that might be one reason the static isn't working

[eternal blade]

Now I can see this

[03/Mar/2021 12:04:47] "GET / HTTP/1.1" 200 3985
Not Found: /h1{    color: red;}
[03/Mar/2021 12:04:47] "GET /h1%7B%20%20%20%20color:%20red;%7D HTTP/1.1" 404 2991```

[inland copper]

u have an an error in the css file

but it is successfuly loading the css alright

[eternal blade]

I just added ```css
h1{
color: red;
}

[eternal blade]

No

[inland copper]

did u do python manage.py collectstatic?

?

that is important

[eternal blade]

I did it, wait ill do it again

[inland copper]

and also show me the output

type yes if it asks a question

[eternal blade]

Type 'yes' to continue, or 'no' to cancel: yes 

0 static files copied to 'D:\projects\app\static', 132 unmodified.```

it didnt copy anything

I ran this command before also

[inland copper]

hmmm

i made a website on these static files

but i can't figure the prob

https://rkkcloud.herokuapp.com

[eternal blade]

Nice

[inland copper]

hope it helps

u can catch a step u missed maybe

[eternal blade]

Thanks I'll check it

[inland copper]

STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)

put this in settings.py

if u didn't already @eternal blade

[eternal blade]

Ok, ill put it thanks

after that do i need to run the collectstatic command?

[inland copper]

yes

i am not sure if it will work

but it was recomended in a website

[eternal blade]

?: (staticfiles.E002) The STATICFILES_DIRS setting should not contain the STATIC_ROOT setting.```

[inland copper]

why is your static_root and static url the same? @eternal blade

[eternal blade]

Looks like I cannot have the same setting for those two

[inland copper]

both are same

in your settings.py

u shld create a new folder called static_cdn and that shld be your root

[eternal blade]

I didnt know that i cant have the same thing
wait ill change it

[inland copper]

STATIC_ROOT = os.path.join(BASE_DIR, 'static_cdn')

Does aiohttp not create an OPTIONS route for each POST route? That seems quite silly to me

[opaque rivet]

would that lead to most requests being blocked by CORS?

[manic frost]

yeah, that's why I'm asking 😄

[opaque rivet]

hmm, been trying to read about it and came across this:

https://stackoverflow.com/questions/41679725/preflight-request-is-sent-with-all-methods

you could try to set a custom header, or change your Content-Type header to something other than listed, maybe this will help

[manic frost]

well, that's quite a hack

maybe I should open an issue on aiohttp

because I don't really want to add an OPTION for every post

[opaque rivet]

sure, but it looks like it's more due to the specification of cors:
https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#simple_requests

[manic frost]

Maybe I should just give up and use starlette/fastapi

[opaque rivet]

does your CORS block every request which doesn't have a preflight?

[opaque rivet]

you need to deserialize JSON into a python dictionary, look into DRF for some serializing / de-serializing (always forget which is the right term)

[manic frost]

No, 'simple' requests work fine (i.e. without preflights). A request with preflight (basically, every POST with a JSON body...) fails

[vestal hound]

indeed

[opaque rivet]

i see, could it be that your POST is still seen as a "simple request" by the docs, so isn't triggering a preflight?
so I guess you're looking for other libs that auto send a preflight for POSTs

[manic frost]

I can't choose whether I'm making a preflight request because the browser is making it.

ah I see, aiohttp-cors actually adds the OPTIONS routes https://github.com/aio-libs/aiohttp-cors#cross-origin-resource-sharing, so I'll need to use it.

I don't really need CORS (because the frontend will be statically served from the same host), it's just for local testing, so that I can restart the frontend and the backend independently

[opaque rivet]

i see, something new learnt every day 🙂

[ornate burrow]

what is your guys opinions on optimal resolution/filesize for images on a website?

i have some pretty large files (all are approx 5-10mb each) and my cms wont even allow that size to be uploaded

[desert parrot]

okay I have a webpage. On the webpage, there is a clickable. If I click it, it downloads a file. Is there a way to download that file using a python script?

[ornate burrow]

wouldnt a get request work?

import requests

print('Beginning file download with requests')

url = 'http://i3.ytimg.com/vi/J---aiyznGQ/mqdefault.jpg'
r = requests.get(url)

with open('/Users/scott/Downloads/cat3.jpg', 'wb') as f:
    f.write(r.content)

# Retrieve HTTP meta-data
print(r.status_code)
print(r.headers['content-type'])
print(r.encoding)

[native tide]

hey, can someone give me some feedback on the website im making?

import time
import random

while True:
    sites = random.choice(['google.com', 'youtube.com', 'weather.gov'])
    visit = "http://{}".format(sites)
    webbrowser.open(visit)
    seconds = random.randrange(1, 5)
    time.sleep(seconds)
``` It gives me error:  File "c:\Users\burka\OneDrive\Dokumenti\python coding\coding\webbrowser.py", line 7, in <module>       
    webbrowser.open(visit)
AttributeError: partially initialized module 'webbrowser' has no attribute 'open' (most likely due to a circular import)

webbrowser

is that the name of your file?

thats running from?

so your trying to import webbrowser from a file called webbrowser, See the issue there?

@native tide

ohhhh

I see

[desert parrot]

Hey.

how can I get the value of a driver.find_element?

[native tide]

Yeh thanks

[desert parrot]

Like I want that

[native tide]

you need to find class

your using selenium or bs4? @desert parrot

[desert parrot]

selenium

[native tide]

driver.find_element_by_class

I think it should be like that

@desert parrot https://selenium-python.readthedocs.io/locating-elements.html

[desert parrot]

I figured it
Its driver.find_element().text

[native tide]

ooo

[tropic mason]

hi, do you still need feedback? 🙂

[native tide]

yea

@tropic mason

its https://guilded.dev

its not got much rn

but looking for feedback before i finish it

[tropic mason]

so far so good 🙂 i think you can reduce the indentation by 50%

still looking good imo

do you want feedback on the code as well or just the visuals?

[manic frost]

@native tide Not much content, I suppose, but you should increase the font size. It's a bit hard to see, and certainly hard to click on the links.

Also, the website doesn't look well on mobile

The colors are good.

You should look into media queries and CSS Grid:

[native tide]

Hey guys, can I ask a javascript question?

There is something confusing me

Iwas working with the javascript onedrive sdk, and felt curious to check out the library and see how something works https://js.live.net/v7.2/OneDrive.js
I beautified a bit and this is how it starts:

none of this makes any sense to me, is this some kind of boilerplate or something, cause I can't understand any of it and its purpose. However my main question wan't about this, but I was curious of how this stuff works.

My main question, and the reason I was trying to read the library was to see how its executing code after clicking a button in the popup in the main browser window

thats how they suggested we use the library, this will open a onedrive popup. If I select a file and click Open the function given to success is executed in the main window. I was wondering how this "sorcery" happens, same goes for cancel and I guess if an error occurs, the error function is executed

[rotund harness]

In javascript you can use a function as an object's attribute so when you pass the options object to the OneDrive.open() function your function is passed with it. The .open function can then call this function so this is how OneDrive executes your function

[native tide]

but how does it do it from a button in a popup window

[tropic mason]

const OneDrive = {
    open: function (options) {
        // do things
        files = [] // get the files or idk
        options.success(files)
    }
}

does it help a little to understand what's going on behind the scences?

you pass your defined functions as options and then they will call those functions whenever it is needed

[rotund harness]

Somewhere in the OneDrive code it may be called like this:

'options.success()'

[tropic mason]

e.g. they will attach to their cancel button an event listener on click 🙂

[tropic mason]

they are going to provide the necessary args but, yes. 🙂

[native tide]

right,

when I click this

which is that function above

this opens

if I select it and click open

so thats where you are saying its calling options.success(files)

[tropic mason]

exactly

[native tide]

but how is it getting the files

[rotund harness]

Pretty much yeah

[native tide]

from the popup

[tropic mason]

probably via onedrive api

none of our business that's why you are using their code, i guess

[native tide]

yeah I know

[tropic mason]

if you open up the developer tools and check the network requests it should send a few GET requests to the OneDrive API 🙂

[native tide]

ehh, forget onedrive, lets say I want to open a popup

[tropic mason]

which then sends back file files

[native tide]

lets say there is a textbox and a button in the popup

if I wanted to get that text from the textbox in the popup when I click that button to my main window

how would I do it

[rotund harness]

What do you mean by popup?

The file selector?

[native tide]

yeah

[rotund harness]

What kind of text are you getting from there?

[native tide]

just an input type text

lets say

[rotund harness]

You can usually get text from an input through its id or class like this:

[native tide]

even if its in a different window?

[rotund harness]

I'm not sure tbh

text = document.getElementById("input-text").value;

This would work if it's in the same window

[native tide]

like lets say I have a window.open somewhere and instead of google.com I had a a page of my own that has an input field and button

[rotund harness]

I can't think of any easy ways to do that

I'm sure they exist though

[native tide]

ahh

[rotund harness]

Actually nvm

I think there might be a way

You do: new_window = window.open("https://google.com","test","height=400,width=400")And then in the windowwindow.returnValue = document.getElementById("input-text").value;Then do ```
text = new_window.returnValue;

I gtg

Good luck

hello guys ..
jQuery function is not woking after appending checkbox

[umbral bobcat]

Hey everyone, I've been working through Corey Schafer's flask tutorial on youtube recently. Amazing series of tutorials. Got to the video on Blueprints, and i feel like io have no idea what is going on now. Is it common practice to develop an application, then split all the different parts of once it is finished? All the finding unused modules and making sure each file has the correct modules imported has just totally knocked my confidence after thinking i was getting on quite well with the course. I just tried to create a small app from scratch, I have no idea where to start after watching this video

[native tide]

ahh thanks

[tough tartan]

https://paste.pythondiscord.com/qikexijapi.py
Does anyone see what the problem is?
Please PM me.

[cosmic panther]

I need to set up about 30 static web pages using django. All with seperate Domain names. All they are doing is hosting an embedded youtube video and a database that will collect infomation such as name and phone number. Whats the cheapest way for me to host all these sites together? Its for my sales team

[toxic flame]

use one vps or dedi and install cpanel with django

or nginx setup multiple ports for different django instances

but since it's static I don't see the need of using django, since django is practically a backend

Unless you can have 1 backend / main domain that rotates the video url per request and have all your web pages point to that

[native tide]

ok um

i need help with php on nginx

instead of loading the php it just ignores it and downloads it

any ideas?

[toxic flame]

[dark hare]

Thats great you're building an app from scratch! However dont be afraid to make mistakes, even though you might be building something you want to complete dont be afraid to rewrite or throw away bits you aren't happy with, this is learning and practicing, any other vocation requires practice and this is how you can practice. There is no right or wrong way of how to build an app, there are only techniques, but right now get stuck in and focus on what you want to build.

[burnt charm]

which should i learn?

Flask/dijango?

which is better/easier

?

[spare iris]

I used Flask

but whatever you want to do

[copper juniper]

Django is the the worst thing on earth, flask is cool to play with but it has very limited potential

[dapper tusk]

django isn't bad

[copper juniper]

Deploying both is a nightmare when compared to other frameworks

[dapper tusk]

that is true

[copper juniper]

Django is terrible

[dapper tusk]

instagram does quite fine using it

can't be too horrible

[copper juniper]

I mean unintuitive

[burnt charm]

guys!

[spare iris]

there will always be an opinion that will disagree w what you think

[dapper tusk]

ye, it does have a learning curve

[burnt charm]

im getting mixed signals here

[dapper tusk]

learn django, it is easy to get things done in and requires less setup than flask

[copper juniper]

Every time i need to do something with Django I know I will forget that and will have to read the docs again

[burnt charm]

flask or django?

ok listen

which is easier to learn and use?

[dapper tusk]

flask, but it is not as powerful

well, by default

[copper juniper]

Try both

[burnt charm]

which has more potential

[dapper tusk]

once you do actually set it up to do everything django comes with, its even worse than django since you have 4 different docs instead of 1 set of docs

Django I would say

a modern website would probably just use fastAPI with react.js though

[burnt charm]

which do i use then?

[dapper tusk]

honestly, for 99% of websites

[burnt charm]

im not looking to make a massive website

[dapper tusk]

either will work fine

toss a coin

[burnt charm]

do you guys know any websites made from flask?

[dapper tusk]

I think some of discords APIs are/were in flask

[burnt charm]

so that i can see what is truly possible to achieve with flask

[copper juniper]

Tbh if you are seroius about webdev you should just learn react/nodejs, all the hype and bling is there currently

[burnt charm]

nah python is my choice

[copper juniper]

Flask is minimalistic and you have to write your own plugins and modules, any react dev will do in an hour the things that you will do on your own in flask for long long days, hard to compete with that

[dapper tusk]

react doesn't really do backend

which is where flask shines

[copper juniper]

True

[dapper tusk]

I do agree react > jinja templates

[burnt charm]

so django?

0=0

[copper juniper]

Maybe react / flask woudl be a cool thing, but didn't tried that

[burnt charm]

;-;

[copper juniper]

I mean react flask combo

[dapper tusk]

essentially, there are 2 parts to webdev

[burnt charm]

)-(

[dapper tusk]

making the frontend, and the backend

the frontend is much easier in JS than in anything else right now

[burnt charm]

ok

[dapper tusk]

be it with vue.js, react or the "new cool framework"

[burnt charm]

and backend?

[dapper tusk]

the backend can be flask or django

and both will do about the same job

[burnt charm]

The questions is..... which one

[dapper tusk]

I suggest django since its less effort to setup

don't have to install a separate ORM and such

[burnt charm]

@dapper tusk @copper juniper have you both tried both django and flask?

[dapper tusk]

yes

[copper juniper]

Yupp

[burnt charm]

ok that means then both your opinoins are valid

@copper juniper what do you suggest?

[copper juniper]

My question is what do you want to do because python is not the strongest webdev language, not the best to learn as first

[dapper tusk]

python is perfectly fine for backend

node isn't that excellent

[copper juniper]

You can simply learn js, do react apps with simple backend on nodejs and be fine with that

[dapper tusk]

and honestly, node is a lot more effort to setup than django

[burnt charm]

a simple website, 3 pages max, some buttons you can click, fill out some login details, display info, cool pics

[copper juniper]

Yeah, but node can ie execute code in browser while python has to send it through some v8 interpreter I guess

And thats why its much slower this way

[dapper tusk]

we are talking about backend

you aren't running your logic in the browser

thats just stupid

[copper juniper]

Depends

[dapper tusk]

you are running it on the server

which you buy

[copper juniper]

I do appreciate the puppeteer framework on node

To do any webscraping is much better than anything in python afaik

[burnt charm]

OK. Django is the way to go for backend?

and frontend?

[dapper tusk]

lets just say yes for simplicity

for frontend you want react or vue.js, or just html+css+templates

pyppeteer does exist and is afaik very similar

[copper juniper]

@burnt charm How good are you with sql/nosql?

[dapper tusk]

the django ORM works with sql, and you don't really need to know sql for it

[copper juniper]

On flask you will have to do all hard db work from scratch

[dapper tusk]

you can use sqlalchemy to also get an ORM

[burnt charm]

beginner level, i could learn more

[copper juniper]

I think sqlalchemy is prettybad tbh, it is like learnng something completely different than sql and overloading your brain with this garbage methods

[burnt charm]

Guys, my main goal is to make a website with front end and backend by learning s least languages as possible.

[copper juniper]

Than go js, react frontend + nodejs backend, one language to do all

Won't be powerful but still can be decent

This is why js thrives right now

Not ideal, but fast to learn and make things

[quick cargo]

id probably recommend using TS over JS tbf

stops alot of easy and hard to debug errors at times

[copper juniper]

TS is compiled to the plain JS in the end anyway, transistion from one to another is pretty nice

Pretty ez to learn both

[quick cargo]

its just having those enforcements make TS nicer to work with as you're not running into underdefined all the time

[copper juniper]

Static typing alone removes half of security bugs on the planet so I guess TS will be the new standard someday

But to start today you can do both and will be fine

[polar nova]

is there anyone who use google app engine?

i am stuck with the sql database

it says attempted to write readonly database

is there anyone who faced with same problem?

[native tide]

can someone explain to me what reverse() does in django

[umbral bobcat]

Cheers for that! Yeah I get what you're saying, I think it's more the structure of the app that is confusing hell out of me now. I've looked at the flask mega tutorial as well which seems to structure things in a completely different way. So no I'm getting mixed up with the two different ways, and have files and imports all over the place.

[hard umbra]

It gets the URL of a view object.

[hard umbra]

Usually when a request comes in the URL of the request gets to be translated to a view.

[hard umbra]

If you already have the object in your business logic and need to create a link in your view, reverse() will get you the URL for the link.

Or it could just be the URL of a view without referencing a database object.

Sorry, fixed the above comment. URL gets translated to a view (either with or without parameters)

[native tide]

So it grabs the url the view is linked to?

why is it called reverse()

[hard umbra]

If you pass the view to the reverse function, yes.

because it is the reverse of the URL resolver process, I guess.

I think if you use the %url% in templates, it also triggers reverse.

[native tide]

ohhh I see

That makes sense thanks

[hard umbra]

You are welcome

[shadow gate]

Hi. Does anyone know how a celery task can continue after reboot? Or link to any resources/diagrams to help understand how it works?

[sudden grail]

hey, do you have any clue about the future/career options in django?

it's on a massive decline? or?

nodejs seems to be taking over on it

[hard umbra]

django is a web framework for python.

nodejs is a runtime environment for javascript.

like cpython is a runtime environment for python

[sudden grail]

i know

i know how to code etc i know quite well ts, react, node, typeorm, django

graphql

just don't know which way could be a better bet in long terms

[hard umbra]

django is a pretty stable web framework that doesn't change much these days.

both python and js are popular languages.

it depends on what you want to build.

[cosmic panther]

Thank you very much

[mint folio]

And depends on what the jobs are like or their demand is for django in your area

[sudden grail]

i look at this point about it career-wise

[mint folio]

I rarely see a job advertising django for where I live, but that’s my case.

[sudden grail]

not businsess

oh

got it

[hard umbra]

node has the big advantage that you can use the same language on both frontend and backend, since you are stuck with js in the browser. Python and django in the backend has the advantage that you don't have to change much about the backend each day because fashion changes.

[sudden grail]

yeah, true

I think I'm gonna apply for js and django jobs as well, and let see what my destiny wants to me 😄

[hard umbra]

I guess you will have to learn in any job.

[spare iris]

you always do

[weak lynx]

Hello there! Does someone know a boostrap template ofa single service? Like th products individual page with the description but with a service?

[mint folio]

What do you mean with a service?

[weak lynx]

like... mecanic, plumber or something like that

not a physical object

[mint folio]

Sure you can probably find them online, but maybe not as specific

[weak lynx]

im searching but im not able to find it

[mint folio]

Are you after a static site?

[vestal hound]

"service" tends to have a specific meaning

in the context of web development

[mint folio]

Because generally things like plumbers would just have static few page sites, or are you wanting something more dynamic data driven

[weak lynx]

static yeah, im searching for it, but im not able to find a template

[native tide]

hey

can i get some help with a issue regarding html?

[vestal hound]

just psot it

don't ask to ask

[mint folio]

There will definitely be templates for that, you just need to look in the right places. Some will be free, some are not. Depends what your after. You might want to check out startbootstrap, or bootstrapmade. Both have some themes.

https://bootstrapmade.com

[weak lynx]

Great, thanks i will chet it right now

thank you

[native tide]

so im making this project website to get some web dev down. And yk how you can press a button to go to a certain part of a page? like /#id, How would you do it so it stays on the same page but still goes to that part of the page?

[vestal hound]

okay

that's called

a URL fragment

and it works using the id HTML attribute

e.g.

<div id="to-me"></div>

can be accessed with #to-me

[native tide]

doesnt that fresh the page tho?

i tried that but

when i press on the one

thats suppose to bring me to #test it doesnt

and instead refreshes the page

and goes back to the defualt page

[vestal hound]

show HTML

nope

it shouldn't do that

it's probably

something to do with your href

okay just check Wiki for an example

https://en.wikipedia.org/wiki/HTML

inspect one of the links in the table of contents

<a href="#Naming_conventions"><span class="tocnumber">4.3</span> <span class="toctext">Naming conventions</span></a>

[native tide]

oh yea it seems to be working now

i never implemented it before asking

[vestal hound]

🥴

[native tide]

i thought it redirected to a new page

and thats how it loaded

by going to /#a

thanks

[vestal hound]

Does anyone see what the problem is?

[surreal horizon]

I want to use my flask app as a web app and rest api and I want to receive data from the api with JS, so this is what my JS code looks like ```js
const fetch = require('node-fetch');

const apiURL = 'http://127.0.0.1:5000/api/myapi/';

async function getISS() {
const response = await fetch(encodeURI(apiURL));
const data = await response.json();
console.log(data);
}

getISS();
For some reason it works when I run it with node, but i also linked my JS with to my HTML template and it gives me this error
Uncaught ReferenceError: require is not defined
at app.js:13

[opaque edge]

it possible to make a web page with python ?

[uncut spire]

does a good strategy for implementing a db connector with sqlalchemy change when going from gunicorn/flask to uvicorn/fastapi? like do i need to do scoped sessions and make an async connector for my app to take full advantage?

[umbral mulch]

Hey!!
I am working on a project where I want to 'watch' for a button on the webstie to see if it is clicked. i am using python and the website is dynamic including the button. Any way I can easily do this?
thank you very much for your help!!

[umbral mulch]

Flask man!

[pliant bane]

uh the information you provided is vague, but a hot take is on click, send a API request

thats what i do with a project of similar nature

[wooden ruin]

if you are simply "watching" for when it was clicked, just use some javascript and an EventListener

[inland copper]

yes

event listener and onclicked

[dense wigeon]

Anyone here with socket.io experience? I'm trying to run multiple tasks on my server while emit data. I used start_background_task to run a function which reads from serial port and emit data every time new data received. Now i want to do some calculation on that data, typically every time unit which will require me to have new independent task. But i failed to start multiple start_background_task. Any idea how i can solve this ?

from flask import Flask, request
from flask_socketio import SocketIO, emit
from flask_cors import CORS
from threading import Lock
from datetime import datetime
import json, time, serial, threading


app = Flask(__name__)
CORS(app)
socketio = SocketIO(app, cors_allowed_origins='*')
thread = None
thread_lock = Lock()


@socketio.on('connect')
def start_get_data_thread():
    global thread
    with thread_lock:
        if thread is None:
            thread = socketio.start_background_task(target=emitSolarData)


def emitSolarData():
    while True:
        try:
            data = serial.Serial('/dev/ttyUSB0',115200).readline().decode('utf-8')
            if data != None:
                socketio.emit('solarDataStream', data, broadcast=True)
                socketio.sleep(0.1)
        except:
            print("Failed to receive or send data")


if __name__ == '__main__':
    socketio.run(app, host="0.0.0.0", port=5000, debug=True)

Can anybody advice me on the package you would use to adapt Django Rest framework schemas. I would like to autobuild my form on basis of a schema so they match with https://vueformulate.com/guide/forms/generating-forms/

[tender crater]

I am using a simple class for all my tests in a Flask app. Is there anything wrong in the snippet below that might prevent the db from dropping all tables in between tests?
I don't get why the migration is actually being executed but tables don't get dropped at before it.

import unittest

from flask_sqlalchemy import SQLAlchemy
from flask_migrate import upgrade

from backend import create_app

db = SQLAlchemy()

class BaseTestCase(unittest.TestCase):
    def setUp(self):
        app = create_app("backend.config.TestEnvironmentConfig")
        self.context = app.test_request_context()
        self.context.push()
        self.client = app.test_client()
        self.runner = app.test_cli_runner()
        db.drop_all()
        with app.app_context():
            upgrade()
        db.create_all()

    def tearDown(self):
        self.context.pop()

Obviously in the postgres db logs I can see the db gets queried correctly

[quiet ridge]

hey @native tide

so where did you get the javascript cdn

okay lemme check

well can you please tell me things in more detail

this contain library for version upto 3.1.2

which one do you use

so which one have you used with the flask-socket 5.0.0

[wanton ridge]

how can i use SHA256 in Flask for hashing password?

[quiet ridge]

just type this while storing the password

[wanton ridge]

it says SHA256 doesnt exists

[quiet ridge]

import from werkzeug.security import generate_password_hash, check_password_hash

and then use ```py
password = generate_password_hash(password , method = 'sha256')

[quiet ridge]

please try this

do this when you are storing the data on the database

[wanton ridge]

yeah will try later on, i am at work right now

[quiet ridge]

okay fine

[rotund patio]

I am considering creating a personal/ portfolio website. I was just wondering if anyone had any advice on what hosting service to use (hostinger?) and what libraries/ languages to use (node, react, angular, html/css)? Thanks

[candid yew]

I need help with my html code

does anyone here know html?

I want all the lists to not be indented like that

[quiet ridge]

yup

well hey guys I m having some problem with the flask-socketio

lemme show you

[eternal blade]

Hi, I have some videos in my django site but it is taking pretty long to load.

[quiet ridge]

please help me

please check this too

[candid yew]

I need help

[nimble epoch]

did you try text-align to left ?

not sure just an advice

[eternal blade]

How can I improve the loading speed?. Thanks

[glossy osprey]

Hi all, first timer to Python Discord, so apologies if this is not the place. I am starting fresh in Django (though not new to python in general), and am wondering if there are any recommendations or best practices for implementing back-end recurring tasks (in unix land, "cron jobs") that can be managed throught he Django site. I've seen a lot of people jumping onto Redis and Celery, but those seem like overkill for a cron job that just needs to be Django context aware to update some models. Anyways, apologies again and hope this is the right place to ask!

[toxic flame]

Wdym indented?

Try float:left on all the "li"'s

[opaque rivet]

https://pypi.org/project/django-crontab/ I've also seen the majority of people use Celery, I haven't looked into it though, but this module looks promising

[minor ether]

hey guys im trying to coummicate with asp.net code and python code in same server or computer how can i do that most effectively?
asp will receive the request and forward it to python and vice versa

[elfin gorge]

can I somehow preset email field in views.py ?
class Online(models.Model): file = models.FileField(upload_to='online/') email = models.EmailField(max_length=254)

My intention is to set email field to email of authenticated user email.
I have tried: form = UploadForm(request.POST, request.FILES['file']) form['email'] = request.user.email

I'm using django

[formal gull]

i am making a flask app that can send a function through a selenium app that i have made. i need 5 people to be able to use it at once. is it possible to kind of assign a session to a new instance of it?

so that each person using it has their own browser and gets back their own information.

[hybrid bobcat]

hello guys, so like im currently using Flask for a stuff, and I wanna have a view function that have dynamic path. now i wanna each dynamic path to have its unique instance, so say if a user is on that path and then if a post request is made, only the instance on that specific path is changed, how is that done?

cuz i tried using a variable to represent the instance but once its chnaged on one of the path, all of the instances on the oher paths all changed

I don't wanna use databse btw

so like if a user can hold that instance as the session variable and the chnage (once the post is made), it will use websocket to emit to other connections on that path

so only the one on that path is changed

[spark swan]

hey guys. I am currently planning to make a selenium autocheckout bot which can be managed by a django website . I will also be using celery. Could anyone tell me where and how to host it? If there is a tutorial on it even better. So far i couldn't find a tutorial for it. Also I have to store some private info that is too sensitive but the bot needs to access it for checking out, etc where can I store it?

[autumn solstice]

which is better, django or flask? I am going to be designing a html frontend with bootstrap and need parts of it to work with python

[maiden tulip]

there is no "better", they do things differently and both are able to provide a website at the end. I think this article gives a bit of insight https://hackr.io/blog/flask-vs-django
in the end, the question is more likely: What is A: easier to learn and B: more of what you will do in your job later

[heady drum]

there is a way you can use variables in the path

@hybrid bobcat

[autumn solstice]

I understand. Which is more lightweight? I need it to use as little resources as possible.

[hybrid bobcat]

Yea but but like if I change the variable all of the variables on all the paths changed for some reason

[sonic stratus]

[fathom belfry]

I'm learning Django. can someone explain this syntax pls

def update(self, instance, validated_data):
"""
Update and return an existing Snippet instance, given the validated data.
"""
instance.title = validated_data.get('title', instance.title)
instance.code = validated_data.get('code', instance.code)
instance.linenos = validated_data.get('linenos', instance.linenos)
instance.language = validated_data.get('language', instance.language)
instance.style = validated_data.get('style', instance.style)
instance.save()
return instance

on validated_data.get why are there 2 values being passed?

[autumn solstice]

i have used bootstrap to make html, css and some javascript. However, i need to deploy it with some python functionality. In which of the following frameworks can i use the js functionality and use python backend for some functions? django or flask?

[shadow gate]

validated_data is a dictionary, here you are using .get() (it is a standard dictionary method) to get the 'title' key, otherwise defaulting to instance.title (the second argument)

[fathom belfry]

@shadow gate ahh that makes sense. thanks!

[plain dust]

I have

$('form#joinmeeting').submit(function(event) {
            socket.emit('joinmeeting1', {data: 'red'});
            return false;
        });

and in the form

<form id="joinmeeting" method="POST" action='#'>
    <input type="submit" value="I am in a meeting.">
</form>

but it doesnt cause the socketio function (first bit of code) to execute it just takes me to /currentpage#

[native tide]

(not exactly python webdev but still) How exactly does web based discord know when a message sent to a channel (not sent by you)

i.e. how does the server tell the client to update itself

[plain dust]

i am using flask

[plain dust]

what? i am using flask_socketio and the form should push to the javascript

[native tide]

i am asking question

not giving answer

[plain dust]

oh

right

theres no question mark

its confusing

also this channel isnt strictly for python web dev

[native tide]

si si

but it's a primarly python based discord server

so

¯_(ツ)_/¯

[desert parrot]

driver.get(url) Always returns "access denied, you donot have permission to view this site" :(

How do you create serializers with these data structures in DRF? ```
class AllPostsSerializer output:
{
"post_count": 2,
"posts": [
{ <data handled by another serializer> },
{ <data handled by another serializer> }
]
}

[fluid fable]

I'm not sure if this is the right spot to ask this question, direct me if there's a better spot:

Im using django and in designing my models, I have an interesting use-case for the User model (the model used for authentication). In my application, a User can either be a customer, or an employee. They both log in and have different permissions. The catch is that sometimes an employee needs to create a User as a customer (as one of their customers), and that new User cannot log in. It is just to be able to track that particular employee's customers. So to clarify, there are essentially two types of customers, those that can log in, and those who cannot. Other than authentication, they are stored with the same data. Is there a good way to implement this, potentially with class inheritance, to allow that separation between customers? or is the correct implementation to just create a User with no permissions to anything?

[manic frost]

You could make them both have a reference to a UserData structure, I suppose?

My conjecture is that it's absolutely accidental that their data is the same. Why can't that change in the future? So maybe the best way is to just duplicate the fields.

[fluid fable]

@manic frost Thanks for your help. Having a UserData parent may be the best way to go. The reason I would prefer them to be attached to the same table is because in the system they are treated the same. For example, if there is Project that an Employee is doing for a Customer, that project needs to be tied to the Customer, regardless of which type of customer they are. If I stored the two types in two different tables, how would the relationship table be able to tell which Customer table to go to? (the Foreign key from the Project to the Customer table needs to to be an id from one table)
