[graceful flax]

I want the other APIs to return 400 or 404 something I choose to if it is deleted=True

I don't want to manually write code in every API for this, was wanting to know a centralized way

[candid meteor]

i hosted it!

been so long been here

[candid meteor]

simply render the page

[graceful flax]

?

I meant in every API view function

I'm doing

post = getpost..
if post.deleted == False
         then updatedPost()```

I don't want to write this in every view function is what I meant.

[glacial yoke]

that's posgres, I was asking about MYSQL

[inland oak]

the page says: Postgres Specific Fields in Django ORM -> it mentions your Array field -> Logical assumption, Array field works only in Postgres -> Logical assumption: Array field is not working in MySQL with Django ORM

[glacial yoke]

well, I didn't specify it directly, but logically my question also asks if there is something like that in mysql

[jade moon]

Hi Pady. Check out https://www.dj4e.com/. You might find it helpful. There's also an 18 hour long video of it on FreeCodeCamp's Youtube channel https://youtu.be/o0XbHvKxw7Y.
Also if books are your thing, Django for Beginners by William S. Vincent is a good bet.

[tepid lark]

can you configure django to not use a default database?

i'd like it to fail rather than fall back if you don't specify what database your model belongs

[cinder sluice]

@tepid lark yes, you can leave out the database. most of what I've been developing this year has been APIs fronting services and I don't need the database. All you would do in settings.py is

DATABASES = {}

[cinder sluice]

got called into some other work, but inside this post there is a single file django application included in the discussion here: https://adamj.eu/tech/2019/04/03/django-versus-flask-with-single-file-applications/

[tepid lark]

@cinder sluice Thank you!

[next vessel]

i have no clue why it isn't creating a .db file
it doesn't even give me any error

any solutions?

app = Flask(__name__)

app.config['SECRET_KEY'] = 'kdljfkldjfdlkfjklf'
app.config['SQLAlCHEMY_DATABASE_URI'] = 'sqlite:///site.db'

db = SQLAlchemy(app)```

[outer apex]

You have a lowercase l for the database uri key.

[next vessel]

how tf i didn't see that

🤦

thanks

[warm igloo]

Did you inspect the Remove button in browser to see if the url that's generated is actually good? Because it appears that its barfing on the url being something like manage-users/delete-user/('',) instead of your expectation that userprofilelist.id is something like an int. So then it can't find a url pattern accepting that weird string. So I'd start there to confirm that the template is really making the URL what you expect

Hey I’ve been learning python for a couple months, doing dev work is something I might wanna do in the future.
Now I never done any web stuff but I would like to build an online store for my business. Would going and learning django be a good choice for that? Are the other routes I should consider, python or non python related?

[vestal hound]

yes, look @ frontend stuff too

Wagtail is another layer on top of django that may prove to be useful. Start with a relevant tutorial like https://snipcart.com/blog/django-ecommerce-tutorial-wagtail-cms and see how you go.

[lament birch]

Is there a way to obtain real time audio data from a user in a django web application?

[vestal hound]

websockets?

[coral storm]

do I need to use sqlalchemy with flask or can I use raw sql?

[bright mason]

you could

[inland oak]

whatever you find comfortable ;b

I would say, SQLaclhemy provides simpler output in terms of database management

all your database... tables are stored as a code

and changes from one database version to another one, is just a database migration code stored inside your project

it simplifies stuff a lot for simple projects development

Hey there, I'm hoping to build a dynamic website with user profiles and such.
I've been wondering what is the best python web framework to use in this case?
Flask? Django? Or FastAPI.
I've also been wondering if I should directly send all the content to the browser or use "static" pages with REST/WS APIs to load the dynamic content?

[native tide]

How can i get button onclick event to work?

i have this simple thing on web

and this in my code, how can i get the input from the input by the button click?

[warm igloo]

you need a form around it and the form determines where it goes

or you can use js and a listener

[native tide]

whats more simple?

and how to that, cuz im new to web developing and i cant find any info about it :/

[warm igloo]

I suggest pausing your python work and learning html forms first

I am trying to deploy my ASGI chat app on Heroku.. but I keep getting this error: django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

[warm igloo]

you've tested locally and it runs fine?

it's likely a settings issue from what I can tell reading online

a missing ENV, a misconfigured asgi.py

bad procfile

I am working on a web app using python and having trouble setting up virtual environment.
I have the latest Python3.9 installed. I am using VSCode. Windows
I have used the following command that is listed in the python documentation and I am trying to activate virtual environment py -m venv env
.\env\Scripts\activate

The result is a message saying 'Command not found'
-are there any commands I should do prior to this?
-I have tried activating inside and outside env folder.

is there a way to undo 'django install' on vscode termial?

[versed python]

So I am working on a banking platform, and when a new user registers, we need to send the submitted data to that user's country's trusted verification API (for eg: SendWyre for US). Now as you can imagine each API has different requirements.

Is there any way I can use a common function to somehow contact all the API's or is it necessary to write a separate function for each?

[versed python]

looks like you are trying to run windows commands on a bash terminal?

[olive patrol]

Do you mean uninstalling Django?

so it shows error

not sure

[dusk portal]

this is the error

Ao turns out, my web application had a sys.exit() error because of gunicorn, I am not sure what caused this, how should I go about diagnosing the problem?

It seems like the request took 30 seconds for some reasons? But how would I know what caused such a timeout? I had a suspicion of the omage upload in said view as it sends it to Cloudinary, but that took 1-1.5s to complete not 30

[hasty glacier]

Hi all - has anyone here deployed Django / React with Azure App services that I can pick their brain? I'm having a problem with my main.js not being found after I've collected statics and declared the static location.

[terse vapor]

current_time = datetime.now() 
time = timedelta(weeks=4) 
month = current_time - time
filter_by_month = db.session.query(Patient.subid).filter(Patient.create > month).all() 

This is my script for filtering patient per month, but is there a method that allows me to get all the list for each month?

[fickle garnet]

cant just increment?

[inland oak]

not enough background to understand/answer the question

[terse vapor]

i have a list of patient in my database, and i have already filter them by current month and day, but im trying to filter the amount of patient for each month(Jan - Dec) (i hope this can make a bit clear)

[inland oak]

so, you can query their amount/set in a specific month
but you wish to acquire their amount/queryset for a year?

how your database customer table looks like?

[terse vapor]

the first part was right, and for second part, sorry for my bad explanation, i was meant to say from jan to dec, amount of patient for each month

[inland oak]

so you wish to acquire in one request, amount of users in separate months, not one value for whole year

[terse vapor]

yup

[inland oak]

sounds like SQL grouping

I am a bit rusty on SQL, but I know for sure that it is possible

in raw SQL it involves syntax words like Group By, Having

[terse vapor]

that sounds like a great idea

[inland oak]

https://docs.djangoproject.com/en/3.2/topics/db/aggregation/ for Django ORM should work

[fickle garnet]

For an sql query its just as simple as a GROUP BY var_name clause isnt it ?

[inland oak]

https://sqlbolt.com/lesson/select_queries_with_aggregates

SELECT AGG_FUNC(column_or_expression) AS aggregate_description, …
FROM mytable
WHERE constraint_expression
GROUP BY column;

and having aggreating function

https://sqlbolt.com/lesson/select_queries_with_aggregates_pt_2
plus potentially can involve HAVING, not sure how it applies 🤔 I am too drunk to think about it

[fickle garnet]

HAVING would specify a particular month. SELECT COUNT(*) GROUP BY(month)

i should use code so it doesnt look like im yelling at you

[inland oak]

nah, that will work too. having big SQL syntax is... normal.

[fickle garnet]

syntax handed down from old wise peoples

does nginx -> wsgi -> flask make sense for a small project ?

[inland oak]

it does for everything

because we use gunicorn as default for flask wsgi

and it can't serve static files

nginx is the best default option to serve static files

other things... like white noise just literally suck at serving static files (taking up to 4 seconds to serve one file)

old alternative solution could be using Apache, but I think Nginx is better, easier and faster at the moment

[wooden ruin]

wow i didn't know whitenoise sucked that bad with static files

[inland oak]

I learned it the hard way

😆

[fickle garnet]

haha hopefully not production env

4seconds.. ahhh!

[inland oak]

thankfully in dev env

plus with nginx you can easily setup additional things to speedup your website by about 100 times with minimum effort

you just enable http2
client side caching (static files css/js will be cached at the client side and will not be requested again until time expries)
and server side caching for urls you can (nginx will serve cached version of the particular url, before the request reaches your python framework

the book is free how to do that

https://www.nginx.com/resources/library/complete-nginx-cookbook/

[fickle garnet]

what do you think about uwsgi ?
does nginx still detect and cache static content generated by flask ?

[inland oak]

you mean by those jinja2 templates?

[fickle garnet]

yes

[inland oak]

yes

it can cache even JSON requests of your REST API end points (making one request to database and caching it 🙂 )

[wooden ruin]

wow

[fickle garnet]

i knew this to be true from experience, had to tell it not to cache to troubleshoot some stuff... just checking im still understanding 🙂 thanks mate!

[inland oak]

at least it is working perfectly for GET requests, that I checked

it can cache separetely requests like url?one_var=123&other_var=32434

it will serve/cache the right answers for different query_params

not sure how it works with POST requests since they have JSON data paylod 🤔

[fickle garnet]

it was working perfectly. it was my implementation that was awkward

making me curious but i must resist the rabbit hole

there are passthrough options... thats all i know haha

[inland oak]

quite deep rabbit hole, I tested. still falling.

[inland oak]

I am still torn apart, if I should apply Vue or Svelte at the startup 🤔

Vue looks like safer choice, but Svelte is so attractive and easier

[inland oak]

eh. the size of usage Vue and its community leaves me no choice but to choose Vue

Svelte is so super attractive, clean, small coding, but I just can't choose it for startup/commercial because of small community and small percentage of usage in commericial (50 times difference at least)

[olive patrol]

I have these two elements: text hello world. Text being a paragraph element, and hello world being a button. How can I make it so that if the button is clicked, it deletes the paragraph element and the button element itself?

[tepid wren]

svelte is easier than vue ? vue was the only js framework I could work with

[inland oak]

yeah, svelte is even easier than vue.
https://www.youtube.com/watch?v=cuHDQhDhvPE check comparison of the same program in Vue and Svelte

less code, plus I heard inbuilt nice testing framework.

[tepid wren]

okay I will check thanks

[tropic raptor]

Hello,
I am struggling with getting Set-Cookie header's session value created by Flask-Login.

from flask import Flask
from flask_login import LoginManager, login_user, UserMixin

app = Flask(__name__)
app.config["SECRET_KEY"] = "abcdef"
login_manager = LoginManager(app)


class User(UserMixin):
    def __init__(self, identificator):
        self.identificator = identificator

    def get_id(self):
        return self.identificator

    @staticmethod
    def load_user(user_id):
        user = User(user_id)
        return user


@login_manager.user_loader
def load_user(user_id):
    return User.load_user(user_id)


@app.after_request
def ar(response):
    print(response.headers["Set-Cookie"])
    return response


@app.route("/")
def main():
    user = User(1234)
    if user is not None:
        login_user(user)
        return "Should be logged in"
    return "At first log in"

Minimal piece of code ^

Unfortunately, there is not Set-Cookie header in my response.

However, each time I call / endpoint, I see HTTP response in my curl - containing Set-Cookie and session=.eJ... headers!

How to obtain that session cookie value in my Python code?

[inland oak]

the biggest killer feature, that svelte is not shipping virtual dom and instead it is lightweight compiler into regular javascript

the size of its build... 10 times smaller than any other framework

[tropic raptor]

Yea, I do recommend Svelte!

[tepid wren]

so many javascript frameworks makes me feel lost

[inland oak]

I was able to throw away other frameworks for some reason or another one

anything that is not React/Angular/Vue/Svelte, throw away because of too small communities / low interest

Throw away React, because it is dirty mix of html / javascript / jsx in one code line

Throw away Angular, because long learning curve, suspiciously small developer satisfaction.

This makes remaning only Vue and Svelte to choose

Vue looks good and solid choice. High job market percentage, community, looks good from afar. 😉
Svelte, looks so super clean, lightweight, easy to learn, battery included (even for state management!) quite attractive and promising to be great in a future. But low job market occupation 😦

[tepid wren]

when I had a work project I choosed vue because it has vuetify package to make ui creation easy lots of ready made components, svelte has something similar ? cause my css html really sucks

[olive patrol]

Is there a way of doing this with Django? I am aware that it's possible to do it with JavaScript, but there were some issues with doing it in JavaScript

[indigo kettle]

I mean you could do it by navigating to an entirely new page that doesn't have those elements on it, but you should really just do it with js

what was the issue with js?

@olive patrol

[olive patrol]

Whenever all the items would get deleted, they would just come back to display. I’m assuming it’s because the elements are stored in a database, and I’m getting those elements fork the database and displaying it onto the screen

[indigo kettle]

do you have some interval on the frontend which is polling the backend and displaying that data every x seconds or something?

[olive patrol]

No, I’m just getting the items from the database and allowing the html document to be able to display it

[indigo kettle]

That's just what happens on page load, right? So once you click the button and the elements are removed, they shouldn't come back

[olive patrol]

When I use JavaScript, they’re getting removed from the display, but not from the database itself

[indigo kettle]

ah

Well then you will have to send a request to your backend so it will handle it

So maybe you do want it to be handled by django and not js after all

you should maybe create a form which sends a delete request to your backend for the exact model ID you want to delete

then your frontend will refresh that page, probably and the item should be gone

[olive patrol]

How would I get the id?

[indigo kettle]

if you have created a database row then the django model will have an id attribute

that is the database id of the row

[olive patrol]

Can I do Model.id to access it?

[indigo kettle]

if you have an instance of the model, then yes

like if you have a Todo app and you want to get a todo id

todo = Todo.objects.first()
todo.id # is the id

[olive patrol]

What about with ForeignKeys?

[indigo kettle]

?

[olive patrol]

My structure looks something like this: class Category(models.Model): … class SubCategory(models.Model): subcategory = models.ForeignKey(Category, on_delete = models.CASCADE)

[indigo kettle]

and you are trying to delete the subcategory?

or category

[olive patrol]

subcategory

[indigo kettle]

even with foreignkeys, the model still has an id

[olive patrol]

Now what if there are more than two subcategories? I won’t be able to get the id with first() or second(). What would I use then?

[indigo kettle]

when you render your html I assume you're iterating a list of subcategories right?

[olive patrol]

Yes

[indigo kettle]

like for subcat in category.subcategory_set

then within there you can send the id to the frontend

and your frontend needs to send the id of the subcategory you want to delete to your backend

your backend shouldn't have to decide what to delete

[olive patrol]

How would I send it to the backend?

Hey folks, how can I use track argument inside iframe?

        <script>
            function PlayTrack(track) {
                document.getElementById("iframeMusicPlayer").innerHTML = "<iframe src=\"track\" height=\"150\" width=\"400\" ></iframe>";
            }
        </script>

[glacial yoke]

when using DRF if I wanted to make a post function, to post info from the frontend to the backend, would I be able to return a response, which then I would be able to grab from the frontend? or would I have to create a get function as well, inside that APIView so that I can return a response to the frontend

ok, nvm, just tested it out

you can just return it through the post function

if you are using a js framework, then you can use axios like this to not just post your data to the backend, but also receive whatever you need back, from the same function:

axios
      .post(
        "function url",
        {
          whatever_you_are_posting: "whatever you are posting",
        },
        config //the headers with csrf token, can't make a post request without them
      )
      .then((response) => {
        console.log(response.data) //Do whatever you need with the data that you receive
      })
      .catch((err) => {
        console.log(err)
      });

https://stackoverflow.com/questions/69428221/javascript-how-to-process-argument-within-innerhtml-iframe

[dim rover]

is the iframe on the same domain as your parent page?

[native tide]

Yes.

Its just to include a audio player from the same domain

[dim rover]

then you can use iframe.contentWindow

to access the window/document inside it

like if you have a function in the iframe, you could call it from the parent page and pass your argument, right?

[native tide]

Please have a look at my stackoverflow question, I actuslly just need to know how to format the string, any idea?

[dim rover]

document.getElementById("iframeMusicPlayer").contentWindow.PlayTrack(track);
``` something like that?

oh, ok

you could use onclick=document.getEl....

same way

Hello! I am attempting to use uvicorn[standard] for handling websockets requests. I am using Nginx as my web server and doing a reverse proxy to uvicorn for all websocket requests. I can get uvicorn running, but once the websocket request is made, I get an error from unvicorn saying WARNING: Unsupported upgrade request.

Here is the command line I used for running uvicorn uvicorn --log-level debug --workers 3 --uds /home/ubuntu/personal_site/app.sock mysite.asgi:application

I also want to mention that just in case I accidently downloaded the regular uvicorn, I uninstalled it, and then reinstalled it using pip install --no-cache-dir uvicorn[standard] , but I am still getting this error.

I can't seem to figure out why I keep getting an unsupported upgrade request. Could someone point me in the right direction

Also, just in case, here is my NGINX config file

Hi, I've been bashing my head on something the past days tat I can not seem to find the answer to.

I'm building a password manager in Django and I'd like my password field to be hidden like a pw field usually is.

I think there's a mismatch between versions of python and django

there were some changes made in syntax which is not supported in older versions of python or vice versa

if you are in the latest django, downgrade it, if it's not about that then your python is either too old or too new

should work fine

Yes I did but it seems that the second.html doesn't render

[indigo kettle]

well, when you do this

{% block body %}

{% block events %}{% endblock events %}

{% endblock body %}

I believe you are completely overwriting your previous body

actually that's fine

when you say it isn't rendering, what is it doing?

is there an error? is the page just blank

[muted scaffold]

The second.html file's content is not shown

[indigo kettle]

can you paste the view as well?

from django.shortcuts import render

# Create your views here.
def home(request):
    return render(request, 'main/index.html', {})
    # return HttpResponse("<h1>This is a Home Page :D</h1>")

you aren't rendering the second template

flask does not do HTML templating but you can use jinja2 for templating together with flask

how does that work

you call a function with the template name and a python dict (ca same as js object) with the key/values you need

Domain privacy is hiding who is the domain owner from services like https://who.is/
instead of showing you, it will be showing generic hosting service information

I think this is exactly what I need.

[lyric belfry]

Can I use a model inside a model?

What I mean by this is can I make say a class for the following

class Comment(models.Model):
  text = blah blah blah django stuff

class User(models.Model):

  comments = []

``` could I then use that layout from the comment class inside like an array?

would that allow me to pull attributes? say I did User.comments[0].text

[dire urchin]

I'm not sure I understand the question exactly, are you trying to set up a foreign key?

something like

class Comment(models.Model):
  text = blah blah blah django stuff

class User(models.Model):

  comments = models.ForeignKey(Comment, on_delete=CASCADE)

this way you can link the User's comments field with the Comment model, but ignore this if I misunderstood the question

[lyric belfry]

I'm new to django if you couldn't tell what does the forgeign key do?

I've done things like pygame before so what I mean is could i use a different class and then use those objects inside another class? Like for example in pygame I could make like an class Enemy: and then make like an array called enemys = [] and then just append the enemy object into that array

Could I do the same thing with the comments?

Do you get what I mean? lol

Like use an ArrayField() and then append the comments into that?

It's for my project we bascially have to wrap our pygame project into like a web interface and im just using django because i already know python

[dire urchin]

a foreign key would define a many-to-one relationship here, so one User would be able to have many comments(field) which point to the Comment model

full disclaimer i'm also pretty new to this stuff so my explanations are probably bad, hopefully someone more storied can chime in and correct me

[lyric belfry]

What's the format of the foreign key?

[dire urchin]

this might be of help https://docs.djangoproject.com/en/3.2/topics/db/examples/many_to_one/

[lyric belfry]

Like when I call the attribute comments?

Can I use a foreign key inside an array field?

from django.contrib.postgres.fields import ArrayField

class User(models.Model):
  comments = ArrayField(models.ForeignKey('Comment',on_delete=models.CASCADE))

Like something like this?

I'm just asking before testing so i dont end up like destroying my db

and have to start the django project again

lol

[dire urchin]

i think there's no need for that
if you want to access a comment with the id 4 you can filter it from the database like this

comment = User.objects.filter(comment_id=4)

[charred epoch]

Hey im trying to use a variable from a js file to an html:

var api_key = "..."

<script type="text/javascript" src="restricted.js">
const youtubeKey = api_key;
</script>

but this doesnt seem to work

[lyric belfry]

What's not working?

Why would you set youtubekey to api_key if api_key is already it self?

Can't you just use that on it's own

[lyric belfry]

I wanted to like attach the comments to the user tho

For like organisation sake

[charred epoch]

i want to hide the api_key in another file far from the main code

so that only "api_key" is visible

[dire urchin]

read up on database relationships, i think this is exactly what you'll accomplish by setting up a foreign key

[vestal hound]

you probz don't want an array field of foreign keys, but just a foreign key there

which should be on the Comment model instead

[honest tartan]

guys i got this problem,my api in django is not caching the data in the request body to send to db,here the error:

[orchid olive]

is python-flask a good option to setup a home-webserver? or do i need something like apache web server?

[warm igloo]

well, what are you wanting to do? and host?

[orchid olive]

local service using python-flask

[warm igloo]

a single app for yourself? flask could run like that internally .. but if you want to host lots of stuff, that's a different thing all together

[orchid olive]

you have the idea, yes

[warm igloo]

sure, you coudl write a single app and run it on a machine and have it listen to a port

[orchid olive]

large service application

[warm igloo]

for instance, I have a homelab and I host LOTS of things

[orchid olive]

multiple users

[warm igloo]

multiple users like how many and you plan to do this on a server in your home then do port forwarding to it from your router?

[orchid olive]

over 1k at the same time 24/7

[warm igloo]

yeah, no, you wouldn't want to host that via the simple server flask can throw up, you'll want nginx/apache or something in front

better yet if you know about containers and other things because then you can do real cool things

but ultimately, you're better off hosting what you want out on a real host and not over your home connection

your isp will likely have a clause forbidding that much incoming traffic

plus it'll bottleneck a bit because your download speeds may be high, but your upload is probably hella slow

and again, just so much better to host outside stuff for outside people in the outside

[orchid olive]

no uploads, only data service

[warm igloo]

you can try it, but that's a lot of incoming connections that I bet your ISP will pay attention to

depends on your contract with them

[elder ledge]

Hi, guys. I am looking for and need help from you for a django project.
If you have skills and experience, and interests on it, feel free dm to me

[orchid olive]

ok, got it, thanks for the adivice

[warm igloo]

If you have questions, you can ask them here.

[warm igloo]

And please don't be asking to pay for work; that's against server rules.

[warm igloo]

But if you still want to host it yourself, yes, put a webserver up in front with wsgi (like gunicorn).

[lethal junco]

hello can someone help me with my problem?

whenever I click a category, that's the error

[mild hazel]

Hello, so I'm trying to learn Flask and long story short I got a problem with some code and no idea why it even occurs or how to solve it, I'm new to programming and quite inexperienced, my .py code is this:

app = Flask(__name__)

posts = [
    {
        'author': 'John Doe',
        'title': 'Blog Post 1',
        'content': 'First post content',
        'date_posted': 'April 20, 2021'
    },
    {
        'author': 'Jane Doe',
        'title': 'Blog Post 2',
        'content': 'Second post content',
        'date_posted': 'April 21, 2021'
    }
]

@app.route("/")
@app.route("/home")
def home():
    return render_template('home.html', posts=posts)

@app.route("/about")
def about():
    return render_template('about.html')



if __name__ == '__main__':
    app.run(debug=True)```

and my .html code is this:

```<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    {% for post in posts %}
        <h1>{{ post.title }}</h1>
        <p>By {{ post.author }} on {{ post.date_posted }}</p>
        <p>{{ post.content }}</p>
    {% endfor %}
</body>
</html>

All I keep getting is a damn "jinja2.exceptions.TemplateSyntaxError: tag name expected" error message.

Hey! Anyone up? I had a query regarding Flask

[coarse shadow]

!code-block

[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.

[inland oak]

[foggy plover]

I am working on a React-Flask project and I am getting this error,
TypeError: The view function for 'logout' did not return a valid response. The function either returned None or ended without a return statement.
Where I am returning a response. The Code is

@is_logged_in
def logout():
    if request.method == 'GET':
        session.clear()

        return 'OK'
    return 'NOT'```

[inland oak]

from flask import jsonify
return jsonify(status="OK")

as a choice

you can also return any complex dictionary of information in the jsonify

from flask import jsonify
return jsonify({"status":"OK", "another_var": 123, "or_even_entire_list": [1,2,3,4]})

you will be able to query those endpoints from react with fetch operations

[foggy plover]

Sure, I'll try this.

Here's another error. I am using sessions from the flask library to work with sessions but I am unable to get the session variables.

Here I am setting the session, if dbm.check_login(username=username, password=password): session['logged_in'] = True session['auth'] = auth.get_auth_key(username=username)

And I am unable to access the same here, ```
def is_logged_in(f):
@wraps(f)
def wrap(*args, **kwargs):
print(session)
if 'logged_in' in session:
return f(*args, **kwargs)
else:
return {'error': 'Session Expired'}

return wrap```

[inland oak]

flask provides with auth library actually named login manager

it would be less reinventing the wheel solution

[deep tinsel]

Hey guys, just to confirm it, you can create a website with PyCharm only, right?

[lethal junco]

yes

[deep tinsel]

Oh that's cool

[native tide]

how do I import in brython from django's static?

[lethal junco]

I'm using a PyCharm right now creating an E-Commerce

[native tide]

I'm redirecting <slug>.py but that doesn't work for directory modules

[deep tinsel]

Damn, it is not possible that you can teach me how to build a website, is it? I am interested in web development, game development and cyber security, so it would be great if you could teach me sum

[lethal junco]

have you develop any website using Python?

[lethal junco]

I suggest you start watching on how to develop a website using Python, for starters you can use Django as a framework

[native tide]

I'm trying it with django with brython. Not having to deal with javascript is so nice.

[native tide]

nvm I got it

[deep tinsel]

My guy

I started using python for 6 days ago

[lethal junco]

I see, after you learn Python, start learning Django Framework

it's easy to understand

[deep tinsel]

Got it

Well

Can i create a website with PyCharm only or?

[lethal junco]

I don't understand this, you're talking about the IDE not the programming language right?

if so, yes PyCharm can develop a website

[deep tinsel]

Legit

Because I do understand a bit python yk

But I am hella interested in web development, game development and cyber security

[lethal junco]

if you understand python then you will understand Django easily

[lethal junco]

it's fun developing website using Python

I came from PHP but when I learned Python, I switch immediately to Python and start learning Django

[deep tinsel]

Is there much different between dj and python?

[lethal junco]

Django is a framework came from Python, some people use Django as a back end for their website, some use Flask

[deep tinsel]

So ehm

Lemme ask you dis question

Is it possible you can teach me how to build a website?

[native tide]

Pretty sure the subject is a bit too complex to be taught by one person over discord. You have to "do your own research"

[deep tinsel]

Yea but the thing is

Idk what the fuck I gotta search

Should i really just go on fucking YouTube and search "how to build a website using PyCharm"?

[native tide]

no, you search "how to build a website using python"

pycharm is just an ide?

[lilac solar]

PyCharm is 'just' a fancy editor designed to make writing python easier, not sure why you're so fixated on it when it comes to web development. In terms of Django start here: https://docs.djangoproject.com/en/3.2/intro/install/

For flask start here: https://flask.palletsprojects.com/en/2.0.x/tutorial/

[native tide]

fyi, you don't need fancy editors to code, you could even make a website with python using just notepad

[spark dagger]

hi can someone help me with django channels here

with auth specially

[honest tartan]

hey guys can anyone here help with a django jwt issue?

[lethal junco]

I suggest you watch Django Tutorial so you have an idea of step by step on creating your own website

[deep tinsel]

Which I mainly use

Thx

[lethal junco]

here you can watch Mosh, he's a very good teaching things and you can understand it very easily

[foggy plover]

Hey! If we are taking formData input type at the frond-end in react, then how can we handle the same at in flask?

At the frontend it is being stored like, formData: new FormData()

[lethal junco]

if you're very new to programming and never learn any programming language, it will be difficult but if you have any programming background it will come to you easy

well for me anyway

[dusk portal]

dont crack jokes bro

i was good in web d foundations before jumping into django

i was a flask dev

if u wanna be a noob just do less time

but for practice different use cases

different places different methods

for a big

intermediate n a small app too

u need to give time

if u wanna be a good dev

[lethal junco]

indeed, more time, more effort

[dusk portal]

yes

[pulsar lance]

Having an idea of how things work and being able to put it all in different case scenarios is a different thing!

[dusk portal]

no more discussion

i wanna be sigma male

so just told my suggestion

u can surf yt n all for more info

if u just wanna make simple app it will take less then a day

but to master foundations 3 months

and for advaned stuff more 2-3 months

[frank shoal]

In flask, you access formdata using request.form

[dusk portal]

ig its request.FORM.get

[foggy plover]

Sure Man. I'll check

[frank shoal]

!d flask.request

[lavish prism]

flask.request

To access incoming request data, you can use the global request object. Flask parses incoming request data for you and gives you access to it through that global object. Internally Flask makes sure that you always get the correct data for the active thread if you are in a multithreaded environment.

This is a proxy. See Notes On Proxies for more information.

The request object is an instance of a Request.

[frank shoal]

!d flask.Request.form

[lavish prism]

flask.Request.form

property form: ImmutableMultiDict[str, str]```
The form parameters. By default an [`ImmutableMultiDict`](https://werkzeug.palletsprojects.com/en/2.0.x/datastructures/#werkzeug.datastructures.ImmutableMultiDict "(in Werkzeug v2.0.x)") is returned from this function. This can be changed by setting [`parameter_storage_class`](https://flask.palletsprojects.com/en/2.0.x/api/#flask.Request.parameter_storage_class "flask.Request.parameter_storage_class") to a different type. This might be necessary if the order of the form data is important.

Please keep in mind that file uploads will not end up here, but instead in the [`files`](https://flask.palletsprojects.com/en/2.0.x/api/#flask.Request.files "flask.Request.files") attribute.

Changelog Changed in version 0.9: Previous to Werkzeug 0.9 this would only contain form data for POST and PUT requests.

[cerulean badge]

(context django) i am making a chat app which have models Chat and Messages.
when a user adds a new contact
i create a chat object and send a message to a group containing all channels (i named the group global)
and then check if the connected user is member of the chat , if yes then add it to group of that chat

my question is
should i be sending a message with the socket to create the chat app or do it with just ajax and send the message to the group in the save method of the Chat?

[turbid horizon]

I know that this is a pretty general question but one of my cousins suggested that I build a webapp that runs on a python server for a school project. The problem is that I have no clue what that is and whenever I google what that is it just gives results on how to make one not what it is. Sorry if it is obvious but thank you if you can help me. Even if you can share a link or anything like that it can help.

Hey! How can I serve an image file saved in MongoDB? Any solution instead of saving the file locally?

[frank shoal]

you should save images and other blobs on a filesystem.

though with mongo, it uses bson, which supports raw bytes.

[foggy plover]

Okay, so I should save all the files in the file system only?

[frank shoal]

[plucky heron]

pydantic question.
Is there a good way to make all fields optional for a query but make them dependent. In case of one query arg is used few others must be used?

[turbid horizon]

I am going to start learning how to make webapps but I am unsure whether to use flask or fast api? Which one will be better/easier to learn?

[warm igloo]

Well, are you wanting to build APIs (which both are good at), or a website (which I'd say Flask is better at), or what?

[native tide]

is there a point to having jquery if u have react

[calm plume]

Nope.

[native tide]

html, css, django(python), JS, react, jQuery, SQL for this would u just take out jQuery

[calm plume]

Looks about right

[native tide]

i thought jquery did its own thing

why pop it off

[calm plume]

When you have JSX, there's no need for jQuery

I want in my program that when a person select a word, with that word appear in a file txt and can upload it

someone to help at priv

[scarlet crater]

im not to sure what would be the best option for me to use, but im webscraping data off of a website which i want to then display on my own website. how should i do this

currently the only option i know of doing would be sending the data with socketIO to a node server but is there any python packages which allow me to edit a webpage like this?

[candid meteor]

how do i promote websites/social apps

[native tide]

um hello what editor can you use for javascript?

[calm plume]

VSCode is the most common one from what I've seen, but Webstorm and others are used too

[native tide]

thanks

[native tide]

is javascript better or html/css for a website?

[vestal hound]

you need both.

they do different things

[native tide]

ok

[hot granite]

in flask routes can you make *args? i mean

@app.route('/route/*')
def route(*args):
    return str(args)

/route/a1/a2/a4/
['a1','a2','a4']

[jovial cloud]

You can use query parameters and access them in your 'route' function instead

[hot granite]

yeah, but im asking is there a way to do like this

i mean ofcource there should be a base route get method, maybe i can overide that instead if there is no *args, but i just cant find that function

[jovial cloud]

I don't understand what you mean by overriding. What exactly is your route/function supposed to do(maybe I can help with that)?

hey peeps! Any django-crispy-form wizzards around?

I seem to have a question that has no answer in the docs

I am trying to set type attribute for an input field but not sure of the **kwarg name and can not seem to find it anywhere... it's not type, as type() is a reserved keyword. there's ref. to class for which is css_class but not for type

I am trying to render a form with crispy.helpers and this form is meant to have password field that can be toggled and I'd like to achieve this without setting a widget

[uneven radish]

I'm making a simple Django project (Todo Application)
So, let's say there are multiple users and they login and add a Task.
Now, while displaying a task, I have used slug in URL to display a particular Task (for that particular user)
Now I have added slug as unique for that Created date (when the task was created). This works fine but when I try to save a new task under another user with the same slug for lets say user X, it shows error. Which is expected.

How can I avoid this behavior? Is there a way where I can limit slug uniqueness only to particular user and particular Created date. But not globally.

That is, multiple users can create same slugged Task for any particular day, but one particular user when creating a new task for that day should get and error that this task is already added.

Hope this makes sense.

In short, unique table for every user.

Hey guys so I am following a tutorial and it tells me to do this step

This one

So I tried making templates.py but it didnt work that way

So can please some assist me on how to do this step?

Anyone????

[uneven radish]

I'm not sure why you will need templates.py

You need a directory "templates" in your app directory, which will store your HTML files.

Project
-->App1
------>templates
---------->App1
-------------->index.html
-------------->something.html
---------->base.html
-->MyWebsite

[thin crystal]

Anyone else here build crawlers? seems like the best channel to ask in

[fickle garnet]

whats the difference between a crawler and a scrapper ?

[thin crystal]

a crawler's primary purpose is indexing

to be found, not to keep

[fickle garnet]

i remember spider

crawling though html is straight forward enough right ?

[thin crystal]

yeah very, it's doing it at scale that becomes complicated

you want to crawl a page or two, that's cake. You want to do 20 million pages a day, that's a bit more complex

Hi can anyone please help me? i am trying to pre populate the wtf form from given data but its not working for some reason !

        form.content.data=prevLetter.content

    return render_template("write.html",form = form)

what does your template/html look like?

ah i figured it out. i had script tag clearing my text fields

lol sorry to bother

[native tide]

no problem at all

[native tide]

i'm donig python exercises and i didn't know the list() method can turn a list into an array

i'm perplexed by that

is it different because of how an array is stored in memory as opposed to a list? In python at least

oh my god i'm an idiot sorry guys.

so what i had was zip(*2d_list) and that zip function returns a damn zip object which returns a tuple
doing list((1,2,3)) turns a tuple into a list lol

it does indeed

do you need it to be a list?

I have connected my Django server to PostgreSQL, created 2 tables for car and driver with help of python manage.py migrate, then removed those tables inside the PostgreSQL bash with help of DROP table, but now I still have them inside my permissions

but there are no car / driver tables in database

Advice: If you're going to do db migrations, do db migrations. Don't mix doing migrations and manual changes.

[terse vapor]

i got a question regards python web scraping, i saved all the data for each section(title, date, etc) in a indivisual list, and saved in a big list, something like list = [[title], [date]], and access by index element. However is there a method allows me to find any match string as my target item inside the date and remove all the text with that index element

[native tide]

Hew what does {%%} this trype of thing do and where to learn about it

in html

[raw compass]

Its a templating engine! Are you using jinja2 with flask by any chance?

[candid meteor]

flask 😭

darkwind 😐

why are you telling me what {% does

[inland oak]

Ops, wrong phone number

[raw compass]

Not necessarily a loop. Though yes the engine allows loops. such as

    <ul id="navigation">
    {% for item in navigation %}
        <li><a href="{{ item.href }}">{{ item.caption }}</a></li>
    {% endfor %}
    </ul>

[inland oak]

It introduces loops over arrays and dictionary data, if conditions and other programming logic into your html code writing

Allows writing much... Smaller code to write html and css (or even js). Especially useful for menu and tables for example

[native tide]

well i kinda understood is is like a var to store you html so u can reuse it

[inland oak]

That is too

The main purpose is DRY, to have much more reusable code

Defining menu code once for all pages in the site for example

[native tide]

like a nav bar

[broken harness]

Hello everybody \o/

Decided to make myself a basic website using python \o/

[native tide]

ok

advil?

[broken harness]

yes

loads

[native tide]

oh

[broken harness]

sure

[native tide]

i maen

[broken harness]

idk what advil is but i'll take 3

[native tide]

the service

search it

[broken harness]

oh im using Django with python

[native tide]

for python

oh

sheesh

same

[broken harness]

is django not the best? 🤔

[native tide]

well

no

php is better

[broken harness]

😦

[native tide]

then node.js

[broken harness]

😮

[native tide]

😉

ur welcome

if u want to rebel

use c#

[broken harness]

if i wanted to be difficult I'd use straight up C or even binary to program my website

[inland oak]

bs 😉

[native tide]

it is

100%

then node.js takes over

[inland oak]

js in backend, still bs ;b

[native tide]

its quicker and better

faster html files

[inland oak]

well, yeah, quicker I guess a point

[native tide]

more framworks

[inland oak]

I am thinking to go for golang as next lang

it fits my dev path better

[native tide]

GO?

[inland oak]

yeah

[native tide]

just 'go' hahah, with rust

think of the long run

[inland oak]

rust is used 10 times less than golang in job vacancies

about what am I supposed to think

[native tide]

its going to be the most used

[jaunty depot]

hello
I decided to help out my friend and make her a website for her business. So far it's been going smoothly, but I've never done any page at all and now I've bumped into a problem that I can't resolve
I wanted to make a navigation bar with some buttons and an icon. I wanted to make the three buttons evenly justified and to that I wanted to add an icon to the left. However I can't make it "jump" in line with those buttons. I have made some attempts, unfortunately non of them worked for me.

could anyone point me to my desired result? I would be very grateful
My code looks like this:

html

        <img src="static/icon.png" width="60" height="50" alt="icon" style="vertical-align:bottom" >
        <!-- <ul><li><img src="static/icon.png" width="60" height="50" alt="ikona" style="vertical-align:bottom" ></li></ul> -->
        <ul>
            <!-- <img src="static/icon.png" width="60" height="50" alt="ikona" style="vertical-align:bottom" > -->
            <li>Offer</li>
            <li>Contact</li>
            <li>About</li>
        </ul>
    </nav>```


css
```ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    background-color: rgb(30, 57, 88);
    display: flex;
    justify-content: space-around;
}


li {
    font-family: sans-serif;
    color: rgb(255, 255, 255);
    /* text-align: center; */
    padding: 16px 16px;
    text-decoration: none;
}

li:hover {
    background-color: rgb(86, 152, 190);
}```

I tried to make two unordered lists side by side, but that didn't work either, that's why I have those img sources in comments, I was trying out things

I also thought that it will help to put an image next to unordered list, but that put my icon on top of the navbar

Hello Everyone!! Urgent help needed!!

Whenever I open localhost:8000 or 127.0.0:8000 it gets redirected to https://localhost:8000/ or https://127.0.0:8000/. It started happening after I added SECURE_SSL_REDIRECT = True in my settings.py (i am using django).

[inland oak]

that what SECURE_SSL_REDIRECT does ;b

it redirects from http to https

using just http is unsafe in production, we are supposed to use verified cerificates and only https mode

Over the past week the page I have been successfully scraping via AWS Lambda for 2 years made a change and is now sending a 403 response if you don't have cookies enabled ( javascript: var cookiesEnabled=(navigator.cookieEnabled)? true : false; ). Does anyone know a way around this? I believe I need to specify a user agent and somehow enable this, but that's only a guess. Any help is greatly appreciated!

[orchid olive]

also i have no documentation, php had a way to split session by user, but i have not find how to do the same in python-flask

can i use session["inventory"]["user"] ?

[limber flower]

Help!! me, I want to take an existing url from the web and make a backend for it, can I do it with django?

[warm igloo]

I think you need to do a little research on how hosting, domains, DNS, and some other things work. It's not a small topic to cover.

Roughly, yes you can host a site (frontend AND backend) in Django and you can point a domain at it. But you have to get it hosted. And have an IP to point your DNS to. And so forth and so on.

[warm igloo]

Sounds like you may also want to check that site's TOS (terms of service) to make sure you're even ALLOWED to be scraping them. And if you are not, we definitely cannot help you get around that.

[normal tulip]

understood, thanks.

[normal tulip]

it's proboards.com, free message board hosting, we use it in a fantasy sports league to keep track of certain things, and then I in turn post links to the threads in slack.

so nothing too critical or anything 🙂

[warm igloo]

right but their changes could be because they are trying to mess with bots by having that js check on cookies

[normal tulip]

understood, not trying to argue w/ you

[warm igloo]

oh I know, sorry if it is coming off harsh

[normal tulip]

in my googling i found people having this issue w/ cloudflare, and it looks like they are now using cloudflare 🙂

selenium/chromedriver looks to be the workaround, just gotta figure out how to do that in aws lambda now

[warm igloo]

I did look at their TOS and spidering/crawling/etc is forbidden. So best of luck as it sounds like you have a totally non-shitty bot (like a sneakerbot or whatevs) but yeah ... sorry. :/

[frosty lance]

Django or flask?

[olive patrol]

They’re both good, but Django is more popular

[native tide]

hello

i need help please

thats my codfe

[round plinth]

First off, is there any reason why you are using var instead of let / const ?

Second ...
```js
/* code here */
```

you can edit your message for the second part

[round plinth]

Third, I know that error.

// When you did this
progress.max = requiredclicks;
// The result of this (which wouild be outputted to the console) was actually false
console.log(Number.isFinite(requiredclicks));
// Put this last line before the `progress.max` assignment line
// or add that argument to the `console.log` that outputs `requiredclicks`

[native tide]

idk lol

[round plinth]

NaN, Number.POSITIVE_INFINITY, Number.NEGATIVE_INFINITY, or a non-number ... all would be invalid for that.

Also, the progress bar has a minimum of 1 ... I think ... lemme check

[native tide]

wym

[round plinth]

oh ... after testing <progress> tags default to a missing value attribute (the "indefinite" state) and also default to max being 1 (but it can be any finite number that is positive )

Somehow your program tried to set progress.max to a value which is not valid ....

[native tide]

oh

progress.max = requiredclicks;

[round plinth]

yeah.

[native tide]

how is requiredclicks not valid

[round plinth]

somewhere, requiredclicks was not a finite number.

[native tide]

what does finite mean xD

[round plinth]

finite means it is a number, and NOT one of these special values:

NaN // Not a Number
Number.POSITIVE_INFINITY // can get it by a huge calculation
Number.NEGATIVE_INFINITY // same as above but it is a negative number

You can get one of those easily if you divide by zero

[native tide]

okay ty

any idea how to fix it?

[round plinth]

what is your requiredclicks getting set to?

[native tide]

level * 250 + multiplier * 50

[round plinth]

Ah, I think I see why.
When you call loaddata() your localStorage might not have level set (or it was cleared), or the value you got is set to a non-number.

By the way, localStorage IIRC always returns a string if the value is set (I forgot if it returns null if the value is unset or not)

[native tide]

oh ok

so i should set level to local storage?

level = parseInt(localStorage.getItem("level"))

i have

[round plinth]

.... you probably should make a class to help hold the data in memory and let that update your localStorage for you

[native tide]

im quite bad with classes

im new to js

[round plinth]

Ah.

Lemme find the link

Note that The Coding Den may have had a recent issue with people being banned unfairly, and for me being one of them much earlier than I heard for that "purge" ... well ... I don't recommend going there.

[native tide]

do u know how to use classes

@round plinth

if u do do u think u can put that into a class for me

[round plinth]

I can do that, but it would be spoon feeding you the code.

[native tide]

alr

idk how to put it into a class

@round plinth

[native tide]

hi guys , how are you

[wind dove]

I have a mini project I'm working on and I setup a little flask site to interface it remotely and I left it on today (It's port forwarded) and I got these requests seemingly from nowhere:

I'm assuming this is some bot testing a security glitch on something like wordpress but anyone know any more info on it.

The end of the url I blocked out is Mozi.m+-O+/tmp/netgear;sh+netgear&curpath=/&currentsetting.htm=1

[native tide]

a cyber attack lol

where's your flask site deployed to?

perhaps this is something for the #cybersecurity channel to help with

[wind dove]

It's not an actual site just something I had so I could interface with that program that one day and alright thank you.

I was just home hosting it

[turbid horizon]

Is codeacedemy a good resource for learning flask?

[urban sleet]

For any web development related assignment kindly HMU .Quality and on time delivery assured.I can provide samples on request.Thanks

[native tide]

i'm also learning flask. I haven't used codeacademy for flask. However, I've been practicing with the documentation and docker. What's your developer experience like? e.g. absolute beginner

[turbid horizon]

I have basic experience in c++ and c# I know the basics of python but I just started python around a month and a half ago and I am starting to learn flask. So a beginner

[native tide]

I used the quick start guide https://flask.palletsprojects.com/en/2.0.x/quickstart/#
maybe this https://github.com/mjhea0/flaskr-tdd

[turbid horizon]

Thank you I will check it out

[native tide]

get comfortable with python first in my opinion. I'm doing this https://exercism.org/ @turbid horizon

[turbid horizon]

Ty that will definitely be helpful

[native tide]

good luck, i'm also learning. keep at it.

I've never worked with Web Auth before. I have a Flask site I'm putting together that allows OAuth "Sign in With X" only for logging in and I'm unsure what to do with their credentials when they sign in. Do I just take their Email Address and check for existing user and otherwise create it? Then for keeping logged in how does that work?

[golden ibex]

Actually I think I got it, I needed to utilize Flask-Login with Flask-Dance

hi is anyone here an app developer?

[dire fractal]

Loads of people

[native tide]

hello can anyone tell me how to publish a site using VS code?

have made i want to get a url and all and make it available for public use

[native tide]

deploy it on firebase

@native tide so you have like the html css and javascript files?

[native tide]

actually i just want to test the file is basically a hello world

what is firebase?

oh you are just starting

yes

um

okay there are alot of things to learn

you gotta learn how the internet works

things like hosting domain names etc

just google it or watch a video on youtube

um can you explain this in detail to me after half an hour

i have a school class

thanks

bro just google it or watch a youtube video

um ok

[gritty sage]

Hi friends, I am after a bit of help, im trying to scrape a table off a website, but i need to fill out a search bar before the table is shown, I want to figure it out for myself but not sure what to search up on google, what are these websites called?

eg copy paste the url into another browser (or python) and the table is reset and search terms need to be reloaded

[gritty sage]

I can copy paste the table but then need to convert to csv?

[limber flower]

Can you give a video or something about it?

[trim wolf]

Hey Everyone!! Urgent help needed!!

Whenever I try to login in my Website it gives a 403 Forbidden Error
The Message: CSRF verification failed. Request aborted.

But I have {% csrf_token %} in my login form
Also I am using Django!

Github Repo: https://github.com/Jonak-Adipta-Kalita/JAK-Website

[hoary yarrow]

can you make a website with only python or would you also need html

[inland oak]

U will also need html

[hoary yarrow]

crap

idk shit ab html

[inland oak]

I would say knowing some CSS is also preferable if u wish it looking good

[hoary yarrow]

i only know python sadly

still learning about it too

[inland oak]

There are CSS Frameworks for people brain-dead in it. bootstrap for example

As easiest and fastest solution

To have good looking site

[elder echo]

Hey everyone goodnight, so I've been specializing in the MERN stack but I don't really know any frameworks/libraries besides socket.io... What technologies would you guys recommend?

[lilac solar]

Are you wanting to branch out from the MERN stack? I am assuming so given your asking on the Python Discord?

[long monolith]

This guide with Flask and htmx seems very interesting: https://github.com/talkpython/htmx-python-course + https://github.com/rajasegar/awesome-htmx

[bright mason]

yes you would

[elder echo]

Yeah basically

I’ve heard development on django and flask is quick but it could be slow at times

how to link html front end with python backend?

i found this code on net:

<form name="search" action="/cgi-bin/test.py" method="get">
Search: <input type="text" name="searchbox">
<input type="submit" value="Submit">
</form> ```

but I dont know what is cgi

[native tide]

Presumably a resource on the site where this form is hosted. If the form is on a domain like example.com, /cgi-bin/test.py is going to be found at example.com/cgi-bin/test.py

[glad egret]

my form is stored locally

on my device

[native tide]

Do you have a folder locally cailled /cgi-bin?

[glad egret]

my backend name is fetcher.py stored in same folder as my html form

[native tide]

You should be able to set that location to fetcher.py then, but like the action field just sends the data as an http request to that "endpoint", and if it's a python file, I'm not sure how that will consume it

Where was that tutorial?

[glad egret]

stackoverflow

my question is will this work?

<....... action=".......\fetcher.py">```

instead of cgi?

[native tide]

It will not, since that is not something that accepts an http request

[glad egret]

by the way what is cgi?

[native tide]

You could use an http server on your backend? Something like flask or django or starlette

CGI is just the name of the folder for that specific problem

[glad egret]

nothing special?

[native tide]

Could you link that SO post?

[glad egret]

yes

https://stackoverflow.com/questions/15965646/posting-html-form-values-to-python-script

another query. Actually i wish to store the value written in my form.html to fetcher.py

[native tide]

Interesting, I think I was wrong then. CGI is another http framework

[glad egret]

will this cause a problem ? if i dont use cgi?

[native tide]

Both ... and its alternate name are improperly configured
Domain does not resolve to the GitHub Pages server. For more information, see Learn more (NotServedByPagesError). We recommend you add an A record pointed to our IP addresses, or an ALIAS record pointing to suiniee.github.io.
how do i fix this? i dont understand the error

[native tide]

Yes, just a python script on it's own won't accept an http request, but there are many frameworks to have an http server

Like mentioned before, http and cgi are builtin, but 3rd party frameworks provide more utilities

Those include flask, django, starlette, fastapi, etc

[glad egret]

then how to create a cgi-bin python file?

[native tide]

The cgi section on the python docs covers how to do it, but it's a bit involved

https://docs.python.org/3/library/cgi.html

[mighty iris]

@native tide, are you familiar with fastAPI?

[native tide]

Yeah I've used it before

[mighty iris]

Can I dm u?

for a short question

[native tide]

I prefer you ask here since others can correct me, and I'll be leaving soon

[mighty iris]

oh ok

how do i past python code here?

[native tide]

!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.

[native tide]

or if it's long

!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.pythondiscord.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.

[mighty iris]

• a POST request with a boolean parameter that returns the current date in yyyy-mm-dd hh:ii:ss format if the parameter is set to true and returns the date in yyyy-dd-mm format if the parameter is set to false
• a GET request that retrieves the value of a counter of the number of times either of the two endpoints was called

[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.

[mighty iris]

from typing import Optional
import threading
from fastapi import FastAPI
from datetime import datetime
app = FastAPI()

counter = 0
lock = threading.Lock()

@app.post("/fecha")
def mostrar_fecha(formato : bool): 

    global counter
    with lock:
        counter += 1

    if formato:
        fecha = datetime.today().strftime('%Y-%m-%d-%H:%M:%S')
    else:
        fecha = datetime.today().strftime('%Y-%m-%d')

    return {'Fecha':fecha}


@app.get("/counter/")
def count():
    global counter

    return {"Counter":counter}

Is that correct?

I mean, it works

but it's an important assignment, and wanna get full score

[native tide]

It looks fine yeah, but depending on how heavy the load to your server is, using that lock inside the function can slow things down

[regal fossil]

QUESTION
Django
When using django signals do we have to write each signal for each model?
for example if we have a models User, profile, Education, and has OneToOne Relation with Profile and Forignkey with Education so do we need to write signal for each of the model separately or only one signal for both?

[native tide]

I.E, if you get two requests at the same time, you have to process them synchronously because the lock is held by one request at a time

Now in this case, since the lock is only held for a fraction of a second, it's probably fine

[mighty iris]

I mean, this is a very simple project

Do you think the lock is necesary?

[native tide]

I don't know what your professor/teacher is looking for though

[glad egret]

python script uses import cgi is that sufficient

[mighty iris]

The server won't overload

[native tide]

Actually the lock may not be necessary since you aren't using an async function

[mighty iris]

yeah

I'll delete it

I haven't seen the lectures lol, I should

He just wanted us to learn basic backend stuff

Thanks for your help 🙂

[glad egret]

i need some help in cgi. has anyone used this before?

[native tide]

You still need to use cgi to get the form values. For instance:

import cgi
form = cgi.FieldStorage()
form.get(...)

[glad egret]

yes. my question is :

is writing import cgi sufficient to create a cgi-bin file? or I need to install some things too?

in simple words does the code sent by you sufficient to change a nomal .py file tocgi file?

[native tide]

Yes, but, you also need to put it somewhere specific

[glad egret]

also does a cgi file work if not stored in a cgi-bin file?

[native tide]

For instance, the SO post uses cgi-bin which is the default for linux

What OS are you using

[glad egret]

the documentation says that it works on servers only

i use Windows 10

[native tide]

So you can use it on windows 10, but the process is a bit involved. You have to install the CGI element.

https://docs.microsoft.com/en-us/iis/configuration/system.webserver/cgi
In the part where it's specifying how to install it, windows 10 uses the same instructions as windows 8, and everything from there on is the same as well

I've gotta run now, but I think that's the gist of it

[glad egret]

after installing the cgi element?

[native tide]

how can i connect my flask code to my domain?

[mortal pike]

in CSS?

[vestal hound]

what does the Python file do

[vestal hound]

you want to host your code somewhere

and then update DNS records to make your domain point to where you're hosting the code

[native tide]

I got it, thanks.

what abt a pygame based game?

[vestal hound]

the principle is fundamentally the same

your browser is (basically) incapable of running Python code

oof

[sly echo]

Hello

I've a query as I'm just a beginner

I have got command on basic Python like OOP, loops, functions, strings, variables, lists, data structures and algos.

I'm willing to learn Django now.

Do I need to learn HTML and CSS before I jump to Django?

[vestal hound]

not necessarily

BUT Django has a lot of magic in it

you might get kinda lost

[sly echo]

So how should I begin

I know about basic html though like what are simple tags and making a simple site with just head body and p tags lol

Is this much HTML enough?

[vestal hound]

uh

probably not

🥴

CSS is quite important

tbh

[sly echo]

So how should I begin?
with SQL or with HTML/CSS?

[vestal hound]

because it controls layout

[sly echo]

How much SQL do I need to learn?

People say you don't need much SQL to learn for Django unless you really need to dive into database engineering

My teacher said you need only 1 week of SQL practice and that's all.

is this a channel where i ask about selenium? or diff one

[limber flower]

How to retrieve post data from a custom form in django?

[native tide]

Is there a way i can learn about what {%%} and how to use it for reusing code

dm me

[wooden ruin]

you just need to know the basics of sql. in django you almost never write raw sql code, but it's important to understand how django does it and what-not

[wooden ruin]

request.POST inside of your view function should give you POST data assuming you sent a post request

[limber flower]

Hmm

[wooden ruin]

{% %} just allows you to use logic inside of your html before it is displayed to the user (template pre-processing)

[wooden ruin]

def my_view(request):
  if request.method == "POST":
    username = request.POST["username"]

like this

[limber flower]

it gave me a multivaluedictkeyerror

[wooden ruin]

the html input fields need a name attribute

that same name u use to access the value of it

[limber flower]

o ok

and 2 more things

if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            email = form.cleaned_data.get('mail')
            age = form.cleaned_data.get('age')
            password = form.cleaned_data.get('password')

            htmly = get_template('user/mainpage.html')
            d = { 'username': username }
            subject, from_email, to = 'Welcome!', '[e-mail]', email
            html_content = htmly.render(d)
            msg = EmailMultiAlternatives(subject, html_content, from_email, [to])
            msg.attach_alternative(html_content, "text/html")
            msg.send()

            messages.success(request, f'Your account has been created !')
            return redirect('login')
    else:

    return render(request, 'user/sign_up.html', {'form': form, 'title':'register here'})

i saw it used to reuse html

[limber flower]

This is a code. (I took it from a website)

In this code, where is the stuff being stored?
