Heroku release fails, error related to django.utils
So I updated my python code to Django 4.0 and with that, had to remove and update some deprecated code as "ungettext_lazy" and similar. Locally, the code is compiling well but when I push it to heroku, I get this error: from django.utils.translation import ungettext_lazy ImportError: cannot import name 'ungettext_lazy' from 'django.utils.translation' (/app/.heroku/python/lib/python3.9/site-packages/django/utils/translation/__init__.py) I've tried a few things but haven't been able to update this on heroku. -
Django rest framework ListApiView slow query
I have a displays table with 147 rows. I am not doing any heavy computation on this data set I just need to get it fast from the database. For now, the load time is 3-4 seconds.

How to connect redis heroku for websocket?
I'm making chat. I need to deploy my django app to heroku. I did it via the docker. I use free heroku redis and django-channels.

How to hash strings in python(django) and compare the hashed value with a given string
I'm working on a web app that allows users to sign up then login, I used the following functions to hash the password from passlib.hash import pbkdf2_sha256 import math def encrypt_password(pswd): encrypt_pswd = pbkdf2_sha256.encrypt(pswd, rounds=(int(math.pow(len(pswd),3))), salt_size=(len(pswd)*2)) return encrypt_pswd def verify_password(pswd, e_pswd): en_pswd = encrypt_password(pswd) if en_pswd == e_pswd: return True else: return False my problem is that the string I hashed doesn't produce the same result when I hash it for a second time. How can I resolve this issue or what methods can I use hash the password, store in the database and compare that value with the one from the login form -
Apache + mod_wsgi + Django + dataclasses stopped working after upgrade to python3.10
After upgrading to python3.10 code with dataclasses stopped working with mod_wsgi. If a class is created with @dataclass decorator (with just a single attribute x: str) and then instantiated somewhere in apps.py at module level, an exception is thrown. The reason is missing generated __init__ method (I confirmed that everything works if I define __init__ manually). Unfortunately, in real project it's part of external library and dataclass is instantiated in imported module, so there's no way to define __init__ by hands. The code without changes (all packages have same versions too) works with python3.9. To be clear, here's the code: # models.py from dataclasses import dataclass @dataclass class Test: foo: str # apps.py from django.apps import AppConfig from .models import Test Test('bar') # Error is thrown here class AppConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'app' It seems like there's a bug somewhere. I also know that mod_wsgi only support python up to 3.8, according to data on pypi, but can't believe the answer is "Look for other wsgi solution or don't upgrade yet" (if so - tell me too, it might be true). You might notice that Django is of version 3.2 in requirements while 4.0 is available: I tried … -
Django Wrong File Path / Redirect and Pass Data
I am struggling to get this right. I am trying to redirect from PageOne to PageTwo and while supplying PageTwo with selected data from PageOne. I have tried a few things and can't seem to get this right. Method 1 Changing File Path class PageOne(TemplateView): template_name = 'home/pageone.html' def get(self, request): args = {} return render(request, self.template_name, args) def post(self, request, *args, **kwargs): if request.POST.get('confirm'): name = request.POST.get('hidden_get_client_name') data= request.POST.get('get_data') args = {'name':name,'data':data} new_template_name = 'home/PageTwo.html' return render(request, new_template_name, args) This works, but the file path is still /PageOne when the page loads. How do I change this to PageTwo? Method 2 Redirect response = redirect('/PageTwo/') return response Using this method, the file path is correct, but I am unable to pass data? Any help would be greatly appreciated. I am struggling to effectively redirect between pages while passing data. -

"You need to enable JavaScript to run this app"; response is html instead of json
Technologies used: Django, Djoser, react.js, webpack I made the request in react.js: const config = { headers: { "Content-Type": "application/json", }, }; const body = JSON.stringify({ email, first_name, last_name, password, re_password, }); const response = await axios.post( `http://127.0.0.1:8000/auth/users/`, body, config ) I used Djoser in the backend to handle the auth requests. I console.log the response and find that the response is html instead of JSON. The status is 200 but it should be HTTP_201_CREATED based on Djoser's documentation. I checked that Djoser is in INSTALLED_APPS in Django and I have djoser==2.1.0. I try to add "proxy": "http://127.0.0.1:8000", in package.json, not working. I also try to use fetch instead of axios, also not working. I am not sure where the problem comes from. -

Why am i getting server 500 error in Django?
I have been trying to use the Django template inheritance feature for my project Since I've added {% block content %}s I am now getting a server error 500 whenever I try to run the child template. The base template runs fine. I am quite sure it has something to do with the content blocks, but I'm not sure why as I don't repeat any names of blocks and everything on the child template is contained within a block. Code goes like this: Base.html <!DOCTYPE html> <style> 'My style' </style> <html lang='en'> <head> <meta charset='UTF-8' {% block title %} webpage {% endblock %} <script>'Jquery reference'</script> </head> {% block script %} 'empty' {% endblock %} <body> <div id='navbar'> 'My navbar' </div> <div id='main_content_block'> {% block content %} <h1>This is my base</h1> {% endblock %} </div> </body> </html> Home.html {% extends 'main/base.html' %} {% block title %} <title>Home</title> {% endblock %} {% block script %} 'My javascript' {% endblock %} {% block content %} 'My content' {% endblock %} Thanks for your time -

Integrate python-social-auth to drf-spectacular (Swagger)
I have a Django (DRF) project with OAuth2 based on python-social-auth and Swagger based on drf-spectacular. I need to integrate these two libraries together so that Swagger allow OAuth2 authorization, for example Google OAuth2. I found OAuth2 configuration for drf-spectacular in settings: SPECTACULAR_SETTINGS = { ... 'SWAGGER_UI_OAUTH2_CONFIG': { ... # Oauth2 related settings. used for example by django-oauth2-toolkit. # https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#oauth-flows-object 'OAUTH2_FLOWS': [], 'OAUTH2_AUTHORIZATION_URL': None, 'OAUTH2_TOKEN_URL': None, 'OAUTH2_REFRESH_URL': None, 'OAUTH2_SCOPES': None, }, ... } But I'm not really sure whether it fits me or not. I wrote this in my version of this config, but it appearently has no effect: 'SWAGGER_UI_OAUTH2_CONFIG': { 'OAUTH2_AUTHORIZATION_URL': 'https://accounts.google.com/o/oauth2/auth', 'OAUTH2_TOKEN_URL': 'https://accounts.google.com/o/oauth2/token', 'OAUTH2_SCOPES': ['openid', 'email', 'profile'], } Swagger still has no OAuth2. Any idea how to manage it? -
how to submit a form and display output without refreshing
I'm trying to create a simple calculator which gets an input number from the user and shows the calculated output below it. The code works fine but it redirects and reloads the page, obviously. I don't want that I want the output to be displayed as soon as the user fills the form. I have 0 knowledge of js and ajax so I would appreciate you guys helping me with that part. I searched a lot but couldn't understand what to do. this is my form: <form id="myform" method="POST"> {% csrf_token %} Enter first number: <input type="text" name="num1"><br><br> <input type="submit"> </form> and this is the output bellow the form I want: <h1>congrats!</h1> as simple as that. fill the form, submit and display a simple message without refreshing
