How to access websocket from another function in another file
I'm trying to make a login page, and I want to access the websocket I've opened up. I'm assuming although I could be wrong, that you only want one websocket open at a time so I'm trying to use the one from earlier. But I'm having trouble accessing it. This is my main file that hosts what I have so far import React, { Component, useState, useEffect } from 'react'; import { render } from 'react-dom' import WebSocketStuff from './websocket'; import Navbar from './navbar'; import Login from './login'; import { BrowserRouter as Router, Switch, Route, Link, Redirect } from "react-router-dom"; function App() { return ( <div> <Navbar /> <WebSocketStuff /> <Router> <Switch> <Route path="/account/login" component={Login}></Route> </Switch> </Router> </div> ); } const appDiv = document.getElementById("app"); render(<App />, appDiv); This is the javascript file that has the websocket code. import React, { Component, useState, useEffect } from 'react'; export default function WebSocketStuff(props) { const [name, setName] = useState(''); console.log(window.location) var loc = window.location var socket; useEffect(() => { var wsStart = 'ws://' if (loc.protocol == 'https:') { wsStart = 'wss://' } var endpoint = wsStart + loc.host + loc.pathname; socket = new WebSocket(endpoint); console.log(socket); socket.onmessage = function (e) { console.log("message", e) setName(e.data); … -

How do I make changes to my Django HTML view file that extends a base template?
I have a Django test project that I am working on, and have been working on it for hours now, and I am stuck. I can't add other html syntax into my html file that extends a base template into it. I have a base template that works on my html view, however, when I make changes inside the html view, it doesn't reflect. Looks like I am missing something between the HTML view, and the base template. Below is the HTML view <!DOCTYPE html> {% extends "base.html" %} <!--https://www.anwita-arun.in/ --> {% block head %} <html lang="en"> <head> <title>Test Project</title> </head> {% endblock %} {% block body %} <body> <h1 style="font-size: 250px"> Testing </h1> <p> aloha </p> <form method="POST"> <!-- Form creation with post.

How to link my Django form selection to filtered database values
I am configuring a web page using Django in which I would like my form's dropdown options to filter the database options based on master ID. There are four options: allElements, oldElements, newElements, and testElements. My problem is that while I can create a for loop to iterate through the database based on any of the four variables I've defined, my form selection is not linked to the choices like I thought it would be.

Django - Run all tests inside of "test" sub-folder
So I've been running tests using the command python manage.py test to run every test inside the test folder and I'd like to run all test in a subfolder of the test folder. So I tried python manage.py test <app name>.test.<sub-folder>(path to the test sub-folder), but it doesn't work. I created an __init__.py file inside <sub-folder> that imports all the test files in <sub-folder>, but that didn't work. Every time I run python manage.py test <app name>.test.<sub-folder> the terminal outputs Run 0 tests in Xs. How do you run all tests inside of a sub-folder of the test folder in Django? -

How do I write a Django query to get distinct objects linked to another object?

Is there any way to write a query to get the Account objects such that they are already hydrated as actual objects? -
Django - What happens when you delete an entity in a table that has a foreign key ManyToMany relationship to another?
I've noticed that Django doesn't let you set the on_delete parameter for ManyToManyField. This made me curious what happens if you delete an entity in a ManyToMany relationship? So for example, let's say we have Book, which has a ManyToMany relationship to Author. Let's say that a book A has 3 authors: "Tom Lam", "Lam Tom" and "Britney Britney". Then let's say "Britney Britney" gets deleted from the Author table. Does "Britney Britney" get removed from the ManyToMany relationship with Book? Does an exception get thrown when trying to delete "Britney Britney?" What does Django do in the case that an entity is deleted when it exists in a ManyToMany relationship? -
Django-allauth: Redirect users post sign-up/sing-in to a specific page depending on the page they are coming from
Problem I have an invite system in my django app that allow users to invite other people (using their email) to join their team. When an invited user clicks on an invitation, they are redirected to an url that carries informations about the specific team the user was invited to. Such url calls a view called accept_invitation that handles the following use-cases: a) If a user is logged-in already AND they are also the invited user (i check the email of the invite), I add the user to the team and redirect them to the team's page. b) If a user is logged-in already BUT they are not the invited user, I redirect them to a page where I invite them to log-in with a different account. c) If a user is logged-out, I redirect them to a page where I invite them to log-in and/or sign-up to continue. Use-case a) works just fine but use-case b) and c) I had to figure out how to propagate the informations of the invite to the following screens and past the login. My initial idea was to add the parameters of the invitation to the request.session so that after the login-in I … -
Fix Django "Unresolved attribute reference" for prefetched field
Let's say I have the following Django models: class Toolbox(models.Model): name = models.CharField(max_length=255) tools = models.ManyToManyField("Tool") class Tool(models.Model): class Size(models.TextChoices): SMALL = "S" MEDIUM = "M" LARGE = "L" name = models.CharField(max_length=255) size = models.CharField(max_length=10, choices=Size.choices) I have a function to get all small tools for each toolbox. The @queries_disabled() comes from django-zen-queries to ensure the small tools have been prefetched and avoid N+1 performance problems. @queries_disabled() def get_toolbox_to_small_tools_mappings(toolboxes: list[Toolbox]) -> dict: return {toolbox: toolbox.small_tools for toolbox in toolboxes} The problem is my editor (PyCharm) is highlighting a warning: Unresolved attribute reference 'small_tools' for class 'Toolbox' I can fix this my changing the argument's type hint: def get_toolbox_to_small_tools_mappings(toolboxes: list[Toolbox] | QuerySet): ...

In Django how I can create automatically a many to many entry based on a field found in two models
I have the following models example: class TestSet(models.Model): name = models.CharField(max_length=50) def __str__(self): return self.name class Class(models.Model): name = models.CharField(max_length=50) test_set_id = models.ForeignKey(TestSet) def __str__(self): return self.name class Test(models.Model): title = models.CharField(max_length=50) test_set_id = models.ForeignKey(TestSet) def __str__(self): return self.title class ClassTest(models.Model): class_id = models.ForeignKey(Class) test_id = models.ForeignKey(TestSet) memo = models.CharField(max_length=250) def __str__(self): return self.memo What I want to do is when a new Class or Test is created, it should also create automatically a ClassTest entry if their test_set_id matches with the currenct entries on the database. Example: Lets say I already have three Test objects with test_set_id = 1 I create a new Class object with test_set_id = 1 After creating the new Class object, the program should also create 3 new entries in the ClassTest model connecting classes to tests based on the match of the test_set_id field. It should work the same if a new Test object is added. -
how to compare two querysets in django
I'm writing an if statement in Django that compares two querysets and extracts the same assignment. Although the results of cycle_per_day and next_visit_per_day are different, the field values are the same because the same Class Model is used. The assignment_id field is also included in both querysets. In other words, I would like to add a condition called if next_visit_per_day query reset exists in the cycle_per_day query set. But it doesn't apply. What went wrong? cycle_per_day = cycle_visit.filter(dosing_date__day=day, dosing_date__year=self.year, dosing_date__month=self.month, assignment__teacher=self.user.first_name) next_visit_per_day = next_visit.filter(next_visit__day=day, next_visit__year=self.year, next_visit__month=self.month, assignment__teacher=self.user.first_name) d = '' for cycle_visit in cycle_per_day: d += f'{cycle_visit.get_html_url_cycle}' for next_visit in next_visit_per_day: if next_visit.assignment_id in cycle_per_day: d += f'{next_visit.get_html_url_drop}' else: d += f'{next_visit.get_html_url_next_visit}' -

django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later is required (found 3.7.17) for Python venv
I'm having trouble setting up my database on Django. I am running my server on CentOS7 and although I downloaded the version of SQLite I wanted to use, Python keeps pointing to the preinstalled version that is not compatible with my version of Django. I've looked through the other questions that had the same problem as me: django can't find new sqlite version? (SQLite 3.8.3 or later is required (found 3.7.17)) How to use the latest sqlite3 version in python https://number1.co.za/upgrading-sqlite-on-centos-to-3-8-3-or-later/ But the thing that differs between all of these problems and mine is that I used the Python Manager that comes with aaPanel to install my version of Python (3.8.3) which creates a virtual environment for the version of Python that I'm using whereas the others download and compile it from the source. I have tried finding where the correct configure file (as I have found multiple that were not helpful) that is outlined in each of the answers to these questions could be, but to no avail. How could I go about pointing my version of Python to the up-to-date version of SQLite that I have installed? -

Usually I require user to be authenticated but in the case of GET action (both list and retrieve) I would like everyone to be able to access it with no authentication required. The code for this functionality is very simple: class GetUserViewSet(viewsets.GenericViewSet, mixins.ListModelMixin, mixins.RetrieveModelMixin): # allowed for everyone serializer_class = UserSerializer permission_classes = [permissions.AllowAny] queryset = User.objects.all() The permissions are set to allow any but there is probably some inconsistency with default auth class in Settings.py # --------------------------REST-framework-------------------------- REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticatedOrReadOnly' ], "DEFAULT_AUTHENTICATION_CLASSES": ( "rest_framework_simplejwt.authentication.JWTAuthentication", ), 'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema', } The last thing that could matter are my endpoints: urlpatterns = [ path("", UserViewSet.as_view({"post": "create"}), kwargs={'quantity': 1}), path("<int:quantity>/", UserViewSet.as_view({"post": "create"})), path("", GetUserViewSet.as_view({"get": "list"})), path("<int:pk>/", GetUserViewSet.as_view({"get": "retrieve"})), path("<int:pk>/", UserViewSet.as_view({"put": "update", "delete": "destroy"})), ] What I don't understand is that in other app where I have register functionality there is no such an error. I will show you this viewset: class ApiUserViewSet(viewsets.GenericViewSet, mixins.CreateModelMixin): serializer_class = ApiUserSerializer permission_classes = [permissions.AllowAny] queryset = ApiUser.objects.all() @extend_schema(request=ApiUserSerializer, responses=TokenSerializer) def create(self, request, *args, **kwargs): api_user_serializer = self.get_serializer(data=request.data) api_user_serializer.is_valid(raise_exception=True) api_user = api_user_serializer.save() refresh = RefreshToken.for_user(api_user) token_serializer = TokenSerializer( data={ "access": str(refresh.access_token), "refresh": str(refresh) } ) … -
Django-allauth: My post-sign-up redirect flow with Google Auth is broken and I can't figure out why
I integrated django-allauth with my Django app but something is not fully working: Problem If a user that does not have an account in my DB tries to sign-up using the the google allauth process, after the authentication process it is sent to the home page (behind login filter) successfully. However, if a user that already has an account in my DB (manually created) tries to login using the google auth by visiting /accounts/google/login/, after the authentication process it is sent to /accounts/social/signup/ (a weird page that django-allauth has). Funny enough thought, the user is logged in and if they try to access the home page they can and everything works. So it's just the redirect that is broken. I narrowed it down to the fact that the user's email already exist BUT there is no social account associated. Setup I have a custom user model where email is the main unique id of a user. from django.contrib.auth.base_user import BaseUserManager from django.db import models from django.contrib.auth.models import AbstractUser from django.utils.translation import ugettext_lazy as _ class CustomUserManager(BaseUserManager): """ Custom user model manager where email is the unique identifiers for authentication instead of usernames. """ def create_user(self, email, password, **extra_fields): """ Create … -
Django Heroku Porting
Trying to set up Django configurations for a public url. So I ran this first. $ echo "web: python manage.py runserver 0.0.0.0:\$PORT" > Procfile $ git add Procfile $ git commit -m "Specify the command to run your project" In Procfile: web: python manage.py runserver 0.0.0.0:\$PORT release: python manage.py migrate In settings.py: PORT = os.getenv("PORT", default="5000") # SECURITY WARNING: don't run with debug turned on in production!

Django FileField auto urlencoding problem
image_file = models.FileField(storage=s3, max_length=512, blank=True) I have a model with theis image_file field backed by s3 storage. The only problem I have with this field is if the filename contains any url-encode-able characters, it will auto encode the filename. For example, if the filename contains %40, when retrieve the value from the model, it becomes %2540. I wonder if there is a switch I can turn this feature/bug off.
