why does any interaction with the django site direct you to the data addition form?
The task was given to develop a service for working with the restaurant database on django. Clicking on the corresponding buttons /fields of the data table should redirect to pages with edit/add/delete forms, but any interaction with the site redirects only to the page for adding new data. I've been trying to find the reason for this behavior for several hours, but nothing comes out. Below is the html markup of one of the pages, views, forms and URLs for working with one of the database tables. <body> {% include 'main/navbar.html' %} <h1>restaurants</h1> <div class="add"> <form method="post" action="{% url 'create_restaurant' %}"> {% csrf_token %} {{ form.as_p }} <button type="submit" class="btn btn-success">Добавить</button> </form> </div> <table class="table"> <ul></ul> <thead> <tr> <th>Address </th> <th>Phone number</th> <th>Delivery area</th> <th>Menu</th> <th></th> </tr> </thead> <tbody> {% for restaurant in restaurants %} <tr data-id="{{ restaurant.id }}"> <td class="editable-field" data-field="address">{{ restaurant.address }}</td> <td class="editable-field" data-field="phone">{{ restaurant.phone }}</td> <td class="editable-field" data-field="district">{{ restaurant.delivery_code.district }}</td> <td class="editable-field" data-field="menu">{{ restaurant.menu_code.name }}</td> <td> <button class="btn btn-danger" data-toggle="modal" data-target="#confirmDeleteModal{{ restaurant.id }}"> delete </button> <div class="modal" id="confirmDeleteModal{{ restaurant.id }}" tabindex="-1" role="dialog" aria-labelledby="confirmDeleteModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="confirmDeleteModalLabel">Confirmation of deletion</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div … -

Issue with requests from Nuxt.js not adding cookies to Django server
I'm working with a Nuxt.js frontend and a Django backend and encountering an issue where cookies are not being set correctly after JWT authentication. My Nuxt.js app is running on https://localhost:3000 and the Django server is on https://localhost:8000. Despite successful authentication using JWT tokens, when I make a request to the server, the cookies are not being attached. Checking the Network tab, I noticed that the client-side isn't sending cookies. Here's my Django settings related to CORS and cookies: # SECURITY WARNING: don't run with debug turned on in production! DEBUG = True ALLOWED_HOSTS = ['*'] CORS_ALLOWED_ORIGINS = [ "https://localhost:3000", ] # Other settings...

AJAX is only getting data from last form in loop (Django)
I have a for loop that creates a number of forms on the page. I want to be able to submit these forms to another page without refresh using AJAX, however no matter which form I submit it only ever shows the value for the very last form. HTML code {% for post in post_list %} <form class = "f_form" id="f_form" name = "myForm" method="POST"> {% csrf_token %} {{ form.as_p }} <button type="submit" class="add">Submit</button> </form> {% endfor %} Jquery <script type="text/javascript"> $(document).ready(function(){ $(document).on('click','.add',function (event) { event.preventDefault(); var element = $(this); $.ajax({ url: '{% url "webscraper-favorited" %}', method: 'post', data:element.parent('.f_form').serialize(), success: function(data){ $('#message').html(data); } }); return false; }); }); </script> views.py def favorited(request): if request.method == 'POST': favorited = request.POST.get('favorited') favorites.append(favorited) print(favorited) context = { 'favorites' : favorites, } return render(request, 'webscraper/favorited.html', context) Right now the script is outside of the for loop but I previously tried putting it in the for loop as well. Instead of binding the script to the submit button I also tried binding it to the form id. That yielded the same result from my attempts. -

RTCPeerConnection Issue: Uncaught DOMException - Failed to execute 'setRemoteDescription' on 'RTCPeerConnection Django
I am encountering an issue with my WebRTC implementation in Django using Django Channels. The error I am facing is: "Uncaught (in promise) DOMException: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote answer sdp: Called in wrong state: stable" After some research, I found a possible explanation for this error on Stack Overflow. It seems to be related to the fact that when a third user joins, it sends an offer to the two previously connected users, resulting in two answers. As a single RTCPeerConnection can only establish one peer-to-peer connection, attempting to setRemoteDescription on the second answer fails. The suggested solution is to instantiate a new RTCPeerConnection for every remote peer. However, I'm unsure how to implement this in my existing code. Below is the relevant portion of my consumers.py and JavaScript code. consumers.py and JavaScript code import json from typing import Text from django.contrib.auth import authenticate from Program.models import ChatRoom, Message from channels.generic.websocket import AsyncWebsocketConsumer from .service import add_remove_online_user, updateLocationList, add_remove_room_user from asgiref.sync import sync_to_async from channels.db import database_sync_to_async class ChatRoomConsumer(AsyncWebsocketConsumer): async def connect(self): self.room_name = self.scope['url_route']['kwargs']['room_code'] self.room_group_name = self.room_name print(self.room_group_name) await self.channel_layer.group_add( self.room_group_name, self.channel_name ) await self.accept() await self.authenticate_user() await self.channel_layer.group_send( self.room_group_name, { 'type' : … -

Serializing multiple inheritance models in Django REST Framework
I have this model structure: class Main (models.Model): name=models.Charfield(max_length=50) ... class Category (Main): type=models.Charfield(max_length=50) ... class SubCategory1(Category): charasteristic=models.Charfield(max_length=60) ... class SubCategory2(Category): charasteristic=models.Charfield(max_length=60) That is, there is one parent from which one children inherits, from which, in turn, multiple childrens inherit. For the API, I would like to show a complete structure in the json, from grandparent to every grandson. I mean, if I use the following serializer: class Subcategory1_serializer(serializers.ModelSerializer): class Meta: model=Subcategory1 fields=("__all__") it returns something like this: [ { "name": "type": "charasteristic": }, ] But this forces me to create a serializer for every single Subcategory. I want to get it in an automatic way. I've tried accessing via subclasses, I took a look at some proposals about Polymorphism (but I get lost) and I have tried to redefine inheritance in terms of OneToOne relationships, but I still cannot solve it (and it complicates data introduction from the admin panel). Any help would be great, Thanks in advance -
