Query only specific subclass(es) of an abstract superclass
This question is fundamentally similar to these previous questions: Django access to subclasses items from abstract class How to query abstract-class-based objects in Django? I am posting this as a new, separate question because: I have minor additional considerations that aren't addressed in the previous questions The previous questions are relatively old, and if it's the case that the correct answer has changed in recent times, I wonder if maybe those questions haven't been visible enough (given that they have accepted answers) to get the attention of those who might know about such potential changes. With that in mind, I'll take the question from the top and define it fully and concretely - and I leave it to the hive to determine if a close-duplicate is in order. Background Say I am constructing models to represent parts of a building. I split the building into logical classes: Floor BuildingSpace(ABC) Office(BuildingSpace) CommonArea(BuildingSpace) Goal Under Floor, I want methods that can retrieve all buildingspaces - or, either of its two subclasses separately: from typing import Type class Floor(models.Model): def getAllSpaces(): # return all objects that satisfy Type[BuildingSpace] def getAllOffices(): # return all objects that satisfy strictly and only Type[Office] def getAllCommonAreas(): # … -

Bad Request (400) in django web app in Azure App service while adding Custom Domain
In the Azure app service my Website is working fine with something.azurewebsites.net with the following code ALLOWED_HOSTS = [os.environ['WEBSITE_HOSTNAME']] if 'WEBSITE_HOSTNAME' in os.environ else [] But while adding a custom domain, it is showing as Bad Request (400). I think the problem relies on the Allowed host, and the Django app is not allowing my custom domain. I couldn't find a solution or a perfect line of code to resolve this issue. -
Does MongoEngine have an "AutoField()" like Django?

How Can I Check For The Existence of a UUID
I am trying to check for the existence of a UUID as a primary key in my Django environment...and when it exists...my code works fine...But if it's not present I get a "" is not a Valid UUID... Here's my code.... uuid_exists = Book.objects.filter(id=self.object.author_pk,is_active="True").first() I've tried other variations of this with .exists() or .all()...but I keep getting the ['“” is not a valid UUID.'] error. I did come up with a workaround.... if self.object.author_pk is not '': book_exists = Book.objects.filter(id=self.object.author_pk,is_active="True").first() context['author_exists'] = author_exists Is this the best way to do this? I was hoping to be able to use a straight filter...without clarifying logic....But I've worked all afternoon and can't seem to come up with anything better. Thanks in advance for any feedback or comments. -
Django Channels: Channel Name type error appears when loading web socket chat
I'm building a basic websocket live chat using Django Channels and while the site loads fine, when I enter into the site, in my terminal I get this TypeError Message: TypeError: Channel name must be a valid unicode string with length < 100 containing only ASCII alphanumerics, hyphens, underscores, or periods, not RedisChannelLayer(hosts=[{'host': '127.0.0.1', 'port': 6379}]) Im assuming the problem lies in my settings.py file but based on my current channel layer settings, I don't see what the problem is: CHANNEL_LAYERS = { 'default': { "BACKEND": 'channels_redis.core.RedisChannelLayer', "CONFIG": { "hosts": [('127.0.0.1', 6379)], }, }, } I'm new to django and channels so maybe theres a place where I defined the channel name and i'm just missing but I'm not sure or where to look for it if thats true. -

Django - Save form fields while paging
This will be a lengthy post, please have patience with me, I just started with Django and try to wrap my head around it. I created a site that will go thru exam questions one at a time, displaying the question and the multiple choice answers like on countless other websites. The challenge I experience is when the user clicks "NEXT" on the pagination buttons, I would like for the selected answer(option) to be saved back to the database. I tried it with AJAX scripts but the view never got executed. Maybe there is a better way to do this or could you please point me into the right direction? I will post all of my code and hope someone can please assist me. Thank you for taking the time to look at this. I start with the models.py: from django.db import models class QuesModel(models.Model): question = models.TextField(null=True) code_snippet = models.TextField(null=True) op1 = models.CharField(max_length=200,null=True) op2 = models.CharField(max_length=200,null=True) op3 = models.CharField(max_length=200,null=True) op4 = models.CharField(max_length=200,null=True) ans = models.CharField(max_length=200,null=True) def __str__(self): return self.question class Answer(models.Model): ans_id = models.AutoField(primary_key=True) question_id = models.ForeignKey(QuesModel, on_delete=models.CASCADE) fname = models.CharField(max_length=50) lname = models.CharField(max_length=50) examdate = models.DateField(auto_now_add =True) answer = models.PositiveSmallIntegerField() def __int__(self): return QuesModel.question[self.question_id] template is home.html: {% … -

Request Errors with fetch API
I'm trying to send data through a form with just one field to my Django API, then read and use the data received in the API for other things. I don't want to store the data, just use it. This is my react code: const handleSubmit = async (e) => { e.preventDefault(); try{ let res = await fetch(api,{ method: 'POST', headers: {'Content-Type':'application/json'}, body: { url: url, }, }); let resJson = await res.json(); if(res.status === 200){ console.log(resJson) setUrl(""); setMessage("Success"); } else{ setMessage("Error"); } }catch(err){ console.log(err); } }; This is my Django view.py @api_view(['POST']) def eda(request): response = { 'result': 'lalala', 'url':request.POST['body'], 'code': 'success' } return Response(response) I don't understand what's wrong, but I get bad request error or unsupported media type error. -
Using a custom model for Django Admin
I have a custom user model, which an admin model inherits: class User(AbstractBaseUser, PermissionsMixin): ... class Staff(User): is_staff = models.BooleanField( _("staff status"), default=True, help_text=_("Designates whether the user is staff"), ) ... class Admin(Staff): is_admin = models.BooleanField( _("staff status"), default=True, help_text=_("Designates whether the user can log into this admin site."), ) ... As well as a custom backend for authorization class AdminBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): if username is None: username = kwargs.get(Admin.USERNAME_FIELD) if username is None or password is None: return try: user = Admin._default_manager.get_by_natural_key(username) except Admin.DoesNotExist: # Run the default password hasher once to reduce the timing # difference between an existing and a nonexistent user (#20760). Admin().set_password(password) else: if user.check_password(password) and self.user_can_authenticate(user): return user ... However, I am unable to log in due to has_permission in admin/sites.py Is there a way to avoid registering a custom site, as that will increase complexity? -
Django : Getting the image URL of elements in a table that has a many-to-one relationship with another table

Handle divide by zero with aggregated fields in Annotate expression

DRF Grant Type Convert Token
I'm trying to implement an authentication system in my Django backend through the Oauth2 protocol. Also, I'm using the drf_social_oauth2 lib. However, I'm having a hard time understanding how I can reproduce the auth system in Postman. Postman offers some auth flows (Grant Types) which greatly facilitates the authentication process. However I came across an authentication flow I've never heard of ( convert_token ). I wish to use the oauth2 system to authenticate using the Facebook Provider, but its not clear for me the flow to validate this in Postman. this is the snippet of code send to validate the access token in react: import axios from 'axios'; import { useHistory } from 'react-router-dom'; const facebookLogin = (accesstoken) => { console.log(accesstoken); axios .post('http://127.0.0.1:8000/auth/convert-token', { token: accesstoken, backend: 'facebook', grant_type: 'convert_token', client_id: '05GYopkyMDxFakgCSuNtpOLrNcyJwU054wZfYBt1', client_secret: 'U3r3rmtff7t52Xa1chfzGf5vtl06zr4PwGbi8sWBcilTKs0YJEm278JPmXbcgMsyYpxYMQbDKFsyjhrzKwDLW8VMfW0ePZmrRuSmssnFPvqjeodYsNTfObTAzxOxZKuH', }) .then((res) => { localStorage.setItem('access_token', res.data.access_token); localStorage.setItem('refresh_token', res.data.refresh_token); }); }; export default facebookLogin; I am expecting to do the same into Postman -

Fitting rows and columns in the same table so they line up nicely
I would like to use two different <thead>'s in the same table but i want them stacked nicely. The way it is now, the first heading has 1 less column then the 2nd one so it looks funky. If there is a way to expand that first heading out so that there isnt a space to the right of it, that would be great. Or maybe you know of a better way of tackling this problem. Here is how the table looks right now. and here is the code that i am using to get this result <div class="hidden" id="part-req-section"> <form method="post" name="partForm" id="partForm"> {% csrf_token %} <div class="row"> <div class="container"> <div class="row"> <div class="container"> <div class="table-responsive"> <h3>Part Request</h3> <table class="table table-bordered table-hover table-responsive"> <thead> <tr> <th scope="col">Part name*</th> <th scope="col">Quantity*</th> <th scope="col">Reason*</th><br> </tr> </thead> <tbody id="part-req-form-list"> {{ part_request_formset.management_form }} {% for some_form in part_request_formset %} <tr id="part-req-form" class=""> <td>{{ some_form.part|as_crispy_field }}</td> <td>{{ some_form.quantity|as_crispy_field }}</td> <td>{{ some_form.reason|as_crispy_field }}</td> <tr> {% endfor %} <thead> <tr> <th scope="col">Aisle*</th> <th scope="col">Column*</th> <th scope="col">Shelf*</th> <th scope="col">Bin*</th> </tr> </thead> <tr> <td>{{ location.aisle|as_crispy_field }}</td> <td>{{ location.column|as_crispy_field }}</td> <td>{{ location.shelf|as_crispy_field }}</td> <td>{{ location.bin|as_crispy_field }}</td> </tr> <tr id="empty-part-req-form" class="hidden"> <td>{{ part_request_formset.empty_form.part|as_crispy_field }}</td> <td>{{ part_request_formset.empty_form.quantity|as_crispy_field }}</td> <td>{{ part_request_formset.empty_form.reason|as_crispy_field }}</td> … -
Nextjs With Django Content Security Policy (CSP)
In a project where Nextjs is used as a frontend and Django is used as a backend api, where should the Content Security Policy (CSP) be set?

Not sure if this matters but I am not using the api features in Nextjs, only django as an api. -

Here is my consumers.py: class ChatConsumer(SyncConsumer): def websocket_connect(self, event): me = self.scope\['user'\] other_username = self.scope\['url_route'\]\['kwargs'\]\['username'\] other_user = User.objects.get(username=other_username) self.thread_obj = Thread.objects.get_or_create_personal_thread(me, other_user) self.room_name = f'presonal_thread\_{self.thread_obj.id}' async_to_sync(self.channel_layer.group_add)(self.room_name, self.channel_name) self.send({ 'type': 'websocket.accept' }) print(f'\[{self.channel_name}\] - You are connected') def websocket_receive(self, event): print(f'[{self.channel_name}] - Recieved message - {event["text"]}') msg = json.dumps({ 'text': event.get('text'), 'username': self.scope['user'].username }) self.store_message(event.get('text')) async_to_sync(self.channel_layer.group_send)( self.room_name, { 'type': 'websocket.message', 'text': msg } ) def websocket_message(self, event): print(f'[{self.channel_name}] - Message sent - {event["text"]}') self.send({ 'type': 'websocket.send', 'text': event.get('text') }) def websocket_disconnect(self, event): print(f'[{self.channel_name}] - Disonnected') async_to_sync(self.channel_layer.group_discard)(self.room_name, self.channel_name) def store_message(self, text): Message.objects.create( thread = self.thread_obj, sender = self.scope['user'], text = text ) class EchoConsumer(SyncConsumer): def websocket_connect(self, event): self.room_name = 'broadcast' self.send({ 'type': 'websocket.accept' }) async_to_sync(self.channel_layer.group_add)(self.room_name, self.channel_name) print(f'\[{self.channel_name}\] - You are connected') def websocket_receive(self, event): print(f'[{self.channel_name}] - Recieved message - {event["text"]}') async_to_sync(self.channel_layer.group_send)( self.room_name, { 'type': 'websocket.message', 'text': … -
Django + AJAX comments
I'm trying to implement a comment system without reloading the page, but it doesn't work. Comments are inserted only after the page is reloaded, but AJAX does not work. <!-- COMMENT --> <div class="comment-section"> <form action="{% url 'love:comment_urls' %}" method="POST" class='comment-form'> {% csrf_token %} <input type="hidden" name="post_id" value={{i.pk}}> {{ comment_form }} <button type="submit" name="submit_c_form"> Опубликовать </button> </form> </div> <hr> <div class="comment_set"> {% if i.quotes_comment.all %} {% for com in i.quotes_comment.all %} <b>{{ com.user }}:</b> {{ com.body }} {% endfor %} {% endif %} </div> </div> JS code // COMMENT $(document).ready(function () { $('.comment-form').submit(function () { event.preventDefault(); console.log($(this).serialize()); var url = $(this).attr('action') $.ajax({ type: 'POST', url: url, data: $(this).serialize(), dataType: 'html', success: function (response) { console.log('Заработало') $('.comment-section').html(response['form']); }, error: function (rs, error) { console.log(rs, error) } }) }) }) As I said, comments are inserted only after a reboot, but when I click publish, nothing happens. If you change the dataType to 'json', the parser error pops up. Can you explain what I'm doing wrong? -
