Best way to specify dedicated sub domain for authentication views in Django Rest Framework
I'm building and API using DRF and will be using it with a React SPA. I've chosen session authentication for my project because of the following reasons: It's built-in to DRF, so no dependence on 3rd party developers (a lot of auth packages or their dependencies are not maintained) CSRF + Cookie protection Ability to use Secure and HTTPOnly cookies However, I'm aware that it's recommended that we use Django's authentication views for the authentication pages and the single page app for the post authentication API calls. In this scenario, there are some views (i.e. Login, Logout, Password Reset, Register) for which the server responds with HTML and the rest return JSON. I would like to use different subdomain for these views i.e. different subdomain for HTML views and different subdomain for the JSON views. I'm a Django newbie and would really appreciate some suggestions on the best way to handle the separation of subdomains. I have some idea that the few ways I could achieve this are: using django-hosts using django sites (although I'm not sure if the cookie made by one site, would work on the other) point 2 domains to my server and handle the separation bit … -
django project always trying (and failing) to load file in separate app
I'm going back to an old django project and am trying to make a new site in a new app I just made, popularify. I want to load an httpResponse and nothing else when I go to the /popularify path , but it keeps trying and failing to get a favicon.ico file, the 404 error always appears in the chrome web console and django logs. I have it set up correctly so my popularify page loads a basic httpResponse: my main urls.py file in my project folder has a path: path('popularify/', include('popularify.urls')), The popularify app urls.py file looks like this: from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), ] And the popularify views.py file looks like this from django.shortcuts import render from django.http import HttpResponse def index(request): return HttpResponse("Hello, world. You're at the polls index.") All very basic to just load some text, but in console I am getting a unrelated 404 error trying to load a file I never directly specified, and dont want to load: If I click the favicon.ico link it shows the html file _base.html I have in my templates folder, a file I use as a base file in … -
How do I accept the friend request in django after sending a hyperlink in mail which redirects the user to accept/reject page?

How to work with drf-extension (Django Rest Framework) if the model has lookup_fields assigned
It would be better if I give an example that I was working on. The Models are class Author(models.Model): id = models.IntegerField(db_column='a_id', primary_key=True) first_name = models.CharField(max_length=20) last_name = models.CharField(max_length=20) class Book(models.Model): id = models.IntegerField(db_column='b_id', primary_key=True) title = models.CharField(max_length=60) author = models.ForeignKey(Author, on_delete=models.CASCADE) And the Serializers are, class AuthorSerializer(ModelSerializer): class Meta: model = Author fields = ('id', 'first_name', 'last_name') class BookSerializer(ModelSerializer): class Meta: model = Book fields = ('id', 'author', 'title') And the view sets are, class AuthorViewSet(NestedViewSetMixin, ModelViewSet): serializer_class = AuthorSerializer queryset = Author.objects.all() class BookViewSet(NestedViewSetMixin, ModelViewSet): serializer_class = BookSerializer queryset = Book.objects.all() Now The following APIs are working okay, /authors/ /authors/{author_id}/ /authors/{author_id}/books/ However, If I change the Author Views to class AuthorViewSet(NestedViewSetMixin, ModelViewSet): serializer_class = AuthorSerializer queryset = Author.objects.all() lookup_field = 'first_name' Then, the following APIs work /authors/ /authors/{author_first_name}/ But the following doesn't work. /authors/{author_first_name}/books/ I understand that it's because of the Foreign key relations between these two tables. I was just wondering whether there is any workaround if I want to keep the lookup_fields. Thanks -

How to pass data from Django template (after submission) to DRF API without using a model?
I have a form in my template which allows a user to upload an image. Once the image is uploaded and submitted, it gets stored in a specified directory (not 'media'). Note: The image is not stored in a Django model since I didn't create one (don't need it). After doing so, I need to create an API using the Django Rest Framework. When calling the API URL, I intend to display that stored image name. The result will look like this: {"image_name" : <'stored_image_name_after_form_submission'>} This is what I had done so far: views.py: from rest_framework.views import APIView #code for uploading an image def upload(request): if (request.method == 'POST'): uploaded_file = request.FILES['image'] fs = FileSystemStorage(location=settings.PRIVATE_STORAGE_ROOT) image_path = fs.save(uploaded_file.name, uploaded_file) #name of the image file messages.success(request, 'Uploaded The Image.') return render(request, "template/upload.html") class API(APIView): def get(self, request): #API code comes here. The thing is, I can't seem to visualize how to create the API since I am fairly new to it. How can I capture the image name after the form submission and present it in my API view? Can someone explain how it works and what I should do to meet the requirement? Million thanks in advance. -

Django crispy-form changes lay on production server
I cannot seem to understand why crispy-form has changed the layout on my production server vs. the test server. Looking at the html code the only thing I can see is that classes for the form list is changes on the production server. Production Server HTML <div id="div_id_pants" class="control-group"> <label for="id_pants" class="control-label "> Test Server HTML <div id="div_id_pants" class="form-group"> <label for="id_pants" class=""> also noticed that on the test server there is a css file forms.scss.171 that provides the form-group class. Which is not being listed at all on the production site. Any info on where this might be mismatching would be greatly aprieciated. It doesn't look very good atm :( -

How to find whether django hits db [duplicate]

Django ORM unable to retrieve database model instances
I am working on a custom user model that subclasses AbstractBaseUser and a custom model manager that subclasses BaseUserManager.This model, Employee, authenticates by email address - USERNAME_FIELD is set to email. While I can create Employee instances and check my PosgreSQL DB to verify they are being saved, I am unable to retrieve them with the Django ORM and my custom model manager.

Python Django strangely does mapping towards unexpected URL
I tested 1st Django web app project. That app project does mapping towards http://127.0.0.1:8000/api/ when the URL of http://127.0.0.1:8000 comes The test was successful. And then, I tested 2nd Django web app project. That Django app should have performed mapping towards http://127.0.0.1:8000/blog/ when the URL of http://127.0.0.1:8000 occurs.

Django: How to store user specific data like bookmarks, questions
I just learned the basic authentication system in django. I am trying to make a learning website where the user can add courses and ask questions. How do I make the user authentication in a way that each user can have different data on the courses they have added(course completed %, you were views the chapter # etc) and can see all of these in their dashboard. I would also like to have a community for the users to discuss and ask questions. I would be really thankful if someone could explain the courses part to me in a simple way or if there's a link to the topic already on stack overflow or any other website please link it here.

Celery Tasks Won't Purge Properly and Keep Restarting
have a frustrating problem with Celery I was hoping you can help me with. I'm using Redis as my message broker and am using celery in conjunction with Django and celery-beat. I tested a periodic job before that had a mistake in it and could not succesfully run. I terminated celery, typed celery flush, flushed redis and have restarted and million times. No matter what I do, everytime I start celery backup, my old child processes start right where I left them (I think, see console log below). I cannot figure out how to make these things go away! I want every child process that was ever run to DIE! Any suggestions?

Using prefetch_related on specific attributes?
I have the following code: pictures_of_model: Model3D.objects.prefetch_related('Pictures') Pictures is another table in which I store id's for pictures, the pictures themselves in an ImageField and an modelid that is a foreign key. How do I make sure that django prefetches the attribute with the ImageField and not the id of the picture? pictures_of_model: Model3D.objects.prefetch_related('Pictures').picture that can't be correct, right? Picture is my ImageField that holds, well, the picture. I appreciate every answer that helps me learn, thank you! -
