How do I keep reference in Django, when editing existing object?
So I have a field in my model which references another model. Like below. (simplified) class Contents(models.Model): objects = models.Manager() body = models.CharField(max_length=10000, blank=True) image = models.ImageField(null=True, blank=True, upload_to='imgs') created_at = models.DateField(auto_now_add=True) updated_at = models.DateField(auto_now_add=False) class SavedContents(models.Model): objects = models.Manager() ref_content = models.ForeignKey(Contents, on_delete=models.CASCADE, related_name='refcontent', null=True) The problem is, the Foreign Key relationship, where the Saved Contents references Contents, is broken when making changes to an existing Content object. Below is my views.py def update_content(request, content_id): content_to_update = Contents.objects.get(id = content_id) content_form = ContentsForm(request.POST, request.FILES) if request.method == 'POST': if ans_form.is_valid(): instance = content_form.save(commit=False) instance.updated_at = str(today) content_to_update.delete() instance.save() return redirect('/') I know it's quite obvious that the referencing relationship is removed, since the original one is deleted. Is there any way that I can keep the foreign key relationship between that specific Content object and Saved Content object, no matter how many times a user makes changes to the content? Thanks in advance. -

Annotating a Subquery with queryset filtering methods from another model through Many to Many fields
I'm not sure how to make this possible, but I'm hoping to understand the intended method to do the following: I have a simple model: class Author(models.Model): id = models.TextField(primary_key=True, default=uuid4) name = models.TextField() main_titles = models.ManyToManyField( "Book", through="BookMainAuthor", related_name="main_authors", ) objects = AuthorManager.from_queryset(AuthorQuerySet)() class Book(models.Model): id = models.TextField(primary_key=True, default=uuid4) title = models.TextField() genre = models.ForeignKey("Genre", on_delete=models.CASCADE) objects = BookManager.from_queryset(BookQuerySet)() class BookQuerySet(QuerySet): def by_genre_scifi(self) -> QuerySet: return self.filter(**self.LOOKUP_POPULAR_SCIFI) I'd like to add a new QuerySet method for AuthorQuerySet to annotate Author objects using the method from BookQuerySet above. I've tried the following, which is incorrect: class AuthorQuerySet(QuerySet): def annotate_with_total_titles_by_genres(self) -> QuerySet: main_titles_by_genre_sci_fi_query = Book.objects.filter(main_authors__in[OuterRef('pk')]).all() .by_genre_sci_fi() .annotate(cnt=Count('*')) .values('cnt')[:1] return self.annotate(sci_fi_titles_total = Subquery(main_titles_by_genre_sci_fi_query, output_field=IntegerField())) Intended usage: annotated_authors = Author.objects.filter(<some filter>).annotate_with_total_titles_by_genres() The method here is working, and returns a BookQuerySet filtered by the lookup: Book.objects.filter(main_authors__in['some_author_id']).all().by_genre_sci_fi() However when I try to annotate using the above, I get None for every entry. -

Why would someone set primary_key=True on an One to one reationship (OneToOneField)?
I was watching a video on django-orm and the instructor stated that: We should set primary_key=True to prevent a Model from having duplicate rows in a OneToOne relationship (Ex: Prevent a user from having multiple profiles). I know this statement is wrong! AFAIK, an OneToOne field is just a ForeignKey with unique parameter set to True. But I got curious and looked-up the Django documentation, Sure enough they are using primary=True in their example. class Place(models.Model): name = models.CharField(max_length=50) address = models.CharField(max_length=80) class Restaurant(models.Model): place = models.OneToOneField( Place, on_delete=models.CASCADE, primary_key=True, ) So, why would someone set primary_key=True on an OneToOne relation? My guess is that it's just reasonable to have that field as a primary key and there is no technical background behind it. -

I have a problem with authenticate() method. It always returns None. I checked all my arguments and they are not empty. In models i have USERNAME_FIELD = 'username', in settings i have AUTH_USER_MODEL = 'account.User'. I really cant understand why it's not working. Help please models.py class User(AbstractBaseUser): id = models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='id') email = models.EmailField() username = models.CharField(max_length=25, unique=True) is_active = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) education = models.CharField(max_length=100, blank=True) date_of_birth = models.DateField(blank=True, null=True) name = models.CharField(max_length=25, blank=True) last_name = models.CharField(max_length=25, blank=True) objects = UserManager() USERNAME_FIELD = 'username' views.py class UserLoginView(ObtainAuthToken): serializer_class = UserLoginSerializer serializers.py class UserLoginSerializer(serializers.Serializer): username = serializers.CharField(required=True) password = serializers.CharField(required=True) def validate_username(self, username): if not User.objects.filter(username=username).exists(): raise serializers.ValidationError('User wasn\'t found') print(User.objects.get(username=username).password) return username def validate(self, data): # authentications request = self.context.get('request') username = data.get('username') # test_name password = data.get('password') # newpassword11 if username and password: user = authenticate(username=username, password=password, request=request) print(user) if not user: raise serializers.ValidationError('Invalid password') else: raise serializers.ValidationError('You have to type you\'re mail and password') data['user'] = user return data
