Django and DRF Why isn't my password hashing
I am using DRF and I have these pieces of code as models, register view and serializer But anytime I signup a user the password does not hashed and I can't see to figure out why. models.py class UserManager(BaseUserManager): def create_user(self, email, password=None): if not email: raise ValueError("Users must have an email") email = self.normalize_email(email).lower() user = self.model(email=email) user.set_password(password) user.save() return user def create_superuser(self, email, password, **extra_fields): if not password: raise ValueError("Password is required") user = self.create_user(email, password) user.is_superuser = True user.is_staff = True user.save() return user class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(max_length=255, unique=True) first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) role = models.CharField(max_length=255) department = models.CharField(max_length=255) is_active = models.BooleanField(default=True) is_verified = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) objects = UserManager() USERNAME_FIELD = "email" REQUIRED_FIELDS = ["first_name", "last_name", "role", "department"] def __str__(self): return self.email serializers.py class RegisterSerializer(serializers.ModelSerializer): email = serializers.CharField(max_length=255) password = serializers.CharField(min_length=8, write_only=True) first_name = serializers.CharField(max_length=255) last_name = serializers.CharField(max_length=255) role = serializers.CharField(max_length=255) department = serializers.CharField(max_length=255) class Meta: model = User fields = ["email", "password", "first_name", "last_name", "role", "department"] def create(self, validated_data): return User.objects.create(**validated_data) def validate_email(self, value): if User.objects.filter(email=value).exists(): raise serializers.ValidationError("This email already exists!") return value views.py class RegisterView(APIView): serializer_class = RegisterSerializer def post(self, request, *args): serializer … -
How to display the progress of a function in an html page Django?
I'm learning Django, tell me if it's possible to implement my idea. In the file views.py I have a script def index(request): .... for i in range(100000): print(i) return render(request, 'main/index.html', {'title': 'Website main page', 'tasks': ...}) How can I display these prints in the index.html page? If I insert the variable i into render, then the page is in the process of waiting and, as a result, shows only the last value in the iteration. I understand why this is happening. But how can I then display online in the process - what happens in the terminal, all the values in the enumeration? It seems to me that javascirpt is needed for this - I think or is it possible to display this in a simpler way? -

Different user types with Django default auth
For my Django project, I have 3 different user types. I use boolean flags to know what kind of user is the actual one and have 3 models with one to one relation to the user model and the extra fields for each one: class Usuario(AbstractUser): es_centro = models.BooleanField(default=False) es_tutor = models.BooleanField(default=False) es_proveedor = models.BooleanField(default=False) class Centro(models.Model): usuario = models.OneToOneField(Usuario, on_delete=models.CASCADE, primary_key=True) provincia = models.CharField(max_length=20) localidad = models.CharField(max_length=50) codigo = models.PositiveIntegerField(null=True, blank=True) cursos = models.ManyToManyField(Curso) class Tutor(models.Model): usuario = models.OneToOneField(Usuario, on_delete=models.CASCADE, primary_key=True) dni = ESIdentityCardNumberField() centro = models.ForeignKey(Centro, on_delete=models.CASCADE) class Proveedor(models.Model): usuario = models.OneToOneField(Usuario, on_delete=models.CASCADE, primary_key=True) nif = ESIdentityCardNumberField() now, i want to use the default auth urls to manager the users. I have something like this: urlpatterns = [ path('admin/', admin.site.urls), path('', views.index, name='index'), path('centros/', include('django.contrib.auth.urls')), path('centros/registro', views.centrosregistro, name='centrosregistro'), path('tutores/', include('django.contrib.auth.urls')), #path('tutores/registro', views.tutoresregistro, name='tutoresregistro'), path('proveedores/', include('django.contrib.auth.urls')), #path('proveedores/registro', views.proveedoresregistro, name='proveedoresregistro'), ] each user type have a path where auth.urls are included. These urls look for templates in a default folder called 'registration', where there has to be a login.html, logout.html, ...

Pagination doesn`t work with extra context in Django ListView

How to write dynamic Django URL's to capture data and pass to a view for processing
So I am writing a simple website with Django, with some basic CRUD features. The website has 7 main models in total.

what is the type of django default authorisation?
I have created a django application and I'm using the default Django authorisation. I have 'django.contrib.auth' and 'django.contrib.contenttypes' in my installed apps. I have made some endpoints that display a json if you have already loged in. It works very good in the browser, it askes user and pass and shows the data. However when I want to get the data for example with Postman I dont know which kind of auth I should choose. with basic auth I give user name and password but the message is not authorized user. can someone please help me with what type of auth I should get the data from django? -

How do I exclude 'self' instance from a ManyToMany field which references the 'self' model?
I have a 'Pizza' model that can inherit 'Toppings' from another instance of 'Pizza'. When I go to update the Pizza, to add new toppings, I need to prevent the user from selecting the 'self' instance of Pizza in the parent list. For Example: I create Margarita pizza with cheese and tomato toppings. I then create another Pizza (Pepperoni) and inherit all toppings form the Margarita. I need to stop Pepperoni from appearing in the 'parents' list to stop a circular reference. models.py class Topping(models.Model): name = models.CharField(max_length=100) class Pizza(models.Model): name = models.CharField(max_length=100) parents = models.ManyToManyField("self", symmetrical=False) toppings = models.ManyToManyField(Topping) forms.py class PizzaForm(ModelForm): toppings = forms.ModelMultipleChoiceField( queryset=Topping.objects.all(), widget=forms.CheckboxSelectMultiple, required=False ) parents = forms.ModelMultipleChoiceField( queryset=Pizza.objects.all(), widget=forms.CheckboxSelectMultiple, required=False ) class Meta: model = Pizza fields = '__all__' views.py class PizzaUpdateView(UpdateView): model = Pizza form_class = PizzaForm I suspect I need to amend the parent queryset in PizzaForm to exclude a PK, but I'm unsure of how to hand this through to the form from my view. -

How to get a QuerySet with values of a specific field in Django while maintaining the order?
class Book(models.Model): name = models.CharField(max_length=10) Book.objects.bulk_create([ Book(name='A'), Book(name='B'), Book(name='C'), ]) book_names = ['C', 'D', 'A', 'B'] some_func(book_names) # >>> [Book(name='C'), None, Book(name='A'), Book(name='B')] When I have a list of values of a specific field of a model object, is there a way to implement a function that returns the model object in the same order in the list and returns None when the value does not exist? I want to implement it using only Django ORM query without using for loop. preserved = Case(*[When(name=name, then=pos) for pos, name in enumerate(book_names)]) Book.objects.filter(name__in=book_names).order_by(preserved) # >>> [Book(name='C'), Book(name='A'), Book(name='B')] In this way, I can get list of objects in the same order, but I don't know how to get None when the value doesn't exist. -
