Import problem in pycharm with django tutorial
Yesterday I started learning django with this tutorial: https://www.youtube.com/watch?v=IMG4r03G6g8 But I am getting an Import Error here: file: django_1/src/dj30/urls.py from django.contrib import admin from django.urls import path from posts.views import post_list_view # ERROR LINE urlpatterns = [ path('admin/', admin.site.urls), path('posts/', post_list_view) ] This is my directory tree: I assume that the Import Error occurs because I am trying to import posts.views.post_list_view from posts/views.py into dj30/urls.py which is in another directory. How does the guy in the tutorial do it? I am positive that I followed the tutorial correctly (I did it twice). Maybe there is a problem with venv because I am using PyCharm (com) and he is not.

Unable to save form using django.views.generic.View

Django modelformset is not validating when trying to update

How to serialize part of a new model based on the user that is logged in (in Django REST framework)
I'm creating a cloud file manager application targeted towards businesses, the project's github is here. I have a Profile model, which is a simple extension of the User model in django.contrib.auth.models by using a OneToOne field as described here. And my use case is that, as a superuser, I should be able to create a profile and assign it to any existing company. But on the other hand, if I'm not a superuser but I am in the "Company Administrator" Group I should only be able to create and edit profiles that belong to my own company. I learned how to used different serializers based on the request in the ViewSet part of the program: class ProfileViewSet(viewsets.ModelViewSet): serializer_class = ProfileSerializer permission_classes = [IsAdminOrCompanyAdmin] def get_queryset(self): u = self.request.user if u.is_superuser: return Profile.objects.all() return Profile.objects.filter(company=u.profile.company) def get_serializer_class(self): if self.request.user.is_staff: return ProfileSerializer return CompanyAdminProfileSerializer But when it comes to the serializer itself, I have no idea how to make it so my company data gets filled in with the company from the request's user: class CompanyAdminProfileSerializer(ProfileSerializer): class Meta: model = Profile fields = ['url', 'user', 'cpf', 'phone_number'] def create(self, validated_data): validated_data['company'] = # ??? # request.user.profile.company would be nice, but I can't … -

Is it possible to user multiple custom user model in django?
I'm trying to make custom user model with AbstarcBaseUer in django 3.1. There are two types of user in my app. Reader, Publisher. Each model should have different fields, so I decided to make two tables for each. First I made Parent class for them, named User which inherit from AbstractBaseUser. class User(AbstarctBaseUser, PermissionMixin): email = models.EmailField(primary_key=True) USERNAME_FIELD = 'email' # and some other fields and setting Second I made Reader and Publisher class which inherit from User class. class Reader(User): # for Reader model Fields class Publisher(User): # for Publisher model Fields Is this structure available in django? And if it is, how do I override UserManger for these?
