How do I pass arguments to django forms?
I want to filter form fields querysets based on the user selected. Therefore, I want to pass user as argument to the form in order to filter fields querysets in the form's __init__ method. When I pass any arguments to the form I get the following error. class UserDetailView(LoginRequiredMixin, FormMixin, DetailView): model = TbUser form_class = TbPeopleEntranceRightForm def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) form = TbPeopleEntranceRightForm(user=self.object) context['form'] = form return context __init__() got an unexpected keyword argument 'user' how do I pass the argument correctly, and how I get it in the __init__ form method? -

I wanna paginate in class view, but an error happened "Cannot filter a query once a slice has been taken."
I wanna implement pagination in ListView in Django. I can rewrite the view in function view, but I wanna know how to do pagination in class view for practice. What I wanna do here is to get data filtered by logged in user and display them with pagination by 20(doesn't matter the number). For example, if Alex is currently logging in, I wanna display Alex's data from the database paginated by 20. But, when I wrote the code below, I got an error "Cannot filter a query once a slice has been taken." So, now on the HTML file, there are all users' data like Alex's data, Bob's data, Lisa's data, and all other users' data. I tried to put paginate_by = 20 under the get_context_data function, but doesn't work. I even think I may not use paginate_by with get_context_data. class FoodList(LoginRequiredMixin, ListView): model = Food template_name = 'base/all_foods.html' context_object_name = 'foods' ordering = ['-created'] paginate_by = 20 def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['color'] = 'red' context['foods'] = context['foods'].filter(user=self.request.user) Let me know if I need to put more info. Any advice is helpful and thank you for your help in advance!! -

Failing to render object data from Django API to Vuejs frontend
I've worked with Django 3.x for almost two years now and have just started using Vue js for about a week using the documentation to try and learn the intended way. So far my api access points work as intended whenever I DON'T use the Vue frontend to create objects. So, down to the code. I've tried to send the report via a prop from the Home.vue to the Detail.vue but for some reason it doesn't seem to load more than the noc_ticket.

Use output of multiple views in one view with single url
So i am fairly new to Django and here is what i want: Say i have Three Views, View 1, 2 and 3. Each one with their own Template, Http response ,context and everything. Now i know how to Use 3 separate URLs for each view but what i would like to do is Just have one url for say View 3 and Outputs of View 2 and 3 are merged or concatenated whatever you wanna say in the view 3 itself. I am doing this because i have a lot of context and doing one view and single template results in a large code. At the moment i am using Class Views but i am open to you use function views. I want to know if there is a way i can Get Output/Results of View 1 and 2 in View 3 combined. Note: If someone is familiar with React and the components thats kind of what i am trying to do. Like making two components separately and then have a container component to call them. P.S. i am not using react i just thought this will explain what i am trying to do. -

Django: How can I create a model from a POST request?
To put it on context, I would like to let users create models using a form in the templates. That way the can create multiple different models if necessary. Example: Let's say, as an user I want to create a form that takes the name and phone number of a person. Then I'd like to create another form that takes a name, a time and a phone number. What would be the best approach to doing this task? -
Update data in postgres using def update - Django
I have a method to create a new item in my database that works fine. But when creating the similar method to update, it is creating a new item instead of updating the existing one, and if I force the id to pass in "data", it complains that this id already exists... My CODE: class EventsAttachmentsViewSet( mixins.ListModelMixin, mixins.CreateModelMixin, mixins.UpdateModelMixin, mixins.DestroyModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet ): permission_classes = [permissions.AllowAny] queryset = EventAttachment.objects.all() serializer_class = EventAttachmentSerializer def create(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) data = serializer.validated_data self.perform_create(serializer) headers = self.get_success_headers(serializer.data) return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers) def update(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) data = serializer.validated_data self.perform_update(serializer) headers = self.get_success_headers(serializer.data) return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers) -
Django Auth Group refuses to change in UpdateViews
I'm having a problem to update the User Group field after the User creation. The focus here is do this kind of thing outside the Admin page, in common UpdateView that will have limited access for certain groups. What bugged me is that the Group selection and saving of the EditForm and EditView is identical to the CreationForm/CreationView, and those work flawlessly. It just refuses to change, it doesn't throw any error, just like there were no relations between this tables (auth_group and users_customuser_groups) at all. views.py class UserEdit(LoginRequiredMixin, UpdateView): form_class = EditUserForm template_name = 'registration/edit_profile.html' success_url = reverse_lazy('dashboard') def get_object(self): return self.request.user def post(self, request, *args, **kwargs): form = EditUserForm(request.POST) if form.is_valid(): user = form.save(commit=False) user.save() group = Group.objects.get(name=form.cleaned_data['group']) group.user_set.add(user) group.save() form.save() return redirect('dashboard') models.py from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, Group from django.db import models from django.utils import timezone from django.utils.translation import gettext_lazy as _ from .managers import CustomUserManager from institutes.models import Institute class CustomUser(AbstractBaseUser, PermissionsMixin): email = models.EmailField(_('email address'), unique=True) name = models.CharField(max_length=255) is_staff = models.BooleanField(default=False) is_active = models.BooleanField(default=True) date_joined = models.DateTimeField(default=timezone.now) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] objects = CustomUserManager() group = models.ForeignKey(Group, on_delete=models.CASCADE, default=1) institute = models.ForeignKey(Institute, verbose_name='institute', on_delete=models.CASCADE) def __str__(self): return str(self.name) forms.py class EditUserForm(UserChangeForm): … -
