Проблемы пользователей Django Modelform

У меня есть модель формы для списка товаров, и я пытаюсь заставить форму заполнить идентификатор пользователя от пользователя, который отправляет форму. В настоящее время форма успешно отправляется, но она всегда использует идентификатор первого пользователя в базе данных для каждого элемента.

models.py

class Item(models.Model):
id = models.UUIDField( primary_key=True, default=uuid.uuid4, editable=False )
creator = models.ForeignKey( get_user_model(), on_delete=models.CASCADE, default=2)
item_name = models.CharField(max_length=40)
price = models.DecimalField(max_digits = 6, decimal_places=2)
description = models.CharField(max_length= 500)
main_image = models.ImageField(upload_to=path_and_rename , max_length=255, null=True, blank=True)
image_2 = models.ImageField(upload_to='items/', blank=True)
image_3= models.ImageField(upload_to='items/', blank=True)
image_4= models.ImageField(upload_to='items/', blank=True)
image_5= models.ImageField(upload_to='items/', blank=True)
quantity = models.IntegerField(default=1, validators=[ MaxValueValidator(100),MinValueValidator(1)])
created_on = models.DateTimeField(auto_now_add=True)
updated_on = models.DateTimeField(auto_now=True)

def __str__(self):
    return self.item_name

def get_absolute_url(self):
    return reverse("item_detail_view", args=[str(self.id)])

forms.py

from django.forms import ModelForm, forms
from .models import Item

class List_Item_Form(ModelForm):
forms.ModelChoiceField(queryset=Item.objects.filter(user=user))
   
    class Meta:
        model = Item
        
        def __init__(self, *args, **kwargs):
            user = kwargs.pop("user", None)
            super().__init__(*args, **kwargs)

views.py

class AddListing( generic.CreateView):
    template_name = 'store/add_listing.html'
    fields = ('item_name','price','description','main_image','quantity')
    model = Item
    def form_valid(self, form):
        self.object = form.save(commit=False)
        self.object.user = self.request.user
        self.object.save()
        return super().form_valid(form)

Это можно сделать и с помощью представления, основанного на function, потому что там нам легче получить current пользователя.

Попробуйте это:

models.py

from django.db import models
from django.contrib.auth.models import User


class Item(models.Model):
    creator = models.ForeignKey(User, on_delete=models.CASCADE)
    item_name = models.CharField(max_length=40)
    price = models.DecimalField(max_digits=6, decimal_places=2)
    description = models.CharField(max_length=500)
    main_image = models.ImageField(
        upload_to=path_and_rename, max_length=255, null=True, blank=True)
    image_2 = models.ImageField(upload_to='items/', blank=True)
    image_3 = models.ImageField(upload_to='items/', blank=True)
    image_4 = models.ImageField(upload_to='items/', blank=True)
    image_5 = models.ImageField(upload_to='items/', blank=True)
    quantity = models.PositiveIntegerField(default=1)
    created_on = models.DateTimeField(auto_now_add=True)
    updated_on = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.item_name

admin.py

from django.contrib import admin
from home.models import Item
@admin.register(Item)
class ItemRegister(admin.ModelAdmin):
    lis_display = ['id', 'creator', 'item_name', 'price', 'description']

from . import views
urlpatterns = [
    path('', views.list, name='home'),
    path('success/', views.success, name='success')

                  'description', 'quantity']

def list(request):
    if request.method == 'POST':
        form = ListItemForm(request.POST)
        if form.is_valid():
            itemName = form.cleaned_data['item_name']
            price = form.cleaned_data['price']
            desc = form.cleaned_data['description']
            quan = form.cleaned_data['quantity']
            main_img = form.cleaned_data['main_image']
            current_user = request.user
            model_instance = Item(creator=current_user, item_name=itemName, price=price,
                                  description=desc, quantity=quan, main_image=main_img)
            model_instance.save()
            return HttpResponseRedirect('/success/')
    else:
        form = ListItemForm()
    return render(request, 'store/add_listing.html', {'form': form})


def success(request):
    return render(request, 'store/success.html')
