I am trying to create a product form by 'Create View' as a class-based view, but it tells there is an issue in the terminal as the following snippet.

models.py

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

class Products(models.Model):
    
    def __str__(self):
        return self.product_name
    user_name=models.ForeignKey(User, on_delete=models.CASCADE, default=1) 
    product_name=models.CharField(max_length=200)
    product_descript=models.CharField(max_length=200)
    product_price=models.IntegerField()
    product_image=models.CharField(max_length=500, default='#')

    def get_absolute_url(self):
        return reverse('food:detail', kwargs={'pk':self.pk})

url.py

from django.urls import path
from . import views

urlpatterns=[ 
          path('addj',views.CreateProduct.as_view(),name='add_product'),
          ]

views.py

from django.views.generic.edit import CreateView
from .models import Products

 class CreateProduct(CreateView):
   model= Products
   fields=['product_name','product_descript','product_price','product_image']
   template_name='food/product-form.html'
   def form_valid(self,form):
       format.instance.user_name=self.request.user
       return super().form_valid(form)

product-form.html

<form method="POST" >
  {% csrf_token %} 
{{form}}
 <button type="submit">
</form>

Can someone help me with this regard?

Thanks

Error is from views.py so you have to ways to solve error

1. You have wrong import of CreateView. correct is from django.views.generic import CreateView.

2. You can split form and view as given below. preferred way is 2nd method.

Code for forms.py

#forms.py

from django import forms
from .models import Products

class CreateProductForm(forms.ModelForm):
    class Meta:
        model = Products
        fields=['product_name','product_descript','product_price','product_image']

Code for views.py

# views.py
from django.views import generic
from django.urls import reverse_lazy
from .forms import CreateProductForm

class CreateProduct(generic.CreateView):
    form_class = CreateProductForm
    template_name='food/product-form.html'
    success_url = reverse_lazy('home')
