Models.py file contain Shop, Product, User model which is stored in sqlite default database

class Product(models.Model):
    shop = models.ForeignKey(Shop, on_delete=models.CASCADE)
    name = models.CharField(max_length=128)
    category = models.CharField(max_length=32)
    lot = models.DecimalField(max_digits=16, decimal_places=0)
    specs = models.CharField(max_length=5120)
    price = models.FloatField(max_length=16)
    product_logo = models.FileField(default='')


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

    def __str__(self):
        return self.name

Forms.py this is form field which is used to create form for the model

class ProductForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = ['name', 'category', 'lot', 'specs', 'price', 'product_logo']

Views.py here is the code for the AddProduct which is i thing contain error but i am not able to find what.

    login_url = '/login_user'
    redirect_field_name = 'redirect_to'
    model = Product
    fields = ['name', 'category', 'lot', 'specs', 'price', 'product_logo']

    def form_valid(self, form):
        object_product = form.save(commit=False)
        object_product.shop = self.request.shop
        object_product.save()
        return super(AddProduct, self).form_valid(form)

using kwargs we can get vaule of the primary key and we can use that value to get the object Shop

urls.py

 url(r'^(?P<pk>[0-9]+)/add_product/$', views.AddProduct.as_view(), name='add_product'),

views.py

pk = self.kwargs['pk']
object.shop = get_object_or_404(Shop, pk=pk)

and by doing this we can able to store the value to the database.

by the way thanks for helping @malberts
