How to create an object inside the CreateView in Django?

Question

I want to create and save an object in my View using CreateView.

> example in django documentation, uses a form to create new object while I have the fields value (I know the user and the book he selected) and want to create it inside the view, something like this.

from django.views import generic

class BookReserveView(generic.CreateView):
    model = Reservation
    person = current_login_user # the user who logged in
    book = selected_book      # selected book (I have the pk)
    success_url = reverse_lazy('book:reserve_book') # when the object saved go to this url

and this is my Reservation model.

class Reservation(models.Model):

    person = models.ForeignKey(User, on_delete=models.CASCADE)
    book = models.ForeignKey(Copy, on_delete=models.CASCADE)

    date_reserved = models.DateTimeField(auto_now_add=True)

I tried this code and it worked for me. but I like to use generic views (CBV)

from book.models import Copy,Reservation

def BookReserveView(request,pk):
    book = Copy.objects.get(pk=pk)
    reserve_obj = Reservation(book=book, person=request.user)
    reserve_obj.save()
    return HttpResponse(str(reserve_obj))

What error are you getting when you try the CBV you have there? — leelum1, Jun 30 '18 at 13:31
@leelum1 you can't use pk for getting book in the way I use.so it say 'name 'pk' is not defined ' — AmirAsadi, Jun 30 '18 at 22:18

You should use form_valid method inside you CBV look at documentation - https://docs.djangoproject.com/en/2.0/ref/class-based-views/generic-editing/#form_valid, like form.instance.user = self.request.user for giving your values
