DetailView redirect not working in django

Question

I keep getting a reverse error when i try to redirect from a DetailView and CreateView. I keep getting object has no attribute pk. I have equally tried using : args=[str(self.id)]) but i still get the error.

class check (DetailView)
  def get(self, request, *args, **kwargs):
        if...:
             return reverse('no_edit', kwargs={"pk": self.pk})

Answer 1

self is the DetailView object, which indeed has no primary key. If you want to access the object, you normally can use self.object, but since you have overwritten the get method itself, that will not work either.

You can fix it by calling self.get_object() here, like:

from django.shortcuts import redirect

class CheckView(DetailView):

    # …

    def get(self, request, *args, **kwargs):
        self.object = self.get_object()
        if …:
            return redirect('no_edit', pk=self.object.pk)

We can here make use of redirect(..) [Django-doc]. This will construct a HttpResponseRedirect with the result of a reverse call.
