python - No URL to redirect to. Either provide a url or define a get_absolute_url method on the Model -

i using createview build form. createview called detailview. once form submitted, want validated, submitted data returned initial detailview.

the detailview calls createview fine. form works expected until submitted. then, error: no url redirect to. either provide url or define get_absolute_url method on model.

i tried using this solution, kicks out same error. tried passing data , redirecting through url calls createview. still same error.

can please tell me how redirect createview original detailview (and passing validated data?

the best way add method get_success_url on create view , use redirect detail view. in create view have object after saved, so

class lawyerreviewcreate(createview): def get_success_url(self): return reverse('lawyer_detail', kwargs={'lawyer_slug': self.object.lawyer_slug})

this automatically send user detail view if form valid.

also, make sure kwargs using correct key, appear using review_slug in cases , lawyer_slug in other cases
