django createview how to get the object that is cr

问题:

i've two concatenated form. Basically user fills in the first form and then is redirected to the second one which adds value to the data of the first form. E.G. I've a form Movie (first form) and then i'm redirected to the form (actor) which add the actor to the movie.

in my case the Movie = Chiamata and Actor = Offerta (i keep the italians name for what i need :D)

fine.

those are my urls in the urls.py

url(r'^chiamata/$', ChiamataCreate.as_view(),name='chiamata_create'),
url(r'^chimamata/(?P<pk>\d+)/offerta$', OffertaCreate.as_view(), name='offerta_create'),

i've this create view

class ChiamataCreate(CreateView):
    template_name = 'chiamata_form.html'
    form_class = ChiamataForm
    success_url=reverse_lazy('offerta_create',args=(??,))

now the problem is how i can get the PK of the object created by the chiamataForm. I need that to add it to the the url of offerta_create.

回答1:

maybe you could use get_success_url() method (see reference)

In this case, it'd be something like:

def get_success_url(self):
    return reverse('offerta_create',args=(self.object.id,))

Please see the accepted answer on Why doesn't self.object in a CreateView have an id after saving to the database? - once I removed the "id" fields from my models, and let Django default to its own id AutoField on each model as recommended in that answer, self.object.id worked fine in my CreateView.
