这是我ClientSetupView的pod_funnel.py观点：

form_class = ClientSetupForm
template_name = 'pod_funnel/forms.html'
# In the get we manage the request to get the form and prefill it if necessary
def get(self, request, *args, **kwargs):
# We need to check first if the current user has a client and podcast setup,
# if so, prepopulate. Otherwise get empty form.
initial_values = {}
user = request.user
if Client.objects.filter(user=user).exists():
client = CLient.objects.filter(user=user).first()
initial_values['first_name'] = client.first_name
initial_values['last_name'] = client.last_name
podcast = Podcast.objects.filter(client=client).first()
request.session['client_id'] = client.id
if podcast:
initial_values['podcast_name'] = podcast.name
# lets store podcast_id in session so we can retrieve it directly in post
request.session['podcast_id'] = podcast.id
form = self.form_class(initial=initial_values)
return render(request, self.template_name, {'form': form})
# In the the post we manage updates to the data
def post(self, request, *args, **kwargs):
form = self.form_class(request.POST)
if form.is_valid():
# lets get the data
first_name = form.cleaned_data.get('first_name')
last_name = form.cleaned_data.get('last_name')
podcast_name = form.cleaned_data.get('podcast_name')
# First we see if we have a client_id in session, if so we retrieve and update
# otherwise we create a new one.
client_id = request.session.get('client_id', None)
if client_id is not None:
request.session.delete('client_id')
client = Client.objects.get(id=client_id)
else:
client = Client()
client.first_name = first_name
client.last_name = last_name
client.company_name = podcast_name
client.save()
# Now we update or create the associated podcast.
podcast_id = request.session.get('podcast_id', None)
if podcast_id is not None:
request.session.delete('podcast_id')
podcast = Podcast.objects.get(id=podcast_id)
else:
podcast = Podcast()
podcast.client = client
podcast.name = podcast_name
podcast.save()
success, message_list = update_or_create_preset_for_podcast(podcast)
# in any case we can continue with additional podcast setup, but we need
# to attempt to create the preset one more time at some point before the
# user can create the first productions.
return HttpResponseRedirect(reverse('podfunnel:podcastsetup'))
return render(request, self.template_name, {'form': form})
在您的发布方法中提供：
user = request.user
if client_id is not None:
request.session.delete('client_id')
client = Client.objects.get(id=client_id)
else:
client = Client.objects.create(user=user) # your user must not be empty
