Django FBVs to CBVs - django

Question

I'm refactoring my code and change all FBVs to CBVs. But one of them isn't look pretty well. So I'm asking for right CBVs for my example.
Here my FBVs
#login_required
def profile(request, username):
user_main = get_object_or_404(User, username=username)
user_profile = UserProfile.objects.get_or_create(user=user_main)[0]
form = UserProfileForm({'website': user_profile.website, 'picture': user_profile.picture})
if request.method == 'POST' and request.user == user_main:
form = UserProfileForm(request.POST, request.FILES, instance=user_profile)
if form.is_valid():
form.save(commit=True)
return redirect(profile, username)
else:
print(form.errors)
context_dict = {'user_main': user_main, 'user_profile': user_profile, 'form': form}
return render(request, 'rango/profile.html', context=context_dict)
Here's what I'm got:
#method_decorator(login_required, name='dispatch')
class ProfileView(DetailView, FormMixin):
template_name = 'rango/profile.html'
context_object_name = 'user_main'
form_class = UserProfileForm
def get_object(self, queryset=None):
user_main = get_object_or_404(User, username=self.kwargs['username'])
return user_main
def get_context_data(self, **kwargs):
context = super(ProfileView, self).get_context_data(**kwargs)
context['user_profile'] = self.get_user_profile()
return context
def get_initial(self):
user_profile = self.get_user_profile()
return {'website': user_profile.website, 'picture': user_profile.picture}
def get_form_kwargs(self):
kwargs = super(ProfileView, self).get_form_kwargs()
kwargs['instance'] = self.get_user_profile()
return kwargs
def post(self, request, *args, **kwargs):
self.object = self.get_object()
form = self.get_form()
if form.is_valid and request.user == self.object:
return self.form_valid(form)
else:
return self.form_invalid(form)
def form_valid(self, form):
profile = form.save(commit=True)
return redirect('profile', self.kwargs['username'])
def form_invalid(self, form):
print(form.errors)
return super(ProfileView, self).form_invalid(form)
def get_user_profile(self):
return UserProfile.objects.get_or_create(user=self.object)[0]
I guess my way to solve this task looks horrible. Please show me the right way to make this CBV looks better.
