How to get UpdateView to work with generic FormView - django

Question

I have a Formview and an UpdateView which are conflicting with each other. They are supposed to work together but not in this way. Whenever I try to use the UpdateView the values get passed through the FormView for saving which causes it to send back form validation errors
e.g. 'A video with this Title already exists'.
Forms.py:
class BaseVideoUploadForm(forms.ModelForm):
"""
Form for uploading videos using related to:
:model: 'videos.Video'.
"""
title = forms.CharField(
widget=forms.TextInput(
attrs={'placeholder': 'Blackjack shuffle procedures'}))
description = forms.CharField(
widget=forms.Textarea(attrs={'rows': 3}),
help_text='A description of the content in this video.')
category = forms.ModelChoiceField(
queryset=Category.objects.all(),
required=True)
receiver = forms.ModelMultipleChoiceField(
queryset=EmployeeType.objects.all(),
required=True,
widget=forms.CheckboxSelectMultiple,
help_text='Employees in these groups will be able to view the video.')
video_file = forms.FileField()
thumbnail = forms.ImageField(required=False)
class Meta:
model = Video
fields = (
'title',
'description',
'receiver',
'category',
'video_file',
'thumbnail',
)
widgets = {
'date_time': forms.HiddenInput(),
'sender': forms.HiddenInput(),
'unviewed': forms.HiddenInput(),
'viewed': forms.HiddenInput(),
}
def __init__(self, *args, **kwargs):
super(BaseVideoUploadForm, self).__init__(*args, **kwargs)
self.fields['receiver'].label = "Viewers"
self.fields['receiver'].queryset = EmployeeType.objects.all()
self.fields['category'].queryset = Category.objects.all()
class VideoUploadForm(BaseVideoUploadForm):
send_notifications = forms.BooleanField(
required=False,
help_text='Send viewers a notification about the new video.')
class Meta(BaseVideoUploadForm.Meta):
fields = BaseVideoUploadForm.Meta.fields + ('send_notifications', )
FormView:
class VideoUploadView(FormView):
form_class = VideoUploadForm
success_url = '/videos'
template_name = 'videos/video_form.html'
def get(self, request, *args, **kwargs):
form = self.form_class()
return render(request, self.template_name, {'form': form})
def post(self, request, *args, **kwargs):
form = self.form_class(request.POST, request.FILES)
form.instance.sender = self.request.user
if form.is_valid():
form.save()
# doing stuff
form.save()
messages.success(self.request, self.success_message)
if request.is_ajax():
return JsonResponse({'success': True, 'url': reverse('videos-home')})
else:
return redirect(self.success_url)
else:
if request.is_ajax():
return JsonResponse({'success': False, 'error': form.errors})
else:
return render(request, self.template_name, {'form': form})
UpdateView:
class VideoUpdateView(UpdateView):
model = Video
form_class = VideoUploadForm
Urls.py:
urlpatterns = [
path('', views.VideoListView.as_view(), name='videos-home'),
path('upload/', views.VideoUploadView.as_view(), name='videos-upload'),
path('<int:pk>', VideoDetailView.as_view(), name='videos-detail'),
path('<int:pk>/delete/', VideoDeleteView.as_view(), name='videos-delete'),
path('<int:pk>/viewed/', views.mark_as_viewed, name='mark-as-viewed'),
path('<int:pk>/update/', VideoUpdateView.as_view(), name='videos-update'),
path('<int:pk>/notify', VideoNotificationView.as_view(), name='videos-notify'),
]
How do I get the UpdateView to not rely on the FormView? Or to work with the FormView? It seems all the UpdateView is doing is pointing to the FormView.
