function get_form_kwargs() not being called

[Simon A]

I'm trying to pass a parameter from a redirect to the CreateView and to the form.

I have no problem retrieving the value from the redirect to the CreateView.

But my issue is when trying get the value to the form. I'm overriding get_form_kwargs function of my CreateView but when I try to do operations from that function, I'm not able to get any result. I tried to do a print but the print won't display anything.

class NoteCreate(LoginRequiredMixin, CreateView):
    login_url = 'login'
    model = Note
    form_class = NoteForm
    success_url = reverse_lazy('note:list')

    def get_form_kwargs(self):
        kwargs = super(NoteCreate, self).get_form_kwargs()
        kwargs.update({'file_id' : self.kwargs['file_id']})
        print("im alivveeeeeeeEeeeeeeeeeeeee!")
        return kwargs

the print statement doesn't seem to be working. It does not show anything in the console.

I'm able to render the form with no errors in the console.

I identified that a more efficient way of doing this would be to call the get initial method but for some reason it doesn't seem to trigger the function that I'm trying to overriede.

class NoteCreate(CreateView):

    login_url = 'login'

    model = Note

    form_class = NoteForm

    success_url = reverse_lazy('file_status:list')

    def get_initial(self):

        print(self.kwargs['file_id'])

        print('in get initial')

        initial = super(NoteCreate, self).get_initial()

        initial['file'] = 2

        return initial

Please help me understand. this is really getting frustrating:(

For this one, the text in get initial does not get printed.

What works though is when I don't use Class based view. But I still would like to make it work using class based views since my other views are class based.

Fascinating.  It looks normal, though login_url is not a member of CreateView.

Do you perhaps have another class defined with the same name?

Especially since you do have other class-based views, you must know what you’re doing.

I double checked, this view is unique.

here's the whole process by the way.

from a detail page, there is a link that redirects to a create note page. also, the id of the parent object.

<a href="{% url 'file_status:note_create_param' object.pk  %}" class="badge badge-secondary">Create note</a>

then on my url.py, I have two paths pointing to the same view class. one has no parameter, the other has a parameter which I will be using.

path('note_create/', views.NoteCreate.as_view(), name='note_create'),
path('note_create_param/<int:file_id>/', views.NoteCreate.as_view(), name='note_create_param'), # this is what I'm using

here's my view

class NoteCreate(CreateView):
    login_url = 'login'
    model = Note
    form_class = NoteForm
    success_url = reverse_lazy('file_status:list')

    def get_initial(self):

        print('at get intitial method')
        return None

maybe I'll start another crud cookie cutter project to see if the get initial method will work on that.

Just to add, I used a django-crud cookie cutter to generate codes for CRUD

Oh shoot, I think I know now why this isn't working for me. 

It is because I'm using vanilla for my views. I'll continue to test.

And it really is that. I had to follow the steps required by vanilla migration procedure to make it work like I want it to.
