Filtering a model in a CreateView with get_queryset

Question

I\'m trying to filter a model with get_queryset() and it seems to work in the view but not in the template.

My view :

class FolderCreate(CreateView):

The issue here is that get_queryset is not used in a CreateView, as it's meant for filtering the models returned for display in a list or detail view. You want something completely different: you want to filter the choices available in a form field.

To do that you will need to create a custom ModelForm that accepts a user kwarg and filters the queryset accordingly:

class FolderForm(forms.ModelForm):
    class Meta:
       model = Folder
       fields = ['name', 'parent']

    def __init__(self, *args, **kwargs):
       user = kwargs.pop('user')
       super(FolderForm, self).__init__(*args, **kwargs)
       self.fields['parent'].queryset = Folder.objects.filter(user=user)

and then change your view to use that form and pass in the user parameter:

class FolderCreate(CreateView):
    template_name = 'Form/folder_create.html'
    form_class = FolderForm

    def get_form_kwargs(self):
        kwargs = super(FolderCreate, self).get_form_kwargs()
        kwargs['user'] = self.request.user
        return kwargs
