Django FormWizard and Permissions

Question

I was wondering if there is a way to use permission decorators for Django's FormWizard. I know there is a way to do it via the urlconf, but I would like to avoid this and have my permissions all set up via the views.

I tried to override MyFormWizard.as_view() and add the decorators there, but then realised that as_view() is a @classonlymethod.

I don't have a lot of experience with Class Based Views and was wondering if there is an easy way to add the permission decorator on one of the FormWizard's methods? Any clues?

You don't have to decorate the view in the url conf. You can do so in your views.py,

protected_wizard_view = login_required(MyWizardView.as_view())

and then import protected_wizard_view in your urls.py.

(r'^wizard/', protected_wizard_view),

Another other option is to decorate the dispatch method, as described in the docs.

class MyWizardView(WizardView):

    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super(MyWizardView, self).dispatch(*args, **kwargs)
