redirect user after update in class based view in django

Question

I'm using Django 1.11.

I'm using Class based view for update profile page, to updated auth user profile info.

myapp/accounts/views.py

class UpdateProfile(UpdateView):
    model = User
    fields = ['first_name', 'last_name']

    template_name = 'accounts/update.html'

    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        self.request = None

    def get_object(self, queryset=None):
        return self.request.user

This works fine for updating profile. But after update, it gives error

No URL to redirect to.  Either provide a url or define a get_absolute_url method on the Model.

I followed some YouTube tutorials here which is using method based view and form.py to generate form, There I can check for request method and call form.save() and then redirect user to profile page (probably index).

1. How can I do I check if data updated and then redirect user to index class in my class?

2. Is this method suitable for editing data using pk?

I also want to generate flash message after updation for which I can use

messages.success(request, "Profile updated")

3. Since class is not have request object, how to use messages in class based view?

Answer 1

You can use the get_success_url method.

def get_success_url(self):
    messages.success(self.request, 'Profile updated')
    return '/' # or whatever url you want to redirect to

The object request is in the self. Note that i don't understand why in your init you're doing self.request = None.
