How to get keword argument from url in django class based views?

Question

Is there any way to get keyword argument declared in url.py inside class based views methods?

For example: I want to override get_initial(self) to set one of the values to value from url. Do I really need to override __init__ to do that?

Answer 1

You can do it like this:

arg_value = self.kwargs.get(ARGUMENT_NAME, None)

Which is how it is done in the SingleObjectMixin, which provides the get_object functionality used in DetailView.
