Django CBV DetailView - accessing the object to assign to a context variable?

I want to assign a specific field of an object to another context variable. With function based views, this is simply a matter of declaring the key:value pairs:

context = {
  'title': my_object.nick_name
}

Now in my template, I can use the variable {{ title }} and it'll display the object's field nick_name.

How would I achieve the same thing with Class Based Views?

For example, I have this simple DetailView:

class MyObjDetail(DetailView):
  model = MyObject

  def get_context_data(self, **kwargs):
    context = super(MyObjectDetail, self).get_context_data(**kwargs)
    context['title'] = ????? <--- right here
    context['cancel'] = reverse_lazy('my_objs:my_objs_list')
    return context

I want to assign the variable {{ title }} to be the nick_name field of the object being displayed with this class based view. How would I do that?

In the DetailView, you'll be able to access the object with self.object. Therefore you should do:

context['title'] = self.object.nick_name

However, you might find it easier to simply access the nickname via the object in the template:

{{ object.nickname }}
