Django class based views. Use same custom class for different url

I would like to know if it would be possible to create only a custom class for my views in django that could be valid for different urls.

For example:

#urls.py 
url(r'^$', CustomClass.as_view(), name='index'),
url(r'^other_url/(?P<example>[-\w]+)$', CustomClass.as_view(), name='other')

#views.py
CustomClass(View):
    # for / url
    def first_method(self, request):
        pass
    # for other_url/
    def second_method(self, request, example):
        pass

I have readed the documentation about class based views, but in the example only talks about a single url... https://docs.djangoproject.com/en/1.9/topics/class-based-views/intro/

So, I suppose I have to create a class for each url. But it would be possible use the same class with different methods for different url?

You don't need to create different classes for different urls. Although it is pretty redundant to have the same class in different urls, you could do:

url(r'^$', CustomClass.as_view(), name='index'),
url(r'^other_url/(?P<example>[-\w]+)$', CustomClass.as_view(), name='other')

exactly what you're doing. There are some cases where you have a generic class you want to use (either generic from the generics module/package, or generic in the OOP sense). Say, an example:

url(r'^$', CustomBaseClass.as_view(), name='index'),
url(r'^other_url/(?P<example>[-\w]+)$', CustomChildClass.as_view(), name='other')

Or even the same class with only different configuration (regarding generic classes (descending from View): accepted named parameters depend on how are they defined in your class):

url(r'^$', AGenericClass.as_view(my_model=AModel), name='index'),
url(r'^other_url/(?P<example>[-\w]+)$', AGenericClass.as_view(my_model=Other), name='other')

Summary You have no restriction at all when using generic views, or passing any kind of callable at all, when using url.
