One class-based view object for multiple urls depending on parameters

Question

I have multiple urls whose mission is almost identical (generate a list page with the corresponding context). So my urlpatterns is something like:

url('^by-country/(?<arg1>\w+)', MyO.as_view(), name='by-country'),
url('^by-period/(?<arg1>\w+)', MyO.as_view(), name='by-period'),
url('^by-age/(?<arg1>\w+)', MyO.as_view(), name='by-age')

Is there a way to pass the by-blabla string in a one class based view without making it as a second regex named argument in my urlpatterns?

Since I use a View derived class (i.e. MyO), I cannot pass anything to it except already-declared attributes (e.g template_name). So, is there any clean way to do it?

All url patterns accept a third positional argument, which is a dict of extra parameters to pass to the view that are not derived from the regex itself. So:

url('^by-country/(?<arg1>\w+)', MyO.as_view(), {'category': 'by-country'}, name='by-country'),

Are the extra arguments passed to the dispatch method of a class based view?

Thanks Daniel!, but where do I extract the category parameter? In my get method?

Thanks, it can be obtained from kwargs!
