How to apply a decorator to all views (of a module) in django

In your urls

url(r'someregexp/$', mydecorator(view.myview.dude), 'name_of_view'),

When using class-based views you can create a base class/mixin for all these views which implements the desired functionality (also using decorators) and then have all the views inherit from this base view.

from django.views.generic import TemplateView

class BaseView(TemplateView):

    def get(self, request, *args, **kwargs):
        # do some checking here
        if not request.user.is_authenticated():
            # do something if anonymous user
        return super(BaseView, self).get(request, *args, **kwargs)


class MyView(BaseView):
    pass
