Display date breakdown in Django

Question

I have a pretty simple question. I want to make some general representations based on the date on the Django site, but I also want to paginate them. According to the documentation, there are page arguments and paginate_by in the object_list view, but this is not in the archive_month view. What is the “right” way to do this?

Answer 1

Date-based generic views are not paginated. It seems you cannot add pagination by wrapping them as well, as they return the result.

Answer 5

Django's generic date-based views do not support pagination. This is open ticket since 2006 . If you want, you can try the code fixes provided to implement this feature. I'm not sure why the patches have not yet been applied to the codebase.
