The idea is to allow links on month/day views to never be 404s by never providing a date that'll be invalid for the given view. This is a bit complicated since it handles different intervals of time, hence the coupling to generic_view. However in essence the logic comes down to: * If allow_empty and allow_future are both true, this is easy: just return the naive result (just the next/previous day/week/month, regardless of object existence.) * If allow_empty is true, allow_future is false, and the naive result isn't in the future, then return it; otherwise return None. * If allow_empty is false and allow_future is true, return the next date *that contains a valid object*, even if it's in the future. If there are no next objects, return None. * If allow_empty is false and allow_future is false, return the next date that contains a valid object. If that date is in the future, or if there are no next objects, return None. z_get_current_%sz _get_next_%sr& rE Nrp r| ro r r )r_ r� ra �getattrrG rH r� rn rh r r� rc r� Zorder_by� IndexErrorr rl � localtimer" )Z generic_viewr" r r r] r� r` Z get_currentZget_next�start�end�resultr� r} r� r� r r r r � sB r c C s t jrt�� S tj�� S dS )z1Return the current date in the current time zone.N)r rl r Z localdaterG r" r� r r r r r� s r� )r� r� r� r� r� )/rG Z django.confr Zdjango.core.exceptionsr Z django.dbr Z django.httpr Z django.utilsr Zdjango.utils.functionalr Zdjango.utils.translationr r Zdjango.views.generic.baser Zdjango.views.generic.detailr r Zdjango.views.generic.listr r r r6 r? rL r\ rt r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r r� r r r r �<module> sD 25/@CW.$4), � Z
