François Freitag	a2e97abd81	Fixed #29159 -- Made ModelChoiceIterator reuse QuerySet result cache. When __len__() is called (e.g. when casting to list or tuple), the QuerySet is evaluated and the result cache populated. iterator() shouldn't be called on the QuerySet after that, as it would reset the result cache and trigger a second query.	2018-03-01 14:17:56 -05:00
François Freitag	40f0aa9885	Fixed #29158 -- Fixed len(choices) crash if ModelChoiceField's queryset is a manager. Removing all() in __iter__() prevents a duplicate query when choices are cast to a list and there's a prefetch_related().	2018-03-01 14:12:14 -05:00
