Description
ModelChoiceField
and ModelMultipleChoiceField
cache the output of their queryset
the first time self.choices
is accessed. This is bad for long-running processes, such as mod_python, because the cache gets stale. Plus, it's bad saving all of those choices in memory. The attached unit tests illustrate the problem.
