Description
django.utils.functionals.LazyObject does not proxy the __contains__ and __len__ data methods. This means that the following use cases for lazy objects that return lists, sets or dicts are not possible:
key in lazy_object len(lazy_object)
Fixing this is trivial as has been shown by the current proxying implementation of __getitem__, __setitem__ and __delitem__. Regression test and patch is available on Github at https://github.com/nickbruun/django.
