#1292 closed defect (fixed)

[patch] Template loader caching can cause circular imports

Description

The template.loader module caches the enabled template loaders in a module global at the time of import. The resulting dynamic imports can lead to problems with circular imports. For example, a circular import will occur if the app_directories template loader is used together with an application that tries to do anything in its __init__.py that triggers another import of template.loader.

The attached patch resolves this problem by caching only on the first call to find_template_source.

I am using Django release 1.5 and I have this error... Why?

I looked in the .py file and the for loop is still global. Honestly this is annoying.
