On a related note, some lookups depend on the INSTALLED_APPS settings and others depend on the list of applications registered in the AppCache. The latter may be a superset of the former. We should give some thought to this problem before committing to a given discovery behavior. Eventually, Django should probably raise an error when the AppCache loads a model from an application than isn't in INSTALLED_APPS. But there may be uses cases for this eg. dynamically generated models.

We could change it to a list, however, that will introduce inconsistencies with other settings where the default value is a tuple and can't be changed without introducing backwards incompatibilities. > > 1. be more explicit in the documentation > > Yes! -- Aymeric. -- You received this message because you are subscribed to the Google Groups "Django developers" group.
