New description:
If a project has mulitple apps with templatetags with the same module
name, django will load each of them, but drop all but the last one, and
not inform the user at all, making it quite hard to diagnose.
For example, if you have:
- blog/templatetags/navigation_tags.py
- news/templatetags/navigation_tags.py
- pages/templatetags/navigation_tags.py
then try to use them in a template:
{{{
{% load navigation_tags %}
}}}
then only one of these will be loaded - and there's no report that there
is a problem - but if you attempt to use one of the filters / tags from
one of the libraries that's not the loaded one, it throws a generic
template syntax error saying it's an invalid tag / filter.
== Proposed solution:
Add a new 'check' to the django checks that warns the user if there are
multiple templatetag libraries with the same name.
