Django: 'current_tags' is not a valid tag library

python django portability

I have a small Django project I received from a friend. The code works perfectly on his system. However, on my system I get the following error message when running the server:

TemplateSyntaxError at /

'current_tags' is not a valid tag library: Template library current_tags not found, tried django.templatetags.current_tags

The problem is with a line in an html file:

{% load current_tags %}

This exact same code works on his system with no errors. What could that be?

I would suggest the following:

  1. (Most likely) You haven't installed one of the dependencies of your tag library. Check the imports inside the current_tags.py module.

  2. Make sure the application that includes the tag library is registered in settings.py under INSTALLED_APPS.

  3. Make sure that you can successfully import the tag library.

    python manage.py shell
>>> from app.templatetags import current_tags

    This boils down what the following link recommends, which is that the error itself tends to mislead you about where it's looking for a template from. It silently ignores errors on import, which means current_tags.py itself might have a syntax error or another reason why it raises ImportError.

If everything else fails, check this link: http://www.b-list.org/weblog/2007/dec/04/magic-tags/
