Incompatibility between django-audit-log and django-modeltranslation

I found a solution to this problem. This original problem description is kept here, allowing others with the same issue to find the description and the solution.

This is a small Django project that utilises both django-audit-log and django-modeltranslation. It contains the Django app app with the model MyModel. Also included is a simple test for the model.

The project is set up with a SQLite database running in memory.

When running the tests via ./manage.py test, the following unexpected exception is raised:

TypeError: 'text_es' is an invalid keyword argument for this function

The complete output is here:

$ ./manage.py test
Creating test database for alias 'default'...

If the audit log for the model is disabled (e.g. by removing or commenting out this line), tests pass as expected.

Similarly, if translation of the model is disabled (e.g. by removing or commenting out this line), tests also pass as expected.

But when both features are enabled, the above problem occurs.

This issue has been reported for django-audit-log and django-modeltranslation.

The Solution

After a while, and after going through the sources of both packages (yay, open source!) it suddenly struck me what the problem was and how to solve it: You simply need to register the auto generated audit log models for translation as well as the regular models, as seen in this branch comparison.
