Django-CMS warning on django-mptt

Question

I have a Django-CMS 2.4.1 project that always gives me the warning:

DeprecationWarning: Implicit manager CMSPlugin.tree will be removed in django-mptt 0.6.  Explicitly define a TreeManager() on your model to remove this warning.

This only occurs in production - not in dev.

I tried:

./manage.py cms fix-mptt

which gives me the output (after the same warning as above):

fixing mptt page tree
fixing mptt plugin tree
all done

But... this does not solve the problem, e.g. if I repeat the command it does the same thing again, with the same warning.

The warning doesn't seem to be doing any harm yet, but I imagine it will with the next version of django-mptt. Can anyone give me any advice?

thanks

Answer 1

You can safely ignore that warning in any case.

It's just telling you that django CMS's use of Django MPTT is relying on something that will be removed in a future version.

Answer 2

Harmless but utterly annoying, make the b*tch shut up:

CMSPlugin.tree = CMSPlugin.objects

in any module of early execution (models.py for example).
