ExtendsError at /admin/ Cannot extend templates recursively when using non-recursive template loaders

[m-vdb]

I get this error when I want to extend my admin/base.html template. It works properly when dbtemplates.loader.Loader is not in the TEMPLATES settings, but when it is (even if I try to load a template that is not from the database), I get this error:

I am not familiar with template loaders but I can help if needed. I think the issue comes from these lines. And to enable this parameter the get_contents() method on the loader needs to be implemented (as per this).

LMK if I can help more.

Oh I see that it is tackled in #87. How can I help?

Is this problem still applicable?
