When i try to create an inline field in admin.py for a manytomanyfield i
always get the following error:
<class 'politlog.app.models.Class'> has no ForeignKey to <class
'politlog.otherapp.models.OtherClass'>

It seems like django doesnt support inlines for ManyToManyFields whereas
the documentation says otherwise:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#working-with-many-
to-many-intermediary-models

I've described my problem also here:

Comment:

The documentation you reference refers to many-to-many models that use an
intermediate table, not to m2m relations in general.

New description:

When you try to create an inline field in admin.py for a manytomanyfield
you always get the following error:
<class 'MyClass'> has no ForeignKey to <class 'OtherClass'>

It would be nice to be able to use inlines for many to many relations.

Comment:

I'm not aware of any plans to add this feature. I've modified this ticket
to reflect the feature request.

You may get your wish through a back channel. The changes required by
#10109 will probably make this feature possible with no extra effort, as
that ticket will require introducing a dummy model representation of m2m
fields, and this dummy model may be compatible use in inlines. I plan to
commit a fix for #10109 in the near future as a precursor to multiple-
database and non-SQL backend support. I'll try to keep this ticket in mind
before I commit.
