Rails - Mar 2008 - comment.user associations with acts_as_commentable

I''m using acts_as_commentable and running in to a problem when trying
to
access objects associated with the comment.user.

For example: My app has groups, and a group belongs to a user. If I
write group.user.comments, I''ll see a hash for every comment that the
group.user has made. However, if I try comment.user.groups, ActiveRecord
tells me that the ''groups'' method doesn''t exist for
user. The ''groups''
method does exist when I write user.groups, however. So I''m betting
this
has something to do with the polymorphic associations in
acts_as_commentable; but at the moment I don''t understand how to make
comments.user.groups work the way I want it to. Does anyone know what
I''m missing?

I finally fixed this by creating my own commentable associations. I 
don''t know why   I had to do so - maybe it''s something to do
with how
plugins inherit from activerecord - but my comment.user.groups 
associations are now working just fine.

Hi Paul

It''s been ages since I fixed this and I''m not even using
polymorphic
comments anymore. However, I believe the problem was fixed by simply 
creating my own polymorphic comments and dropping the plugin altogether. 
This is pretty easy to do. Just run the migration, create the comment 
model, set up the associations between the user and the comment, and 
that''s it. The plugin (something to do with it being loaded as a plugin
and a separate module, presumably) seemed to break the associations that 
belonged to the user.

Hope that helps
