Newbie trouble with find method and dual many-to-many relati

Hi,

I’m trying to do something which I think is fairly simple, but I’m stuck
on the
syntax. Briefly, I have three classes: users, groups, and
blog_entries.
There’s a M2M relationship between users and groups, and a M2M
relationship
between groups and blog_entries.

I’ve got my classes defined ok, but in my “list” method for the
blog_entries I
only want to list those blog_entries that belong to groups of which the
current
user is a member. Assuming that the current_user is contained in the
@currentUser object, how can I write a graceful find command that will
only
return the records as stated above?

Thanks in advance,

Stan McFarland
