hee guys..
I have a problem with HABTM...
I have articles en users... wich are connected to rights... beceause
users can have more then 1 right and rights can have more than one
user... and the same by articles of course
I have 3 models:
the user: has_and_belongs_to_many :rights
the article: has_and_belongs_to_many :rights
and rights: has_and_belongs_to_many :users
has_and_belongs_to_many :articles
and 2 join tables.
I have a user_id and I want to list all the articles which he has access
to:
@user = User.find_by_id(2)
@right = @user.rights
@article_list= @right.articles
but this doesn''t work... Does anyone now how to get multiple articles
from one user ?

Re: multiple HABTM ..
Hello, You are actually getting a array of rights from this: @right = @user.rights So not a right per se. You should call @right.articles on a Right object... Julien.
