Hi. Currently, I had 2 models linked with HABTM association: Article
and Tag
class Article < ActiveRecord::Base
has_and_belongs_to_many :tags
end
class Tag < ActiveRecord::Base
has_and_belongs_to_many :articles
end
But I believe I need to ad another model called User. Do you know how
processed to get a HABTM association with: Article, Tag and User?
Thx
just an information to be more clear:
I had yet created a table called “articles_tags_users” in the database.

I think you are looking for something like this:

Perhaps by creating a Hub model with three foreign keys, and
using has_many through.

YES! I found the answer:
class Article < ActiveRecord::Base
has_and_belongs_to_many :tags, :join_table => :articles_tags_users
has_and_belongs_to_many :users, :join_table => :articles_tags_users
end
class Tag < ActiveRecord::Base
has_and_belongs_to_many :articles, :join_table => :articles_tags_users
has_and_belongs_to_many :users, :join_table => :articles_tags_users
end
class User < ActiveRecord::Base
has_and_belongs_to_many :articles, :join_table => :articles_tags_users
has_and_belongs_to_many :tags, :join_table => :articles_tags_users
end
have fun!

I think this solution is a little bit so specific and so complexe for my
association need. I hope there is a more simple way include by defaut in
ActiveRecord.

In my context, I prefer using only 3 models with a HABTM association
rather than using 4 models with some has_many through.
Thanks for your ideas.
Some help please!
How do you fill the table with the three foreign keys??
i put
user = User.new
tag = Tag.find(id)
article = Article.find(id)
user.tag << tag
user.article << article
user.save
all this creates 2 tuples on the database articles_tags_users instead of
one
with all the values
