RoR: belongs_to_many relationship in Rails?

I have a Model of Key Termsthat can belong to many Articles (1 Term can be used in many articles)? so a user can add key terms used and their explanations to articles for which they are used in? what would be the best way to establish this relationship?

Thank You

You'll want to use a many-to-many relationship so you'll need to use has_and_belongs_to_many (see here). And you'll need to create an interim table for key_term_id and article_id columns named key_terms_articles to maintain the connection.

I think what you want is what's referred to as a HABTM (has and belongs to many) relationship. There's a lot of stuff out there on the topic, and it can be a bit confusing at first to grasp. Try searching for "activerecord HABTM" or "Activerecord polymorph" and that should get you started.
