Many-to-many associations: Simple

Many-to-many associations: Simple: Ruby on Rails 5 Essential Training
Many-to-many associations: Simple: Ruby on Rails 5 Essential Training

Learn to work with many-to-many associations in Rails. Many to many associations are used when an object has other objects which belong to it, but not to it exclusively. Because of this, these associations need to use a join table to keep track of which objects have relationships to other objects. In Rails we define both sides using “has_and_belongs_to_many”. In a simple many-to-many association, the join table does not include an “id” as a primary key and there is no model corresponding to the database join table.
