Ruby on Rails Mongoid Classic Associations
30% OFF - 9th Anniversary discount on Entity Framework Extensions until December 15 with code: ZZZANNIVERSARY9
Example
Mongoid allows the classic ActiveRecord associations:
- One-to-one:
has_one/belongs_to - One-to-many:
has_many/belongs_to - Many-to-many:
has_and_belongs_to_many
To add an association (lets say the User has_many posts), you can add this to your User model file:
has_many :posts
and this to your Post model file:
belongs_to :user
This will add a user_id field in your Post model, add a user method to your Post class, and add a posts method to your User class.
