Overview of Active Record Associations
Active Record Associations allow you to define relationships between models in Ruby on Rails.
Associations make it easier to work with related data and provide a more intuitive way of interacting with your database.
Types of Associations
Ruby on Rails supports several types of associations, including:
- One-to-One
- One-to-Many
- Many-to-Many
Each type of association has its own use cases and is used to model different types of relationships between models.
Creating Associations
To create an association, you need to define it in your model using the appropriate association method.
class User < ApplicationRecord
has_one :profile
has_many :orders
end
