Models is an empty Ruby module for housing model classes derived from ActiveRecord::Base. As a shortcut, you may derive from Base which is an alias for ActiveRecord::Base.
module Camping::Models class Post < Base; belongs_to :user end class User < Base; has_many :posts end end
Models are used in your controller classes. However, if your model class name conflicts with a controller class name, you will need to refer to it using the Models module.
module Camping::Controllers class Post < R '/post/(\d+)' def get(post_id) @post = Models::Post.find post_id render :index end end end
A | = | ActiveRecord | ||
Base | = | A::Base |
Base is an alias for ActiveRecord::Base. The big warning I‘m going to
give you about this: *Base overloads table_name_prefix.* This means that if
you have a model class Blog::Models::Post, it‘s table name will be
blog_posts.
ActiveRecord is not loaded if you never reference this class. The minute you use the ActiveRecord or Camping::Models::Base class, then the ActiveRecord library is loaded. |
