Ruby Question
Get a model reference from ActiveRecord_Associations_CollectionProxy object
I have two Active Record Models
class User < ActiveRecord::Base
has_many :posts
end
class Post < ActiveRecordd:Base
end
I would like to get the reference of the class Post from the activerecord association.
user.posts.get_object_class
Currently when I do
user.posts.class.to_s
# Post::ActiveRecord_Associations_CollectionProxy
Is there a way I can get Post without having to "split" the string on "::" and then constantize it ?
Answer
Use model or klass attribute - it will return the constant you are looking for:
user.posts.model
#=> Post
user.posts.klass
#=> Post
See apidocs for more details.
