New ActiveModel class base that allows you to define n different ActiveRecord models to search from:

class User < ActiveRecord::Base
  attributte_accessor :name, :email, :login
end

class Organization < ActiveRecord::Base
  attributte_accessor :name, :email, :description
end

class YourNewClass < ActiveModelUnion::Base
  union_model :user, :organization

  union_attribute :name, :email, :login
end

YourNewClass.where(email: 'me@gmail.com' ).all

Relation model that allows us to chain operations as union on to each one of the union models. Right now we have:

• where
• limit
• order
• joins
• count
• to_sql
• all
• paginate

We can aditionally make some of the operations just in one of the union models by using the _in methods:

YourNewClass.where_in(:user, email: 'me@gmail.com' ).all

right now we have:

• where_in
• joins_in
