join tables

there 2 types of bring together table - has_and_belongs_to_many & has_many :through

they same thing (create many-to-many relationship), means can phone call @model.objects through join model

from reading information, looks this:

#app/models/user.rb class user < activerecord::base has_many :applications has_many :companies, through: :applications end #app/models/application.rb class application < activerecord::base #fields - id | user_id | company_id | etc | etc | created_at | updated_at belongs_to :company belongs_to :user end #app/models/company.rb class company < activerecord::base has_many :applications has_many :users, through: :applications end
