Question

I am trying to make a private messaging system, where you send a message to one or more users. Now the messages schema is like

user_id, to_id, msg

How do i make the associations so that i can get the details of the sender and the recipient?

Answer 1

schema:

sender_id
recipient_id

class Message
  belongs_to :sender, :class_name => 'User'
  belongs_to :recipient, :class_name => 'User'
end


class User
  has_many :sent_messages, :class_name => 'Message', :foreign_key => :sender_id
  has_many :income_messages, :class_name => 'Message', :foreign_key => :recipient_id
end
