Modeling messages between users

I want to simulate messages between users, this is what:

  • User received and sent messages and must be found user.received_messages

    anduser.sent_messages

  • The message has a sender and a recipient and must be received message.sender

    and message.receiver

    .

I created a User model as:

script/generate model User name:string

and the message model as:

script/generate model Message content:text sender_id:integer receiver_id:integer

I came up with a Post as below and it works like a wish

class Message < ActiveRecord::Base
    belongs_to :sender, :class_name=>'User', :foreign_key=>'sender_id'
    belongs_to :receiver, :class_name=>'User', :foreign_key=>'receiver_id'
end

but i dont know how to model a user, any advice is appreciated.

As in the Message model:



class User < ActiveRecord::Base
  has_many :sent_messages, :class_name => "Message", :foreign_key => "sender_id"
  has_many :received_messages, :class_name => "Message", :foreign_key => "receiver_id"
end

If you just copied / pasted the code from Milan, then I suspect that the error you are seeing is that there is no half-line before "foreign_key".

The lines should read:



  has_many :sent_messages, :class_name => "Message", :foreign_key => "sender_id"
  has_many :received_messages, :class_name => "Message", :foreign_key => "receiver_id"
