belongs-to

Having a large model stack and using doll caching techniques extensively, one ends up with lots of parent models been "touched" after a model update. While testing, this seems to be a time waster unless you try to test that feature specifically.

Let's say I have the following model: class Movie extends Eloquent { public function director() { return $this->belongsTo('Director'); } } Now I'd like fetch movies using a where condition that's based on a column from the directors table.

How to build relationship where I'll be able to get user for both sender and recipient, like @message.sender.name and @message.recipient.name I tried to do it by this way: class Message < ActiveRecord::Base belongs_to :sender, :class_name => 'User', :foreign_key => 'sender' belongs_to :recipient, :class_name => 'User', :foreign_key => 'recipient' end class User < ActiveRecord::Base has_many :recivied_messages, :class_name => 'Message', :foreign_key => 'recipient' has_many :send_messages,
