Hi,
I’m quite new to Yii. And I’m yet to explore its features & capabilities.
I was developing a small app, and I faced a difficulty with Relation AR.
My scenario:
Two tables - user & friends
CREATE TABLE IF NOT EXISTS `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(20) NOT NULL,
`password` varchar(50) NOT NULL,
`name` varchar(100) NOT NULL,
`email` varchar(100) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;
CREATE TABLE IF NOT EXISTS `friend` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`friend_user_id` int(11) NOT NULL,
`status` varchar(1) NOT NULL,
PRIMARY KEY (`id`),
KEY `user_id` (`user_id`),
KEY `friend_user_id` (`friend_user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;
--
ALTER TABLE `friend`
ADD CONSTRAINT `friend_ibfk_2` FOREIGN KEY (`friend_user_id`) REFERENCES `user` (`id`),
ADD CONSTRAINT `friend_ibfk_1` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`);
Relations I have in my user model
return array(
'friends' => array(self::HAS_MANY, 'Friend', 'friend_user_id'),
'friends1' => array(self::HAS_MANY, 'Friend', 'user_id'),
);
And friend model
return array(
'friendUser' => array(self::BELONGS_TO, 'User', 'friend_user_id'),
'user' => array(self::BELONGS_TO, 'User', 'user_id'),
);
I’m fetching as
$model=User::model()->with(‘friends1’)->findByPk($id);
OK, my intent : I want the friends ‘complete’ info from user table for each friend of the user.
(If user 1 has two friends - 2 & 3, I want complete details of user 2 & 3 when I look for user 1)
How can I achieve that?
With the present relations all I can get the user_id’s of the friends.
Any info regarding this will be very much appreciated.
TIA.
(btw, is it advisable to keep only the login info in user table and keep rest of the profile info in ‘profile’ table?)
