title: Yii model not bulid relation automatically using gii
body: <p>HI i never faced this type of problem. Please clarify me when i did wrong. I tried to generate 2 model which have relation but it didn't come in models. Here are the Db structure.</p>
  
  <pre><code>CREATE TABLE IF NOT EXISTS `property` (
      `property_id` int(11) NOT NULL AUTO_INCREMENT,
      `ListPrice` int(11) NOT NULL,
      `ListingURL` text NOT NULL,
      `ProviderName` varchar(255) NOT NULL,
      `ProviderURL` text NOT NULL,
      `modificationTimestamp` text NOT NULL,
      PRIMARY KEY (`property_id`)
  ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
  
  CREATE TABLE IF NOT EXISTS `location` (
      `loc_id` int(11) NOT NULL AUTO_INCREMENT,
      `property_id` int(11) NOT NULL,
      `latitude` varchar(255) NOT NULL DEFAULT '0.0000',
      `longitude` varchar(255) NOT NULL DEFAULT '0.0000',
      PRIMARY KEY (`loc_id`),
      KEY `property_id` (`property_id`)
  ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;
  
  --
  -- Constraints for table `location`
  --
  ALTER TABLE `location`
  ADD CONSTRAINT `location_ibfk_1` FOREIGN KEY (`property_id`)
       REFERENCES `property` (`property_id`) ON DELETE CASCADE ON UPDATE CASCADE;
  </code></pre>
  
  <p>In model no relation in there :</p>
  
  <pre><code>public function relations()
  {
      // NOTE: you may need to adjust the relation name and the related
      // class name for the relations automatically generated below.
      return array(
      );
  }
  </code></pre>
