Yii model not bulid relation automatically using gii - php

Question

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.
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;
In model no relation in there :
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(
);
}

This happens sometimes with the gii tool. What you need to do is to comment the relation in the table itself. gii misses the rleationship sometimes but mostly picks it up if available in the comment. So, modify your tables and comment the foreign key as below, it should work.
CREATE TABLE IF NOT EXISTS `location` (
`loc_id` int(11) NOT NULL AUTO_INCREMENT,
`property_id` int(11) NOT NULL COMMENT 'Foreign Key (property_id) references property(property_id )',
`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;
