In the following page, we briefly introduce some of the changes in this release.
More convenient way to define through AR relation ¶
Active Record though option was introduced in 1.1.7 but syntax wasn't convenient so we decided to make it more definitive. Current syntax is the following:
In the above array('key1'=>'key2'):
key1is a key defined in relation specified in
postsis this case).
key2is a key defined in a model relation points to (
Commentin this case).
through can be used with both HAS_ONE and HAS_MANY relations.
For more details and examples refer to Relational Query with through.
Scope support for Model::relations() ¶
You can now use scopes when defining AR model relations such as
'recentApprovedComments'=>array(self::BELONGS_TO, 'Post', 'post_id', 'scopes' => array('approved', 'recent')),
In case of a single scope you can specify a single scope with a string instead of array.
Ability to join AR models on a specific keys ¶
It is now possible to build AR relations on PK->FK specified instead of relying on the schema defaults so you can specify AR relation like the following declaration for Day model:
'jobs'=>array(self::HAS_MANY, 'Job', array('date' => 'target_date')),
In the case above Day can have multiple Jobs but these aren't related usual way. We've specified relation key in form of array('fk'=>'pk'). That means it will generate SQL like
SELECT * FROM day t JOIN job ON t.date = job.target_date
