Binding One-To-One foreign key associations is done with Doctrine_Record::ownsOne() and Doctrine_Record::hasOne() methods.
|
|
In the following example user owns one email and has one address. So the relationship between user and email is one-to-one composite.
|
|
The relationship between user and address is one-to-one aggregate.
|
|
|
|
|
|
|
|
The Email component here is mapped to User component's column email_id hence their relation is called LOCALKEY relation.
|
|
On the other hand the Address component is mapped to User by it's user_id column hence the relation between User and Address is called
|
|
FOREIGNKEY relation.
|
|
|
|
<code type="php">
|
|
class User extends Doctrine_Record {
|
|
public function setUp() {
|
|
$this->hasOne('Address','Address.user_id');
|
|
$this->ownsOne('Email','User.email_id');
|
|
$this->ownsMany('Phonenumber','Phonenumber.user_id');
|
|
}
|
|
public function setTableDefition() {
|
|
$this->hasColumn('name','string',50);
|
|
$this->hasColumn('loginname','string',20);
|
|
$this->hasColumn('password','string',16);
|
|
|
|
// foreign key column for email ID
|
|
$this->hasColumn('email_id','integer');
|
|
}
|
|
}
|

public function setTableDefinition() {
