If got a table "Article" and a table "Tags". Articles can have multiple tags and tags can hang to multiple articles.
The class BaseArticle looks like this:
abstract class BaseArticle extends Doctrine_Record {
public function setTableDefinition() {
$this->setTableName('article');
$this->hasColumn('article_id', 'integer', 8, array(
'type' => 'integer',
'length' => 8,
'fixed' => false,
'unsigned' => false,
'primary' => true,
'autoincrement' => true,
));
$this->hasColumn('title', 'string', null, array(
'type' => 'string',
'fixed' => false,
'unsigned' => false,
'primary' => false,
'notnull' => false,
'autoincrement' => false,
));
$this->hasColumn('text', 'string', null, array(
'type' => 'string',
'fixed' => false,
'unsigned' => false,
'primary' => false,
'notnull' => false,
'autoincrement' => false,
$this->hasColumn('url', 'string', 255, array(
'type' => 'string',
'length' => 255,
'fixed' => false,
'unsigned' => false,
'primary' => false,
'notnull' => false,
'autoincrement' => false,
));
}
public function setUp() {
parent::setUp();
$this->hasMany('Tag as Tags', array( 'local' => 'article_id',
'foreign'=>'tag_id',
'refClass'=>'Articletag')
);
}
}
The BaseTag-class like this:
abstract class BaseTag extends Doctrine_Record {
public function setTableDefinition() {
$this->setTableName('tag');
$this->hasColumn('tag_id', 'integer', 4, array(
'type' => 'integer',
'length' => 4,
'fixed' => false,
'unsigned' => false,
'primary' => true,
'autoincrement' => true,
));
$this->hasColumn('name', 'string', null, array(
'type' => 'string',
'fixed' => false,
'unsigned' => false,
'primary' => false,
'notnull' => false,
'autoincrement' => false,
));
}
public function setUp() {
parent::setUp();
$this->hasMany('Article as Articles', array( 'local' => 'tag_id',
'foreign'=>'article_id',
'refClass'=>'Articletag')
);
}
}
And the relationship class like this:
abstract class BaseArticletag extends Doctrine_Record
{
public function setTableDefinition()
{
$this->setTableName('articletag');
$this->hasColumn('article_id', 'integer', 8, array(
'type' => 'integer',
'length' => 8,
'fixed' => false,
'unsigned' => false,
'primary' => true,
'autoincrement' => false,
));
$this->hasColumn('tag_id', 'integer', 4, array(
'type' => 'integer',
'length' => 4,
'fixed' => false,
'unsigned' => false,
'primary' => true,
'autoincrement' => false,
));
}
public function setUp()
{
parent::setUp();
}
}
When I try to get a property from the article all goes well by using:
$article = Doctrine_Query::create()->from('Article a')
->where('id = ?' , 1)
->fetchOne();
echo $article->title; //gives me the title
But when I try this:
foreach($article->Tags as $tag) {
echo($tag->name)
}
I get an error:
Unknown record property / related component "Tags" on "Article"
