Doctrine Framework in Yii Framework

Hi Guys,

I hope you can help me.

I'm new to the Yii Framework but I already finish a little project and Yii is great!

But now I have to develop a bigger project with DB and I want to use the Doctrine Framework for all DB operations.

Now is the question, how can I use it??

I extract the lib into "protected/vendors/Doctrine/"

and I create the following controller:




class wtzController extends CController


	protected $DB;


	public function  __construct($id)


		$this->DB = new Doctrine_Query();





which I use for controllers.

But I get the exception:

include(Doctrine_Query.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory

I hope somebody can help me!

Best regards


Where is Doctrine_Query.php located?



/protected/vendors/Doctrine/doctrine.php -> Main file with autoload function

/protected/vendors/Doctrine/Doctrine/query.php -> Doctrine_Query class

/protected/vendors/Doctrine/Doctrine/Many files and folders

Because the class file does not have the same name as the class name, Yii is unable to load it automatically. You will need to install a separate autoload function (maybe it is provided by Doctrine already?)

You may also explicitly include the needed files.


I'm having the same problem. Doctrine also has it's own autoload function in Doctrine.php and is also called autoload(). I tried renaming this function to doctrine_autoload() and ran the following code.

require_once ('protected/vendors/Doctrine/lib/Doctrine.php');

// register the autoloader



Doctrine::loadModels('classes'); // This call will not require the found. php files

When it comes to the Doctrine_Manager statement, Yii is still trying to use the YiiBase autoload() function to load the Doctrine_Manager class and it errors out.

How do I install the doctrine_autoload() function to be called only if it's tryiing to load a Doctrine class? Should I edit YiiBase.php autoload() function? Is that the correct way to do it?

Thanks for your help in advance.

This code works for me:

require_once(dirname(__FILE__) . '/framework/vendors/doctrine/Doctrine.php');

spl_autoload_register(array('Doctrine', 'autoload'));

$manager = Doctrine_Manager::getInstance();

I got it working finally. The problem is that the YiiBase::autoload function is the first in the autoload stack and it errors out in that function before it goes to the Doctrine autoload function. If the YiiBase::autoload function returned a false if it didn't find the file, the stack would progress to the next autoload function. This has been done in the Doctrine autoload function. so I essentially put the Doctrine Autoload function first in the stack and readded the YiiBase::autoload second. Now it works.

Note: Do NOT rename the autoload function in doctrine since it is called explicitly in some places in Doctrine.

Here's the hack I used.

require_once ('protected/vendors/Doctrine/lib/Doctrine.php');

// register the autoloader






Doctrine::loadModels('protected/models'); // This call will not require the found. php files

Hope that helps. I however would like to know if this is the right way to do it?

Any comments guys?

Thanks in advance,

Yes, calling Doctrine's autoload is the right way to go.

Maybe you can post your findings as a [url=/doc/cookbook]cookbook page[/ur]?
