CakePHP and Containable

Let me start out by saying I've tried to read the CakePHP book as much as I can for this particular topic, and for whatever reason, I just cannot figure this out.

I have a few models:

Person

• each person can have many jobs
• each job has 开发者_JS百科one branch and each branch belongsTo one city.

At first I was relying on recursive, but its not customizable enough (obviously) do get the data that I want.

I either get WAY too much data in my output array, or hardly any at all.. I just can't figure this containable out, and if I could see an example of what I'm trying to do it would be great...

Thanks

since you've read the Cookbook up and down I won't go through all the basic details with you and just try to explain how to use the containable.

You can use the containable with the find-functions from your models. Either from your controller or directly from your model.
Most of the time I use the controller so I will give you an example how you would do it from there. I also try to use your specific example, so you have something to work with.

/app/controllers/people_controller.php

function index() {
    //I like to write a separate array for fields and contain
    $fields = array(
        'name',
        'birthday',
        'gender'
    );

    /* It's important to know, that the fields will not get included into the
     * contain-array unless it's an associated model! */
    $contain = array(
        'Job' => array(
            //within another array you define the next level of contain
            'Branch' => array(
                //you get the deal...
                'City'
            ),
            //if you only need specific fields you can define this here like this:
            'fields' => array('title', 'date', 'salary'),
            //or order them directly!
            'order' => 'Job.salary DESC'
        )
    );

    //we now to our find-fall with our 2 arrays for the fields and the contain
    //every option (like fields or order) can be used in the containable
    $people = $this->Person->find('all', array('contain' => $contain, 'fields' => $fields));
}

I hope this helped you in understanding containable a little more.
