Model getter/setter not working for me?

[steward]

New to Yii. Unsure why this does not work.

<?php


namespace app\models\video;


use Yii;


/**

 * This is the model class for table "vjobq4".

 *

 * @property integer $id

 * @property integer $vid

...

 * @property string $encoded

 * @property string $meta

 * @property integer $priority

 */

class Job extends \yii\db\ActiveRecord

{

...


    /**

     * @inheritdoc

     */

    public function rules()

    {

        \stewlog::bm('model/video/Job  JOB RULES');

        return [

...		

            [['status', 'data', 'result', 'errors', 'encoded','meta'], 'string'],

        ];

    }


    /**

     * @inheritdoc

     */

    public function attributeLabels()

    {

        \stewlog::bm('model/video/Job  ATTR LABS');


        return [

            'id' => Yii::t('app', 'ID'),

            'vid' => Yii::t('app', 'Vid'),

...

            'meta' => Yii::t('app', 'Meta'),

            'priority' => Yii::t('app', 'Priority'),

        ];

    }


    /**

     * @inheritdoc

     * @return JobQuery the active query used by this AR class.

     */

    public static function find()

    {

        \stewlog::bm('model/video/Job  FIND');

        return new JobQuery(get_called_class());

    }


    public function setMeta($v)

    {

        \stewlog::bm('model/video/Job  SETMETA');


        return json_decode(serialize($v));

    }

    public function getMeta()

    {

        \stewlog::bm('model/video/Job  GETMETA');

        

        return json_encode(unserialize($this->meta));

    }


}

I can verify this model is the one used, but I never see the call to getMeta.

I expected to see the "meta" field unserialized and formatted as JSON. I see the raw mysql data instead, and I get no notice in my log that GETMETA was called ?

What have I overlooked?

Isn’t “meta” a column in the table? Then getMeta() and setMeta() won’t be called when you access “meta”.

If the name of such a property is the same as a class member variable, the latter will take precedence. For example, if the above Foo class has a member variable label, then the assignment $object->label = ‘abc’ will affect the member variable ‘label’; that line would not call the setLabel() setter method.

And, probably what you want to do can be implemented by overriding "afterFind" and "beforeSave".

Thank you very much for pointing that out.

Too many years with other tools, my head was thinking Varien Object. Or some darn thing.

Ok so here is a sample of what worked. This translates dates stored as INT(11) into human readable strings.

    public function init()

    {

        $this->on(self::EVENT_AFTER_FIND, [$this, 'onAfterFind']);

    }

...

    public function onAfterFind($ev)

    {

        $this->tm_encode_start = date('Y-m-d', $this->tm_encode_start);

        $this->tm_encode_end = date('Y-m-d', $this->tm_encode_end);

        $this->tm_upload = date('Y-m-d', $this->tm_upload);

    }

In my terms, getters and setters on the ActiveRecord are for "calculated fields" only. They may not exist in the table.

To mungle actual data we need events. Or, I could invent me own getter, so long as I named it uniquely w.r.t. existing column names.

Experience says that will not cover all the bases. I hope events are at a sufficiently low level so that the bases are buried.

Again thank you. I was head-banging and refused to read that sentence!
