[Unstable] Problem with _validator on serialized models

[Neurergus]

Hi,

In my app, I use the module A1 as the auth system, with a custom driver for Jelly (nothing special). When I log in, the user model is serialized into the session.

One of the fields of the model is a Field_Image type that strictly needs the callback function _upload to return a valid name, or else you end with this:

Database_Exception [ 1241 ]: Operand should contain 1 column(s)
[ UPDATE `users` SET `logo` = ('265432t9h9b8c.jpg', 'image/jpeg', '/tmp/phppiNo2R', 0, 11910) WHERE `users`.`id` = 2814

The problem is that when I try to modify the logo of the object in the session (logged user), the callbacks are never called.

Normally, when _validator is created, you obtain something like this:

object Jelly_Validator
(
    $_validate = array
    (
        [..]

        'rule' = array
        (
            // Lots of rules
        ),

        'callback' = array
        (
            // Lots of callbacks
        )
    )

    [...]
)

But, in that case, the _validator contains:

object Jelly_Validator
(
    'logo' = array
    (
        'name' = 'Balbalba',
        [...]
    )
)

For now, the poorly temp fix I found is to extend the core Model and Meta classes of Jelly, and add this magic method:

public function __wakeup()
{
    $this->_validator = NULL;
}

This way the _validator property is regenerated "every time", and it works.

One curious thing. On my machine it works flawessly without this modifications, but in the two different hosts I tried, I see that bothering error. The difference: my machine has php version 5.3.3 and the other two 5.2.13.

I wish I could say something more useful.

Thanks for this. Looks to be a genuine bug.

Hi,

Upgrading the hosting machine to php 5.3 apparently solved this problem.

Also, my commented "temp fix" is pure shit, read the unpleasant consequences here: http://forum.kohanaframework.org/discussion/6984/solved-session-problem-in-kohana-3.0.8/

I'm a bit confused here. Are you saying that this

public function __wakeup()
{
    $this->_validator = NULL;
}

Doesn't work as a fix? I don't really see why it wouldn't.

It looks like this bug might be related.

[Neurergus]

It fixes this problem, but as you can see in the kohana forums, causes another. But it was a temporary thing anyway.

Yes, probably all this is caused by that php bug.
