Is there a way to access posted data in beforeSave model's callback? (Partially solved)

The fact is, I've been trying to make a password changing form. I've used this approaching so far. I liked it a lot, looks simple, but at the moment I'd like to change password field for the new_password posted in $this->data, at beforeSave it just occurs that posted data is not set.

function beforeSave(){
    if(isset($this->data['Usuario']['password_nueva'])){
        $this->data['password'] = Security::hash($this->data['Usuario']['password_nueva'], null, true);
    }
    return $this->data;
}

Looks like cake uses $this->set() method which unsets all the data not related to the model before calling this callback. Is there a way to keep data posted?

I've noticed that $_Post is available, it's not that pretty, but I'll be开发者_如何学编程 using that...

I though this was a good practice coding that way. Is that true?

I can't check right now, but have a look at $this->params. That's how I get hold of stuff for AJAX (I think).

beforeSave should be able to see $this->data - see http://book.cakephp.org/view/683/beforeSave

I'm not sure why it doesn't work. I've checked my user model code and there are some differences. I've rewritten your code:

function beforeSave(){
    parent::beforeSave();
    if(isset($this->data[$this->name]['password_nueva'])){
        $this->data['password'] = Security::hash($this->data[$this->name]['password_nueva'], null, true);
    }
    return $this->data;
}
