I have not looked into $actsAs, will research it as soon as I can.
Basically models have a custom xml component to store highly
customizable data without continuously changing table structure. For
example a model table has only "id", "xml" and "created_at" fields.
AppModel has a DOMDocument property. On model load it would load xml
into dom document. On model save it would save dom document into xml
field. And any customizable data can be accessed via xpath through the
dom document.
class AppModel extends Model {
public $dom;
public function __construct($id = false, $table = null, $ds =
null) {
parent::__construct($id, $table, $ds);
$this->dom = new DOMDocument;
if (isset($this->data[get_class($this)]["xml"])) {
$this->dom->LoadXML($this->data[get_class($this)]["xml"]);
}
}
public function beforeSave() {
if (isset($this->data[get_class($this)]["xml"])) {
$this->data[get_class($this)]["xml"] = $this->dom->SaveXML
();
}
return true;
}
}
If you can offer another way to do it I'd be really interested to
know.
Thanks!

Re: Overloading AppModel constructor
We're in the same boat, I would also like to hear an explanation as to "why" we're not supposed to "do it". But the developer is mostly right, bug tracking is not a support forum, so that's the reason why I went and posted on google groups, hoping may be one of them will actually explain the reason. :-) On Mar 16, 2:21 pm, Alfredo Quiroga-Villamil wrote: > I am not sure if there is an alternative; but to me overlading the > constructor sounds perfectly fine.

Show what you've got and why, and someone will probably point you in
the right direction. probably: do it with a behavior and var $actsAs =
array('Foo'); in your app model.

Quite a big oversight ;)

Re: Overloading AppModel constructor
I am not sure if there is an alternative; but to me overlading the
constructor sounds perfectly fine. I would be interested in hearing
reasons why not to. I did see the comment posted in the bug and I
personally disagree with the comment:
"2) Do not override model constructors."
I would think there is a good reason why not to do that since that was
the response to your issue. It would be interesting to get more
details and not simply say "Don't do it".
I am glad you figured it out.
Regards,
Alfredo

Re: Overloading AppModel constructor
Well, that's exactly what I have. However, how to populate that
property from database automatically during model creation without
overloading __construct() is what the question is.
P.S. I actually figured out that the reason for exceptions was missing
parameters in constructor, so now it works, but still interested to
see if there's an alternative solution.

Re: Overloading AppModel constructor
I haven't tried this; but try it and see what happens.
1- Create app/models/app_model.php
2- In there you can have
class AppModel extends Model {
protected $sYourPropery = 'property';
} // End of AppModel{}
All models that extend AppModel should now have access to
$sYourProperty. In one of your models for example try the following:
public function testing() {
return $this->sYourProperty;
} // End of testing()
and call it from the controller.
Hope that helps.

Alfredo
