this tip is emerged from this topic with Mikes great idea to put it in a simple behavior.
So, if you have a defaultScope (e.g. for hiding records with a soft deletion) and you want to disable this default scope in some particular cases (e.g. an admin page where soft deleted records could be undeleted) you may add a behavior like the following:
<?php
class DisableDefaultScopeBehavior extends CActiveRecordBehavior
{
private $_defaultScopeDisabled = false; // Flag - whether defaultScope is disabled or not
public function disableDefaultScope()
{
$this->_defaultScopeDisabled = true;
return $this->Owner;
}
public function getDefaultScopeDisabled() {
return $this->_defaultScopeDisabled;
}
}
?>
inside your model override the defaultScope() function like this:
public function defaultScope()
{
return $this->getDefaultScopeDisabled() ?
array() :
array(
// Your default scope goes here e.g.
// 'condition' => 'deleted=0'
);
}
now you can call your model like this to disable the default scope:
TAKE CARE: I don’t know why, but this editor seems to make the ‘behavior’-part of the classnames lowercase… of course they start with an uppercase ‘B’.
This is realy useful if you call $model->find() method. But did anybody known solution if you need same behavior on related models? Example:
class Category extends CActiveRecord{
...
public function relations(){
return array(
...
'users'=>array(sefl::HAS_MANY, 'User', 'category_id'),
...
);
}
...
}
class User extends CActiveRecord{
...
public function defaultBehavior(){
... some condition ...
}
...
}
// Need get users without default scope of User class
$category->users
Thanks Yoshi, I needed that for the very purpose you mentioned: soft deletes and the possibility to watch the "archive".
I didn’t put it in a behaviour, though, but in the myProjectActiveRecord class which instances all my models and which I also use for the (soft) global beforeDelete(). That’s partly because I’m not too familiar with behaviours and partly because it saves me from adding the behaviour to all my models. It works fine, but I might be doing things “against good practices”.
Anyway, this is how I put it in. Any (mild) critisism is welcome.
abstract class MyProjectActiveRecord extends CActiveRecord
{
/**
* Switch off the default scope
*/
private $_defaultScopeDisabled = false; // Flag - whether defaultScope is disabled or not
public function disableDefaultScope()
{
$this->_defaultScopeDisabled = true;
return $this; // not $this->Owner
}
public function getDefaultScopeDisabled()
{
return $this->_defaultScopeDisabled;
}
etc...
