Okay, looks like userDefined isn't implemented yet.
So I tried my luck with beforeValidate() callback, and got it to work
- sort of.
function beforeValidate()
{
$data = $this->data;
if(!empty($this->id))
{
$assetType = ife($this->isFolder($this->id), 0, '> 0');
$result = $this->hasAny(
array(
"{$this->name}.name" =>
$data[$this->name]['name'],
"{$this->name}.{$this->primaryKey}" =>
"!= {$data[$this->name]
[$this->primaryKey]}",
"{$this->name}.parent_id" =>
$data[$this->name]['parent_id'],
"{$this->name}.asset_type_id" =>
$assetType
)
);
}
else
{
$assetType = ife($this->isFolder($this->id), 0, '> 0');
$result = $this->hasAny(
array(
"{$this->name}.name" =>
$data[$this->name]['name'],
"{$this->name}.parent_id" =>
$data[$this->name]['parent_id'],
"{$this->name}.asset_type_id" =>
$assetType
)
);
}
if($result)
{
$this->invalidate('name');
return false;
}
return true;
}
This code prevents Model::save() when appropiate, but I can't get it
to show an error message in the view?
Have tried : <?php e($form->input('name', array('error' =>
'Invalidated')));?>
No luck so far.
Thoughts and comments are very welcome!!
