I solved this problem by using the following function in my model, hope this
can help anybody in the future
function _isUnique($check, $field) {
if(isset($this->data[$this->name]['id']))
{
//make sure that there isn't one on another id that is same as
this field
$results =
$this->find($this->name.'.id<>"'.addslashes($this->data[$this->name]['id']).'"
AND '.$this->name.'.'.$field.'="'.addslashes($value).'"');
} else {
//make sure it doesn't currently exist in the db (we're
creating a new one)
$results =
$this->find($this->name.'.'.$field.'="'.addslashes($check[$field]).'"');
}
if(!empty($results))
{
return false;
} else {
return true;
}
}
