Thanks also for your help. I tryed some hours to get all this working
but also without success.
Fortunately, i found a link to a nice validate function: (http://
bin.cakephp.org/view/653776884 -> Thanks a lot to the author!!!)
This code works for my with add and edit.
I simply included a 'notEmpty' rule and it was done. :)
So here is my source:
[code]
var $validate = array(
'location_id' => array(
/* In the parameters, after 'description', there can be added
more fields to validate */
'rule' => array('noDuplicates',
array('description', 'location_id')),
'message' => 'this combination of Location and Description
is already in use'
),
'description' => array(
'rule' => 'notEmpty',
'message' => '"Description" cannot be left blank'
)
);
/* Checks to see if there is already a duplicate of the specific
combination of fields */
function noDuplicates($value, $params)
{
/* if editing an existing record then don't count this record in
the check for duplicates */
if (!empty($this->id))
$conditions[] = array($this->primaryKey . ' <>' => $this-
>id);
/* Add a condition for each field we want to check against */
foreach ($params as $field)
{
/* check if value is empty. if it is then check for a NULL
value against this field */
if($this->data[$this->name][$field])
$fieldVal = $this->data[$this->name][$field];
else
$fieldVal = null;
$conditions[] = array($field => $fieldVal);
}
$existingFieldsCount = $this->find( 'count', array('conditions'
=> $conditions, 'recursive' => -1) );
return $existingFieldsCount < 1;
}
[\code]
The function can by included in the current model or in the app_model.
