Question

How can I get the number of affected rows after create, update or delete using ORM for Kohana? I checked the main class but don’t return that value…

If there any possible solution to do this, please let me know. If it is possible not use the Query Builder, i prefer use only the ORM class.

Thank you.

Due to its Cascading Filesystem it’s very easy in Kohana to make some changes in system or module classes.

In your case you need to redefine methods of ORM module main class. Its file is located in /modules/orm/classes/kohana/orm.php.

Create new ORM module main class file in /application/classes/orm.php and redefine create, update and delete methods so these methods to return the number of affected rows.

For example new update method should end with this:

// Update a single record
$update_result = DB::update($this->_table_name)
    ->set($data)
    ->where($this->_primary_key, '=', $id)
    ->execute($this->_db);

if (isset($data[$this->_primary_key]))
{
    // Primary key was changed, reflect it
    $this->_primary_key_value = $data[$this->_primary_key];
}

// Object has been saved
$this->_saved = TRUE;

// All changes have been saved
$this->_changed = array();
$this->_original_values = $this->_object;

return $update_result;
