Question

I tried using Kohana/ORM on my localhost xampp and i get the following error

ErrorException [ Notice ]: Array to string conversion
MODPATH\orm\classes\kohana\orm.php [ 980 ]

975             }
976             else
977             {
978                 // List columns and mirror for performance
979                 $this->_table_columns = $this->list_columns();
980                 $this->_table_columns = array_combine($this->_table_columns, $this->_table_columns);
981 
982                 // Load column cache
983                 ORM::$_column_cache[$this->_object_name] = $this->_table_columns;
984             }
985         }

It seems to be a common error appearing in different Frameworks/PHP Applications, but I have not found any clue to fix it.

The Model is just the basic ORM

class Model_Product extends ORM {

}

The Mysql Table (InnoDB – UTF-8) has two fields
id – primary int
name – varchar 50

no voodoo anywhere, help is very appreciated

thanks in advance!

I found a way to resolve this error, just declare the table colums in the model.

protected $_table_columns = array(
    'column' => NULL,
    'names'  => NULL,
    'go'     => NULL,
    'here'   => NULL,
    ......
);

this will ged rid of the problem and increase performance as well.
