    GridField Error in Security/Members SS 3.0.2 Link to this post

    Hey guys,

    First time posting, but I'll try to be as clear as possible.

    I've added some new fields to the "Members" section of my install, and come across a problem when trying to view/edit the members in the CMS through the GridField.

    [User Error] Uncaught LogicException: GridField doesn't have a modelClassName, so it doesn't know the columns of this grid.

    I've seen this error posted in the forums, but for different reasons, so I'm not sure if they apply to this.

    The code I'm using:

    class UserDecorator extends DataExtension {
       // Add extra database fields
       public static $db = array(
          'Username' => 'Varchar(255)',
          'UserLocation' => 'Text',
          'UserDOB' => 'Date',
          'UserHardwareCase' => 'Varchar(255)',
          'UserHardwareRAM' => 'Varchar(255)',
          'UserHardwareCPU' => 'Varchar(255)',
          'UserHardwareGFX' => 'Varchar(255)',
          'UserHardwareStorage' => 'Varchar(255)',
          'UserHardwareMonitor' => 'Varchar(255)',
          'UserHardwareMotherboard' => 'Varchar(255)',
          'UserHardwareKeyboard' => 'Varchar(255)',
          'UserHardwareMouse' => 'Varchar(255)',
          'UserHardwareMousepad' => 'Varchar(255)'
       public static $has_one = array(
          'UserAvatar' => 'Image'

    Any insight would be greatly appreciated. Thanks.
