Great!!!

That's exactly that i need!

;-)

thanks so much UncleCheese

Hi Unclecheese, thank you for all your hard work on the DataObjectManager.

I have a need to attach multiple files to Silverstripe pages and keep bouncing my head against the wall trying to get this to work correctly.

I started with the code you posted in this thread on 2 February 2011 at 4:04am, where you listed three files: ResourcePage.php, Resource.php, and ResourceFile.php. Originally, I was getting errors with the $manager-> modifiers until I changed the line $manager = new DataObjectManager(...) to $manager = new FileDataObjectManager(...).

I understand that I need to insert another parameter into the construct after the source class for a "File name on DataObject" but I can't seem to figure out just what to use there. It seems no matter what I try the CMS keeps dying with the error "FileDataObjectManager::__construct():Could not determine file relationship". Using your example code as a start could you shed light on what I need to use there?

Also, utilizing this example will I be able to attach the same multiple files to multiple pages. (ie File1 & File2 attached to both Page1 and Page2)?

Thanks!

Thanks for the fast response!

Sorry for my inexperience in this, but I'm new to Silverstripe and still a little unsure what to use. Following the code from the example, I have three files with the following setup:

File: ResourcePage.php

class ResourcePage extends Page
{
   static $has_many = array (
      'Resources' => 'Resource'
   );

public function getCMSFields()
   {
      $f = parent::getCMSFields();
      $manager = new FileDataObjectManager(
         $this, // Controller
         'Resources', // Source name
         'Resource', // Source class
         '?',   // File name on DataObject
         array(
            'Name' => 'Name',
            'Description' => 'Description',
            'Category' => 'Category',
            'Attachment.Name' => 'Attachment',
         ), // Headings
         'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
         // Filter clause
         // Sort clause
         // Join clause
      );
...

File: Resource.php

class Resource extends DataObject
{
   static $db = array (
      'Name' => 'Text',
      'Description' => 'Text',
      'Category' => "Enum('Industry, Finance, Education')",
   );
   
   static $has_one = array (
      'ResourcePage' => 'ResourcePage'
   );
   
   static $has_many = array (
      'Attachments' => 'ResourceFile'
   );
...

File: ResourceFile.php

class ResourceFile extends File
{   
   static $has_one = array (
      'Resource' => 'Resource'
   );

Which label would I use as the fourth argument?

Thank you UncleCheese! I will give that a whirl!
