Thanks pinkp for the reply but i think i have a different problem. when i create a new record in admin i have this tab that allows users to upload files (pdf, jpeg), but it listed all the files that already uploaded. is there any way not show existing files on creating new record? Thanks

Hi UncleCheese,

I have this DataObjects
Nurse :
static $has_many = array(
      'NurseCredentials' => 'NurseCredential'   );
NurseCredentials :
static $has_one = array (
      'Attachment' => 'File',
      'Nurse' => 'Nurse'
   );

in the Nurse admin page i have Credentials tab. When uploading files using Data Object Manager it listed all files that are already uploaded. is there any way not to show existing files on creating new Nurse? Thanks!

the filemanager, by default, displays all the uploaded files, is there a way to hide these files that are not related to the current object that you're working with
