Just Checked In:
AssetManager: Allows management of files directly to a page. No need to go through a dataobject. Usage:
$field->addFieldsToTab("Root.Content.Files", new AssetManager($this,"Files","MyFileClass"));
Where "Files" is the name of the file relation, and MyFileClass is the subclass of File that has a $has_one relationship with your page. If you want to use the File class directly, it would require modifying the File class to have that has_one relation, which requires a decorator. Still possible, though. If you choose to do if that way, the third argument defaults to "File" so all you need is:
Because we can now manage files directly, it is now possible to use the AssetManager in the AssetAdmin interface. By default, this is turned on in the latest version of DataObjectManager in dataobject_manager/_config.php. Just set true/false with:
Not much to speak of here, but over time I'm going to be making updates to some of the weaker points of the Silverstripe core stylesheet. These updates will come in through dataobjectmanager_override.css. By default these overrides are turned off, but can be enabled in the config file.
For relation DataObjectManagers, you can now set the permissions required to alter the checked state of each item. Usage:
By default, there are no permission restrictions on altering relations.
Other Stuff Mentioned Before But Still Cool
SWFUploadField: Now has speed calculation and countdown timer for uploads once five seconds have elapsed.
FileDataObjectManager: Now disables imports for file types that are not allowed.
DataObjectManager: Now has a "deselect all" option for HasOne/HasMany managers. This is especially useful for the HasOne manager, since it allows you to set a null value by clearing the radio buttons.
