Hello,

I have a simple dataobject like this:

class MyObject extends DataObject {

    static $db = array(
        'Creation' => 'Date'
    );
}

I'd like to have two Model-Admins for the same dataobject.
One should be a normal ModelAdmin alll objects where Creation is in the future.
Another should all objects where Creation is in the past and it should show them as read-only.

I know I can set permission on the MyObject, but that would not solve my problem to be able to have read-only and read-write ModelAdmin.

How is the approach in silverstripe for such cases ?

You need to overwrite ModelAdmin->getEditForm()

class ReadonlyAdmin extends ModelAdmin {
	public static $managed_models = array(
		'MyObject',
	);

	public function getEditForm($id = null, $fields = null) {
		$form = parent::getEditForm($id, $fields);

		// get gridfield
		$gridfield = $form->Fields()
				->dataFieldByName($this->sanitiseClassName($this->modelClass));

		$gridfieldConfig = $gridfield->getConfig();

		// remove delete & edit buttons
		$gridfieldConfig
				->removeComponentsByType('GridFieldDeleteAction')
				->removeComponentsByType('GridFieldEditButton');

		// add a view button
		$gridfieldConfig
				->addComponent(new GridFieldViewButton());

		return $form;
	}
}

However, this is not really secure. You still need to set proper permissions in your DataObject.

I have a question for Delvin.
I also have a simple dataobject:

class Documents extends DataObject {

	private static $db = array(
		'DocType' => 'Text',
		'ApprovalDate' => 'Date',
		'PublicationDate' => 'Date',
		'DocNumber' => 'Text',
		'DocTitle' => 'Text',
		'KeyWords' => 'Text'
	         );

	private static $has_one = array(
		'Member' => 'Member'
	);

Give me please any idea how to customize my ModelAdmin so, that all users could only view all objects, and only owner (user with ID == MemberID) could edit and delete his objects?
As the result I should like to see such picture: [img=" https://yadi.sk/i/o5Nys_szqnPtQ "]
I try to use such code
if (!(Member::currentUserID() ==  $Value_of_MemberID_Field   )) {
    	$gridfieldConfig->removeComponentsByType('GridFieldDeleteAction')
			->removeComponentsByType('GridFieldEditButton');
		// add a view button
		$gridfieldConfig
				->addComponent(new GridFieldViewButton());
} 

How can I get $Value_of_MemberID_Field in the row of GridField?
