Howdy all,

Quick question about adding form actions to Model Admin. I am using a decorator to add new form actions to object that is managed by a model admin subclass. I can add a new form action (i.e., next to save, delete) with the updateCMSActions hook, and can use the same call to sneak in the required javascript, however there does not appear to be a way to add a new method to the model admin (or, more specifically, the appropriate ModelAdmin_RecordController wrapper).

My code so far:

class MyCustomDecorator extends DataObjectDecorator {

	public function updateCMSActions(FieldSet &$fields) {
		Requirements::javascript('my_new_module/javascript/FormActions.js');
		if($this->owner->canEdit(Member::currentUser())){
			$fields->push(new FormAction('doSomeAction', 'My New Form Action'));
		}
	}

}

// javascript
// (replicated behavour from ModelAdmin.js)
(function($) {
$(document).ready(function() {
	/**
	 * Decommission button 
	 */
	$('#right #form_actions_right input[name=action_doSomeAction]').livequery('click', function(){
		var form = $('#right form');
		var formAction = form.attr('action') + '?' + $(this).fieldSerialize();
		
		// Post the data to save
		$.post(formAction, form.formToArray(), function(result){
			$('#right #ModelAdminPanel').html(result);
			
			statusMessage(ss.i18n._t('ModelAdmin.SAVED'));

			Behaviour.apply(); // refreshes ComplexTableField
			if(window.onresize) window.onresize();
		}, 'html');

		return false;
	});
})})(jQuery);

All groovy so far. The button appears within the ModelAdmin and clicking it will send a request to the following url:

http://mycoolsite/admin/mymanagedobject/theobject/1/EditForm?action_doSomeAction=SomeAction

But this returns a 500 error:

[User Error] Uncaught Exception: Object->__call(): the method 'dosomeaction' does not exist on 'Form'

This was not entirely unexpected, since I couldn't see any way to add the appropriate method to the record controller. Ideally, method 'doSomeAction' would live in the decorator, or the record controller would check for the method within the object (and, and applied decorators).

Without this capability, it would seem that the updateCMSActions method breaks modeladmin.

Any ideas?

Hi Hamish-

I know this is an old post I'm responding to... wondering if you've had any luck in adding actions to Model Admin? I'm in the same position with a project.

Thanks for your time!

Hi Hamish

I would very much like to know too if you made this work?

heres a solution if somebody still needs it.. know its an old post

just extend ModelAdmin_RecordController with your own RecordController class and overwrite the static $record_controller_class with your class like:

public static $record_controller_class = "XYZ_RecordController";

please ignore if obsolete...

I found a solution for this topic, I know it's been a while, but I'd like to compare if anyone else has a solution to determine the best and most understandable way to accomplish adding actions to model admin.

Task, add Process action, when pressed it simply checks the Processed field
In DataObject:
function getCMSActions()
{
$actions = parent::getCMSActions();
$actions->push(new FormAction('doProcess','Process') );
return $actions;
}
function doProcess()
{
/* more complicated tasks can be performed here */
$this->Processed = 1;
return $this->write();
}

In ModelAdmin.js
/**
* RHS panel Process button
*/
$('#right input[name=action_doProcess]').live('click', function(){
var form = $('#right form');
var formAction = form.attr('action') + '?' + $(this).fieldSerialize();

// @todo TinyMCE coupling
if(typeof tinyMCE != 'undefined') tinyMCE.triggerSave();

// Post the data to save
$.post(formAction, form.formToArray(), function(result){
// @todo TinyMCE coupling
tinymce_removeAll();

$('#right #ModelAdminPanel').html(result);

if($('#right #ModelAdminPanel form').hasClass('validationerror')) {
statusMessage(ss.i18n._t('ModelAdmin.VALIDATIONERROR', 'Validation Error'), 'bad');
} else {
statusMessage(ss.i18n._t('ModelAdmin.PROCESSED', 'Processed'), 'good');
}

// Is jQuery.live a solution?
Behaviour.apply(); // refreshes ComplexTableField
if(window.onresize) window.onresize();
}, 'html');

return false;
});

In CustomModelAdmin_RecordController:
function doProcess($data,$form,$request)
{
$this->currentRecord->doProcess();
$request['Processed'] = 1;
if(Director::is_ajax()) {
return $this->edit($request);
} else {
Director::redirectBack();
}

}
