hi guys,

i read in one of old topic to create json from dataobject is with this function :
$f = new JSONDataFormatter();
return $f->convertDataObject($myDataObject);

but it's not working, it gave me this error :
[User Error] Uncaught Exception: Object->__call(): the method 'inheriteddatabasefields' does not exist on 'DataObjectSet'

Please someone tell me the correct way to create json format from DataObject

Hmm can you post your full code and the full backtrace of the error. Seems a bit weird that a method is being called on a 'DataObjectSet' if your performing a function on dataobject.

$data = DataObject::get("TABLE","WHERE");
$f = new JSONDataFormatter();
return $f->convertDataObject($data);

It seem like the problem is the JSONDataFormatter is only work for single dataobject, if i select the dataobject using get_one or get_by_id it's working, but what i want to achieve is to hv more than one data as JSON.

Is there anything i can do?

Just for anyone that stumbles across this and wants the answer.

You have to use convertDataObjectSet($dos) on a dataobjectset. convertDataObject is just for a single DataObject.

Thanks for your help! I can now pass a JSON object to the flash.swf, really handy.

But a problem still exists: only displays with the variables from the TextFeldangabe table when I'm logged in the backend. Would there be a possibility to log in a readonly user automatically in the controller or something like that??

class TextFeldPage_Controller extends Page_Controller {

           public function jsonausgabe() {
           $data1 = DataObject::get("TextFeldangabe","TextFeldangabe.Titel='$this->URLSegment'");
           $f1 = new JSONDataFormatter();
           return $f1->convertDataObjectSet($data1);


Thanks for your help mates!!!
