Need help to use more than one DataObjectManager within a single FieldSet return?in
28 October 2010 at 12:58am
I am learning how to use the DataObjectManager module.
The followings are the 3 DataObjects (Data2,Data3,Data4) nested to one parent DataObject (Data1).
From the parent Data1 popup, I can only have access to one nested Dataobject e.g. Data2. I need suggestion to what I need to do to allow access to all the nested children dataobjects (Data2,Data3, and Data4). Thank you//Nested DataObjects
class Data2 extends DataObject {
static $db = array(
'Title'=>'Text',
'Description'=>'Text'
);
}
//Nested DataObjects
class Data3 extends DataObject {
static $db = array(
'Title'=>'Text',
'Description'=>'Text'
);
}
//Nested DataObjects
class Data4 extends DataObject {
static $db = array(
'Title'=>'Text',
'Description'=>'Text'
);
}class Data1 extends DataObject {
static $db = array(
'Name' => 'Text',
);static $has_many = array(
'Data2List' => 'Data2 ',
'Data3List' => 'Data3 ',
'Data4List' => 'Data4 '
);static $has_one = array(
'Data1List' => 'Data1Holder'
);function getCMSFields() {
$fieldListSymptomList = array();
return new FieldSet(
new TextField('Name', 'Data1 Name'),
new DataObjectManager($this, $Data2List, $Data2),
new DataObjectManager($this, $Data3List, $Data3),
new DataObjectManager($this, $Data4List, $Data4)
);
}}
class Data1Holder extends Page {
//put your code here
static $db = array(
);
static $has_many = array(
'Data1List' => 'Data1'
);
static $allowed_children = array('Data1');public function getCMSFields() {
$f = parent::getCMSFields();
$manager = new DataObjectManager(
$this, // Controller
'Data1List', // Source name
'Data1', // Source class
array('Name' => 'Data1 Name'), // Headings
'getCMSFields_forPopup' // Detail fields function or FieldSet
// Filter clause
// Sort clause
// Join clause
);$f->addFieldToTab("Root.Content.Data1", $manager);
return $f;
}
}This work, but when I uncommend all 3 DataObjectManager, I get an error during popup for Data1.
//class Data1
return new FieldSet(
new TextField('Name', 'Data1 Name'),
//new DataObjectManager($this, $Data2List, $Data2),
//new DataObjectManager($this, $Data3List, $Data3),
new DataObjectManager($this, $Data4List, $Data4)
);
