how to make scaffolding show has_many as dropdown?
23 May 2008 at 5:04am Last edited: 23 May 2008 5:12am
I was going through tutorial #5, and decided that I would like to see if the admin panel scaffolding could easily show a dropdown of choices when presented with a has_many datamodel relationship.
So I decided to make Student has_many Nationality, and promote nationality from a simple text field to a database object. Then I found a class called "DropdownField_withAdd"... and got so far as to having the "Add Student" popup link in the CMS display a dropdown called "Nationality"... but of course the dropdown is empty, and I don't see a way to get it to give me the option of creating new nationalities....
Here's the relevant code I created:
class Student extends DataObject {
static $db = array(
'FirstName' => 'Text',
'LastName' => 'Text'
);static $has_one = array(
'Mentor' => 'Mentor',
'Nationality' => 'Nationality'
);public function getCMSFields_forPopup(){
$fields = new FieldSet();
$fields->push(new TextField('FirstName', 'First Name'));
$fields->push(new TextField('LastName', 'Last Name'));$Nationalities = Nationality::get('Nationality');
$Nationalities_array = array();
if ($Nationalities)
foreach ($Nationalities as $Nationality)
$Nationalities_array[$Nationality->getField('ID')]
= $Nationality->getField('Nationality');$fields->push(
new DropdownField_withAdd(
'Nationality',
'Nationality',
$Nationalities_array,
'addLink'
)
);return $fields;
}}
-------------------------------------
class Nationality extends DataObject {
static $db = array(
'Nationality' => 'Text'
);public function getCMSFields_forPopup(){
$fields = new FieldSet();
$fields->push(new TextField('Nationality', 'Nationality'));
return $fields;
}}
