Hi there,

I have two classes.

1) Postal Codes
2) Insurer

There exists a has_one relationship between the Insurer and Postal Codes and i only need back end functionality eg i only need to add/edit records via model admin.

The problem that i am sitting with is that there are 10 000 postal codes to choose from. Loading 10 000 records into a dropdown field does not work. I have set the system up in model admin and it works. I just need help figuring out how to do a ajax type search on the postal codes field. See existing code below:

class Insurer extends DataObject
{
static $db = array
(
'Name'=>'Varchar(100)',
'DateJoined'=>'Date',
'Tel'=>'Varchar(10)',
'Fax'=>'Varchar(10)',
'VatNo'=>'Varchar(10)',
'PostalAddress'=>'Text',
'IsActive'=>'Boolean(1)'
);

static $has_one = array(
'PostalCode'=>'PostalCodes',
);

function getCMSFields() {
$fields = new FieldList(
new TextField('Name','Company Name'),
$dateField = new DateField('DateJoined', 'DateJoined',date("Y-m-d")),
new TextField('Tel','Telephone Number'),
new TextField('Fax','Fax Number'),
new TextField('VatNo','Vat Number'),
new TextareaField('PostalAddress','Postal Address'),
new CheckboxField('IsActive', 'Is this insurer active?',1),
new DropdownField('PostalCode', 'Postal Code', PostalCode::get()->map('ID', 'Suburb')) /// How do i make this a ajax search
);
$dateField->setConfig('showcalendar', true);
$dateField->setConfig('dateformat','yyyy-MM-dd');
$dateField->setConfig('min','2012-01-01');

return $fields;
}

// Sets the sumary fields that will be displayed in teh grid field
static $summary_fields = array(
'Name',
'DateJoined',
'Tel',
'Fax'
);
