Allows you to create a CMS button for creating and editing a single related object. It is actually a grid field, but just looks like a button.

👁 demo

Installation

composer require silvershop/silverstripe-hasonefield

Usage

 use SilverShop\HasOneField\HasOneButtonField;

 private static $has_one = [
 'Address' => 'Address'
 ];

 public function getCMSFields() {
 $fields = parent::getCMSFields();

 $fields->addFieldToTab("Root.Main",
 HasOneButtonField::create($this, "Address")
 );

 return $fields;
 }

You must pass through the parent context ($this), so that the has_one relationship can be set by the GridFieldDetailForm.

Filtering Results

To filter the results shown in the picker use HasOneAddExistingAutoCompleter::setSearchList.

$property = HasOneButtonField::create(
 $this,
 'Address'
);

$property
 ->getConfig()
 ->getComponentByType(HasOneAddExistingAutoCompleter::class)
 ->setSearchList(Property::get()->filter("Country", "GB"));

$fields->addFieldToTab(
 'Root.Main',
 $property
);
