Easy to manage has_one relations with familiar link/unlink feature.

Introduction

Adds a Has-One type of field to allow you to create, link, unlink, delete, or edit DataObjects in a has_one relationship. Based on a gridfield, but without the fluff.

• "Create" button takes you to a new page, and from there the parent is updated with the new relation when the new object is saved.
• Gridfield-style "Link Existing" field is used to search and select existing objects, and happens inline/ajax.
• If there already is a relation, clicking on the data or the gridfield-style "Edit" icon take you to the usual edit page.
• Gridfield-style "Unlink" icon happens inline/ajax and writes the parent only.
• Gridfield-style "Delete" icon also happens inline/ajax with the "Are you sure" prompt.

Requirements

• Silverstripe 3x.

Installation

composer install

Manipulations

• Access the internal gridfield using $gridfield = $field->FieldList()->first();.
• Set the display fields using $gridfield->setDisplayFields($someArray);.
