Custom entity erstellen mit dem Modul Inline Entity Form
Eingetragen von maen (547)am 04.09.2014 - 21:28 Uhr in
Hallo an alle,
ich beschäftige mich seit gestern mit dem Kreieren von custom entities, hartes Brot ehrlich gesagt.
Was ich nicht verstehe ist die Implementierung von Inline Entity Form, speziell dabei wie ich den oder die Controller einbaue.
Das Ziel ist es, eine entity mit vielen Spalten zu bauen, also nicht fieldable, der Performance wegen, und dann per entity reference mit inline entity form in eine node zu laden.
Also:
In der Readme von Inline Entity Form steht folgendes zu dem Thema:
Integrating with Inline Entity Form
-----------------------------------
An entity type can add support for this module by declaring the
inline entity form controller class in its entity info:
$entity_info['commerce_line_item']['inline entity form'] = array(
'controller' => 'CommerceLineItemInlineEntityFormController',
);
The controller needs to extend EntityInlineEntityFormController and at least
override entityForm() to provide a function entity form.
Meine Test Entity hat bisher folgendes Aussehen, wobei das ehrlich gesagt copy-paste ist:
function demo_entity_info() {
$info = array();
$info['project'] = array(
'label' => t('Project'),
'base table' => 'demo_projects',
'entity keys' => array(
'id' => 'id',
'label' => 'name',
),
'entity class' => 'ProjectEntity',
'controller class' => 'ProjectEntityController',
'access callback' => 'demo_access_callback',
'uri callback' => 'entity_class_uri',
'admin ui' => array(
'path' => 'admin/projects',
'controller class' => 'EntityDefaultUIController',
),
'views controller class' => 'EntityDefaultViewsController',
'module' => 'demo',
);
return $info;
}d.h. ich greife auf eine via hook_schema erstellte DB Tabelle namens demo_projects zu, erweitere die Klasse Entity des Systems mit ProjectEntity, so dass die URL zur Ansicht des jeweiligen Entitäteninhaltes verândert wird, erweitere die Klasse EntityApiController, die ich vom Modul Entity geschenkt bekommen habe, mittels ProjectEntityController um die Ansicht der Inhalte entsprechend anzupassen bzw. zu erweitern, und habe für die admin UI bzw für views jeweils 1 Controller.
Habe natürlich auch in den issues vom modul nach Erklärungen gesucht.
Da steht wie folgt:
Schau in der include vom Modul wie das für nodes gemacht ist, und hau in die hook_info folgendes rein:
<?php
$entity_info['inline entity form'] = array(
'controller' => 'YourEntityInlineEntityFormController',
);
?>Meine Frage somit: mit was erweitere ich demnach diese Klasse InlineEntityFormController, die Erweiterung hiesse ja dann ProjectInlineEntitwFormController.
Aber was schreibe ich in die extension? hat das schon jemand mal gemacht???
Danke vorab, hier mein demo Code komplett:
