13. Drupal 7 Entities
14. Custom Entities
15. Why Bother?
16. OOP
18. More Art Then Science
19. Reservations
20. hook_entity_info()
21. /** * Implements hook_entity_info(). */ function gc_reservation_entity_info() { return array( 'gc_reservation' => array( 'label' => t('Reservation'), 'plural label' => t('Reservations'), 'entity class' => 'GCReservation', 'controller class' => 'GCReservationController', 'base table' => 'gc_reservation', 'entity cache' => TRUE, 'entity keys' => array( 'id' => 'id', 'label' => 'id', ), 'label callback' => 'entity_class_label', 'uri callback' => 'gc_reservation_reservation_uri', 'fieldable' => TRUE, 'bundles' => array( 'gc_reservation' => array( 'label' => t('Reservation'), 'admin' => array( 'path' => 'admin/structure/reservations', 'access arguments' => array('administer reservation settings'), ), ), ), 'access callback' => 'gc_reservation_reservation_access', 'module' => 'gc_reservation', 'admin ui' => array( 'path' => 'admin/content/reservations', 'file' => 'gc_reservation.admin.inc', 'controller class' => 'GCReservationUIController', ), ), ); }
22. hook_entity_info() label access_callback admin_ui bundles base_table entity_class label_callback
23. Add Methods
24. class GCReservation extends Entity { }
25. class GCReservation extends GCChargeableEntity { }
26. class GCReservation extends GCChargeableEntity implements GCCreditable { }
27. Performance
28. base_table
29. Entity Tools
30. EntityFieldQuery
31. db_query
32. $ids = db_query("SELECT id FROM {gc_reservation} WHERE type = 'booking'") ->fetchCol();
33. db_select
34. $query = db_select('gc_reservation', 'gcr') ->fields('gcr', array('id')) ->condition('gcr.created', $created_limit, '>') ->condition('gcr.status', 1, '='); $query->innerJoin('field_reservation_type', 'rt', 'gcr.id = frt.entity_id'); $query->condition('frt.field_reservation_type_value', 'booking', '='); $result = $query->execute();
35. EntityFieldQuery
36. $query = new EntityFieldQuery(); $results = $query->entityCondition('entity_type', 'gc_reservation') ->fieldCondition('field_reservation_type', 'value', 'booking') ->propertyCondition('created', $created_limit, '<') ->propertyCondition('status', 1) ->addMetaData('account', user_load(1)); ->execute();
37. $query = new EntityFieldQuery(); $results = $query->entityCondition('entity_type', 'gc_reservation') ->fieldCondition('field_reservation_type', 'value', 'booking') ->propertyCondition('created', $created_limit, '<') ->propertyCondition('status', 1) ->addMetaData('account', user_load(1)); ->execute();
38. $query = new EntityFieldQuery(); $results = $query->entityCondition('entity_type', 'gc_reservation') ->fieldCondition('field_reservation_type', 'value', 'booking') ->propertyCondition('created', $created_limit, '<') ->propertyCondition('status', 1) ->addMetaData('account', user_load(1)); ->execute();
39. $query = new EntityFieldQuery(); $results = $query->entityCondition('entity_type', 'gc_reservation') ->fieldCondition('field_reservation_type', 'value', 'booking') ->propertyCondition('created', $created_limit, '<') ->propertyCondition('status', 1) ->execute();
40. EntityMetaDataWrapper
41. EMW
42. EMW Querying
43. if (!empty($node->field_event_photo_ref[$node->language][0]['target_id'])) { if ($imgrefnode = node_load($node->field_event_photo_ref[$node->language][0]['target_id'])) { // DO SOME STUFF. } }
44. $recipe_wrapper = entity_metadata_wrapper('node', $node); if ($image_node = $recipe_wrapper->field_ref_image->value()) { // DO SOME STUFF! }
45. $entity = $entity_wrapper->value();
46. $ref_entity = $entity_wrapper->field_ref->value();
47. $ref_wrapper = $entity_wrapper->field_ref();
48. $id = $entity_wrapper->getIdentifier();
49. $label = $entity_wrapper->label();
50. EMW Querying getIdentifier() getBundle() label() entityKey() value()
51. EMW Mutation
52. $entity_wrapper->status->set(0);
53. $entity_wrapper->field_collected->set(TRUE);
54. $entity_wrapper->field_img_ref->set($image_node);
55. Performance
56. Developer Experience (DX)
57. Hardware is Cheap
