我正在尝试在 ZF2 和 Doctrine 2 中使用类表继承。我的实现非常简单。我想我已经设置好了类结构，但我认为某处的某些设置可能存在问题。不幸的是，我找到了很多关于类设置的文档，但没有找到很多关于 YML 实现的文档。每个人似乎都求助于使用教义工具来生成一切。就事物的设置方式而言，使用学说工具有点问题，尤其是在使用 ZF2 时。另外，我认为这是一个学习机会。所以，这就是我所拥有的：

当前问题：我没有从子类/表中获取任何数据：

.array(1) {
[0] =>
class MyCompany\Domain\Model\Customer\CustomerNote#2852 (9) {
  protected $customer =>
  NULL
  protected $note =>
  string(13) "Clever Note 1"
  protected $id =>
  string(1) "1"
  protected $disabled =>
  NULL
  protected $modified =>
  class DateTime#2884 (3) {

    ...

通用注释类/表：

CREATE TABLE generic_notes
(
  note_id serial NOT NULL,
  discriminator character varying(255) NOT NULL, 
  note text,
  created timestamp with time zone NOT NULL DEFAULT now(),
  created_by_id bigint NOT NULL,
  modified timestamp with time zone,
  modified_by_id bigint,
  disabled timestamp with time zone NOT NULL DEFAULT 'infinity'::timestamp with time zone,
  CONSTRAINT generic_notes_pkey PRIMARY KEY (note_id),
  CONSTRAINT generic_notes_created_by_id_fkey FOREIGN KEY (created_by_id)
      REFERENCES users (user_id) MATCH SIMPLE
      ON UPDATE CASCADE 
      ON DELETE RESTRICT,
  CONSTRAINT generic_notes_modified_by_id_fkey FOREIGN KEY (modified_by_id)
      REFERENCES users (user_id) MATCH SIMPLE
      ON UPDATE CASCADE 
      ON DELETE RESTRICT
)

客户备注类/表（继承通用备注）：

CREATE TABLE customer_notes
(
  note_id bigint NOT NULL,
  customer_id bigint NOT NULL,
  CONSTRAINT customer_notes_pkey PRIMARY KEY (note_id),
  CONSTRAINT customer_notes_note_id_fkey FOREIGN KEY (note_id)
      REFERENCES generic_notes (note_id) MATCH SIMPLE
      ON UPDATE RESTRICT 
      ON DELETE RESTRICT,
  CONSTRAINT customer_notes_customer_id_fkey FOREIGN KEY (customer_id)
      REFERENCES customers (customer_id) MATCH SIMPLE
      ON UPDATE R1ESTRICT 
      ON DELETE RESTRICT
)

以上所有内容都是完全有效且有效的。看来我没有为客户笔记单元测试包括我的笔记夹具数据，反之亦然。所以，为了我自己的愚蠢，几天都陷入了困境。
