我使用 phpMyAdmin 创建了我的数据库和表。我也在那里建立了关系。

然后我想通过执行以下命令让 Doctrine 2 为我创建 YAML 文件：

php 学说 orm:convert-mapping --from-database yml /path/to/fixtures/schema

它创建了 *.dcm.yml 文件，看起来还不错。所以我需要通过这样做来制作实体：

php 学说 orm:generate-entities /path/to/models

但是，我收到此错误：

[Doctrine\ORM\Mapping\MappingException] 类调用者\dcm 不是有效的实体或映射的超类。

我添加了 -v 标志并得到了这个：

我试图让 Doctrine 2 作为 Kohana 的一个模块来处理 MySQL 关系。以为我会从让 Doctrine 工作开始，因为这确实是更难的部分。

这是它创建的 YAML 文件：

Callers:
  type: entity
  table: callers
  fields:
    id:
      id: true
      type: integer
      unsigned: false
      nullable: false
      generator:
        strategy: AUTO
    firstname:
      type: string
      length: 75
      fixed: false
      nullable: true
    lastname:
      type: string
      length: 75
      fixed: false
      nullable: true
    company:
      type: string
      length: 75
      fixed: false
      nullable: true
    email:
      type: string
      length: 150
      fixed: false
      nullable: true
    datecreated:
      type: datetime
      nullable: false
    dateupdated:
      type: datetime
      nullable: false
    address1:
      type: string
      length: 150
      fixed: false
      nullable: true
    address2:
      type: string
      length: 150
      fixed: false
      nullable: true
    city:
      type: string
      length: 100
      fixed: false
      nullable: true
    state:
      type: string
      length: 50
      fixed: false
      nullable: true
    zip:
      type: string
      length: 10
      fixed: false
      nullable: true

那么出了什么问题呢？

我刚刚发生了类似的错误。确保您的 .dcm.yml 文件名为 Callers.dcl.yml 而不是 callers.dcl.yml。大写的第一个字母很重要，并且必须与您的班级名称相匹配。
