Symfony中Doctrine对应的Mongodb数据类型 data type

1. hash 就是 json对象

2. collection 就是 数组

 

3. 若要知道如何使用referenceOne, referenceMany, embbedDocument等

主要查看：

http://doctrine-mongodb-odm.readthedocs.org/en/latest/reference/reference-mapping.html

http://docs.doctrine-project.org/projects/doctrine-mongodb-odm/en/latest/reference/embedded-mapping.html#embed-many

http://docs.doctrine-project.org/projects/doctrine-mongodb-odm/en/latest/reference/basic-mapping.html#doctrine-mapping-types

以上部分主要看yaml部分，就会知道如何编写 yml 了。

比较典型的yml：

 

Documents\User:
  fields:
    id:
      type: id
      id: true
    name:
      type: string
    email:
      type: string
  referenceMany:
    posts:
      targetDocument: Documents\BlogPost
      cascade: all

Documents\BlogPost:
  fields:
    id:
      type: id
      id: true
    title:
      type: string
    body:
      type: string
    createdAt:
      type: date
