使用yml配置向现有供应商捆绑实体添加一个新字段

我正在尝试向供应商捆绑包中的现有实体添加多对一关联。

这是我在供应商捆绑包中的实体：-

class Post
{
    private $id;
    private $title;
    private $accroche;
    private $article;
    private $categories;
    private $comments;
    private $created;
    private $updated;
    private $publied;
}

这是供应商捆绑包中Post实体的orm映射文件：-

Mv'BlogBundle'Entity'AdminBlog'Post:
  type:                 entity
  table:                null
  repositoryClass:      Mv'BlogBundle'Entity'AdminBlog'PostRepository
  id:
    id:
      type:             integer
      generator:
        strategy:       AUTO
  fields:
    title:
      type:             string
      length:           150
    accroche:
      type:             text
    article:
      type:             text
    created:
      type:             datetime
      gedmo:
        timestampable:
          on: create
    updated:
      type:             datetime
      gedmo:
        timestampable:
          on: update
    publied:
      type:             datetime
  manyToMany:
    categories:
      targetEntity:   Mv'BlogBundle'Entity'AdminBlog'Category
      inversedBy:     posts
      joinTable:
        name:         post_category
        joinColumns:
          post_id:
            referencedColumnName: id
            onDelete:             CASCADE
        inverseJoinColumns:
          category_id:
            referencedColumnName: id
            onDelete:             RESTRICT
  oneToMany:
    comments:
      targetEntity:   Mv'BlogBundle'Entity'AdminBlog'Comment
      mappedBy:       post

我创建了供应商捆绑包的子捆绑包。我研究了mappedSuperclass，并尝试了其他继承方法。但他们中没有一个只是为"邮政"实体添加了一个关联。

我只想有如下的东西（尝试将其添加到orm映射文件中，但不起作用）：-

manyToOne:
  user:
    targetEntity:   TP'Bundle'MainBundle'Entity'User
    joinColumns:
        user_id:
          referencedColumnName: id
