Doctrine2使用PostgreSQL的ManyToMany关系：“SQLSTATE [42P01]：未定义的表：7错误：关系不存在”

Question

当我在两个实体之间进行INNER JOIN（由ManyToMany关系连接）doctrine说找不到关系machine_table_for_base_model：SQLSTATE[42P01]: Undefined table: 7 ERROR: the relation "machine_table_for_base_model" does not exist。为什么会发生？

我有一个associative table定义如下：

<!-- language: lang-sql --> 

CREATE TABLE machine_table_for_base_model ( 
    id_machine_table integer NOT NULL, 
    id_base_model integer NOT NULL, 
); 

ALTER TABLE ONLY machine_table_for_base_model 
    ADD CONSTRAINT machine_table_for_base_model_pkey PRIMARY KEY (id_machine_table, id_base_model); 

ALTER TABLE ONLY machine_table_for_base_model 
    ADD CONSTRAINT machine_table_for_base_model_ibfk_1 FOREIGN KEY (id_machine_table) REFERENCES machine_table(id) ON UPDATE CASCADE DEFERRABLE INITIALLY DEFERRED; 

ALTER TABLE ONLY machine_table_for_base_model 
    ADD CONSTRAINT machine_table_for_base_model_ibfk_2 FOREIGN KEY (id_base_model) REFERENCES base_model(id) ON UPDATE CASCADE DEFERRABLE INITIALLY DEFERRED; 

当我执行关联表的学说映射我有类似的东西：

Package\MyBundle\Entity\MachineTable: 
    type: entity 
    schema: techguide 
    table: machine_table 
    indexes: 
     IDX_8386B61E3C5569AA: 
      columns: 
       - edit_user 
    id: 
     id: 
      type: integer 
      nullable: false 
      options: 
       unsigned: false 
      id: true 
      generator: 
       strategy: SEQUENCE 
    fields: 
     description: 
      type: string 
      nullable: false 
      length: 200 
      options: 
       fixed: false 
     labelsDimensions: 
      type: text 
      nullable: false 
      length: null 
      options: 
       fixed: false 
      column: labels_dimensions 
     editDate: 
      type: datetime 
      nullable: false 
      options: 
       default: now 
      column: edit_date 
    manyToOne: 
     editUser: 
      targetEntity: Package\SupportBundle\Entity\Account 
      cascade: { } 
      fetch: LAZY 
      mappedBy: null 
      inversedBy: null 
      joinColumns: 
       edit_user: 
        referencedColumnName: id 
      orphanRemoval: false 
    manyToMany: 
     idBaseModel: 
      targetEntity: BaseModel 
      cascade: { } 
      fetch: LAZY 
      mappedBy: null 
      inversedBy: idMachineTable 
      joinTable: 
       name: machine_table_for_base_model 
       joinColumns: 
        - 
         name: id_machine_table 
         referencedColumnName: id 
       inverseJoinColumns: 
        - 
         name: id_base_model 
         referencedColumnName: id 
      orderBy: null 
    lifecycleCallbacks: { }

最后我找到了解决这一问题。你需要（手动）编辑的ORM配置，这在我的情况是一个YAML文件joinTable名称，加入的Postgres模式中的关联表属于：

Entity.orm.yml

manyToMany: 
    idBaseModel: 
     targetEntity: BaseModel 
     cascade: { } 
     fetch: LAZY 
     mappedBy: null 
     inversedBy: idMachineTable 
     joinTable: 
      name: <NAME_OF_YOUR_SCHEMA>.<NAME_OF_THE_TABLE> 
      joinColumns: 
       - 
        name: id_machine_table 
        referencedColumnName: id 
      inverseJoinColumns: 
       - 
        name: id_base_model 
        referencedColumnName: id 
     orderBy: null 
lifecycleCallbacks: { }
