我如何让symfony看到我表之间的新关系?

我正在使用symfony 1.4进行项目(已经开始),现在我正在更改一些东西,当我查询两个表之间的一些信息时,我得到一个关系错误,一个已经存在,另一个是新的,应该有一个指向第一个表的外键。

我收到类似这样的错误消息

exception 'Doctrine_Table_Exception' with message 'Unknown relation alias ' in /var/www/testorange/symfony/lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/vendor/doctrine/Doctrine/Relation/Parser.php:237 

Stack trace: #0 /var/www/testorange/symfony/lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/vendor/doctrine/Doctrine/Relation/Parser.php(235): Doctrine_Relation_Parser->getRelation('', false)

...

还有很多错误。

所以,我认为是因为我的表在symfony中的定义上还没有正确的关系(它们已经与我的数据库相关)。

我将此行添加到schema.yml然后[UPDATED]

 OhrmTrainningSubmit:
  connection: doctrine
  tableName: ohrm_trainning_submit
  columns:
    id_trainning_submit:
      type: integer(4)
      fixed: false
      unsigned: false
      primary: true
      autoincrement: true
    trainning:
      type: integer(4)
      fixed: false
      unsigned: false
      primary: false
      notnull: true
      autoincrement: false
    trainning_detail:

    answer:

      autoincrement: false
    state:
      type: integer(1)

      default: '0'
      notnull: true
      autoincrement: false
    user:
      type: integer(4)
      fixed: false
      unsigned: false
      primary: false
      notnull: true
      autoincrement: false
  relations:
    OhrmUser:
      local: user
      foreign: emp_number
      type: many
    OhrmTrainning:
      local: trainning
      foreign: id_trainning
      type: many

这是OhrmUser的定义

OhrmUser:
  connection: doctrine
  tableName: ohrm_user
  columns:
    id:
      type: integer(4)
      fixed: false
      unsigned: false

    emp_number:

      autoincrement: false
    user_name:

      autoincrement: false
    user_password:

      notnull: true
      autoincrement: false
    date_entered:
      type: timestamp(25)
      fixed: false
      unsigned: false
      primary: false
      notnull: false
      autoincrement: false
    date_modified:
      type: timestamp(25)
      fixed: false
      unsigned: false
      primary: false
      notnull: false

    created_by:
      type: integer(4)
      fixed: false
      unsigned: false
      primary: false
      notnull: false
      autoincrement: false
  relations:
    HsHrEmployee:
      local: emp_number
      foreign: emp_number
      type: one
    OhrmUserRole:
      local: user_role_id
      foreign: id
      type: one
    HsHrMailnotifications:
      local: id
      foreign: user_id
      type: many
    OhrmLeaveAdjustment:
      local: id
      foreign: created_by_id
      type: many
    OhrmLeaveComment:
      local: id
      foreign: created_by_id
      type: many
    OhrmLeaveEntitlement:
      local: id
      foreign: created_by_id
      type: many
    OhrmLeaveRequestComment:
      local: id
      foreign: created_by_id
      type: many
    OhrmTimesheetActionLog:
      local: id
      foreign: performed_by
      type: many

在我想要引用的表上,将引用的字段是“用户”到表“OhrmUser”到字段emp_number(我认为应该这样正确),问题是仍然是同样的错误,有没有人知道这个?我还应该做些什么?

我添加后,我运行

php symfony cc
php symfony doctrine:build-model
php symfony orangehrm:publish-assets
php symfony cc

查询

try{
$q = Doctrine_Query::create()
 ->select('*')
->from('OhrmTrainningSubmit TS')
->innerJoin('TS.OhrmUser U')
->addWhere("TS.trainning = $training")
->andWhere("TS.user = $employee");
$result = $q->execute();
    return $result;
}catch(Exception $e){
    print_r ($e->getMessage());
    return null;
}

我只能访问OhrmTrainningSubmit的数据,但是当我尝试访问User的某个字段时,我会收到内部错误。

我在此代码中收到错误

foreach ($detail as $det){
    echo $det['answer']; // This is printed with no problem
    //echo $det['user_name']; <-- this one comes from the table OhrmUser, I get server error with this one
}

其中$ detail是带有查询返回值的变量。

当我做

->select('TS.*, U.*')

我得到了其他错误,即

  

未知属性emp_number

任何想法?

提前致谢。

答案 0 :(得分:1)

两件事:

  1. 在您的架构中,确保在关系附近有正确的缩进:

      autoincrement: false
    relations:
      OhrmUser:
        local: user
        foreign: emp_number
        type: many
    
  2. 查询应如下所示:

    $q = Doctrine_Query::create()
        ->from('TrainningSubmit T')
        ->innerJoin('T.OhrmUser U')
        ->where('T.id_trainning = ?', $id);
    
  3. 当您在学说中指定联接时,您必须告诉ORM关系来自何处 - 因此T.OhrmUser U而不是OhrmUser U。这告诉我们您正在使用OhrmUser模型中的T关系。

    你使用->where()两次是错误的,因为第二个覆盖了第一个错误。如果要添加多个->andWhere()条件,则应使用->orWhere()where。然而,在处理学说中的命名关系时,你不必明确告诉doctrine它应该在哪些列上进行连接 - 它已经知道这要归功于模式文件。

    此外,如果您需要扩展联接条件,您可以使用WITH轻松完成,例如

     ->join('T.OhrmUser U WITH U.name LIKE ?', 'Michal')
    

    将翻译为:

     JOIN OhrmUser U ON U.emp_number = T.user AND U.name LIKE 'Michal'
    

    修改

    要从对象中检索数据,请使用:

    //if you return a plain array as a result of the query:
    echo $det['answer'];
    echo $det['OhrmUser']['user_name'];
    
    //if you return an array of objects:
    echo $det->getAnswer();
    echo $det->getOhrmUser()->getUserName();
