Question

我和Jobeet一起学习Symfony和Doctrine。我想添加一些修改。默认是： http://www.symfony-project.org/jobeet/1_4/Doctrine/en/03

JobeetCategory:
  actAs: { Timestampable: ~ }
  columns:
    name: { type: string(255), notnull: true, unique: true }

JobeetJob:
  actAs: { Timestampable: ~ }
  columns:
    category_id:  { type: integer, notnull: true }
 (...)
  relations:
    JobeetCategory: { onDelete: CASCADE, local: category_id, foreign: id, foreignAlias: JobeetJobs }

如果我去表格（创造新的），我有： http://www.symfony-project.org/images/jobeet/1_4/03/job.png

类别ID - 选择列表

// BaseJobeetJobForm.class.php：

 'category_id'  => new sfWidgetFormDoctrineChoice(array('model' => $this->getRelatedModelName('JobeetCategory'), 'add_empty' => false)),

// sfFormDoctrine.class.php：

  protected function getRelatedModelName($alias)
  {
    $table = Doctrine_Core::getTable($this->getModelName());

    if (!$table->hasRelation($alias))
    {
      throw new InvalidArgumentException(sprintf('The "%s" model has to "%s" relation.', $this->getModelName(), $alias));
    }

    $relation = $table->getRelation($alias);

    return $relation['class'];
  }

我该怎么做：

JobeetCategory:
  actAs: { Timestampable: ~ }
  columns:
    name: { type: string(255), notnull: true, unique: true }
    nametwo: { type: string(255), notnull: true, unique: true }

JobeetJob:
  actAs: { Timestampable: ~ }
  columns:
    category_id:  { type: integer, notnull: true }
    nametwo_id:  { type: integer, notnull: true }
 (...)
  relations:
        JobeetCategory: { onDelete: CASCADE, local: category_id, foreign: id, foreignAlias: JobeetJobs } 
JobeetCategory: { onDelete: CASCADE, local: nametwo_id, foreign: id, foreignAlias: JobeetJobsTwo }

我怎么能以“nametwo”的形式出现？我将有两个列表选择（category_id（已经）和nametwo_id：）

您想在jobeetjob和jobeetcategory之间设置两个截然不同的关系你必须清楚地命名这种关系，如下所示：

    JobeetJob:   
     actAs: { Timestampable: ~ }  
     columns:
       category_id:  { type: integer, notnull: true }
       nametwo_id:  { type: integer, notnull: true }  (...)   
     relations:
       JobeetCategoryOne: 
         class: JobeetCategory
         onDelete: CASCADE
         local: category_id
         foreign: id
         foreignAlias: JobeetJobs  
       JobeetCategoryTwo: 
         class: JobeetCategory
         onDelete: CASCADE
         local: nametwo_id, foreign: id,
         foreignAlias: JobeetJobsTwo

得到两列关系
