php - 蛋糕PHP 3 : how to get all associations of a table?

Question

那是我的表对象的 var_dump():

object(App\Model\Table\BairrosTable)[117]
  public 'registryAlias' => string 'Bairros' (length=7)
  public 'table' => string 'bairros' (length=7)
  public 'alias' => string 'Bairros' (length=7)
  public 'entityClass' => string 'App\Model\Entity\Bairro' (length=23)
  public 'associations' => 
    array (size=4)
      0 => string 'regioes' (length=7)
      1 => string 'cidades' (length=7)
      2 => string 'clientes' (length=8)
      3 => string 'areas' (length=5)
  public 'behaviors' => 
    array (size=0)
      empty
  public 'defaultConnection' => string 'default' (length=7)
  public 'connectionName' => string 'default' (length=7)

我只想获取属性关联的数组，但是如果我尝试 $this->_table()->associations() ，我在 protected 变量上得到了一个带有 itens 的对象:

object(Cake\ORM\AssociationCollection)[205]
  protected '_items' => 
    array (size=4)
      'regioes' => 
        object(Cake\ORM\Association\BelongsTo)[206]
          protected '_validStrategies' => 
            array (size=2)
              ...
          protected '_name' => string 'Regioes' (length=7)
          protected '_className' => null
          protected '_bindingKey' => null
          protected '_foreignKey' => string 'regiao_id' (length=9)
          protected '_conditions' => 
            array (size=0)
              ...
          protected '_dependent' => boolean false
          protected '_cascadeCallbacks' => boolean false
          protected '_sourceTable' => 
            object(App\Model\Table\BairrosTable)[117]

          protected '_targetTable' => null
          protected '_joinType' => string 'INNER' (length=5)
          protected '_propertyName' => null
          protected '_strategy' => string 'join' (length=4)
          protected '_finder' => string 'all' (length=3)
          protected '_tableLocator' => null
      'cidades' => 
        object(Cake\ORM\Association\BelongsTo)[193]
          protected '_validStrategies' => 
            array (size=2)
              ...

          protected '_finder' => string 'all' (length=3)
          protected '_tableLocator' => null

          protected '_sort' => null

那么，如何获得一个包含表的所有关联的数组？

Answer 1

解决了。 $this->_table()->associations()是 \Cake\ORM\AssociationCollection目的。所以我使用 keys()获取关联数组的方法。
