Question

我正在使用cakephp 2.x，我希望从我的模型中获取某个元素作为字段。问题出在我的结构上。如果我使用find all，那么我接受这个：

array(9) {
  [0]=> ...
  [1]=>
  array(7) {
    ["Person"]=>
    array(18) {
      ["id"]=>
      int(2)
      ["imie"]=>
      string(6) "STEFAN"

        ["objectTypeIdWithId"]=>
        string(3) "2_3"
        ["PeopleObk"]=>
        array(3) {
          ["id"]=>
          int(2)
          ["person_id"]=>
          int(3)
          ["obk_id"]=>
          int(3)
        }
      }
    }
  }

我想要检索Person.id，Person.displayName和Obk.0.id.首先是两个没有问题，但是当我尝试获取Obk.0.id时我得到错误：SQLSTATE [42P01]：未定义的表：7错误：表Obk缺少FROM。

我怎么能得到这样的东西？我想稍后在编码中设置值，但它会阻止我的工作。

在CakePHP 2中，您可以使用find()选项指定fields查询返回的字段，如： -

$this->Foo->find('all', [
    'fields' => ['Foo.id', 'Foo.name']
]);

这也适用于具有belongsTo或hasOne关系的所包含模型： -

$this->Foo->find('all', [
    'fields' => ['Foo.id', 'Foo.name', 'Bar.name'],
    'contain' => ['Bar']
]);

但是，如果包含的模型是hasMany或HABTM关系，则需要在包含中指定该模型的字段： -

$this->Foo->find('all', [
    'fields' => ['Foo.id', 'Foo.name'],
    'contain' => [
        'Bar' => ['fields' => 'Bar.name']
    ]
]);

这是因为CakePHP将执行多个SQL查询，因此包含需要为相关模型运行查询的参数。
