在CakePhp中调用unbindModel。它是如何工作的？ [英] unbindModel call in CakePhp. How does it work?

问题描述

unbindModel如何在蛋糕中发生？

How does unbindModel happen in cake?

$this->User->unbindModel(array('hasAndBelongsToMany' => array('Friend')));

我在函数的开头写了这个。但仍然查询朋友模型。在函数的中间有一个对paginate（）的调用。所以我认为分页器可能会产生查询。

I wrote this in the beginning of a function. But still it queries the 'Friend' model. There was a call to paginate() in the middle of the function. So I thought the paginator might be generating the queries.

我在paginate之前添加了一个unbindModel调用，现在可以正常工作。

I did added an unbindModel call just before paginate and it now works.

$this->User->unbindModel(array('hasAndBelongsToMany' => array('Friend')));
$user = $this->paginate("User", array("User.first_name LIKE" => $user["User"]["first_name"]));

unbindModel是否解除绑定每个查询？或者在整个函数调用期间解除绑定？

Does unbindModel unbind every query? or does it unbind during the entire function call?

推荐答案

从手册：

除非第二个参数设置为 false ，使用bind-和unbindModel（）删除或添加关联只适用于下一个模型操作。如果第二个参数设置为 false ，绑定将保留在请求的剩余部分。

Removing or adding associations using bind- and unbindModel() only works for the next model operation unless the second parameter has been set to false. If the second parameter has been set to false, the bind remains in place for the remainder of the request.

换句话说，在你 paginate（）或 find（）否则与模型，解除绑定将被逆转。

In other words, after you paginate() or find() or do anything else with the model, the unbinding will be reversed.
