CakePHP保存失败，并设置了验证错误，但为空 [英] CakePHP save failing with validation errors set but empty

问题描述

我同时使用TranslateBehavior和TreeBehavior的模型无法保存。我怀疑这与这些行为之一有关。这是要输入的数据：

A model that I am using with both TranslateBehavior and TreeBehavior is failing to save. I suspect it is something to do with one of these behaviors. Here's the data going in:

array(
    'Category' => array(
        'id' => '3252',
        'parent_id' => null,
        'sort_order' => '0',
        'name' => array(
            'eng' => 'english name',
            'fra' => 'french name',
            'deu' => 'german name',
            'ita' => 'italian name',
            'spa' => 'spanish name'
        ),
    )
)

和 $ this-> Category-> validationErrors 是：

array(
    'parent_id' => array(),
    'sort_order' => array()
)

模型中未定义验证规则。没有定义beforeSave（）或beforeValidate（）方法。

There are no validation rules defined in the model. There is no beforeSave() or beforeValidate() method defined.

我没有在屏幕上显示任何验证错误，尽管所有字段都有红色的错误轮廓。

I am not getting any validation errors displayed on screen, although all fields have the red "error" outline.

编辑-保存操作未达到Category :: beforeSave（）的程度。我创建了该函数，但该函数无法运行。

Edit - the save operation is not getting as far as Category::beforeSave(). I created that function and it does not get run. It gets as far as Category::beforeValidate().

        $validates = $this->Category->validates($this->request->data);
        debug($validates);
        $saved = $this->Category->saveAll($this->request->data);
        debug($saved);

在上面的代码中， $ validates 为是的， $ saved 是错误的。在上述过程中的任何时候都不会调用类别beforeSave。验证似乎在调用saveAll（）时失败。我需要使用saveAll而不是保存一次保存所有翻译（我在其他地方使用其他模型也没有问题）。

In the above code, $validates is true, $saved is false. Category beforeSave is not called at any point in the above process. The validation seems to fail on the call to saveAll(). I need to use saveAll rather than save to save all translations at once (I am doing this elsewhere with another model with no problems).

推荐答案

因此，经过一段时间的调试后，我发现了问题所在：

So, after a while debugging I have found the problem:

   public $hasMany = array(
      'Category' => array('className' => 'Category', 'foreignKey' => 'parent_id', 'counterCache' => true),
      ...

我不知道为什么写这个-我应该知道这会引起问题，我想我打算写...

I have no idea why I wrote this - I should have been aware that it was going to cause problems, I think I meant to write...

     public $hasMany = array(
        'Children' => array('className' => 'Category', 'foreignKey' => 'parent_id', 'counterCache' => true),
        ...

无论如何，将其更改为后者，这些错误已消失。

Anyway, changed it to the latter and these errors have gone.
