CakePHP 3.x：更新多条记录

Question

我已阅读Saving Entities和Patching HasMany and BelongsToMany，但我遇到patchEntities（）问题，因为它似乎没有合并数据。修补后，$ entities的结果是1'空'/'新'记录而不是包含id的2。保存实体会导致外键错误。

我是CakePHP 3.0的新手，所以我可能在这里做错了。有人能帮助我吗？

谢谢！

我的代码：

if ($this->request->is(['patch', 'post', 'put'])) {
    $list = $this->RecipyIngredients->find()
        ->contain(['Ingredients', 'Quantities'])
        ->where(['RecipyIngredients.recipy_id' => $recipy_id])
        ->toArray();

    $entities = $this->RecipyIngredients->patchEntities($list, $this->request->data);

    debug($entities);
    foreach ($entities as $entity) {
        //$this->RecipyIngredients->save($entity);
        //debug($entity);
    }
}

各种结果：

debug($this->request->data);
[
    'RecipyIngredients' => [
        (int) 0 => [
            'id' => '1',

Answer 1

好的，查看来源，问题在于表名在$this->request->data中。

我将patchEntities（）行更改为：

$entities = $this->RecipyIngredients->patchEntities($list, $this->request->data['RecipyIngredients']);

一切都很好！
