PatchEntity 在 Cakephp 3.0 中忽略来自 ajax 请求的数据
PatchEntity ignore data from an ajax request in Cakephp 3.0
我经常使用 patchEntity
函数将我的实体与表单数据混合,它工作正常,即使有 ajax 请求。
但是,当我尝试从 ajax 请求中插入带有 JSON 数据的数据时,patchEntity 无法检索数据。
我的ajax要求很简单:
var rate = function (user, rate, success, error) {
$.ajax({
type: "POST",
url: baseUrl + 'rate/add',
data: {
id: this.id,
user: user.id
rate: rate
},
dataType: 'json',
success: success,
error: error
});
});
在我的速率控制器中,我的添加函数如下所示:
public function add()
{
if ($this->request->isAjax()) {
$this->layout = 'ajax';
$rate = $this->Rate->newEntity();
if ($this->request->is('post')) {
$rate = $this->Rate->patchEntity($rate, $this->request->data);
if ($rate->errors()) {
$this->set([
'status' => 500,
'message' => $rate->errors()
]);
} else {
if ($this->rate->save($rate)) {
$this->set([
'status' => 200
]);
} else {
$this->set([
'status' => 500,
'message' => $rate->errors()
]);
}
}
return $this->render('/Ajax/result');
}
}
这会引发异常:
Cannot insert row, some of the primary key values are missing. Got (,
, ), expecting (id, user)
我可以用这个代替 $this->Rate->patchEntity($rate, $this->request->data);
来保存我的数据
$rate['id'] = $this->request->data['id'];
$rate['user'] = $this->request->data['user'];
$rate['rate'] = $this->request->data['rate'];
我必须向 patchEntity
函数传递什么样的数组才能使它起作用?
感谢 ndm 的评论,我检查了 Rate Entity 并删除了由 bake 自动生成的这部分:
protected $_accessible = [
'rate' => true,
];
