updateOrCreate在Laravel Eloquent中不起作用

Question

我想更新或创建模型。它根本不起作用。

这是我的代码：

foreach ($ProfileRequest as $fieldname => $value){
    ProfileRequest::updateOrCreate(['sm_id' => $uid, 'field_name' => $fieldname],
        [
            'sm_id' => $uid,
            'field_name' => $fieldname,
            'value' => $value
        ]);
    }

这适用于插入：

 foreach ($ProfileRequest as $fieldname => $value) {
     $req = new ProfileRequest;
     $req->chef_id = $uid;
     $req->field_name = $fieldname;
     $req->value = $value;
     $req->save();
 }

Answer 1

由于您正在处理批量更新，因此需要在模型中指定可填写字段。把它放在你的模型上

protected $fillable = ['field_name','value'];

Answer 2

像这样更改你的代码

foreach ($ProfileRequest as $fieldname => $value){
    ProfileRequest::updateOrCreate(
        [
            'sm_id' => $uid
        ], 
        [
            'field_name' => $fieldname,
            'value' => $value
        ]
    );
}

避免重复这些字段。如果以某种方式，我的代码不适合你，请在这里检查自己的函数定义：https://laravel.com/api/5.4/Illuminate/Database/Eloquent/Builder.html#method_updateOrCreate

这有效

foreach ($ProfileRequest as $fieldname => $value){
    ProfileRequest::firstOrNew(array('sm_id' => $uid, 'field_name' => $fieldname));
            $chefReq->sm_id = $uid;
            $chefReq->field_name = $fieldname;
            $chefReq->value = $value;
            $chefReq->save();
}
