Indirect modification of overloaded property has no effect
提问by
When I run the below API I got this error
当我运行以下 API 时出现此错误
"Indirect modification of overloaded property App\User::$attendance has no effect".
“间接修改重载属性 App\User::$attendance 无效”。
I still cannot figure it out for so long. Could you please someone help me on this.
这么久我还是想不通。你能请人帮助我吗？
public function apiPresent( $id, Request $request )
{
$tokenuser = User::with('attendance')
->where('token', $request->input('token'))->first();
$present = $request->input('present');
$user = User::with('attendance')->find($id);
if( $user && $tokenuser == $user )
{
$user->attendance->present = $present;
$user->attendance->date = Carbon::now()->format('d-m-Y');
$user->attendance->time = Carbon::now()->format('H-i');
$user->attendance->save();
return response()->json([
'status' => 'Ok',
'message' => 'Present Changed',
'Present' => $user->attendance->present
]);
}
else
{
return response()->json([
'status' => 'Fail',
'message' => 'Your state does not changed'
]);
}
}

If i understand your problem. You are saving the attendance.
如果我理解你的问题。您正在节省出勤率。
Try this:
尝试这个：
use App\Attendance; // Add before controller declaration
public function apiPresent( $id, Request $request )
{
$tokenuser = User::where('token', $request->input('token'))->first();
$present = $request->input('present');
$user = User::find($id);
if( $user && $tokenuser->id == $user->id ){
$attendance = new Attendance;
$attendance->present = $present;
$attendance->date = Carbon::now()->format('d-m-Y');
$attendance->time = Carbon::now()->format('H-i');
$attendance->save();
return response()->json([
'status' => 'Ok',
'message' => 'Present Changed',
'Present' => $present
]);
}
else {
return response()->json([
'status' => 'Fail',
'message' => 'Your state does not changed'
]);
}
}
Hope it helps!
希望能帮助到你！

I think the problem is that you're trying to directly assign to a relation of App::User. Your code segment highlights this:
我认为问题在于您试图直接分配给App::User. 您的代码段突出显示了这一点：
if( $user && $tokenuser->id == $user->id ){
$user->attendance->present = $present;
$user->attendance->date = Carbon::now()->format('d-m-Y');
$user->attendance->time = Carbon::now()->format('H-i');
$user->attendance->save();
...
In Eloquent, you access a relation as a property using the magic __get()method, which returns a copyof the object.
在 Eloquent 中，您可以使用魔术__get()方法将关系作为属性访问，该方法返回对象的副本。
When you're trying to assign any value to any of the relation's property (in this case $user->attendance), it will not have any effect on the original object at all, hence the warning.
当您尝试为任何关系的属性（在本例中为 $user->attendance）分配任何值时，它根本不会对原始对象产生任何影响，因此会发出警告。
You can fix this by creating new object instance and add it to createmethod, like this:
您可以通过创建新对象实例并将其添加到create方法来解决此问题，如下所示：
$attendance = new Attendance();
$attendance->present = $present;
$attendance->date = Carbon::now()->format('d-m-Y');
$attendance->time = Carbon::now()->format('H-i');
$user->attendance->create($attendance);
This will save the new record with the foreign key.
这将使用外键保存新记录。

In my case
就我而言
Laravel php 5.7 & Mysql 5.7 The Error which i got for the following code is Indirect modification of overloaded property Illuminate\Http\Request::${
Laravel php 5.7 和 Mysql 5.7 我为以下代码得到的错误是对重载属性 Illuminate\Http\Request::${ 的间接修改
Error code
错误代码
$config->name = $request->title;
$config->lead_by_id = $request->owner;
$config->tech_stack = $request->stack;
$config->is_POC = $request->
$config->updated_by = $request->
$config->start_date = $request->start_date;
$config->end_date = $request->end_date;
Then i found that i have not set the request variable properly
然后我发现我没有正确设置请求变量
Fix
使固定
$config->name = $request->title;
$config->lead_by_id = $request->owner;
$config->tech_stack = $request->stack;
$config->is_POC = $request->poc;
$config->updated_by = $request->$user->id;
$config->start_date = $request->start_date;
$config->end_date = $request->end_date;
