【解决方案1】：

$new_spent_time->spent_time = $new_spent_time::where('task_category',$task_category)
                                    ->sum('daily_spent_time', $new_spent_time->daily_spent_time , $fromDate);
$request['spent_time'] = (int)$new_spent_time->spent_time + $spent_time->daily_spent_time;

$new_spent_time->percentage = $new_spent_time::where('task_category',$spent_time->task_category)
                                    ->sum('daily_percentage', $new_spent_time->daily_percentage, $fromDate);
$request['percentage'] = (int)$new_spent_time->percentage  + $spent_time->daily_percentage;

【解决方案2】：

$task_category 是否在 "%$task_category%" 数组中？

如果是这样，则会导致错误，因为数组不能放入%。

这可能是 laravelc Like with array value

的解决方案

【解决方案3】：

您无法返回更新后的查询，因此请尝试

return $spent_time->fresh();

然后错误仍然存在添加为

return $spent_time->fresh()->toArray();

【讨论】：

@Lianurfadilah 我找不到你？那你能解释一下吗
你可以看到stackoverflow.com/questions/52889490/…
stackoverflow.com/questions/52922240/…
改变 toArray() 到 toJson() 方法
尝试返回 response()->json($spent_time->fresh()->toArray());
