“试图获取非对象的属性”

模型

在创建新数据并要保存时，如上所述发生错误

public static function findOrCreate($plan_id, $data)
{
    $fromDate = Carbon::now()->subDay()->startOfWeek();
    $nowDate = Carbon::now()->today();

    $spent_time = static::where('plan_id', $plan_id)->first();

    if (is_null($spent_time)) {
        return static::create($data);
    }else{
        $new_spent_time = SpentTime::find($plan_id);
        $task_category = $new_spent_time->task_category;

        $new_spent_time->task_category = (['{task_category}' => $task_category, 
                                        '{daily_spent_time}' => $new_spent_time->daily_spent_time,
                                        '{daily_percentage}' => $new_spent_time->daily_percentage,
                                        '{spent_time}' => $new_spent_time->spent_time,
                                        '{percentage}' => $new_spent_time->percentage, $new_spent_time->task_category]);

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

        return $spent_time->update($data);
    }

Answer 1

"Trying to get property of non-object"表示该属性不存在

将您的find更改为findOrFail

$new_spent_time = SpentTime::findOrFail($plan_id);

这样，laravel在数据库中找不到记录时将返回错误。

另一种方法是检查查询是否成功：

$new_spent_time = SpentTime::find($plan_id);
if($new_spent_time){

    $task_category = $new_spent_time->task_category;

    $new_spent_time->task_category = (['{task_category}' => $task_category, 
                                    '{daily_spent_time}' => $new_spent_time->daily_spent_time,
                                    '{daily_percentage}' => $new_spent_time->daily_percentage,
                                    '{spent_time}' => $new_spent_time->spent_time,
                                    '{percentage}' => $new_spent_time->percentage, $new_spent_time->task_category]);

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

    return $spent_time->update($data);
}else{
    return 'no result found';
}

应该在存储创建的数据时转到表格并计算数据量
