with problems, when saving create new data then an error "Trying to get property of non-object"

but there is one data that can save when creating new data, but cannot yet calculate the data, and while the other categories cannot be like that, instead the error

what should be corrected from this problem?

        $new_spent_time['percentage'] = (int)$new_spent_time->percentage  + $spent_time->daily_percentage;

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

Answer 2

在您的 SpentTime 模型中，您可以创建 accessors 这些函数可在此处用于查询所有相关记录的一天总和：

public function getDailySpentTimeAttribute()
{
    return self::where('task_category_id', $this->task_category_id)
        ->get()
        ->sum('daily_spent_time');
}

public function getDailyPercentageAttribute()
{
    return self::where('task_category_id', $this->task_category_id)
        ->get()
        ->sum('daily_percentage');
}

在这里，我们创建两个accessors，一个用于获取每日花费时间，另一个用于获取每日百分比，用于所有基于相关task_category.

的记录

可以调用如下：

$dailySpentTime = SpentTime::find($id)->dailySpentTime;

// or within your blade template

{{ $spentTime->dailySpentTime }}

更新

在您的控制器中，由于您不再需要运行在保存时进行任何计算，您可以执行以下操作：

public function store(Request $request)
{      
    $spent_time = SpentTime::findOrCreate($request->get('plan_id'), [
        'task_category' => $request->get('task_category'),
        'reason'        => $request->get('reason'),
    ]);

    return redirect()->route('real.index', compact('spent_time'));
}

确保删除当前覆盖 laravel 版本的自定义 findOrCreate() 方法。

希望这对您有所帮助。

Answer 3

the data is there, when dd($spent_time);

dd($spent_time);
