无法保存新数据，并且无法将Array转换为字符串？

Question

laravel中的模型

  

“数组到字符串的转换（SQL：更新spent_times设置updated_at = 2018-10-18 06:02:29，spent_time = 12，percentage = 60.00 ，task_category =测试id = 7）◀“

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

    $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->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 = SpentTime::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;
        $new_spent_time->save();
        return $spent_time->update($data);
    }
}

laravel中的控制器

在函数存储中，创建新数据时无法按类别保存数据，也不能按类别计算数据，应计算数据并以pict的形式输入表中。

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

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

Answer 1

您在下面的行中有错误

$new_spent_time->percentage = SpentTime::where('task_category', $spent_time->task_category)->sum('daily_percentage', $new_spent_time->daily_percentage, $fromDate);

在这里，您将$spent_time->task_category（数组）分配给'task_category'（字符串字段）。

更改上述变量的值将解决您的问题。

型号

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

    $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 = $new_spent_time::where('task_category',$spent_time->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);
    }
}

控制器

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