无法保存新数据，并且无法将Array转换为字符串?

问题描述

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的形式输入到表中.

Controller in laravel

in function store, can't save data and can't calculation data by category when create new data, data should be calculated and entered into the table as pict.

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'));
}

推荐答案

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);

这里您将$spent_time->task_category(数组)分配给'task_category'(字符串字段).

Here you assigning $spent_time->task_category (an array) to 'task_category' (a string field).

更改上述变量的值将解决您的问题.

Change value of above variable it will fix your issue.
