how to calculate data by category when creating new data with the same category

Question

Model

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

In your SpentTime model, you are able to create accessors which are functions that can be used here to query the sum a day of all relating records:

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');
}

Here, we create two accessors, one to get the daily spent time and another to get the daily percentage, for all records based on relating task_category.

There can be called using the following:

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

// or within your blade template

{{ $spentTime->dailySpentTime }}

Update

Within your controller, as you no longer have to run any calculations upon saving, you can do the following:

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'));
}

Make sure to delete your custom findOrCreate() method which is currently overriding the laravel version.

Hopefully this helps.
