Get top 10 frequent table entites which were max two days old?

Question

This is my mySql table "listazelja": http://prntscr.com/duj2tf

i want to get what is mentioned in title with this code in my controller:

<?php

namespace App\Http\Controllers;

use App\ListaZelja;
use Carbon\Carbon;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

class GlazbeniController extends Controller
{
    public function listazelja(){

        $sada = Carbon::now();

        $listaZelja = DB::table('listazelja')->orderBy('zapis_count','desc')->select(DB::raw('count(*) as zapis_count'),'zapis_id')
            ->groupBy('zapis_id')
            ->having($sada->diffInHours(Carbon::createFromFormat('Y-m-d H-m-s', 'created_at')) <= 48)
            ->take(10)->get();

        return view('pregledajlistuzelja',compact('listaZelja'));
    }
}

This is error I am getting:

InvalidArgumentException in Carbon.php line 425: A four digit year could not be found Data missing

I know that problem is with this line of code: ->having($sada->diffInHours(Carbon::createFromFormat('Y-m-d H-m-s', 'created_at')) <= 48)

so what should I do to make it work.

P.S. created_at in mySql is of type: timestamp

Answer 1

I think your query like:

$twoDaysOldDate = date("Y-m-d",strtotime('now -48 hours'));
$listaZelja = DB::table('listazelja')
           ->orderBy('zapis_count','desc')
           ->select(DB::raw('count(*) as zapis_count'),'zapis_id')
           ->groupBy('zapis_id')
           ->whereDate('created_at', '<=', $twoDaysOldDate)
           ->take(10)
           ->get();

Hope this work for you!
