Property.php

<?php
namespace App;

use Illuminate\Database\Eloquent\Model;

class Property extends Model
{
    protected $guarded = ['id'];

    public function category()
    {

    }
}

CategoryController.php

<?php

use App\Http\Controllers\Controller;
use App\Property;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Redirect;

class CategoryController extends …
