Rent available cars from rentals table

I have my table with rentals

id| user_id| car_id | starting_date | ending_date

and here is cars table
id | name

I don’t know how to habndle the situation.. I have N cars, and I want to return only available cars for specific dates.

For example I want to rent a car on this period:
20.02.2018 – 23.02.2018

But I don’t know how to check every case to see if a car is available in that period using Laravel.

Method 1

Use the whereDoesntHave() method. I assume you already have rentals relationship defined:

$date1 = Carbon::parse('20.02.2018')->startOfDay();
$date2 = Carbon::parse('23.02.2018')->endOfDay();
$available = Car::whereDoesntHave('rentals', function($q) use($date1, $date2) {
    $q->whereBetween('starting_date', [$date1, $date2])
      ->orWhereBetween('ending_date', [$date1, $date2])
      ->orWhere(function($q) use($date1, $date2) {
          $q->where('starting_date', '<', $date1)
            ->where('ending_date', '>', $date2);

If you don’t have the relationship, define it in the Car model:
public function rentals()
    return $this->hasMany(Rental::class);
