Call to a member function get() on null for a function in a model - laravel-5

Question

I am trying to have a button of an employee show the text “Already booked” if the variable
count($bookingRequests) returns something and if nothing then show “Book Me’
I get the error above.
I have the following models and their relationships:
User.php and Bookings.php
User:
public function bookings() {
return $this->hasMany('App\Models\Bookings');
}
public function BookingRequest()
{
$this->bookings()->where('booking_status','=','confirmed')->get();
}
Bookings:
public function user(){
return $this->belongsTo('App\Models\User');
}
The view mentioned above is Employeeblock.blade.php:
<div class="row no-gutters mb-5 mb-lg-0" style="padding:10px">
#if(count($bookingRequests))
<a href="#" class="btn btn-primary" data-
toggle="modal" data-target=“#bookingModal">Already Booked</a>
#else
<a href="#" class="btn btn-primary" data-
toggle="modal" data-target="#bookingModal">Book Me</a>
#endif
</div>
Which has data passed onto it by a controller SearchController:
In the following way:
<?php
namespace App\Http\Controllers;
use DB;
use Auth;
use App\Models\Employee;
use App\Models\User;
use App\Models\Bookings;
use Illuminate\Http\Request;
use GuzzleHttp\Client;
use Session;
.
.
.
$bookingRequests=Auth::user()->BookingRequest()->get();
return view(‘search.results’)
->with('bookingRequests',$bookingRequests)
results.blade.php above has the following html:
<div class="panel panel-default">
<div class="panel-heading"><h3></h3></div>
<div class="panel-body">
<div class="row">
<div class="col-lg-12">
#foreach($Employees as $Employee)
#include('user/partials/employeeblock')
#endforeach
</div>
</div>
</div>
</div>
</div>

Answer 1

Replace:
$bookingRequests=Auth::user()->BookingRequest()->get();
with
$bookingRequests=Auth::user()->BookingRequest();
Because your BookingRequest() method already use ->get() method to obtain data from db.
