Can't insert data into Mongodb in Laravel - mongodb

Question

Let me explain all the step that I followed. I am using LAMP.
First of all I installed Laravel , MongoDB and jenssegers/laravel-mongodb pakage. For this I followed this link.
After that I create database, table and insert data using terminal with all success.
Next step is to integrate mongodb with laravel so I add MongoDB connection detail in app/config/database.php file.
'mongodb' => [
'driver' => 'mongodb',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', 27017),
'database' => env('DB_DATABASE', 'usedgoodstore'),
],
'default' => env('DB_CONNECTION', 'mongodb'),
Up to this point all work fine.
Next I create route, view, controller, model file and insert code.
routes/web.php
Route::post('/index', 'UserController#index');
welcome.blade.php
<form action="{{ url('/index') }}" method="post">
<input name="_token" type="hidden" value="{{ csrf_token() }}"/>
First name:<br>
<input type="text" name="firstname">
<br>
Last name:<br>
<input type="text" name="lastname">
<br><br>
<input type="submit" value="Submit">
</form>
UserController.php
<?php
namespace App\Http\Controllers;
use App\Model\User;
use Illuminate\Http\Request;
class UserController extends Controller{
protected $user;
public function __construct(User $user){
$this->user = $user;
}
public function Index(Request $request){
$data = array('firstname' => $request['firstname'], 'lastname' => $request['lastname']);
$user = $this->user->PostUser($data);
return response()->json($user,200);
}
}
User.php (model file)
<?php
namespace App\Model;
use Jenssegers\Mongodb\Eloquent\Model as Moloquent;
use DB; // if I use and not use this statement and then getting different errors
class User extends Moloquent {
protected $connection = 'mongodb';
protected $collection = 'user';
public function PostUser($data){
$insertData = DB::collection('user')->insert($data); // I'm getting error on this line.
if($insertData){
return true;
}
}
}
Error I'm getting is :
FatalThrowableError in User.php line 25:
Class 'App\Model\DB' not found
If I add use db in User.php (model file) I'm getting below error.
FatalThrowableError in DatabaseManager.php line 317:
Call to undefined method Illuminate\Database\MySqlConnection::collection()
What have I missed?

First open app/config/database.php file and make your mongodb default database.
'default' => 'mongodb',
and if you don't want mongodb as a default database connection then you can do following thing.
public function PostUser($data){
$insertData = DB::connection('mongodb')->collection('user')->insert($data); // I'm getting error on this line.
if($insertData){
return true;
}
