I am developing a system that fetches data from two databases. I want to do a login function but direct the function to the other database(mysql2 in config/database) to the other database and not default database(mysql). This is my config/database.php

  # Knust primary database connection
 'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => 'hofsa_knust',
        'username'  => 'root',
        'password'  => '',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],

         # Legon primary database connection
         'mysql2' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => 'hofsa_legon',
        'username'  => 'root',
        'password'  => '',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],

This is my controller

 <?php

 namespace App\Http\Controllers;
 use Illuminate\Support\Facades\Validator;
 use Illuminate\Support\Facades\Hash;
 use Illuminate\Support\Facades\Auth;
 use App\Http\Requests;
 use App\Http\Controllers\Controller;
 use App\Http\Requests\CreateUserRequest;
 use UxWeb\SweetAlert;
 use App\LegonUser;
 use Request;
 use Alert;
 use DB;
 class LegonUserController extends Controller
    {
  public function LegonSignin() {
   $input = Request::all();
  $user_data = [
  'username' => $input['username'],
  'password' => $input['password']
];

//$database = LegonUser::on('mysql2')->select('*')->where($user_data ,'=',         $user_data)->get();
$legonModel = new LegonUser;
$legonDB = $legonModel->setConnection('mysql2');

if ($legonDB) {
  if (Auth::attempt($user_data)) {
    //Alert::success('You Have Successfully Signed In', 'Great !');
    alert()->success('You Have Successfully Signed In', 'Great !')->autoclose(2500);
    return redirect('/');
  } else {
    return redirect()->back()->withErrors($user_data);
  }
}

} }

This is my Eloquent Model

 <?php

namespace App;

use Illuminate\Auth\Authenticatable; use Illuminate\Database\Eloquent\Model; use Illuminate\Auth\Passwords\CanResetPassword; use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract; use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

class LegonUser extends Model implements AuthenticatableContract, CanResetPasswordContract { use Authenticatable, CanResetPassword;

/**
 * The database name used by the model.
 *
 * @var string
 */
protected $connection = 'mysql2';
/**
 * The database table used by the model.
 *
 * @var string
 */
protected $table = 'users';

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = ['firstname', 'lastname', 'username', 'nickname', 'password'];

/**
 * The attributes excluded from the model's JSON form.
 *
 * @var array
 */
protected $hidden = ['password', 'remember_token'];

} After all these, it still goes to the default database and not the custom one(mysql2).
