How to catch QueryException error when using Laravel Auth - laravel

Question

I tested my app to disallow duplication of emails. It works, however I can't catch the error or it doesn't display the request error in the form page whenever it found duplication.
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry
'admin#DOMAIN.com' for key 'admins_email_unique'
I already tried overriding the RegisterController, but still can't find where the error is being fetch first.
protected function create(array $data)
{
try{
return Admin::create([
'role_id' => $data['role_id'],
'username' => $data['username'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
}
catch(Illuminate\Database\QueryException $e)
{
echo($e);
}
}
My current RegisterController
<?php
namespace App\Http\Controllers\AdminAuth;
use App\Admin;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Auth;
use Illuminate\Http\Request;
use App\Traits\RoleTrait;
class RegisterController extends Controller
{
/*
|--------------------------------------------------------------------------
| Register Controller
|--------------------------------------------------------------------------
|
| This controller handles the registration of new users as well as their
| validation and creation. By default this controller uses a trait to
| provide this functionality without requiring any additional code.
|
*/
use RegistersUsers;
use RoleTrait;
/**
* Where to redirect users after login / registration.
*
* #var string
*/
protected $redirectTo = '/admin/home';
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('admin.guest');
}
/**
* Create a new user instance after a valid registration.
*
* #param array $data
* #return \App\User
*/
protected function create(array $data)
{
return Admin::create([
'role_id' => $data['role_id'],
'username' => $data['username'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
}
/**
* Get a validator for an incoming registration request.
*
* #param array $data
* #return \Illuminate\Contracts\Validation\Validator
*/
protected function validator(array $data)
{
return Validator::make($data, [
'role_id' => 'required|string|max:4',
'username' => 'required|string|unique:users|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
]);
}
/**
* Show the application registration form.
*
* #return \Illuminate\Http\Response
*/
public function showRegistrationForm()
{
$mgaAdminRoleNames = $this->getAdminRoleNames();
return view('admin.auth.register')->with('adminRoleNames',$mgaAdminRoleNames);
}
/**
* Get the guard to be used during registration.
*
* #return \Illuminate\Contracts\Auth\StatefulGuard
*/
protected function guard()
{
return Auth::guard('admin');
}
I already put in admin\auth\register.blade.php
#if ($errors->has('email'))
<span class="invalidMessage">
<strong>{{ $errors->first('email') }}</strong>
</span>
#endif
The expected solution either of this two:
1) Display error in the form page like this:
Image Here
2) Or catch the QueryException and echo the error directly

Answer 1

use validations for duplicate entry i hope this link will be helpful laravel recommended link

Answer 2

I found an answer while I'm checking the validator. So if anyone encounter this problem. Here's the solution:
protected function validator(array $data)
{
return Validator::make($data, [
'role_id' => 'required|string|max:4',
'username' => 'required|string|unique:admins|max:255',
'email' => 'required|string|email|max:255|unique:admins',
'password' => 'required|string|min:6|confirmed',
]);
}
Notice the "unique" attribute. I change it from "users" to "admins".
I think the word "admins" came from config\auth.php directory where you set your guards and providers stuff.
