How to get login with different database table column name in Laravel 5.2?

I searched a lot how to customize Laravel 5.2 authorisation form and this is what is working for me 100%. Here is from bottom to top solution.

This solution is originally from here: https://laracasts.com/discuss/channels/laravel/replacing-the-laravel-authentication-with-a-custom-authentication

but i had to make couple changes to make it work.

My web app is for the DJs so my custom column names are with 'dj_', for example name is dj_name

config/auth.php

// change this
'driver' => 'eloquent',
// to this
'driver' => 'custom',

in config/app.php add your custom provider to the list ...

'providers' => [
    ...
    // add this on bottom of other providers
    App\Providers\CustomAuthProvider::class,
    ...
],

Create CustomAuthProvider.php inside folder app\Providers

namespace App\Providers;

use Illuminate\Support\Facades\Auth;

use App\Providers\CustomUserProvider;
use Illuminate\Support\ServiceProvider;

class CustomAuthProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        Auth::provider('custom', function($app, array $config) {
       // Return an instance of             Illuminate\Contracts\Auth\UserProvider...
        return new CustomUserProvider($app['custom.connection']);
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

Create CustomUserProvider.php also inside folder app\Providers

<?php

namespace App\Providers;
use App\User; use Carbon\Carbon;
use Illuminate\Auth\GenericUser;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Contracts\Auth\UserProvider;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Log;

class CustomUserProvider implements UserProvider {

/**
 * Retrieve a user by their unique identifier.
 *
 * @param  mixed $identifier
 * @return \Illuminate\Contracts\Auth\Authenticatable|null
 */
public function retrieveById($identifier)
{
    // TODO: Implement retrieveById() method.


    $qry = User::where('dj_id','=',$identifier);

    if($qry->count() >0)
    {
        $user = $qry->select('dj_id', 'dj_name', 'first_name', 'last_name', 'email', 'password')->first();

        $attributes = array(
            'id' => $user->dj_id,
            'dj_name' => $user->dj_name,
            'password' => $user->password,
            'email' => $user->email,
            'name' => $user->first_name . ' ' . $user->last_name,
        );

        return $user;
    }
    return null;
}

/**
 * Retrieve a user by by their unique identifier and "remember me" token.
 *
 * @param  mixed $identifier
 * @param  string $token
 * @return \Illuminate\Contracts\Auth\Authenticatable|null
 */
public function retrieveByToken($identifier, $token)
{
    // TODO: Implement retrieveByToken() method.
    $qry = User::where('dj_id','=',$identifier)->where('remember_token','=',$token);

    if($qry->count() >0)
    {
        $user = $qry->select('dj_id', 'dj_name', 'first_name', 'last_name', 'email', 'password')->first();

        $attributes = array(
            'id' => $user->dj_id,
            'dj_name' => $user->dj_name,
            'password' => $user->password,
            'email' => $user->email,
            'name' => $user->first_name . ' ' . $user->last_name,
        );

        return $user;
    }
    return null;



}

/**
 * Update the "remember me" token for the given user in storage.
 *
 * @param  \Illuminate\Contracts\Auth\Authenticatable $user
 * @param  string $token
 * @return void
 */
public function updateRememberToken(Authenticatable $user, $token)
{
    // TODO: Implement updateRememberToken() method.
    $user->setRememberToken($token);

    $user->save();

}

/**
 * Retrieve a user by the given credentials.
 *
 * @param  array $credentials
 * @return \Illuminate\Contracts\Auth\Authenticatable|null
 */
public function retrieveByCredentials(array $credentials)
{

    // TODO: Implement retrieveByCredentials() method.
    $qry = User::where('email','=',$credentials['email']);

    if($qry->count() > 0)
    {
        $user = $qry->select('dj_id','dj_name','email','password')->first();


        return $user;
    }

    return null;


}

/**
 * Validate a user against the given credentials.
 *
 * @param  \Illuminate\Contracts\Auth\Authenticatable $user
 * @param  array $credentials
 * @return bool
 */
public function validateCredentials(Authenticatable $user, array $credentials)
{
    // TODO: Implement validateCredentials() method.
    // we'll assume if a user was retrieved, it's good

    // DIFFERENT THAN ORIGINAL ANSWER
    if($user->email == $credentials['email'] && Hash::check($credentials['password'], $user->getAuthPassword()))//$user->getAuthPassword() == md5($credentials['password'].\Config::get('constants.SALT')))
    {


        //$user->last_login_time = Carbon::now();
        $user->save();

        return true;
    }
    return false;


}
}

in App/Http/Controllers/Auth/AuthController.php change all 'name' to 'dj_name' and add your custom fields if you have them...you can also change 'email' to your email column name

In Illuminate\Foundation\Auth\User.php add

protected $table = 'djs';
protected $primaryKey  = 'dj_id';

In App/User.php change 'name' to 'dj_name' and add your custom fields. For changing 'password' column to your custom column name add
```
public function getAuthPassword(){
    return $this->custom_password_column_name;
}
```
Now backend is all done, so you only have to change layouts login.blade.php, register.blade.php, app.blade.php...here you only have to change 'name' to 'dj_name', email, or your custom fields... !!! password field NEEDS to stay named password !!!

Also, to make unique email validation change AuthController.php

'custom_email_field' => 'required|email|max:255|unique:users',
to
'custom_email_field' => 'required|email|max:255|unique:custom_table_name',

Also, if you want to make custom created_at an updated_at fields change global variables in Illuminate\Database\Eloquent\Model.php

const CREATED_AT = 'dj_created_at';
const UPDATED_AT = 'dj_updated_at';

This is easy simply use the desired column names in Auth::attempt()/method like so:

if (Auth::attempt(['st_username' =>$username,'st_password' => $password])) { 
    // Authentication passed... 
    return redirect()>intended('dashboard'); 
}

Updated: If you also wish to change default authentication table which is users by default or change the model name or path App\User by default, you can find these settings in config\auth.php

/*
|--------------------------------------------------------------------------
| Authentication Table
|--------------------------------------------------------------------------
|
| When using the "Database" authentication driver, we need to know which
| table should be used to retrieve your users. We have chosen a basic
| default value but you may easily change it to any table you like.
|
*/

//'table' => 'users', 
'table' => 'new_tables_for_authentication',



/*
|--------------------------------------------------------------------------
| Authentication Model
|--------------------------------------------------------------------------
|
| When using the "Eloquent" authentication driver, we need to know which
| Eloquent model should be used to retrieve your users. Of course, it
| is often just the "User" model but you may use whatever you like.
|
*/

//'model' => App\User::class,
'model' => App\Models\User::class,

A custom Auth::attempt() doesn't work for me by changing the model in auth.php like this:

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\Person::class,
    ],
],

If I try to authenticate a Person via custom column names in Auth::attempt:

if (Auth::attempt(['persUsername' => $request->user, 'persPassword' => $request->pass])) {
    return redirect()->intended('/');
}

I get the same error:

ErrorException in EloquentUserProvider.php line 112: Undefined index: password

But I can authenticate a Person like this:

$person = Person
    ::where('persUsername', $request->user)
    ->where('persPassword', $request->pass)
    ->first();

if (! is_null($person)) {
    if ($person->persUsername === $request->user && $person->persPassword === $request->pass) {
        Auth::login($person, false);
        return redirect()->intended('/');
    }
}

But that's not the way it should be, I guess.

In the mentioned File (EloquentUserProvider.php), I see 'password' is hardcoded.

public function retrieveByCredentials(array $credentials)
{
    $query = $this->createModel()->newQuery();

    foreach ($credentials as $key => $value) {
        if (! Str::contains($key, 'password')) {
            $query->where($key, $value);
        }
    }

    return $query->first();
}

public function validateCredentials(UserContract $user, array $credentials)
{
    $plain = $credentials['password'];

    return $this->hasher->check($plain, $user->getAuthPassword());
}

So there is actually no way to use a custom column name for passwords the easy way?
