Laravel - Authentication trait error exception - php

Question

I am doing an ajax login in my Laravel application. It worked fine on my local environment, but I moved the site to Production, on login I see this exception
ErrorException in User.php line 29: Illuminate\Foundation\Auth\User
and Illuminate\Auth\Authenticatable define the same property
($rememberTokenName) in the composition of App\User. This might be
incompatible, to improve maintainability consider using accessor
methods in traits instead. Class was composed
My User model is as
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable, \Illuminate\Auth\Authenticatable;
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name', 'email', 'password', 'first_name', 'last_name', 'hospital_id', 'census_id', 'employee_id'
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
}

Illuminate\Foundation\Auth\User already uses use Illuminate\Contracts\Auth\Authenticatable, so you basically applying the trait twice which causes that error.
Here's the code to Illuminate\Foundation\Auth\User.php
<?php
namespace Illuminate\Foundation\Auth;
use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Foundation\Auth\Access\Authorizable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;
class User extends Model implements
AuthenticatableContract,
AuthorizableContract,
CanResetPasswordContract
{
use Authenticatable, Authorizable, CanResetPassword;
}
Also a side suggestion rename your alias bit as Authenticable maybe to something more clear like AuthUser / BaseUser so it's clear you are extending a User class.
