SQLSTATE[42S22]: Column not found: 1054 Unknown column 'name' in 'where clause' (SQL: select * from roles where name = user limit 1)
this is my user model:
<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email','user_type', 'password'
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

this is my role model:
<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Roles extends Model
{
    //

     protected $fillable = [
        'libelle'
    ];
}

this is my user Controller:
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;

use Auth;
use App\User;

class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */

public function __construct()
{
    $this->middleware('auth');
}

    public function getRowAttributes()
    {
        return view('manage_users.index');
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */

    //ouvrir le formulaire
    public function create()
    {
        return view('manage_users/create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */

    //save data 
    public function store(Request $request)
    {
        $this->validate($request,[

              'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255',
            'user_type' => 'required',
            'password' => 'required|string|min:6|confirmed'
        ]);

        $user=new User([
              'name' => $request->get('name'),
             'email' => $request->get('email'),
             'user_type'  => $request->get('user_type'),
             'password' => bcrypt($request->get('password'))

        ]);
        $user->save();
        return redirect('manage_users/index')->with('success','Data Added');

    }

    /**

this is my role Controller:
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Roles;

class RolesController extends Controller
{
    //
public function __construct()
{
    $this->middleware('auth');
}
      public function index()
    {
        $roles = Roles::all();

        return view('manage_users.create', ['roles' => $roles]);
    }

}

this is my route in web.php

Route::get('manage_users/index', 'UserController@getRowAttributes')->name('index');

//Route::get('manage_users/column_search', 'UserController@getColumnSearch')->name('column_search');

//Route::get('manage_users/index','UserController@index');

//Route::resource('manage_users','UserController');

Route::get('manage_users/create','UserController@create');
Route::get('manage_users/create','RolesController@index');
Route::post('manage_users/create','UserController@store');
//Route::get('manage_users/index','UserController@index');

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'name' in 'where clause' (SQL: select * from roles where name = user limit 1)

A:

As I can see below code on User model
protected $fillable = [
    'name', 'email','user_type', 'password'
];

It seems you've added the name column in users table, 
you should add name column on roles table as well by following below steps
STEPS TO FOLLOW:
1.Run the command : 
php artisan make:migration alter_table_roles_add_name_column
//This will create a new migration file
2.Add the below methods on the new migration file
public function up()
{
    Schema::table('roles', function (Blueprint $table) {
        $table->string('name')
        ->after('id'); //optional
    });
}

public function down()
{
    Schema::table('roles', function (Blueprint $table) {
        $table->dropColumn('name');
    });
}

3.Finally run the command : php artisan migrate
I hope this will solve your problem
