提问by BARNOWL
Just to preface this, i have went through most of the answers that are aligned to my question, pretty much i have a undefined variablefor user.
只是作为序言，我已经浏览了与我的问题一致的大多数答案，几乎我有一个未定义的用户变量。
I want to be able to display the registered user on the dashboard, i used this code before and it worked but not for this application.
我希望能够在仪表板上显示注册用户，我之前使用过此代码并且它有效但不适用于此应用程序。
Undefined variable: user (View: /Applications/MAMP/htdocs/eli/resources/views/dashboard.blade.php)
Here is my code,
这是我的代码，
UserController.php
用户控制器.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\User;
use App\Http\Requests;
class UserController extends Controller
{
public function getWelcome()
{
return view('welcome');
}
public function getDashboard()
{
$users = User::all();
return view('dashboard', compact('users'));
}
public function userSignUp(Request $request)
{
$this->validate($request, [
'email' => 'required|email|unique:users',
'first_name' => 'required|max:120',
'password' => 'required|min:4'
]);
$email = $request['email'];
$first_name = $request['first_name'];
$password = bcrypt($request['password']);
$user = new User();
$user->email = $email;
$user->first_name = $first_name;
$user->password = $password;
$user->save();
return redirect()->route('dashboard');
}
public function postSignin(Request $request)
{
$remember = $request->input('remember_me');
if(Auth::attempt(['email'=> $request['email'], 'password' => $request['password']], $remember )){
return redirect()->route('dashboard');
}
return redirect()->back();
}
}

You're passing $userscollection to the view, so you need to iterate over it if you want to display names of all users:
您正在将$users集合传递给视图，因此如果要显示所有用户的名称，则需要对其进行迭代：
@foreach ($users as $user)
{{ $user->username }}
@endforeach
If you want to display name of authenticated user, just do this instead:
如果要显示经过身份验证的用户的名称，只需执行以下操作：
{{ auth()->user()->username }}
