在laravel中传递参数

i have an index pages with a link_to:

<h1> User:</h1>
        @foreach ($user as $user)

            {{link_to("/users/{$user->username}",$user->username)}}
        @endforeach

then i have a route:

Route::get('/users/{{$username}}', function($username){

        return View::make('show')->with('username',$username);

});

Now, if i understand clear, i am passing username as parameter to function, and username is my url, now if i pass parameter to my show view,

<body>
    <div>       

        <h1> User:</h1>
            {{$username}}
    </div>
</body>
</html>

I should be able to see it in my page. Where i am wrong? I can't take a parameter from the url when i use get? Why i need to do:

Route::get('/users/{{$username}}', function($username){
$user=User::whereUsername($username)->fist();

        return View::make('show')->with('username',$user);
});

    Your route is wrong, this is the correct one:

    Route::get('/users/{username}', function($username){

    $user=User::whereUsername($username)->fist();

    return View::make('show')->with('user',$user);

});

    It's just

    /users/{username}

    and not 

    /users/{{$username}}

    Also, you view will receive an user object, so you have to:

     <div>       
     <h1> User:</h1>
         {{$user->username}}
 </div>

    EDIT

    In Laravel there are 2 kind {}:

    1) In views you have to use {{}} or {{{}}} (escaped version). Inside them you put PHP code:

    {{$variable}}

{{ isset($variable) ? $variable : 'default value' }}

    2) In routes, you just use {} and inside it it's not PHP, just a route parameter name, without $:

    /user/{name}

/user/{id?} (in this case id is optional, might or might not be send)
