別の表示機能にリダイレクト

Question

ユーザーのログイン時に、URLに「/ login /」を付けるのではなく、単にインデックスにリダイレクトしたいと思います。

ログインとインデックス用に2つのビュー機能があります。

インデックスビュー

def index(request): 

    context = { 

    } 
    return render(request, 'index.html', context) 

ログインビュー

def login(request): 

    username = request.POST.get('username', '') 
    password = request.POST.get('password', '') 

    user = auth.authenticate(username=username, password=password) 

    if user is not None: 
     auth.login(request, user) 
    else: 
     print('Wrong user') 

    return redirect('index') #<------ Something like that(?) 

URLパターン

urlpatterns = [ 
      url(r'^$', views.index, name='index'), 

      url(r'^login/$', views.login, name='login'),  
] 

コンソールエラー：

# views.py 
def login(...):

    return redirect('home') 

と：あなたの答えのための

# urls.py 
urlpatterns = [ 
    url(r'^$', 'views.index', name='home'), 
    # ... 
]
