我收到以下行的錯誤：username = login_form.cleaned_data('username')，因為在某個地方它似乎是一個字典，但我無法理解為什么。誰能告訴我，問題是什么？views.pydef index(request): return render(request, 'web/base.html')def register_view(request): register_form = UserCreationForm() if request.method == "POST": register_form = UserCreationForm(request.POST) if register_form.is_valid(): register_form.save() username = register_form.cleaned_data("username") password = register_form.cleaned_data("password1") user = authenticate(request, username=username, password=password) if user: login(request, user) return render(request, 'web/register.html', {'register_form': register_form})def login_view(request): login_form = AuthenticationForm() if request.method == 'POST': login_form = AuthenticationForm(data=request.POST) if login_form.is_valid(): username = login_form.cleaned_data('username') password = login_form.cleaned_data('password') user = authenticate(request, username=username, password=password) if user: login(request, user) return render(request, 'web/login.html', {'login_form': login_form})def logout_view(request): logout(request) return redirect(reverse('web:index'))

Form.cleaned_data從設(shè)計上來說，它確實是一本字典。要獲取字典中鍵的值，請使用[ ]，例如
username?=?register_form.cleaned_data["username"]

從字典中獲取值，例如：
username = login_form.cleaned_data['username'] password = login_form.cleaned_data['password']
您無法使用 () 而是使用 [] 來獲取 DICTIONARIES 中鍵的值。

login_form.cleaned_data是一本字典，所以username = login_form.cleaned_data('username')沒有意義，你應(yīng)該使用：
username = login_form.cleaned_data['username'] password = login_form.cleaned_data['password']
因此，元素也會發(fā)生同樣的情況password。
