python - 使用 cleaned_data 时为 "TypeError: string indices must be integers"

Question

错误发生在这里:

if request.method == 'POST':
        form = RegisterForm(request.POST)
        if form.is_valid():
            clean = form.cleaned_data

            username = clean['username']
            email = clean['email']
            password = clean['password']
            new_user = User.objects.create_user(username, email, password)
            new_user.save()
            new_account = Account(user=new_user, email=email)
            new_account.save()

在 username = clean['username'] 行。我已经能够在其他地方成功地使用这条确切的线而没有问题。为什么现在是个问题？

您可能从表单的 clean() 方法返回了错误的内容 - 您应该返回完整的 self.cleaned_data 字典。
