出于分析目的，我正在分析注册视图。
我想了解SignUp View是否可以改进。现在可以使用，但是可以改进吗？
例如，如果我使用：
username = user.cleaned_data.get('username')
代替：
username = user_form.cleaned_data.get('username')
我得到这个错误：
'User' object has no attribute 'cleaned_data'
为什么？
注册视图：
@transaction.atomic
def signupView(request):

department_list = set()
province_list = set()

奖金：

之前
if user_form.is_valid() and profile_form.is_valid():
但也要紧随其后。正确吗？

答案 0 :(得分：1)
“用户”是用户模型的实例，它没有cleaned_data。只有表单具有该属性。
