如何將Django表單方法設置爲不500時調試錯誤提高表單錯誤？

Question

我有以下代碼爲我登錄：

class LoginForm(forms.Form): 
    email = forms.EmailField(max_length = 254, min_length = 6) 
    password = forms.CharField(min_length = 8, widget = forms.PasswordInput()) 

    def Login(self): 
     email = self.cleaned_data.get('email') 
     password = self.cleaned_data.get('password') 
     user = authenticate(email = email, password = password) 

     if (user is None) or (user is not None and user.is_active is False): 
      raise forms.ValidationError('Login is incorrect.') 

     return user 

然而，當我有調試設置爲false，在我的網站，只要登錄不正確，我得到一個500錯誤，而不是顯示ValidationError形式。我稱它爲：

if form.is_valid(): 
    user = form.Login() 

這是在視圖方法。我在這裏錯過了什麼？如果調試設置爲false，我該如何正確調用這個表單錯誤，使其不到500？

呼叫這樣

def clean(self): 
    password = self.cleaned_data.get('password') 
    email = self.cleaned_data.get('email') 
    user = authenticate(email = email, password = password) 
    if (user is None) or (user is not None and user.is_active is False): 
     raise forms.ValidationError('Login is incorrect.') 
    return self.cleaned_data 

def login(self,request): 
    user = authenticate(email = self.cleaned_data.get('email'),password = self.cleaned_data.get('password')) 
    user = authenticate(username=username, password=password) 
    return user
