有人能帮助解释以下错误以及它与下面代码的关系吗？
我所要做的就是保存一张表格。
错误

# Don't show user drop down.
exclude = ('user',)
def clean(self):
cleaned_data = super(RegistrationForm, self).clean()
try:

passwordConfirm = cleaned_data['passwordConfirm']
if password != passwordConfirm:
raise forms.ValidationError("Password does not match, try again.")
return cleaned_data
except:
raise forms.ValidationError("Password does not match, try again.")
username = cleaned_data['username']
try: User.objects.get(username=username)
except User.DoesNotExist:
return username
raise forms.ValidationError("Username already taken, try another.")
更新的def-clean
def clean(self):
try:
cleaned_data = super(RegistrationForm, self).clean()
password = cleaned_data.get("password")
passwordConfirm = cleaned_data.get('passwordConfirm')
if password != passwordConfirm:
raise forms.ValidationError("Password does not match, try again.")
return cleaned_data
except:
raise forms.ValidationError("Error")
我希望你已经发布了完整的回溯，那么解决你的问题会容易得多。
然而，我想这是因为你在clean函数中随机返回了一些东西。在某一点上有return cleaned_data，但在那之后有return username。您确实需要从该函数返回cleaned_data，但您应该在末尾执行操作，否则您将永远无法真正到达第二个验证器。
在视图.py的第17行中，它说：
form = RegistrationForm
相反，它应该是
form = RegistrationForm()
你的错误来源可能有所不同，但我只是想提一下
