当请求空白的RegisterForm时，我得到一个KeyError。我相信当我点击网站上的链接时，我向register方法提交一个GET请求，并触发form1 = RegisterForm（）行。我相信我的RegisterForm类有问题，但我无法弄清楚它是什么。我正在使用User模型和UserCreationForm。非常感谢任何帮助。
/ profile / pm /中的KeyError注册用户名＆＃39;

评论是正确的，非常有帮助！我需要将RegisterForm上的“email”字段重命名为“username”：
class RegisterForm(UserCreationForm):
username = forms.EmailField(label = "Email")
first_name = forms.CharField(label = "First name")
last_name = forms.CharField(label = "Last name")
class Meta:
model = User
fields = ("username", "first_name", "last_name")
def clean_email(self):
username = self.cleaned_data['email']
if User.objects.filter(email=email).exists():
raise forms.ValidationError('Email already in use.')
return username
def save(self, commit=True):
user = super(RegisterForm, self).save(commit=False)
user.username = self.cleaned_data["email"]
if commit:
user.save()
return user
答案 1 :(得分：0)
如果UserCreationForm（在您的情况下为USERNAME_FIELD）不是表单字段，则您遇到this issue username崩溃的地方。
该问题仅影响Django 1.10，它不会影响早期版本的Django。它将在即将发布的Django 1.10.1版本中修复。
