当密码和密码确认不相同时，我对如何在我的注册页面中显示 ValidationError 感到困惑，而不是将我发送到显示 ValueError 和其他东西的页面。但是，当我到管理员那里时，它肯定会显示 ValidationError。有什么帮助吗？这是我的代码
表格.py
from django.core.exceptions import ValidationError
from django.core.validators import RegexValidator
` 从 django.core 导入验证器
class AccountForm(UserCreationForm):
email = forms.EmailField(required=True)
class Meta:
model = User
fields = ("username", "email", "password1", "password2")
# def save(self, commit=True):
# user = super(AccountForm, self).save(commit=False)
# user.email = self.cleaned_data["email"]
# if commit:
# user.save()
# return user
def clean_password2(self):
password1 = self.cleaned_data.get("password1")
password2 = self.cleaned_data.get("password2")
if not password2:
raise forms.ValidationError(
self.error_messages['Must input Password Confirmation'],
code='Password_Confirmation_empty')
if password1 != password2:
raise forms.ValidationError(
self.error_messages['Passwords do not match.'],
code='password_mismatch')
password_validation.validate_password(
self.cleaned_data.get('password2'), self.instance)
return password2
def save(self, commit=True):
user = super(AccountForm,self).save(commit=False)
user.email = self.cleaned_data["email"]
user.set_password(self.cleaned_data["password1"])
if commit:
user.save()
return user
视图.py
