如何在用户界面中显示Django ValidationError

我对如何在注册页面显示ValidationError时感到困惑，只要密码和密码确认不是相同的，而是将我发送到说ValueError和东西的页面。但是，当我到达管理员时，它肯定会显示ValidationError。任何帮助？这里是我的代码如何在用户界面中显示Django ValidationError

forms.py

from django.core.exceptions import ValidationError 
from django.core.validators import RegexValidator

`从django.core进口验证

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

views.py

 from django.contrib.auth.forms import UserCreationForm 
     from django.contrib.auth.models import * 
     from django.contrib   import messages 
     from django.core import validators 

    def signup(request): 

if request.method == 'POST':  
    form = AccountForm(request.POST)  
    # form = UserCreationForm(request.POST) 
    if form.is_valid: 
     username = request.POST.get("username") 
     email = request.POST.get("email") 
     password1 = request.POST.get("password1") 
     password2 = request.POST.get("password2") 

     # form.clean_password2() 
     form.save() 

    return HttpResponseRedirect('/login/') 
else: 
    form = AccountForm() 
    # form = UserCreationForm() 

return render(request, 'accounts/signup.html', {'form':form})

我认为您的代码存在问题。无论form.is_valid的结果如何，它都会重定向到登录。是对的吗？ – Nick

没有。如果密码和密码确认不相同，它将发送到错误页面，并在/ signup /处指出ValueError。 – user3385560
