自定义模型的 Django UserCreationForm 正在输出 3 个密码字段密码、密码 1 和密码 2

Question

好的，所以我有一个基于 AbstractUser 的用户注册表单，它替换了我的 settings.py 中的 Django 模型，当我测试用户的注册表单时，该模型只添加了我需要的用户信息的几个字段没有被创建，我调试并发现最后一次登录和日期都在需要的地方加入，所以我将它们设置为隐藏输入，值为

{% now "SHORT_DATE_FORMAT" %} 

解决了前两个错误，但是还有第三个错误说字段密码是必需的，即我的表单要求我输入密码、密码 1 和密码 2

非常感谢您的帮助！

这是我的观点.py

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)

        if form.is_valid():
            new_user = form.save(commit=False)
            new_user.is_active = True
            new_user.save()
            group = Group.objects.get(name='Usuario')
            new_user.groups.add(group)
            return HttpResponseRedirect('/')

   else:
       form = UserRegisterForm()

   return render_to_response('register.html', locals(), RequestContext(request))

这是我的模特

class SiteUser(AbstractUser):
    descripcion = models.TextField(blank=True, null=True)
    direccion = models.CharField(max_length=255, blank=True, null=True)
    image = models.ImageField(upload_to='imagenes_usuarios', blank=True, null=True)
    thumbnail = models.ImageField(upload_to='imagenes_usuarios/thumbs', blank=True, null=True)
    slug = models.SlugField(default='', blank=True)

Forms.py

class UserRegisterForm(UserCreationForm):
    class Meta:
        model = SiteUser

    def clean_username(self):
        username = self.cleaned_data["username"]
        try:
            # Not sure why UserCreationForm doesn't do this in the first place,
            # or at least test to see if _meta.model is there and if not use User...
            self._meta.model._default_manager.get(username=username)
        except self._meta.model.DoesNotExist:
            return username
        raise forms.ValidationError(self.error_messages['duplicate_username'])

这是我的模板

由于您使用的是 UserCreationForm，它需要所有字段来验证和保存表单，为什么不试试 ModelForm。
