我在 Django 1.5.1 中有以下环境：
表格.py
class UserForm(forms.ModelForm):
class Meta:
model = User
widgets = {
'username': forms.TextInput(attrs={'class': 'input-xlarge', 'placeholder': 'Email Address'}),
'first_name': forms.TextInput(attrs={'class': 'input-xlarge', 'placeholder': 'First Name'}),
'last_name': forms.TextInput(attrs={'class': 'input-xlarge', 'placeholder': 'Last Name'}),
'mobile_phone': forms.TextInput(attrs={'class': 'input-xlarge', 'placeholder': 'Mobile Phone'}),
'office_phone': forms.TextInput(attrs={'class': 'input-xlarge', 'placeholder': 'Office Phone'}),
}
GROUP_CHOICES = [(-1, '[Select]')]
GROUP_CHOICES += [(group.id, group.name.capitalize()) for group in Group.objects.all()]
username = forms.EmailField(
label='Email Address',
required=True,
validators=[validate_email],
widget=forms.TextInput(attrs={'class': 'input-xlarge', 'placeholder': 'Email Address'})
)
password1 = forms.CharField(
label='Password',
widget=forms.PasswordInput(attrs={'class': 'input-xlarge', 'placeholder': 'Password'})
)
password2 = forms.CharField(
label='Password confirmation',
widget=forms.PasswordInput(attrs={'class': 'input-xlarge', 'placeholder': 'Password confirmation'})
)
group = forms.ChoiceField(
label='Group',
choices=GROUP_CHOICES
)
def clean_password2(self):
password1 = self.cleaned_data.get('password1')
password2 = self.cleaned_data.get('password2')
if password1 and password2 and password1 != password2:
raise forms.ValidationError('Passwords don\'t match')
return password2
def clean_group(self):
if self.cleaned_data['group'] == '-1':
raise forms.ValidationError('This field is required.')
return self.cleaned_data['group']
def clean_first_name(self):
if self.cleaned_data['first_name'] == '':
raise forms.ValidationError('This field is required.')
return self.cleaned_data['first_name']
def clean_last_name(self):
if self.cleaned_data['last_name'] == '':
raise forms.ValidationError('This field is required.')
return self.cleaned_data['last_name']
def save(self, commit=True):
user = super(UserForm, self).save(commit=False)
user.set_password(self.cleaned_data['password1'])
user.username = self.cleaned_data['username']
if commit:
user.save()
user.groups.clear()
user.groups.add(self.cleaned_data['group'])
user.save()
return user
模型.py
class User(auth.models.User):
mobile_phone = models.CharField(
verbose_name='Mobile Phone',
max_length=50
)
office_phone = models.CharField(
verbose_name='Office Phone',
max_length=50
)
我更改*auth_user* 以允许我插入长度超过 30 个字符的用户名，这样我就可以使用电子邮件作为用户名（我已经尝试过使用OneToOneField和自定义模型，这些方法导致我的工作比预期的要多，所以我不会采取那种方式）
我的问题：
- 我必须添加 first_name 和 last_name 清理器，因为 auth.models.User 没有它们，并且小部件对象不允许我设置必需的属性，这是最好的方法吗？
- 我只有一个问题，用户名字段的MaxValueValidator设置最多仍为30。我怎么能在不覆盖它的情况下消失它。由于我使用的是基于类的视图，当我尝试通过UpdateView类更新表单时，覆盖字段不会使用模型数据启动用户名字段，将其留空。其余字段没有任何问题
如果我的英语看起来很难看，谢谢和抱歉！
