问题描述
我将Django allauth用作django网站的用户帐户框架。文档显示有一个 ACCOUNT_USERNAME_MIN_LENGTH ，但是没有 ACCOUNT_USERNAME_MAX_LENGTH 由于某种原因。
I'm using Django allauth as my user account framework for my django site. The docs show there is an ACCOUNT_USERNAME_MIN_LENGTH however there is no ACCOUNT_USERNAME_MAX_LENGTH for some reason.
有没有办法为用户名创建最大长度？
Is there any way to create a max length for username?
这是我自定义的allauth注册表单-也许我可以在这里做些什么？
Here's my custom allauth signup form - maybe I can do something here?:
class AllauthSignupForm(forms.Form):
captcha = ReCaptchaField(
public_key=config("RECAPTCHA_PUBLIC_KEY"),
private_key=config("RECAPTCHA_PRIVATE_KEY"),
)
class Meta:
model = User
def signup(self, request, user):
""" Required, or else it throws deprecation warnings """
pass
编辑：试图将SignupView子类化
Trying to subclass SignupView
draft1 / forms.py
class AllauthSignupForm(SignupForm):
def __init__(self, *args, **kwargs):
super(AllauthSignupForm, self).__init__(*args, **kwargs)
self.fields['username']['validators'] += MaxLengthValidator(150,
"Username should be less than 150 character long")
captcha = ReCaptchaField(
public_key=config("RECAPTCHA_PUBLIC_KEY"),
private_key=config("RECAPTCHA_PRIVATE_KEY"),
)
class Meta:
model = User
def signup(self, request, user):
""" Required, or else it throws deprecation warnings """
pass
draft1 / views.py
from allauth.account.views import SignupView
class MySignupView(SignupView):
form_class = AllauthSignupForm
allauth / account / urls.py
url(r"^signup/$", MySignupView.as_view(), name="account_signup"),
草稿1 / settings.py
ACCOUNT_SIGNUP_FORM_CLASS = 'draft1.forms.AllauthSignupForm'
上面的代码返回此错误：
The above code returns this error:

推荐答案
这可以通过扩展 DefaultAccountAdapter 类并覆盖 clean_username 方法。您还需要在自定义验证后再次引用 clean_username 来完成其他内置验证。
This can be quickly done by extending DefaultAccountAdapter class and overriding the clean_username method. You need to also reference the clean_username once again after our custom validation to complete other inbuilt validations.
可以
from allauth.account.adapter import DefaultAccountAdapter
from django.forms import ValidationError
class UsernameMaxAdapter(DefaultAccountAdapter):
def clean_username(self, username):
if len(username) > 'Your Max Size':
raise ValidationError('Please enter a username value less than the current one')
return DefaultAccountAdapter.clean_username(self,username) # For other default validations.
最后，指向您设置中的子类。py
Finally, point to the subclass in your settings.py
ACCOUNT_ADAPTER = 'YourProject.adapter.UsernameMaxAdapter'
