django-allauth - Django-Allauth 中的自定义表单验证

Question

我想对 django-allauth 中的字段进行一些额外的验证。例如，我想阻止使用免费电子邮件地址。所以我想在注册时运行这个方法

def clean_email(self):
    email_domain = self.cleaned_data['email'].split('@')[1]
    if email_domain in self.bad_domains:
        raise forms.ValidationError(_("Registration using free email addresses is prohibited. Please supply a different email address."))

同样，我想对电子邮件地址以外的不同字段运行自定义验证。我该如何执行此操作？

allauth 配置上有一些适配器。例如这个:

ACCOUNT_ADAPTER (="allauth.account.adapter.DefaultAccountAdapter")
    Specifies the adapter class to use, allowing you to alter certain default behaviour.

您可以通过覆盖默认适配器来指定新适配器。只需覆盖 clean_email 方法。

class MyCoolAdapter(DefaultAccountAdapter):

    def clean_email(self, email):
        """
        Validates an email value. You can hook into this if you want to
        (dynamically) restrict what email addresses can be chosen.
        """
        *** here goes your code ***
        return email

然后修改settings.py上的ACCOUNT_ADAPTER

ACCOUNT_ADAPTER = '**app**.MyCoolAdapter'
