如何在 django 忘记密码中添加 "search by usernane or email address" 字段

Question

这是 django 默认的忘记密码表单。如何修改以添加 "search by username" 功能。例如 "username/email"。有人可以帮我弄这个吗。我是 django 的菜鸟。刚开始学习。

def get_users(self, email):

    active_users = UserModel._default_manager.filter(**{
        '%s__iexact' % UserModel.get_email_field_name(): email,
        'is_active': True,
    })
    return (u for u in active_users if u.has_usable_password())

def save(self, domain_override=None,
         subject_template_name='registration/password_reset_subject.txt',
         email_template_name='registration/password_reset_email.html',
         use_https=False, token_generator=default_token_generator,
         from_email=None, request=None, html_email_template_name=None,
         extra_email_context=None):
    """
    Generate a one-use only link for resetting password and send it to the
    user.
    """
    email = self.cleaned_data["email"]
    for user in self.get_users(email):
        if not domain_override:
            current_site = get_current_site(request)
            site_name = current_site.name
            domain = current_site.domain
        else:
            site_name = domain = domain_override
        context = {
            'email': email,
            'domain': domain,
            'site_name': site_name,
            'uid': urlsafe_base64_encode(force_bytes(user.pk)),
            'user': user,
            'token': token_generator.make_token(user),
            'protocol': 'https' if use_https else 'http',
            **(extra_email_context or {}),
        }
        self.send_mail(
            subject_template_name, email_template_name, context, from_email,
            email, html_email_template_name=html_email_template_name,
        )

我们可以在电子邮件字段和 username 字段中搜索 Q objects [Django-doc]:

from django.db.models import <b>Q</b>

def get_users(self, email):
    active_users = UserModel._default_manager.filter(
        <b>Q(**{</b>'%s__iexact' % UserModel.get_email_field_name(): email<b>}) |</b>
        <b>Q(username=email)</b>,
        is_active=True
    )
    return (u for u in active_users if u.has_usable_password())

您可以将 __iexact field lookup [Django-doc] 添加到用户名，因此 username__iexact=email 如果您想以敏感的方式搜索用户名。

在 save 函数中，您可能应该改用用户的 email：

def save(self, domain_override=None,
         subject_template_name='registration/password_reset_subject.txt',
         email_template_name='registration/password_reset_email.html',
         use_https=False, token_generator=default_token_generator,
         from_email=None, request=None, html_email_template_name=None,
         extra_email_context=None):
    """
    Generate a one-use only link for resetting password and send it to the
    user.
    """
    email = self.cleaned_data["email"]
    for user in self.get_users(email):
        if not domain_override:
            current_site = get_current_site(request)
            site_name = current_site.name
            domain = current_site.domain
        else:
            site_name = domain = domain_override
        <b>email = getattr(user, UserModel.get_email_field_name())</b>
        context = {
            'email': email,
            'domain': domain,
            'site_name': site_name,
            'uid': urlsafe_base64_encode(force_bytes(user.pk)),
            'user': user,
            'token': token_generator.make_token(user),
            'protocol': 'https' if use_https else 'http',
            **(extra_email_context or {}),
        }
        self.send_mail(
            subject_template_name, email_template_name, context, from_email,
            email, html_email_template_name=html_email_template_name,
        )
