django 内置 password_reset 从 send_email 更改连接

django built-in password_reset change connection from send_email

在我的应用程序中,我使用了内置的授权视图。我还使用 django-anymail 的邮戳连接来发送一些用户电子邮件通知。

Example: 

email_backend = get_connection('anymail.backends.postmark.EmailBackend')
   mail = EmailMessage(
   subject=subject,
   body=message,
   to=[settings.DEFAULT_FROM_EMAIL],
   connection=email_backend
   )

我想在 PasswordResetView 中更改发送电子邮件所用的连接。有什么方法可以像我给 html_email_template_name='...'success_url='...' 一样在 PasswordResetView.as_view() 中给关键字参数吗?还是我必须重写 PasswordResetView?

您不必更改 PasswordResetView,但您必须创建一个自定义 PasswordResetForm,然后您可以将其作为关键字参数传递给 PasswordResetView.as_view()

如果您查看 PasswordResetView 的源代码,您会发现它实际上并没有发送电子邮件本身。电子邮件发送是作为 PasswordResetForm.save() 的一部分完成的,它调用 PasswordResetForm.send_mail()

您可以继承 PasswordResetForm 并覆盖 .send_mail() 以使用您的自定义电子邮件后端:

from django.contrib.auth.forms import PasswordResetForm

class PostmarkPasswordResetForm(PasswordResetForm):
    def send_mail(self, subject_template_name, email_template_name,
                  context, from_email, to_email, html_email_template_name=None):
        """
        Send a django.core.mail.EmailMultiAlternatives to `to_email` using
        `anymail.backends.postmark.EmailBackend`.
        """
        subject = loader.render_to_string(subject_template_name, context)
        # Email subject *must not* contain newlines
        subject = ''.join(subject.splitlines())
        body = loader.render_to_string(email_template_name, context)

        email_backend = get_connection('anymail.backends.postmark.EmailBackend')

        email_message = EmailMultiAlternatives(subject, body, from_email, [to_email], connection=email_backend)
        if html_email_template_name is not None:
            html_email = loader.render_to_string(html_email_template_name, context)
            email_message.attach_alternative(html_email, 'text/html')

        email_message.send()
