django内置了来自password_reset的send_email更改连接

Question

在我的应用程序中，我使用内置的auth视图。我还使用一个使用django-anymail的邮戳连接来通知一些用户电子邮件。

Example: 

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

我想改变我用PasswordResetView发送电子邮件的连接。有任何方法可以在PasswordResetView.as_view()中给出关键字参数，就像给html_email_template_name='...'或success_url='...'那样吗？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，然后将其作为关键字参数传递给PasswordResetView.as_view()。

如果你看一下PasswordResetView的源代码，你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，后者调用PasswordResetForm.send_mail()

您可以子类PasswordResetForm和改写.send_mail()来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()
