python - NameError Django send_mail

Question

为什么我会收到 NameError:global name 'send_mail' is not defined ?

从我的models.py:

from django.template import Context, loader
from django.utils.translation import ugettext as _
from django.core.mail import send_mail
.......
class Payment(models.Model):    

    # send email for payment
    # 1. render context to email template
    email_template = loader.get_template('classifieds/email/payment.txt')
    context = Context({'payment': self})
    email_contents = email_template.render(context)

    # 2. send email
    send_mail(_('Your payment has been processed.'),
              email_contents, settings.FROM_EMAIL,
              [self.ad.user.email], fail_silently=False)

谢谢!

回溯来自您的观点。

File "/home/.../webapps/django/myproject/classifieds/views/create.py" in checkout
  122.       send_mail(_('Your ad will be posted shortly.'),

您发布了模型中的代码。
classifieds/views/create.py我认为没有导入 send_mail。

另一个问题是为什么你在你的模型类上做这些事情而不是......在模型方法中......

编辑:你把它放在问题中的方式让它看起来非常奇怪，这个发送邮件的东西是在类上而不是在方法中发生的。查看源代码，您会看到它在 Payment.complete 中方法: https://github.com/saebyn/django-classifieds/blob/master/classifieds/models.py#L273
send_mail在这里使用:
https://github.com/saebyn/django-classifieds/blob/master/classifieds/views/create.py#L116

但不是进口的，进口吧。
