NameError django send_mail

Question

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

来自我的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.'),

您发布了模特的代码。

我认为

classifieds/views/create.py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个东西而不是..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发生在类而不是方法中。查看来源，您会发现它位于Payment.complete方法中：https://github.com/saebyn/django-classifieds/blob/master/classifieds/models.py#L273

此处使用

send_mail： https://github.com/saebyn/django-classifieds/blob/master/classifieds/views/create.py#L116

但未导入，请将其导入。

在项目设置中使用它们。py：

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'yourusername'
EMAIL_HOST_PASSWORD = 'YourPassword'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

在您的控制器中使用：

from django.core.mail import send_mail

send_mail('Subject here', 'Here is the message.', 'from@example.com', ['to@example.com'], fail_silently=False)

尝试使用以下命令替换send_mail函数：

django.core.mail.send_mail(your_parameters)

此外，您在send_mail中的第一个参数似乎不是字符串，请更改为：（https://docs.djangoproject.com/en/dev/topics/email/?from=olddocs)

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

尝试这两个建议，让我知道你得到了什么。
