Question

经过几个小时的拔毛，我期待stackoverflow来帮助我解决这个问题。

我创建了两个信号来运行自动电子邮件功能。通过修改admin.py文件中的save_model来触发信号。

唯一的问题是......当通过Django开发服务器（发送自动电子邮件）时，信号同时工作，但在远程服务器上进行测试时，只有一个信号有效。我不明白这是怎么可能的，我也找不到这个错误。

我知道这里没有太多信息可以使用。对于这里可能发生的事情的任何建议？

对于文件/目录结构，这些信号保存在位于此特定应用程序目录中的signals.py文件中。通过修改admin.py文件中的save_model定义，在同一目录中触发该信号。

以下是信号定义：

notify_status_change_signal = Signal(providing_args=['status', 'restaurant', 'delivery_date', 'contact_email', 'contact_phone'])
notify_on_change_signal = Signal(providing_args=['organization', 'identifier', 'id', 'restaurant', 'delivery_date'])

@receiver(notify_on_change_signal)
def notify_on_change(sender, organization, identifier, id, restaurant, delivery_date, signal, *args, **kwargs):
    "This is the signal that only functions when run through the local development server"
    order_id = identifier + str(id)
    subject = r'A change has been made to order %s' % order_id
    body = """
    System Message: The details for order %s (%s) have been updated by the client.""" % (order_id, organization)

    send_mail(subject, body, 'System Notification <system@expressdelivery.com>', [admin_email], fail_silently=False)    


@receiver(notify_status_change_signal)
def notify_status_change(sender, status, restaurant, delivery_date, contact_email, contact_phone, signal, *args, **kwargs):
    """This is the signal that works on both servers"""
    stat_body = {
    'Confirmed':"""

Message 1 """,

    'Placed': """

Message 2 """,

    'En Route': """

Message 3 """,

    'Completed':"""

Message 4 """,
    }

    #Auto email
    from_addr = 'Order Status <status@expressdelivery.com>'
    to_addrs = [contact_email]
    subject = u'Order %s %s status changed to %s.' % (restaurant, delivery_date, status)
    body = ''
    for stat_label, description in stat_body.iteritems():
        if status == stat_label: body = description

    if status == "Confirmed" or status == "En Route" or status == "Completed":    
        send_mail(subject, body, from_addr, to_addrs, fail_silently=False)

    #Auto text message
    if status == 'En Route':
        client = TwilioRestClient(settings.TWILIO_ACCOUNT_SID, settings.TWILIO_AUTH_TOKEN)
        message = client.sms.messages.create(to=contact_phone,
                                     from_="5555555555",
                                     body="Your order, %s %s, is now en route." % (restaurant, delivery_date))

Answer 1

虽然我在使用这些信号更新代码时确实重新启动了服务器，但重新启动服务器再次成功了。
