我一直在尝试安排芹菜在后台执行的任务，但我一直遇到问题。

到目前为止我所做的快速参考

我安装celery并django-celery通过easy_install，添加到INSTALLED_APPS：

'djcelery',
'kombu.transport.django',

导入以下内容并运行syncdb：

 import djcelery
 djcelery.setup_loader()
 BROKER_URL = "django://"

我试图在后台运行的任务是密码重置。因此，当用户忘记密码时，我想让发送电子邮件任务在后台运行，所以我所做的就是将我的 forgot_password 函数从其中views.py移入tasks.py，以便它可以运行。

我的tasks.py：

 from django.contrib.auth.views import password_reset
 from django.shortcuts import render
 from celery.decorators import task

 @task()
 def forgot_password(request):
     if request.method == 'POST':
         return password_reset(request,
             from_email=request.POST.get('email'))
     else:
         return render(request, 'forgot_password.html')

他们views.py现在什么都没有。

问题是，即使我丢失了密码，我也可以发送电子邮件。我不确定它是否在后台运行。我所做的检查是：

 manage.py celery worker --loglevel=info

但我收到一个错误KeyError: 'processName'：：

 C:\o\17\mysite>manage.py celery worker --loglevel=info

有人可以告诉我是否将忘记密码配置为在后台发送电子邮件以及为什么会出现此错误，请帮助我KeyError: 'processName'？

首先，有一种使用 celery 发送电子邮件的简单方法：

django-celery-email

其次，你的任务是错误的。任务是后台作业，而不是视图。它应该执行最后的操作。在您的情况下，这是发送电子邮件
