我正在使用Miguel Grinberg的文章使用应用工厂模式设置Celery,以便使用Flask-Mail发送电子邮件.我一直在调用使用Celery的各种脚本而没有任何问题.但是Runtime Error: working outside of application context,即使我在应用程序上下文中运行worker,我也会继续执行以下任务.为什么我收到此错误？如何让Flask-Mail在Celery中运行？

email.py:

from flask import current_app, render_template
from flask.ext.mail import Message
from . import celery, mail

@celery.task
def send_async_email(msg):
    mail.send(msg)

def send_email(to, subject, template, **kwargs):
    with current_app.test_request_context(): # used app_context() as well.
        msg = Message(current_app.config['PORTAL_MAIL_SUBJECT_PREFIX'] + ' ' +                                       subject,
                  sender=current_app.config['PORTAL_MAIL_SENDER'], recipients=[to])
        msg.body = render_template(template + '.txt', **kwargs)
        msg.html = render_template(template + '.html', **kwargs)
        send_async_email.delay(msg)

__init__.py:

from flask import Flask
from celery import Celery
from flask.ext.mail import …
