我正在使用python Flask构建一个网站.一切都很顺利,现在我正在努力实施芹菜.

在我尝试使用来自芹菜的烧瓶邮件发送电子邮件之前,情况也很顺利.现在我得到一个"在应用程序上下文之外工作"的错误.

完全追溯是

  Traceback (most recent call last):

我有一个具有 MVC 结构的 Flask 应用程序：

my_app
??? server.py
??? requirements.txt
??? models
?   ??? __init__.py
    ??? model.py
??? controllers
    ??? __init__.py
    ??? client_controllers
        ???controller.py
    ??? another_controller.py
??? templates

我使用蓝图在“控制器”中拆分服务器代码，所以我有这样的事情：

服务器.py：

from flask import Flask
from celery import Celery

from controllers.client_controllers.controller import controller

app = Flask(__name__)
app.secret_key = 'SECRET'

app.register_blueprint(controller)

# Celery Configuration
def make_celery(app):

    celery = Celery(app.import_name, backend=app.config['CELERY_RESULT_BACKEND'],
                    broker=app.config['CELERY_BROKER_URL'])
    celery.conf.update(app.config)
    TaskBase = celery.Task
    class ContextTask(TaskBase):
        abstract = True
        def __call__(self, *args, **kwargs):
            with app.app_context():
                return TaskBase.__call__(self, *args, **kwargs)
    celery.Task = …
