AttributeError：'Flask'对象没有属性'user_options' [英] AttributeError: 'Flask' object has no attribute 'user_options'

问题描述

所以我试图从下面的文档中设置这个基本的例子：

http://flask.pocoo.org/docs/0.10/patterns/celery/

但到目前为止，我一直得到以下错误：

lockquote
AttributeError：Flask对象没有属性'user_options'

我正在使用celery 3.1.15。
我做了一些在线搜索，但还没有找到正确的答案。
如果有人能说出这点，这将是非常有益的。谢谢

代码：

< pre $ 从芹菜导入芹菜

def make_celery（app）：
芹菜= Celery（app.import_name，broker = app.config ['CELERY_BROKER_URL' ]）
celery.conf.update（app.config）
TaskBase = celery.Task $ b $ class ContextTask（TaskBase）：
abstract = True
def __call __（self ，* args，** kwargs）：
with app.app_context（）：
return TaskBase .__ call __（self，* args，** kwargs）
celery.Task = ContextTask
返回芹菜


示例：

<$ p $从烧瓶导入烧瓶
$ b $ app = Flask（__ name__）
app.config.update（
）CELERY_BROKER_URL ='redis：// localhost：6379 '，
CELERY_RESULT_BACKEND ='redis：// localhost：6379'
）
celery = make_celery（app）

$ b @ celery.task
def add_together（a，b） ：
返回a + b

更新：
修复了这个问题。我正在运行工作不正确。谢谢大家的帮助

解决方案

我看到原来的问题已经解决的更新，但我没有看到确切的解决方案。为了其他人遇到这个错误，这里是一些更多的信息。

基于瓶芹菜背景任务页面（ http://flask.pocoo.org/docs/0.10/patterns/celery/ ）建议您启动芹菜：

celery -A your_application worker

假设代码驻留在application.py中，显式指定了这个代码指向芹菜对象（不只是模块名称）避免了错误：
$ b

celery -A application.celery工人

So I am trying to setup this basic example from the following doc:

http://flask.pocoo.org/docs/0.10/patterns/celery/

But so far I keep getting the below error:

AttributeError: 'Flask' object has no attribute 'user_options'

I am using celery 3.1.15. I did some search online but haven't found the correct answer for this. If someone can shed some light on this, that would be really helpful.Thanks

Code:

from celery import Celery

def make_celery(app):
    celery = Celery(app.import_name, 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 = ContextTask
    return celery

Example:

from flask import Flask

app = Flask(__name__)
app.config.update(
    CELERY_BROKER_URL='redis://localhost:6379',
    CELERY_RESULT_BACKEND='redis://localhost:6379'
)
celery = make_celery(app)


@celery.task()
def add_together(a, b):
    return a + b

Traceback error:

  File "/usr/local/bin/celery", line 11, in <module>
    sys.exit(main())

    argv = self.setup_app_from_commandline(argv)

    user_preload = tuple(self.app.user_options['preload'] or ())
AttributeError: 'Flask' object has no attribute 'user_options'

UPDATE: Fixed the issue. I was running the worker incorrectly.Thanks everyone for your help

解决方案

I see the update that the original question has been solved, but I do not see the exact solution. For the sake of others who run into this error, here is some more info.

The Flask Celery Based Background Tasks page (http://flask.pocoo.org/docs/0.10/patterns/celery/) suggests this to start celery:

celery -A your_application worker

The your_application string has to point to your application’s package or module that creates the celery object.

Assuming the code resides in application.py, explicitly pointing to the celery object (not just the module name) avoided the error:

celery -A application.celery worker
