在烧瓶中启动芹菜：AttributeError：'Flask'对象没有属性'user_options' [英] Starting celery in flask: AttributeError: 'Flask' object has no attribute 'user_options'

问题描述

  celery -A服务器应用程序工作者--loglevel = info 
  

代码和文件夹路径：

 server.py 
 application / controllers / routes.py 
  

$ b

  app =应用程序中的Flask（__ name__）
。控制器导入路由
 app.run（host ='127.0.0.1'，port = 5051，debug = True）
  

route.py

  from flask import Flask，
 from celery import celery 
 from server import app 
 
 
 app.config ['CELERY_BROKER_URL'] ='redis：// localhost：6379/0'
 app.config ['CELERY_RESULT_BACKEND'] ='redis：// localhost：6379/0'
 $ b $ celery = celery（app.name，broker = app.config ['CELERY_BROKER_URL']）
 celery。 conf.update（app.config）
 
 @ celery.task（）
 def add_toge （自我，计数）：
返回第一次成功
 
 @ app.route（/ queing）
 def testsfunction（）：
 count = 1 
 add_together.delay（count）
 returncool

在终端中运行一个芹菜工。

解决方案

使用这个命令运行芹菜而不是你的：

  celery -A application.controllers.routes：celery worker --loglevel = info 
  

这将解决您当前的问题，但是您的代码有很多错误，例如，如果您希望在 add_together 函数你应该声明一个这样的任务：

  @ celery.task（bind = True）
  

I try to start a Celery worker server from a command line:

celery -A server application worker --loglevel=info  

The code and folder path:

server.py  
application/controllers/routes.py

server.py

app = Flask(__name__)  
from application.controllers import routes  
app.run(host='127.0.0.1',port=5051,debug=True)

route.py

from flask import Flask,  
from celery import Celery
from server import app 


app.config['CELERY_BROKER_URL'] = 'redis://localhost:6379/0'
app.config['CELERY_RESULT_BACKEND'] = 'redis://localhost:6379/0' 

celery = Celery(app.name, broker=app.config['CELERY_BROKER_URL'])
celery.conf.update(app.config)

@celery.task()  
def add_together(self, count):  
   return "First success"

@app.route("/queing")  
def testsfunction():    
    count = 1  
    add_together.delay(count)  
    return "cool"

Trace back:

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

I got this error when I'm running a celery worker in terminal.

解决方案

just run the celery with this command instead of yours:

celery -A application.controllers.routes:celery worker --loglevel=info

this will solve your current problem however your codes have a plenty of mistakes for example if you want to have a self argument inside your add_together function you you should declare a task like this:

@celery.task(bind=True)
