在Flask中开始Celery：AttributeError：“ Flask”对象没有属性“ user_options”

Question

我尝试从命令行启动Celery辅助服务器：

celery -A server application worker --loglevel=info

代码和文件夹路径：

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"

追溯：

在终端中运行celery工人时出现此错误。

只需使用此命令而不是您的命令运行celery：

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，如果您想在add_together函数中包含自变量，则应声明如下任务：

@celery.task(bind=True)
