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

Question

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

But so far I keep g

Answer 1

like this:

celery -A your_application worker

where your_application stands:

your_application = Flask(\__name\__)

the python file name: your_application.py, it will work

By the way, celery v4 is unsupported in Windows

Answer 2

The Flask Celery Based Background Tasks page (http://flask.pocoo.org/docs/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

Answer 3

This worked for me:

celery -A my_app_module_name.celery worker

Answer 4

rename app flask_app It will work
