Reverts commit 4d69165ab6. Now that a
release has this option, it's ok to show it in the docs. It had been
reverted because the 2.2.x docs showed it before 2.2.3 was released.

Background Tasks with Celery
|
|
============================
|
|
|
|
This example shows how to configure Celery with Flask, how to set up an API for
|
|
submitting tasks and polling results, and how to use that API with JavaScript. See
|
|
[Flask's documentation about Celery](https://flask.palletsprojects.com/patterns/celery/).
|
|
|
|
From this directory, create a virtualenv and install the application into it. Then run a
|
|
Celery worker.
|
|
|
|
```shell
|
|
$ python3 -m venv .venv
|
|
$ . ./.venv/bin/activate
|
|
$ pip install -r requirements.txt && pip install -e .
|
|
$ celery -A make_celery worker --loglevel INFO
|
|
```
|
|
|
|
In a separate terminal, activate the virtualenv and run the Flask development server.
|
|
|
|
```shell
|
|
$ . ./.venv/bin/activate
|
|
$ flask -A task_app run --debug
|
|
```
|
|
|
|
Go to http://localhost:5000/ and use the forms to submit tasks. You can see the polling
|
|
requests in the browser dev tools and the Flask logs. You can see the tasks submitting
|
|
and completing in the Celery logs.
