# Common app
|
|
|
|
Common app provide common view, function or others.
|
|
|
|
Common app shouldn't rely on other apps, because It may lead to cycle
|
|
import.
|
|
|
|
If your want to implement some function or class, you should think
|
|
whether other app use or not. If yes, You should make in common.
|
|
|
|
If the ability more relate to your app tightness, It's mean your app
|
|
provide this ability, not common, You should write it on your app utils.

## Celery usage
|
|
|
|
|
|
JumpServer use celery to run task async. Using redis as the broker, so
|
|
you should run a redis instance
|
|
|
|
#### Run redis
|
|
|
|
$ yum -y install redis
|
|
|
|
or
|
|
|
|
$ docker run -name jumpserver-redis -d -p 6379:6379 redis redis-server
|
|
|
|
|
|
#### Write tasks in app_name/tasks.py
|
|
|
|
ops/tasks.py
|
|
|
|
```
|
|
from __future__ import absolute_import
|
|
|
|
import time
|
|
from celery import shared_task
|
|
from common import celery_app
|
|
|
|
|
|
@shared_task
|
|
def longtime_add(x, y):
|
|
print 'long time task begins'
|
|
# sleep 5 seconds
|
|
time.sleep(5)
|
|
print 'long time task finished'
|
|
return x + y
|
|
|
|
|
|
@celery_app.task(name='hello-world')
|
|
def hello():
|
|
print 'hello world!'
|
|
|
|
```
|
|
|
|
#### Run celery in development
|
|
|
|
```
|
|
$ cd apps
|
|
$ celery -A common worker -l info
|
|
```
|
|
|
|
#### Test using task
|
|
|
|
```
|
|
$ ./manage.py shell
|
|
>>> from ops.tasks import longtime_add
|
|
>>> res = longtime_add.delay(1, 2)
|
|
>>> res.get()
|
|
```
