Running linod¶
In a development environment you might want to run linod
when you are developing or testing one of your applications.
Usage for developers¶
Before running linod for the first time, you need to install
the Python package schedule written by Daniel Bader:
$ . env/bin/activate
$ pip install schedule
Now you simply go to your project directory and invoke the admin command:
$ cd ~/projects/mysite
$ python manage.py linod
This process will run as long as you don't kill it, e.g. until you hit Ctrl-C.
What it does¶
The linod command is responsible for running the scheduled
background jobs defined by your application. This includes for
example:
Send out emails for notifications
Run nightly maintenance tasks such as
checkdataorchecksummaries.
You can see a list of these jobs by running:
$ cd ~/projects/mysite
$ python manage.py linod --list
Applications can register these jobs either using the schedule API
directly, but Lino itself differentiates two types of background
tasks: "often" and "daily".
dd.api.schedule_often()
dd.api.schedule_daily()
