# Dynamically update periodic tasks in Celery and Django

Example project showing how to dynamically add and remove periodic tasks in Celery and Django. It is using `PeriodicTask` class from [**`django-celery-beat`**](https://github.com/celery/django-celery-beat) package.

This example repository is very simple demo of [uptime monitoring service](https://monitor-uptime.com). User can add server address and interval at which server uptime status will be checked. Tasks can be dynamically added or removed.

You can read more about [dynamic periodic tasks in the article](https://saasitive.com/tutorial/dynamically-update-periodic-tasks-celery/).

## Sequence diagram of uptime monitoring

    actor U as User

    participant S as Server

    participant DB as Database

    participant B as Celery Beat

    participant W as Celery Worker

    

    U->>S: Create monitor 

    Note right of S: Create objects in DB

    S->>DB: Create Monitor object

    S->>DB: Create IntervalSchedule object

    S->>DB: Create Periodictack object

    

    loop every beat period

        DB->>B: Get info about periodic tasks

    end

    loop Every interval period

        B->>W: Create task

        Note right of W: Execute task

        W->>DB: Save task result (request data)

    end
