Checking Whether a Celery Task is Already Running

#python #django #celery

Ever tried to check whether a Celery task is already running?
Here is the piece of code I created for checking whether a task is running by its name.

from celery import current_app


class CeleryHelper:
    """Contains helper functionalities to be used while interacting with Celery."""
    @staticmethod
    def is_being_executed(task_name: str) -> bool:
        """Returns whether the task with given task_name is already being executed.

        Args:
            task_name: Name of the task to check if it is running currently.
        Returns: A boolean indicating whether the task with the given task name is
            running currently.
        """
        active_tasks = current_app.control.inspect().active()
        for worker, running_tasks in active_tasks.items():
            for task in running_tasks:
                if task["name"] == task_name:
                    return True

        return False

I searchedd for that a while ago and I couldn't really find a direct way to do that in a Django project but the above code is tested and works in Django-based projects.
