Project description

django-simpletask

Django application provides simple task model, admin, server services and client service.

Install

pip install django-simpletask

Usage

pro/settings

INSTALLED_APPS = [
    'django_db_lock',
    'django_simpletask',
]

DJANGO_SIMPLETASK_ACLKEY = "TsE9Jd3TrUtTA9wjGCLXoDqh891srpyo"

Note:

  • Mostly you need a lock service, so we add django_db_lock in INSTALLED_APPS.
  • Set DJANGO_SIMPLETASK_ACLKEY to your own aclkey. It will be used in task executor.

app/models.py

from django_simpletask.models import SimpleTask


class Task(SimpleTask):
    title = models.CharField(max_length=64)

    class Meta:
        permissions = [] + SimpleTask.Meta.permissions

    def do_task_main(self):
        return "done!"

Note:

  • Write your own task model based on SimpleTask.
  • Add task reset permission.
  • Implement you own do_task_main.

app/admin.py

from django.contrib import admin
from .models import Task

class TaskAdmin(admin.ModelAdmin):
    list_display = ["title", "status"]
    readonly_fields = [] + Task.SIMPLE_TASK_FIELDS

Note:

  • Mostly we don't want to change anything inside task, so we set task fields readonly.

task_executor.py

from daemon_application.app import DaemonApplication
from django_simpletask.services import SimpleTaskService

class TaskExcutor(DaemonApplication):
    def main(self):
        service = SimpleTaskService("http://127.0.0.1:8000/example/task/services/", aclkey="TsE9Jd3TrUtTA9wjGCLXoDqh891srpyo")
        service.start()
        service.join()

app = TaskExcutor().get_controller()

if __name__ == "__main__":
    app()

Note:

  • Add task_executor.py script.
  • Set the server to your own url.
  • Set the aclkey match the DJANGO_SIMPLETASK_ACLKEY setting.
