title: In celery 3.1, making django periodic task
body: <p>Things changed too much in Django, so I can't use 3.1. I need some help.</p>
  
  <p>I read about <a href="http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html#django-first-steps" rel="noreferrer">make a task in django</a>, and read <a href="http://docs.celeryproject.org/en/latest/userguide/periodic-tasks.html" rel="noreferrer">Periodic Tasks</a> document. But I don't know how make periodic tasks in django. I think this becuase of my low level English..</p>
  
  <p>In the older version of Celery, I imported <em>djcelery</em>&amp;<em>crontab</em> and set CELERYBEAT_SCHEDULE in <em>settings.py</em>, and excuted by <em>manage.py</em>.</p>
  
  <p>But it seems that I cannot execute celery deamon by that way anymore. Than where I should put CELERYBEAT_SCHEDULE? In django example in docs, they set <code>os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings')</code>
   in <em>proj/proj/celery.py</em>. (1) So setting celerybeat in <em>settings.py</em>(like before) is ok?</p>
  
  <p>(2) If you can, a tiny example of making periodic task in django will very helpful. When I was reading tutorials, the most confusing part was <em>File Path</em>. If you don't want to provide a whole example, I will really appreciate if you explain about where I should make tasks, set beat, and executed deamon.</p>
  
  <p>Thanks for reading.</p>
