[Answer]-Celery periodic tasks not triggering

Well, as you haven’t provided any code, I will just try to write how I did the similar task you written about. My project structure was like this:

project
  -settings.py
  -manage.py
  -app
    -__init__py
    -celery.py
    -tasks.py
    -views.py
    -models.py

I configured celery in settings.py like this:

from __future__ import absolute_import
BROKER_URL = 'pyamqp://guest:guest@wlocalhost:5672//' #read docs
CELERY_IMPORTS = ('app.tasks', )
from celery.schedules import crontab
from datetime import timedelta

CELERYBEAT_SCHEDULE = {
    'schedule-name': { 
                        'task': 'app.tasks',  # example: 'files.tasks.cleanup'
                        'schedule': timedelta(seconds=30),
                        },
    }

Code of celery.py in app directory:

from __future__ import absolute_import
import os
from celery import Celery
import django
from django.conf import settings
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'settings')
app = Celery('blackwidow.communication.email_sending_method')
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

app.conf.update(
    CELERY_RESULT_BACKEND='djcelery.backends.database:DatabaseBackend',
    )
@app.task(bind=True)
def debug_task(self):
    print('Request: {0!r}'.format(self.request))

And updated the __init__.py file within that directory:–

from __future__ import absolute_import
from celery import app as celery_app

Code of the tasks.py in app directory:

from __future__ import absolute_import
import datetime
from celery.task.base import periodic_task
from django.core.mail import send_mail

@periodic_task(run_every=datetime.timedelta(seconds=30))
def email_sending_method():
        send_mail('subject', 'body', 'from_me@admin.com' , ['to_me@admin.com'], fail_silently=False)

I added respective credentials/configurations for sending mail in settings.py, and then ran this piece of code in command prompt:–

celery -A app worker -B -l info             #I think you missed this.

And that should do the trick, it will send mail after every 30 seconds.
