My celery redis task isn't working in my django app on heroku server

I have a task that was working fine on my local server but when I pushed it to Heroku, nothing happens. there are no error messages. I am a newbie when it comes to this and locally I would start the worker by doing

celery worker -A blog -l info. 

So I'm guessing that's the issue may have to do with that. because I don't know to do this. I doubt I'm supposed to do this in my app. heres my code

celery.py

import os

from celery import Celery

from django.conf import settings

# set the default Django settings module for the 'celery' program.
os.environ.setdefault(
    'DJANGO_SETTINGS_MODULE', 'gettingstarted.settings'
)

app = Celery('blog')

# Using a string here means the worker will not have to
# pickle the object when using Windows.
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

my tasks.py

import requests
import random
import os

from bs4 import BeautifulSoup
from .celery import app
from .models import Post
from django.contrib.auth.models import User

my views.py

def shopan(request):
    the_star.delay()
    return redirect('/')

I have multiple instances of REDIS_URL

soI ran

heroku redis:promote REDIS_URL

and that's what I use in my environment variable which you can see above. How can i make this work?
