Background Tasks with Celery & Redis

🐍 DjangoLesson 14Advanced

Celery enables you to delegate slow execution tasks (sending emails, image processing, or data imports) to background worker queues, keeping the main request-response cycle fast.

1 Creating Celery Tasks

Python — tasks.py

from celery import shared_task
from django.core.mail import send_mail

@shared_task
def send_welcome_email(email):
    send_mail(
        "Welcome",
        "Thank you for registering!",
        "noreply@example.com",
        [email],
        fail_silently=False,
    )
