Integrating 🔗 Celery with Django via Redis server ,To-Do asynchronously 👀task without stopping the main-flow 📃 of Django-project .It increase your speed 🚀 and user experience 🤵 of website . This repo explain how to setup Celery,and integrate it with the Django-Framework.

Note : Steps to steup Celery on production-side is different

Approach 🏁

Celery package help us to asynchronous tasks on different worker 🖥️ ,That is on Redis server. The Celery also have some great features in scheduling 🕐 task after a certain period of time. The tasks are excuted on different server (Redis server), and are not run on Django-Server.If we run long and complicated tasks on django server it will reduced the efficiency of website

Modern users expect pages to load instantaneously ⚡, to solve this we consider many solutions like multiprocessing, multithreading 🧵, asynchronous functions using async/await or the Message Queues.

Installation/Dependencies 💾

Use the package manager pip to install the following modules and packages.

pip install -r requirements.txt

Download Redis server form here ⬇️

Usage 🔭

Open terminal and write following commands 📝

To run Celery worker

celery -A your_django_project_name.celery worker --pool=solo -l info

And in separate terminal run django server

python manage.py runserver

Updating SMTP settings for sending mails 📨

Change the settings for the sender-mail credential in the settings.py file , enter the sender mail and sender mail-password (SMTP configuartion)

Making tasks 📖

Task are python functions which can be called in the django-project and also be scheduled at particular time. Task-function can be written in task.py file and can be imported anywhere in the project

@task()
def Send_Mail_With_Celery(email):
  your function goes here....
  return "done"

calling function

Send_Mail_With_Celery.delay(args)

Purpose 📢

Increase Speed ⚡ and User-experience of website

Sending mail using Celery 👀

Sending mail without using Celery ⌛

NOTE the difference : Celery does not stoped the next page from loading and done the task on worker whereas Without using Celery it took almost 3 seconds ⌛ , to load next page

This is just a small-function but imagine making operations on large user-database ,it would be not good ☹️
