The Ultimate Guide to Deploying Django Apps on Render

Deployment is a critical step in the journey of every Django web application. Taking an app from local development to a live production environment can be daunting, especially for beginners.

Many developers struggle with deployment due to the complexities of server setup, configurations, and ongoing maintenance. This is where Render comes to the rescue!

In this ultimate guide, we‘ll dive deep into deploying Django applications on Render‘s fully-managed cloud platform. Whether you‘re a seasoned Django developer or just getting started, this article will walk you through the process step-by-step.

Why Django and Render Are a Perfect Match

Django is a powerful, high-level Python web framework that encourages clean design and rapid development. Since its creation in 2005, Django has become a go-to choice for building web applications of all sizes and industries.

According to the Django Software Foundation, Django now powers over 12,000 known websites including Instagram, Disqus, Bitbucket, and NASA. The framework‘s popularity continues to grow thanks to its simplicity, flexibility, and vast ecosystem of packages and tools.

When it comes to deploying Django applications, developers have many options such as bare metal servers, virtual private servers (VPS), platform-as-a-service (PaaS), and containerization. However, managing infrastructure can quickly become a time-sink and distraction from building your core product.

This is why Render has emerged as a leading choice for Django deployment in recent years. Render is a unified cloud platform to build and run all your apps and websites with free TLS certificates, a global CDN, private networks and auto deploys from Git.

Since launching in 2019, Render has become the go-to platform for developers looking to deploy their apps quickly and easily. Over 100,000 developers and businesses use Render to run their web services, APIs, databases, and more.

7. Generous free tier: Render has a free tier that allows you to deploy web services, static sites, databases, and cron jobs at no cost. The free tier is perfect for small projects, hobby apps, and staging environments. Paid plans offer more resources and advanced features at competitive prices.

8. Excellent documentation and support: Render provides extensive documentation, tutorials, and guides to help you get started and troubleshoot issues. Their support team is also responsive and helpful if you run into any problems.

Step-by-Step: Deploying a Django App on Render

Now that we understand the benefits of using Render for Django deployment, let‘s walk through the process step-by-step with a real example.

We‘ll be deploying a basic Django app that allows users to create and view blog posts. The app consists of a PostgreSQL database, a Django backend, and a web frontend.

Prerequisites

Before we begin, make sure you have the following:

• A Render account (sign up for free at https://render.com)
• A Django app in a Git repository (GitHub, GitLab, or Bitbucket)
• Python and pip installed on your local machine
• A PostgreSQL database (we‘ll create one on Render)

Step 1: Create a Django Project

If you don‘t have an existing Django app, let‘s create a new project:

mkdir django-render-blog && cd django-render-blog
python -m venv env
source env/bin/activate  # Linux/Mac
env\Scripts\activate  # Windows
pip install django
django-admin startproject mysite .
python manage.py startapp blog

This creates a new Django project called "mysite" with a "blog" app inside. Let‘s define a simple Blog model in blog/models.py:

from django.db import models

class Blog(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title

And register the model in blog/admin.py to access it from Django admin:

from django.contrib import admin
from .models import Blog

admin.site.register(Blog)

Update mysite/settings.py to include the blog app in INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    ‘blog‘,
]

Finally, let‘s run migrations to set up the initial database schema:

python manage.py makemigrations blog
python manage.py migrate
python manage.py createsuperuser  # create an admin user

Our basic Django app is now ready. You can run it locally with:

python manage.py runserver

Visit http://localhost:8000 to view the app and http://localhost:8000/admin to access the Django admin.

Step 2: Set Up a PostgreSQL Database on Render

Render offers fully managed PostgreSQL databases with one-click setup. Let‘s create one for our Django app.

In your Render dashboard, click "New +" and select "PostgreSQL". Give your database a name, select the free plan, and click "Create Database".

Once the database is created, take note of the "Internal Database URL". We‘ll use this to configure our Django app‘s database settings.

Step 3: Configure Django Settings for Render

To deploy our Django app on Render, we need to make a few changes to the project‘s settings and configuration.

First, install the dj-database-url package which allows us to use Render‘s database URL:

pip install dj-database-url

Update the DATABASES setting in mysite/settings.py to use dj-database-url:

import dj_database_url

DATABASES = {
    ‘default‘: dj_database_url.config(
        default=os.environ.get(‘DATABASE_URL‘)
    )
}

This tells Django to read the database connection URL from the DATABASE_URL environment variable, which we‘ll set up on Render.

Next, let‘s set up a requirements.txt file to specify our app‘s Python dependencies:

pip freeze > requirements.txt

Commit this file to your Git repository so Render can install the necessary packages during deployment.

We also need to create a render.yaml file to tell Render how to build and run our Django app:

services:
  - type: web
    name: django-blog
    env: python
    buildCommand: "./build.sh"
    startCommand: "gunicorn mysite.wsgi:application"
    envVars:
      - key: DATABASE_URL
        fromDatabase:
          name: django-blog-db
          property: connectionString
      - key: SECRET_KEY
        generateValue: true

databases:
  - name: django-blog-db
    plan: free

This file instructs Render to:

1. Create a web service named django-blog using Python
2. Run the build.sh script to build the app (more on this in a bit)
3. Start the app with Gunicorn server
4. Set the DATABASE_URL and SECRET_KEY environment variables
5. Create a PostgreSQL database named django-blog-db on the free plan

Finally, we need to create the build.sh script referenced in render.yaml:

#!/usr/bin/env bash

# Install Python dependencies
pip install -r requirements.txt

# Run database migrations
python manage.py migrate

# Collect static files
python manage.py collectstatic --noinput

Make sure to make this script executable:

chmod a+x build.sh

Add and commit all these changes to your Git repository.

Step 4: Deploy to Render

We‘re ready to deploy our Django app! In your Render dashboard, click "New +" and select "Web Service". Connect your Git repository and choose the branch you want to deploy.

Render will automatically detect the render.yaml file and use it to build and configure your app. Give your service a name, select the free plan, and click "Create Web Service".

Render will now build your app using the build.sh script, set up the PostgreSQL database, and start the Gunicorn server. You can watch the build log to monitor the process.

Once the build completes successfully, your Django app will be live at the auto-generated URL! 🚀

Click on the service URL to view your app in action. You can also find your app‘s URL under the "Domains" section.

To access the Django admin, append /admin to the URL and log in with the superuser credentials you created earlier.

Congratulations, your Django app is now deployed on Render! 🎉

Closing Thoughts

Deploying a Django app doesn‘t have to be complicated or time-consuming. With Render‘s fully-managed cloud platform, you can go from code to production in minutes with just a few clicks.

By following the steps outlined in this guide, you can easily deploy your Django apps to Render and take advantage of its many features like automatic scaling, continuous deployment, managed databases, and more.

But deployment is just the beginning. To ensure your Django app‘s long-term success, you should also implement best practices like:

• Writing tests and running them automatically with each deployment
• Monitoring your app‘s performance and errors with tools like Sentry or New Relic
• Implementing security measures like HTTPS, CSRF protection, and user authentication
• Regularly backing up your database and code repository
• Optimizing your app‘s speed and resource usage
• Keeping your dependencies and packages up-to-date

Render can help with many of these tasks, but it‘s ultimately up to you as the developer to follow good architecture and coding practices.
