Deploy a Django App on Render

This guide walks through deploying a Django Python app on Render. You can use your existing Django project or create one from scratch.

If you're new to Django, we recommend first reading the official guide to Writing your first Django project.

Updating an existing Django project

To prepare an existing Django project for production on Render, we'll make a couple adjustments to its configuration:

We'll update your project to use a Render PostgreSQL database instead of a SQLite database.
We'll configure the WhiteNoise package to serve your project's static files.
We'll define a build script to run with each deploy.

Use a Render PostgreSQL database

As part of deploying your project, we'll also deploy a Render PostgreSQL database to serve as its backing datastore. To enable this, let's add a couple of packages to your project:

Package	Description
psycopg2	This is the most popular Python adapter for communicating with a PostgreSQL database.
DJ-Database-URL	This enables you to specify your database details via the `DATABASE_URL` environment variable (you'll obtain your database's URL from the Render Dashboard).

Run the following commands to install these packages:

bash

$ pip install psycopg2-binary

$ pip install dj-database-url

# Add these dependencies to your requirements.txt file:
$ pip freeze > requirements.txt

Open settings.py in your project's main directory (e.g., mysite/settings.py).

Make the following modifications:

python

# Import dj-database-url at the beginning of the file.
import dj_database_url

python

# Replace the SQLite DATABASES configuration with PostgreSQL:
DATABASES = {
    'default': dj_database_url.config(
        # Replace this value with your local database's connection string.
        default='postgresql://postgres:postgres@localhost:5432/mysite',
        conn_max_age=600
    )
}

Set up static file serving

Django provides a dedicated module for collecting your project's static files (HTML, CSS, JavaScript, images, and so on) into a single place for serving in production. This module supports moving files from one place to another, relying on the end web server (such as Render's default web server, or a tool like NGINX) to serve them to end users.

In this step, we'll set up WhiteNoise to serve these static assets from Render's web server.

The following instructions summarize the setup described in the WhiteNoise documentation.

Add WhiteNoise as a dependency (adding Brotli support is optional, but recommended):
bash
```
$ pip install 'whitenoise[brotli]'
$ pip freeze > requirements.txt
```
Open settings.py in your project's main directory (e.g., mysite/settings.py).

Add the following to the MIDDLEWARE list, immediately after SecurityMiddleware:
python
```
MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware', 
    ...
]
```

Still in settings.py, find the section where static files are configured.

Make the following modifications:

python

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/5.0/howto/static-files/

# This setting informs Django of the URI path from which your static files will be served to users
# Here, they well be accessible at your-domain.onrender.com/static/... or yourcustomdomain.com/static/...
STATIC_URL = '/static/'

# This production code might break development mode, so we check whether we're in DEBUG mode
if not DEBUG:
    # Tell Django to copy static assets into a path called `staticfiles` (this is specific to Render)
    STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

    # Enable the WhiteNoise storage backend, which compresses static files to reduce disk use
    # and renames the files with unique names for each version to support long-term caching
    STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

All set! We're ready to serve static content from our Django project on Render.

Create a build script

Whenever you deploy a new version of your project, Render runs a build command to prepare it for production. Let's create a script for Render to run as this build command.

Create a new file called build.sh in your project's root directory and paste in the following:

bash

#!/usr/bin/env bash
# Exit on error
set -o errexit

# Modify this line as needed for your package manager (pip, poetry, etc.)
pip install -r requirements.txt

# Convert static asset files
python manage.py collectstatic --no-input

# Apply any outstanding database migrations
python manage.py migrate

Make sure the script is executable before adding it to version control:

shell

$ chmod a+x build.sh

We'll configure Render to run this build script whenever a new deploy is initiated.

We'll run your project with Uvicorn and Gunicorn. Add these dependencies to your project:
shell
```
$ pip install gunicorn uvicorn
$ pip freeze > requirements.txt
```
Try running your project locally!

Replace mysite in the command below with your project's name.
shell
```
$ python -m gunicorn mysite.asgi:application -k uvicorn.workers.UvicornWorker
```
Visit http://localhost:8000 in your browser to verify that your project is up and running.

Commit all changes and push them to your repository. Your project is ready to deploy to Render!

Deploying to Render

There are two ways to deploy your Django project on Render, either by declaring your services within your repository using a render.yaml file or by manually setting up your services using the dashboard. In this tutorial, we will walk through both options.

Use `render.yaml` for deploys

Create a file named render.yaml in the root of your project. This file will define your Django web service, along with the database it connects to. Don't forget to commit and push it to your repository.

The gunicorn command in the highlighted line below assumes your Django project is named mysite. Update it for your project as needed.

yaml

databases:
  - name: mysitedb
    plan: free
    databaseName: mysite
    user: mysite

services:
  - type: web
    plan: free
    name: mysite
    runtime: python
    buildCommand: './build.sh'
    startCommand: 'python -m gunicorn mysite.asgi:application -k uvicorn.workers.UvicornWorker' 
    envVars:
      - key: DATABASE_URL
        fromDatabase:
          name: mysitedb
          property: connectionString
      - key: SECRET_KEY
        generateValue: true
      - key: WEB_CONCURRENCY
        value: 4

In the Render Dashboard, go to the Blueprints page and click New Blueprint Instance.
Select the repository that contains your blueprint and click Connect.
Give your blueprint project a name and click Apply.

That's it! Your project will be live at its .onrender.com URL as soon as the build finishes.

Manual deployment

Create a new PostgreSQL database on Render. Copy its internal database URL for now—you'll need it later.
Create a new web service on Render, pointing it to your project's GitHub/GitLab/Bitbucket repository (give Render permission to access it if you haven't already).
Select Python 3 for the Language and set the following properties (replace mysite with your project's name):

Property Value
Build Command ./build.sh
Start Command python -m gunicorn mysite.asgi:application -k uvicorn.workers.UvicornWorker
Add the following environment variables under Advanced:

Key Value
DATABASE_URL The internal database URL for the database you created above
SECRET_KEY Click Generate to get a secure random value
WEB_CONCURRENCY 4

Property	Value
Build Command	`./build.sh`
Start Command	`python -m gunicorn mysite.asgi:application -k uvicorn.workers.UvicornWorker`

Key	Value
`DATABASE_URL`	The internal database URL for the database you created above
`SECRET_KEY`	Click Generate to get a secure random value
`WEB_CONCURRENCY`	`4`

That's it! Save your web service to deploy your Django application on Render. It will be live on your .onrender.com URL as soon as the build finishes.

Create a Django admin account

Once your application is live, create a new Django admin account by running the following command in the Render Shell:

shell

$ python manage.py createsuperuser

See Setting your Python Version if you need to customize the version of Python used for your app.

Creating a new Django project

This section walks through setting up a Django project and adding an application with a simple view.

The finished code for this example is available on GitHub, and you can view the project running here.

This tutorial starts with a bare-bones installation and explains all required code modifications. Feel free to adapt it with custom configuration as needed.

Installation & setup

First, we'll set up our local development environment and create a basic project structure.

We'll call our project mysite. You can use a different name, but make sure to modify all commands that use mysite below to match the name you choose.

1. Create your directory and virtual environment

Run the following commands in your terminal (see comments for descriptions):

shell

# Create a new project directory and cd into it
$ mkdir mysite
$ cd mysite

# Create a virtual environment using Python's venv package
$ python -m venv venv

# Activate the virtual environment to start installing other packages
$ source venv/bin/activate

2. Install Django and create your project

Run the following from your project's root directory to install Django:

shell

# This installs Django 5.0.1 (feel free to modify the version as needed)
$ pip install django==5.0.1
$ pip freeze > requirements.txt

Then run the following to initialize your mysite Django project:

shell

$ django-admin startproject mysite .

You'll end up with the following directory structure:

.
├── manage.py
├── mysite
│   ├── __init__.py
│   ├── asgi.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── venv (you can ignore everything in here for now)
    ├──

You now have a fully functional scaffold for your new Django project! To verify, you can start the development server:

shell

$ python manage.py runserver

Then visit http://localhost:8000 in your browser:

Django Successful Installation

Creating a landing page

Next, we'll add an application to our Django project that serves a simple landing page.

Django projects contain one or more applications, which are wired together to form a complete service. Django provides several built-in applications, such as its admin site.

1. Create a new application

Run the following command from your project's root directory:

shell

$ python manage.py startapp homepage

This creates a directory for a new application named homepage with following contents:

homepage
├── __init__.py
├── admin.py
├── apps.py
├── migrations
│   └── __init__.py
├── models.py
├── tests.py
└── views.py

We need to inform Django about this new homepage application. Open mysite/settings.py and find the the INSTALLED_APPS setting. Add a reference to the HomepageConfig class to the beginning of the list:
python
```
INSTALLED_APPS = [
    'homepage.apps.HomepageConfig', 
    'django.contrib.admin',
    'django.contrib.auth',
    ...
]
```
For more information about the INSTALLED_APPS setting, see the Django settings information page

2. Write your first view

Let's create a simple view in our homepage application that we'll serve from our service's root path. First we'll define the view, then we'll configure its routing.

Create a new file at homepage/templates/homepage/index.html. Paste in the following HTML:

jinja2

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

    <title>Hello Django on Render!</title>

    <link rel="stylesheet"
          href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css"
          integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk"
          crossorigin="anonymous">
</head>
<body>
<main class="container">
    <div class="row text-center justify-content-center">
        <div class="col">
            <h1 class="display-4">Hello World!</h1>
        </div>
    </div>
</main>
</body>
</html>

Nothing fancy

In the file homepage/views.py, add the following Python code for the index method:
python
```
from django.shortcuts import render

# Create your views here.

def index(request): 
    return render(request, 'homepage/index.html', {}) 
```
This method renders the homepage/index.html template we just created.
Create a new file named homepage/urls.py and paste in the following:
python
```
from django.urls import path

from . import views

urlpatterns = [
    path('', views.index, name='index'),
]
```
This file tells Django that you want to serve the index view from your service's root URL.

Configure the Django project to point to the homepage application's urls module. Open mysite/urls.py and update the from django.urls import path line to add the include module, and then include the homepage application's URLs module to our urlpatterns, like so:

python

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('homepage.urls')),
]

Your folder structure should now look like this:

render
├── __init__.py
├── admin.py
├── apps.py
├── migrations
│   └── __init__.py
├── models.py
├── templates
│   └── render
│       └── index.html
├── tests.py
├── urls.py
└── views.py

Add a static file to your application. Download this image and save it as homepage/static/homepage/render-banner.png:

Return to your index.html template. Load the static module and reference the downloaded image in a new <header></header> block:

jinja2

{% load static %}

<!doctype html>
<html lang="en">
...
<body>
<header class="container mt-4 mb-4">
    <a href="https://render.com">
        <img src="{% static "homepage/render-banner.png" %}" alt="Homepage banner" class="mw-100">
    </a>
</header>
...
</body>
</html>

You can now verify your app is working with the following command:
bash
```
python manage.py runserver
```
Reload your browser tab at localhost:8000 to make sure the banner and text are showing properly.

Adding basic security

You should ensure that any production-level application is properly secured and configured. The Django documentation provides a useful deployment checklist, which we'll follow in this step.

Open mysite/settings.py and find the declaration of the SECRET_KEY setting. We don't want to store production secrets in source code, so we'll fetch this value from an environment variable that we'll create later:
python
```
# Don't forget to import os at the beginning of the file
import os
```
python
```
# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.environ.get('SECRET_KEY', default='your secret key')
```
Find the declaration of the DEBUG setting. This setting should never be set to True in a production environment. You can detect that you're running on Render by checking for the presence of the RENDER environment variable in the application environment:
python
```
# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = 'RENDER' not in os.environ
```
When DEBUG is False, Django requires a suitable value for ALLOWED_HOSTS. You can get the name of your web service host from the RENDER_EXTERNAL_HOSTNAME environment variable, which is automatically set by Render.
python
```
# https://docs.djangoproject.com/en/3.0/ref/settings/#allowed-hosts
ALLOWED_HOSTS = []

RENDER_EXTERNAL_HOSTNAME = os.environ.get('RENDER_EXTERNAL_HOSTNAME')
if RENDER_EXTERNAL_HOSTNAME:
    ALLOWED_HOSTS.append(RENDER_EXTERNAL_HOSTNAME)
```
If you add a custom domain to your service, don't forget to add it to this list.

Adding PostgreSQL support

We will add the DJ-Database-URL package, which allows us to specify databases in Django using connection strings. Render provides database connection strings in the Render Dashboard, which you will provide to your web service via the DATABASE_URL environment variable. We will also need to add psycopg2 to the project.

Run the following command to add the necessary dependencies to your project:
bash
```
$ pip install dj-database-url psycopg2-binary
$ pip freeze > requirements.txt
```

In mysite/settings.py, find the declaration of the DATABASES setting and modify it to look like the following:

python

# Import the dj-database-url package at the beginning of the file
import dj_database_url

python

# Database documentation https://docs.djangoproject.com/en/5.0/ref/settings/#databases

DATABASES = {
    'default': dj_database_url.config(
        # Replace this value with your local database's connection string.
        default='postgresql://postgres:postgres@localhost:5432/mysite',
        conn_max_age=600
    )
}

This connection string assumes that you have PostgreSQL running on localhost, on port 5432, with a database named mysite and a user named postgres with the password postgres.

Apply our database migrations. A "migration" is a step-by-step process of creating database tables and fields for our Django project. We will use the migrate command to run the migrations:

shell

$ python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
