A simple package for adding Shopify authentication to Django apps.
Django Shopify Auth
This Django package makes it easy to integrate Shopify authentication into your Django app. It shares some similarities with the shopify_django_app project, but with a couple of key differences:
It provides a custom Django Authentication scheme based on
RemoteUserBackend, meaning shops will be authenticated as "users" of your Django app. This makes it easier to use common Django patterns and libraries (such as accessing the currently authenticated store as
It persists users' Shopify access tokens in the database, rather than in the Session, meaning your app will be able to make API calls on behalf of a user when they're not logged in.
It supports the authentication flow for new-style "Embedded SDK" Shopify apps.
This project provides one package,
A demonstration Django project using this package is available here.
If you'd like a detailed breakdown of how to set up an app from scratch using this package, I've recorded a a short
series of five minute screencasts showing how to get
an app using
django-shopify-auth up and running in under 15 minutes.
The package author (@gavinballard) is currently in "non-active maintenance" mode. I am happy to review and merge pull requests that provide a clear description of the problem they solve and provide a thorough test to avoid any regressions, but as I don't use Django in my day-to-day Shopify development any more (the last version I used with much regularity was Django 1.9) I am not actively working on the code.
If you're using this package on a regular basis and feel you'd be a good fit to take over active development, please contact me.
Tests are run against Django versions defined in
.travis.yml. This package may work for
other Django versions but it's not guaranteed.
As with the original
shopify_django_app package, you'll need a Shopify partner account
and to have created an app in order to get an API key and secret.
Package Installation and Setup
There are a few moving parts to set up, but hopefully the following instructions will make things straightforward.
We're assuming in this setup that you're using a standard Django project layout (the sort that's created with the
django-admin.py startproject command). We're also assuming that our project is called
auth_demo and that the primary
Django app inside our project is going to be called
If you ever get lost or aren't really sure what to do, you can refer to the demo app.
1. Install package
Installation is super easy via
> pip install django-shopify-auth
Once you have the package installed, add
shopify_auth to your
2. Add custom user model
shopify_auth makes use of Django's authentication system, it provides a custom authentication backend
shopify_auth.backends.ShopUserBackend) which allows authentication through Shopify's OAuth flow.
This backend requires that the user model for your app (specified by
AUTH_USER_MODEL in your
shopify_auth.models.AbstractShopUser. To do this, just add something like this to the
models.py for your
# auth_demo/auth_app/models.py from shopify_auth.models import AbstractShopUser class AuthAppShopUser(AbstractShopUser): pass
Then make sure that you have the following line or similar in
AUTH_USER_MODEL = 'auth_app.AuthAppShopUser'
3. Configure settings
In addition to setting
AUTH_USER_MODEL, there are a few more required additions to
# Configure Shopify Application settings SHOPIFY_APP_NAME = 'Your App Name' SHOPIFY_APP_API_KEY = os.environ.get('SHOPIFY_APP_API_KEY') SHOPIFY_APP_API_SECRET = os.environ.get('SHOPIFY_APP_API_SECRET') SHOPIFY_APP_API_SCOPE = ['read_products', 'read_orders'] # Find API version to pin at https://help.shopify.com/en/api/versioning SHOPIFY_APP_API_VERSION = "0000-00" SHOPIFY_APP_IS_EMBEDDED = True SHOPIFY_APP_DEV_MODE = False # Use the Shopify Auth authentication backend as the sole authentication backend. AUTHENTICATION_BACKENDS = ( 'shopify_auth.backends.ShopUserBackend', ) # Add the Shopify Auth template context processor to the list of processors. # Note that this assumes you've defined TEMPLATE_CONTEXT_PROCESSORS earlier in your settings. TEMPLATE_CONTEXT_PROCESSORS += ( 'shopify_auth.context_processors.shopify_auth', ) # Use the Shopify Auth user model. AUTH_USER_MODEL = 'auth_app.AuthAppShopUser' # Set the login redirect URL to the "home" page for your app (where to go after logging on). LOGIN_REDIRECT_URL = '/' # Set secure proxy header to allow proper detection of secure URLs behind a proxy. # This ensures that correct 'https' URLs are generated when our Django app is running behind a proxy like nginx, or is # being tunneled (by ngrok, for example). SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') # For Django>=2.1, if you are using ngrok or other tools for tunnelling/proxying when developing, # we must explicitly allow cookies from different sites or the auth redirection after the login will # result in an infinite loop (session cannot be read from cookies) SESSION_COOKIE_SAMESITE = False
Note that in the example above, the application API key and API secret are pulled from environment settings, which is a best practice for Django apps that helps avoid the accidental check-in of sensitive information to source files.
True if your app has been configured as an Embedded app (you choose this option at
<iframe> during the authentication flow as per the Shopify documentation.
False, the normal authentication flow for non-Embedded apps will be used.
True allows you to test your apps locally by skipping the external OAuth phase for
your app. As it means you can log into your app as any store, you should obviously never set this to
Now that all of the settings are configured, you can run
migrate to set up the database for your new user model:
> python manage.py migrate
4. Configure URL mappings
shopify_auth URLs in your project's
# urls.py from django.urls import include, path urlpatterns = [ path('login/', include('shopify_auth.urls')), # ... remaining configuration here ... ]
Earlier versions of Django
# urls.py from django.conf.urls import patterns, include, url urlpatterns = patterns('', url(r'login/', include('shopify_auth.urls')), # ... remaining configuration here ... )
5. Create application views
Now that you've gotten the configuration out of the way, you can start building your application.
All views inside your application should be decorated with
This decorator will check that a user has authenticated through the Shopify OAuth flow.
If they haven't, they'll be redirected to the login screen.
from django.shortcuts import render from shopify_auth.decorators import login_required @login_required def home(request, *args, **kwargs): return render(request, "my_app/home.html")
6. Using the Embedded App SDK
<head> to properly frame your app within the Shopify Admin.
Generally, all pages you'd like embedded in the Shopify Admin should contain something like this in
Recent versions of Django's
django.middleware.clickjacking.XFrameOptionsMiddleware to the
MIDDLEWARE_CLASSES list in
settings.py. This prevents pages being loading in an
<iframe>, meaning your app pages
will not be displayed in the Shopify admin.
To resolve this issue, you should either remove
XFrameOptionsMiddleware from your
MIDDLEWARE_CLASSES, or ensure that
all of your app views make use of the
7. Making Shopify API calls
To make Shopify API calls on behalf of a user, we can use the user's
session property inside a
def view(request, *args, **kwargs): # Get a list of the user's products. with request.user.session: products = shopify.Product.find() # ... remaining view code ...
Behind the scenes, using
with request.user.session sets up a temporary Shopify API session using the OAuth token we
obtained for that specific user during authentication.
All code wrapped within the
with statement is executed in the context of the specified user. You should always wrap
calls to the Shopify API using this pattern.
Partner Application Setup
In addition to getting the package up and running in your local Django project, you'll need to configure your application via the Shopify Partner dashboard. The first part of my brief screencast series walks you through the setup of a Shopify Partner application.
An important omission from the screencast series is that Shopify now requires applications to provide a list of authorized "Redirection URLs" from the partner dashboard for enhanced security (this wasn't a required setting at the time of recording the screencasts).
To avoid getting an OAuth error while customers try to install your application, make sure your application's settings
include the absolute URL to
/login/finalize/ (including the trailing slash) in their whitelisted URLs. For example,
if your application resides at
https://myapp.example.com, then you should include
https://myapp.example.com/login/finalize/ in the "Redirection URL" section of your application settings.
