This integration guide demonstrates the recommended way to incorporate ZITADEL into your Django Python application.
It explains how to enable user login in your application and how to incorporate the ZITADEL users into the existing AuthenticationBackend.

By the end of this guide, your application will have login functionality with basic role mapping, admin console and polls as described in the Django guide.

This documentation references our [example](https://github.com/zitadel/example-django-python-oidc) on GitHub.

## ZITADEL setup

Before we can start building our application, we have to do a few setup steps in ZITADEL Management Console.

### Project roles

The Example expects [user roles](/guides/integrate/retrieve-user-roles) to be returned after login.
This example expects 3 different roles:
- `admin`: superuser with permissions to use the admin console
- `staff`: user with permissions to see results of the polls
- `user`: normal user with permission to vote on the existing polls

In your project settings make sure the "Assert Roles On Authentication" is enabled.

![Project settings in management console](../../../public/img/django/project-settings.png)

In the project Role tab, add 3 special roles:

- `admin`
- `staff`
- `user`

If none of the roles is provided as a user, the user in Django will not be created.

![Project roles in management console](../../../public/img/django/project-roles.png)

Finally, we can assign the roles to users in the project's `Role Assignments` tab.

![Project role assignments in management console](../../../public/img/django/project-authorizations.png)

### Set up application and obtain secrets

Next you will need to provide some information about your app.

In your Project, add a new application at the top of the page.
Select Web application type and continue.
We use [Authorization Code](/apis/openidoauth/grant-types#authorization-code) for our Django application.

![Create app in management console](../../../public/img/django/app-create.png)

Select `CODE` in the next step. This makes sure you still get a secret. Note that the secret never gets exposed on the browser and is therefore kept in a confidential environment. Safe the generated secret for later use.

![Configure app authentication method in management console](../../../public/img/django/app-auth-method.png)

With the Redirect URIs field, you tell ZITADEL where it is allowed to redirect users to after authentication. For development, you can set dev mode to `true` to enable insecure HTTP and redirect to a `localhost` URI.

For the example application we are writing use:

- `http://localhost:8000/oidc/callback/` as Redirect URI
- `http://localhost:8000/oidc/logout/` as post-logout URI.

![Configure app redirects management console](../../../public/img/django/app-redirects.png)

After the final step you are presented with a client ID and secret.
Copy and paste them to a safe location for later use by the application.
The secret will not be displayed again, but you can regenerate one if you loose it.

## Setup new Django application

### Setup Python

<SetupPython components={props.components} />

### Install dependencies

For this example we need the following dependencies:
- `django`: to create an API with django
- `python-dotenv`: to use environment variables in the settings
- `mozilla-django-oidc`: client-side OIDC functionality

For the dependencies we need a requirements.txt-file with the following content:

```python reference
https://github.com/zitadel/example-python-django-oidc/blob/main/requirements.txt
```

Then install all dependencies with:
```bash
python -m pip install -U requirements.txt
```

The used base is the "Writing your first Django app" from the Django documentation under [https://docs.djangoproject.com/en/5.0/intro/](https://docs.djangoproject.com/en/5.0/intro/),
which has documented additional parts in to use [mozilla-django-oidc](https://github.com/mozilla/mozilla-django-oidc) to integrate ZITADEL as AuthenticationBackend.

Skip this step if you are connecting ZITADEL to an existing application.
</Callout>

## Define the Django app

### Create the settings.py to include mozilla-django-oidc

To use the mozilla-django-oidc as AuthenticationBackend, there are several things to add to the settings.py, as described in the [documentation "Add settings to settings.py"](https://mozilla-django-oidc.readthedocs.io/en/stable/installation.html#add-settings-to-settings-py):

Add INSTALLED_APPS:

```python
INSTALLED_APPS = [
    ...
    "mozilla_django_oidc",  # Load after auth
    ...
]
```

Add MIDDLEWARE:

```python
MIDDLEWARE = [
    #...
    "mozilla_django_oidc.middleware.SessionRefresh",
]
```

Add AUTHENTICATION_BACKENDS:

```python
AUTHENTICATION_BACKENDS = (
    "mysite.backend.PermissionBackend",
)
```

Add settings:

```python reference
https://github.com/zitadel/example-python-django-oidc/blob/main/mysite/settings.py#L130-L174
```

and create a ".env"-file in the root folder with the settings:

```bash
ZITADEL_PROJECT = "ID of the project you created the application in ZITADEL"
OIDC_RP_CLIENT_ID = "ClientID provided by the created application in ZITADEL"
OIDC_RP_CLIENT_SECRET = "ClientSecret provided by the created application in ZITADEL"
OIDC_OP_BASE_URL = "Base URL to the ZITADEL instance"
```

which should then look something like this:

```bash
ZITADEL_PROJECT = "249703732336418457"
OIDC_RP_CLIENT_ID = "249703852243222581@python"
OIDC_RP_CLIENT_SECRET = "Zy3OOHaMBTj2sfamW77Vak5BeQ3nEpOf7suPKTnJKaScMh0lPJqUeDOZmgL3bds0"
OIDC_OP_BASE_URL = "https://example.zitadel.cloud"
```

### AuthenticationBackend definition

To create and update the users regarding the roles given in the authentications in ZITADEL a Subclass of OIDCAuthenticationBackend has to be created:

```python reference
https://github.com/zitadel/example-python-django-oidc/blob/main/mysite/backend.py
```

Which handles the users differently depending on if there are roles associated to:
- `admin` -> superuser
- `staff` -> staff
- `user` -> user
- `no role` -> no user gets created

### URLs

To handle the callback and logout the urls have to be added to the urls.py:
```python
urlpatterns = [
    #...
    path("oidc/", include("mozilla_django_oidc.urls")),
]
```

So it should like something like this:
```python reference
https://github.com/zitadel/example-python-django-oidc/blob/main/mysite/urls.py#L21-L28
```

## Configure and run the application

<Callout type="warn">
Never store and commit secrets in the ".env" or settings.py file
</Callout>

### Authentication and authorization

To check the authentication and authorization, the views in the polls application are extended with decorators:

```python reference
https://github.com/zitadel/example-python-django-oidc/blob/main/mysite/views.py
```

- `@method_decorator(login_required, name="dispatch")`: means that the user has to be logged in Django, which only happens if you have one of the 3 roles("admin", "staff" or "user")
- `@method_decorator(staff_member_required, name="dispatch")`: means you have to have at least a staff user ("admin" or "staff")
- `/admin/`: all admin sides are only accessible if you have a superuser with the role "admin"

<Callout>
Additional permission checks could be done with "permission_required" from "django.contrib.auth.decorators" also described in the [Django documentation](https://docs.djangoproject.com/en/5.0/topics/auth/customizing/#custom-permissions).
</Callout>

### DB

Create and run migrations:

```bash
python manage.py migrate
```

### Run

You can use a local Django server to test the application.

```bash
python manage.py runserver
```

Visit http://localhost:8000/polls or http://localhost:8000/admin and click around.

## Completion

Congratulations! You have successfully integrated your Python Django application with ZITADEL!

If you get stuck, consider checking out our [example](https://github.com/zitadel/example-python-django-oidc) application. This application includes all the functionalities mentioned in this quick-start. You can start by cloning the repository and defining the settings in the settings.py. If you face issues, contact us or raise an issue on [GitHub](https://github.com/zitadel/example-python-django-oidc/issues).

### What's next?

Now that you have enabled authentication, it's time for you to add more authorizations to your application using ZITADEL APIs. To do this, you can refer to the [docs](/apis/introduction) or check out the ZITADEL Management Console code on [GitHub](https://github.com/zitadel/zitadel) which uses gRPC and OpenAPI to access data.
