# DRF Firebase Auth
## Requirements
* Python3
* Django
* Django Rest Framework
## Installation
```
$ pip install drf-firebase-auth
```
Add the application to your project's `INSTALLED_APPS` in `settings.py`.
```python
INSTALLED_APPS = [
...
'drf_firebase_auth',
]
```
In your project's `settings.py`, add this to the `REST_FRAMEWORK` configuration. Note that if you want to retain access to the browsable API for locally created users, then you will probably want to keep `rest_framework.authentication.SessionAuthentication` too.
```python
REST_FRAMEWORK = {
...
'DEFAULT_AUTHENTICATION_CLASSES': [
...
'rest_framework.authentication.SessionAuthentication',
'drf_firebase_auth.authentication.FirebaseAuthentication',
]
}
```
The `drf_firebase_auth` application comes with the following settings as default, which can be overridden in your project's `settings.py` file. For convenience in version >= 1, most of these can be conveniently set form environment variables also. Make sure to nest them within `DRF_FIREBASE_AUTH` as below:
```python
DRF_FIREBASE_AUTH = {
# allow anonymous requests without Authorization header set
'ALLOW_ANONYMOUS_REQUESTS': os.getenv('ALLOW_ANONYMOUS_REQUESTS', False),
# path to JSON file with firebase secrets
'FIREBASE_SERVICE_ACCOUNT_KEY':
os.getenv('FIREBASE_SERVICE_ACCOUNT_KEY', ''),
# allow creation of new local user in db
'FIREBASE_CREATE_LOCAL_USER':
os.getenv('FIREBASE_CREATE_LOCAL_USER', True),
# attempt to split firebase user.display_name and set local user
# first_name and last_name
'FIREBASE_ATTEMPT_CREATE_WITH_DISPLAY_NAME':
os.getenv('FIREBASE_ATTEMPT_CREATE_WITH_DISPLAY_NAME', True),
# commonly JWT or Bearer (e.g. JWT <token>)
'FIREBASE_AUTH_HEADER_PREFIX':
os.getenv('FIREBASE_AUTH_HEADER_PREFIX', 'JWT'),
# verify that JWT has not been revoked
'FIREBASE_CHECK_JWT_REVOKED':
os.getenv('FIREBASE_CHECK_JWT_REVOKED', True),
# require that firebase user.email_verified is True
'FIREBASE_AUTH_EMAIL_VERIFICATION':
os.getenv('FIREBASE_AUTH_EMAIL_VERIFICATION', False),
# function should accept firebase_admin.auth.UserRecord as argument
# and return str
'FIREBASE_USERNAME_MAPPING_FUNC': map_firebase_uid_to_username
}
```
You can get away with leaving all the settings as default except for `FIREBASE_SERVICE_ACCOUNT_KEY`, which is obviously required.
NOTE: `FIREBASE_USERNAME_MAPPING_FUNC` will replace behaviour in version < 1 as default (formerly provided by logic in `map_firebase_to_username_legacy`, described below). One can simply switch out this function.
`drf_firebase_auth.utils` contains functions for mapping firebase user info to the Django username field (new in version >= 1). Any custom function can be supplied here, as long as it accepts a `firebase_admin.auth.UserRecord` argument. The supplied functions are common use-cases:
```python
def map_firebase_to_username_legacy(firebase_user: auth.UserRecord) -> str:
try:
username = '_'.join(
firebase_user.display_name.split(' ')
if firebase_user.display_name
else str(uuid.uuid4())
)
return username if len(username) <= 30 else username[:30]
except Exception as e:
raise Exception(e)
def map_firebase_display_name_to_username(
firebase_user: auth.UserRecord
) -> str:
try:
return '_'.join(firebase_user.display_name.split(' '))
except Exception as e:
raise Exception(e)
def map_firebase_uid_to_username(
firebase_user: auth.UserRecord
) -> str:
try:
return firebase_user.uid
except Exception as e:
raise Exception(e)
def map_firebase_email_to_username(
firebase_user: auth.UserRecord
) -> str:
try:
return get_firebase_user_email(firebase_user)
except Exception as e:
raise Exception(e)
def map_uuid_to_username(
_: auth.UserRecord
) -> str:
try:
return str(uuid.uuid4())
except Exception as e:
raise Exception(e)
```
Now that you have configured the application, run the migrations so that the Firebase data can be stored.
```
$ ./manage.py migrate drf_firebase_auth
```
All you need to do now is have your client code handle the Firebase popup/redirect authentication flow, retrieve the idToken from the currentUser (Firebase explains this flow well in their docs: `https://firebase.google.com/docs/auth/admin/verify-id-tokens`), and then use the idToken for the user in an `Authorization` header in requests to your API.
```
JWT <token>
```
Voila!

* Trello board created! Please follow this link if you wish to collabrate in the future direction of this package: https://trello.com/invite/b/lkAsvStS/af54d9a94359c042f3bd9afb47f82eab/drf-firebase-auth
* Please raise an issue/feature and name your branch 'feature-n' or 'issue-n', where 'n' is the issue number.
* If you test this code with a Python version not listed above and all is well, please fork and update the README to include the Python version you used :)
* I almost always setup Django with a custom user class inheriting from AbstractUser, where I switch the USERNAME_FIELD to be 'email'. This backend is setup to assign a username still anyway, but if there are any issues, please raise them and/or make a pull request to help the community!
