Django Google Drive Storage¶
Please take note that with this implementation you could not save or load data from a user’s Drive. You can use only a Drive dedicated to a Google Project. This means that:
- this storage interacts with Google Drive as a Google Project, not a Google User.
- your project can use Google Drive only through Google Drive SDK. Because no user is associated with this Drive, you cannot use Google Drive User Interface.
- this storage authenticates with Google using public private keys. See prerequisites for how to obtain it.
Having stated that, with this storage you gain a 15GB space hosted on Google Server where you are able to store data using Django models.
To use this storage, you have to:
This storage is hosted on PyPI. It can be easily installed through pip:
pip install django-googledrive-storage
Once installed, there are a few steps to configure the storage:
- add the module gdstorage to your installed apps in your settings.py file:
INSTALLED_APPS = ( ..., 'django.contrib.staticfiles', 'gdstorage' )
- create a section in your setting.py that contains the configuration for this storage:
# # Google Drive Storage Settings # GOOGLE_DRIVE_STORAGE_KEY = '<your private key as a string>' GOOGLE_DRIVE_STORAGE_SERVICE_EMAIL = '<your service mail>'
The GOOGLE_DRIVE_STORAGE_SERVICE_EMAIL should be the email Google assigned to your project, while the GOOGLE_DRIVE_STORAGE_KEY must be the private key as a string obtained by Google.
Since Google will provide you an encrypted p12 file, to obtain the private key you can use the following command:
openssl pkcs12 -in <p12_file> -out <key_file> -nocerts -nodes
You also have to provide the password that Google shows you when the p12 certificate has been created .
Django Google Drive Storage is using Django Appconf to handle settings, so you can setup GOOGLE_DRIVE_STORAGE_KEY as an environment variable outside the Django app.
This will increase security to your environment.

- instantiate the storage on you models.py file before using into the models:
from gdstorage.storage import GoogleDriveStorage # Define Google Drive Storage gd_storage = GoogleDriveStorage()
Once configured, it can be used as storage space associated with Django:
class Map(models.Model): id = models.AutoField( primary_key=True) map_name = models.CharField(max_length=200) map_data = models.FileField(upload_to='/maps', storage=gd_storage)
