Description:

djangogcloudstorage 0.5.0

Django storage module implementation for Google Cloud Storage using the
google-cloud-storage python module by Google.

Notice: alpha release
Please keep in mind that this version is not yet used in any production application
(as far as I know of) and thus is an alpha release, even though fully tested!
Any kind of feedback is greatly appreciated.

Installation
Install django-gcloud-storage:
pip install django-gcloud-storage
Create a GCS service account JSON keyfile and a bucket for your application.
Check the documentation of Google Cloud Platform for more details:
https://cloud.google.com/iam/docs/creating-managing-service-accounts#creating
https://cloud.google.com/iam/docs/creating-managing-service-account-keys#creating
Update your Django settings and use it like any other Django storage module:
DEFAULT_FILE_STORAGE = 'django_gcloud_storage.DjangoGCloudStorage'

GCS_PROJECT = "django-gcloud-storage"
GCS_BUCKET = "django-gcloud-storage-bucket"
GCS_CREDENTIALS_FILE_PATH = "/path/to/gcs-credentials.json"

Features

Fully tested on Python 3.7 - 3.10, PyPy 3.7-7.3.7 and PyPy 3.8-7.3.7 with
Django 2.2, 3.2 and 4.0
Files are locally downloaded as SpooledTemporaryFile objects to avoid memory
abuse
Changed files will automatically be reuploaded to GCS when closed

Caveats

Files must be fully downloaded to be accessed and fully uploaded when changed
Everytime a file is opened via the storage module, it will be downloaded again
(development) Most tests need access to Google Cloud Storage

Unsigned URLS
The module generates signed urls by default. This requires calls to storage API
which might take some time if you need to return several objects at a time. You
can generate unsigned urls using the following setting:
GCS_USE_UNSIGNED_URLS = True
Keep in mind you might need to set the default object permission to public for
the unsigned urls to work.

Contributing
Contributions are welcome, and they are greatly appreciated! Every
little bit helps, and credit will always be given.

articles, and such.

Pull Request Guidelines
Before you submit a pull request, check that it meets these guidelines:

The pull request should include tests.
The pull request should work for all supported Python and Django versions
(see above). Make sure that the tests pass.

Running Tests
Warning: Most of the tests require a GCS project and will do API requests that
may end up costing you money!
You can run the test suite either in a virtualenv with py.test or with tox - both
require a valid service account JSON keyfile called test-credentials.json in
the project root. The GCS project name will be provided via a command argument.
The tests will create and (hopefully) remove buckets on their own. To be safe,
check if there are any leftover buckets in your GCS project after running the
tests!
source <YOURVIRTUALENV>/bin/activate
(myenv) $ pip install -r requirements-test.txt
(myenv) $ pip install -e .
(myenv) $ py.test --gcs-project-name="project-name"

or

$ tox -- --gcs-project-name="project-name"
