Use Google Datastore as Cache for Ruby on Rails application.

How to use the plugin:

  config.cache_store = :gcloud_datastore

Enviroment variable GOOGLE_CLOUD_PROJECT required.

Alternately:

  config.cache_store = :gcloud_datastore, {
      project_id: "gcloud-project-slug-name"
  }

Sometimes credential file is needed (for example in local development):

  config.cache_store = :gcloud_datastore, {
      project_id: "gcloud-project-slug-name",
      credential_file_json: "/path/to/credential_file.json"
  }

or set enviroment variable: GOOGLE_APPLICATION_CREDENTIALS

export GOOGLE_APPLICATION_CREDENTIALS /path/to/credential_file.json

Add this line to your application's Gemfile:

gem 'gcloud-datastore-activesupport'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gcloud-datastore-activesupport
