Class Method Details

.datastore(project_id = nil, credentials = nil, scope: nil, timeout: nil, database_id: nil) ⇒ Google::Cloud::Datastore::Dataset

Creates a new object for connecting to the Datastore service. Each call creates a new connection.

For more information on connecting to Google Cloud see the Authentication Guide.

Examples:

require "google/cloud"

datastore = Google::Cloud.datastore "my-todo-project",
                                    "/path/to/keyfile.json"

task = datastore.entity "Task", "sampleTask" do |t|
  t["type"] = "Personal"
  t["done"] = false
  t["priority"] = 4
  t["description"] = "Learn Cloud Datastore"
end

datastore.save task

Parameters:

  • project_id (String) (defaults to: nil) —

    Identifier for a Datastore project. If not present, the default project for the credentials is used.

  • credentials (String, Hash, Google::Auth::Credentials) (defaults to: nil) —

    The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Google::Cloud::Datastore::Credentials)

  • scope (String, Array<String>) (defaults to: nil) —

    The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

    The default scope is:

    • https://www.googleapis.com/auth/datastore
  • timeout (Integer) (defaults to: nil) —

    Default timeout to use in requests. Optional.

Returns:

Instance Method Details

#datastore(scope: nil, timeout: nil, database_id: nil) ⇒ Google::Cloud::Datastore::Dataset

Creates a new object for connecting to the Datastore service. Each call creates a new connection.

For more information on connecting to Google Cloud see the Authentication Guide.

Examples:

require "google/cloud"

gcloud  = Google::Cloud.new
datastore = gcloud.datastore

task = datastore.entity "Task" do |t|
  t["type"] = "Personal"
  t["done"] = false
  t["priority"] = 4
  t["description"] = "Learn Cloud Datastore"
end

datastore.save task

You shouldn't need to override the default scope, but you can:

require "google/cloud"

gcloud  = Google::Cloud.new
platform_scope = "https://www.googleapis.com/auth/cloud-platform"
datastore = gcloud.datastore scope: platform_scope

Parameters:

  • scope (String, Array<String>) (defaults to: nil) —

    The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

    The default scope is:

    • https://www.googleapis.com/auth/datastore
  • timeout (Integer) (defaults to: nil) —

    Default timeout to use in requests. Optional.
