Overview

Policy::Binding

Represents a Cloud IAM Binding for BigQuery resources within the context of a Google::Cloud::Bigquery::Policy.

A binding binds one or more members to a single role. Member strings can describe user accounts, service accounts, Google groups, and domains. A role is a named list of permissions; each role can be an IAM predefined role or a user-created custom role.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
table = dataset.table "my_table"

policy = table.policy
binding_owner = policy.bindings.find { |b| b.role == "roles/owner" }

binding_owner.role #=> "roles/owner"
binding_owner.members #=> ["user:owner@example.com"]

binding_owner.frozen? #=> true
binding_owner.members.frozen? #=> true

Update mutable bindings.

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
table = dataset.table "my_table"

table.update_policy do |p|
  binding_owner = p.bindings.find { |b| b.role == "roles/owner" }
  binding_owner.members.delete_if { |m| m.include? "@example.com" }
end
