User Management

    +
    The Ruby SDK lets you create users, assign them roles and associated privileges, and remove them from the system.

    User-Management APIs

    Users who have been assigned the Admin role for the cluster are able to create, edit, and remove users. The Ruby SDK provides APIs to support these activities. A high-level summary of the APIs can be found in User-Management, and details of all options in the UserManager API docs.

    Using the UserManager API

    The most common uses of the UserManager API are creating and listing users:

    Creating Users
    user = Management::User.new
    user.username = "testUsername"
    user.password = "testPassword"
    user.display_name = "Constance Lambert"
    user.roles = [
      # Roles required for the reading of data from the bucket
      Management::Role.new do |r|
        r.name = "data_reader"
        r.bucket = "*"
      end,
      Management::Role.new do |r|
        r.name = "query_select"
        r.bucket = "*"
      end,
    
      # Roles required for the writing of data into the bucket
      Management::Role.new do |r|
        r.name = "data_writer"
        r.bucket = "*"
      end,
      Management::Role.new do |r|
        r.name = "query_insert"
        r.bucket = "*"
      end,
      Management::Role.new do |r|
        r.name = "query_delete"
        r.bucket = "*"
      end,
    
      # Role required for the creation of indexes on the bucket
      Management::Role.new do |r|
        r.name = "query_manage_index"
        r.bucket = "*"
      end,
    ]
    cluster.users.upsert_user(user)
    Listing Users
    list_of_users = cluster.users.get_all_users
    list_of_users.each do |current_user|
      puts "User's display name is: #{current_user.display_name}"
      current_roles = current_user.roles
      current_roles.each do |role|
        puts "    User has the role: #{role.name}, applicable to bucket #{role.bucket}"
      end
    end

    Using a user created in the SDK to access data:

    bucket_name = "travel-sample"
    options = Cluster::ClusterOptions.new
    options.authenticate("testUsername", "testPassword")
    user_cluster = Cluster.connect("couchbase://localhost", options)
    user_bucket = user_cluster.bucket(bucket_name)
    user_collection = user_bucket.default_collection
    
    options = Management::QueryIndexManager::CreatePrimaryIndexOptions.new
    options.ignore_if_exists = true
    cluster.query_indexes.create_primary_index(bucket_name, options)
    
    p returned_airline10_doc: user_collection.get("airline_10").content
    
    airline11_object = {
      "callsign" => "MILE-AIR",
      "iata" => "Q5",
      "icao" => "MLA",
      "id" => 11,
      "name" => "40-Mile Air",
      "type" => "airline",
    }
    user_collection.upsert("airline_11", airline11_object)
    
    p returned_airline11_doc: user_collection.get("airline_11").content
    
    result = user_cluster.query("SELECT * from `#{bucket_name}` LIMIT 5")
    result.rows.each_with_index do |row, idx|
      puts "#{idx}: #{row}"
    end
    
    user_cluster.disconnect

    The SDK also contains management APIs for dealing with Cluster resources.
