You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: clusters_finder.rb
    path of file: ./repos/gitlabhq/app/finders
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

c
    
  def filter_by_scope(clusters)
    case scope.to_sym
    when :all
      clusters
    when :inactive
      clusters.disabled
    when :active
      clusters.enabled
    else
      raise "Invalid scope #{scope}"
    end
