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: casa_org_metrics.rb
    path of file: ./repos/casa/app/models/all_casa_admins
    
    the code of the file until where you have to start completion: module AllCasaAdmins
  class CasaOrgMetrics
    def initialize(casa_org)
      @casa_org = casa_org
    end

    def metrics
      {
        "Number of admins" => @casa_org.casa_admins.count,
        "Number of supervisors" => @casa_org.supervisors.count,
        "Number of active volunteers" => @casa_org.volunteers.active.count,
        "Number of inactive volunteers" => @casa_org.volunteers.inactive.count,
        "Number of active cases" => @
    
    def metrics

        "Number of inactive cases" => @casa_org.casa_cases.inactive.count,
        "Number of all case contacts including inactives" => @casa_org.case_assignments.count,
