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: income_calculator.rb
    path of file: ./repos/vets-api/modules/debts_api/lib/debts_api/v0/fsr_form_transform
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module DebtsApi
  module V0
    module FsrFormTransform
      class IncomeCalculator
        def initialize(form)
          @form = form
  
    
        def name_str(social_security, compensation, education, addl_inc)
          benefit_types = []

          benefit_types.push('Social Security') if social_security
          benefit_types.push('Disability Compensation') if compensation
          benefit_types.push('Education') if education

          vet_addl_names = addl_inc&.pluck('name') || []
          other_inc_names = [*benefit_types, *vet_addl_names]

          other_inc_names&.join(', ') || ''
        end
