Simple to use :

• Read csv using headers to name symbols
• Parse table like each row is a hash where each column header is a symbol's name.
• do whatever you want with value.

Example :

require 'smarter_csv'                                                               

# Class CodePostaux                                                                 
class CodePostaux                                                                   
  attr_accessor :csv_file_path, :cp_hash                                            

  def initialize(csv_file_path)                                                     
    @csv_file_path = csv_file_path                                                  
    @cp_hash = Hash.new                                                             
  end                                                                               

  def read_csv                                                                      
    SmarterCSV.process(@csv_file_path, {col_sep: ';'})                              
  end                                                                               
end

output = File.open('./test/minitest/fixtures/code_postaux_provisioning.rb', 'w')

  output.write("PostCode.create(code: '#{value[:code_postal]} #{value[:nom_commune]}')\n")    
end
