Why are my scripts from lib/assets directory in a Rails application not executing, or erring out?

I'm trying to use ConnectWise API's in my Rails 3 application. I've built and tested an API using plain ruby and it's successful. Now I'm trying to add this script into lib/assets in my Rails app to run but It seems to be either not executing the script, or executing and failing without giving me any error output.

Here are the successful Ruby scripts:

CompanyApis Class:

require 'builder'
class CompanyApis
  def self.get_company
    cw_company_id = 21920
    integrator_company_id = 'COMPANY_ID'
    integrator_login_id = 'INTERGRATOR_LOGIN'
    integrator_password = 'INTEGRATOR PW'

    xml = Builder::XmlMarkup.new(:indent=>2)
    xml.instruct!
    xml.tag!('soap:Envelope',
             :'xmlns:soap' => 'http://ift.tt/sVJIaE',
             :xmlns => 'http://connectwise.com'){
      xml.tag!('soap:Body'){
        xml.tag!('GetCompany'){
          xml.tag!('credentials'){
            xml.CompanyId(integrator_company_id)
            xml.IntegratorLoginId(integrator_login_id)
            xml.IntegratorPassword(integrator_password)
          }
          xml.id(cw_company_id)
        }
      }
    }
  end
end

CwIntegrator Class:

require 'net/https'
require 'uri'
require 'nokogiri'
require './company_api'

class CwIntegrator
  cw_company_id = 21920
  cw_hostname = 'cw.host.com'
  companyapi_url = "https://#{cw_hostname}/v4_6_release/apis/2.0/CompanyApi.asmx"
  uri = URI.parse(companyapi_url)

  # Use for proxying to Kali
  #proxy_addr = '172.16.1.149'
  #proxy_port = 8080

  request = Net::HTTP::Post.new(uri.path)
  request.add_field('Content-Type', 'text/xml; charset=utf-8')
  request.add_field('SOAPAction', 'http://ift.tt/1GEDlOs')
  request.body = CompanyApis.get_company
  http = Net::HTTP.new(uri.host, uri.port)

  # Use for proxying to Kali
  #http = Net::HTTP.new(uri.host, uri.port, proxy_addr, proxy_port)

  http.use_ssl = true
  http.verify_mode = OpenSSL::SSL::VERIFY_NONE
  response = http.start {|h| h.request(request)}
  company_info = []
  xml_doc = Nokogiri::XML(response.body).remove_namespaces!
  company_name = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/CompanyName').text
  company_street_addr = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/StreetLines/string')[0].text
  begin
    company_street_addr2 = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/StreetLines/string')[1].text
  end
  company_city = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/City').text
  company_state = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/State').text
  company_zip = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/Zip').text
  company_country = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/Country').text
  company_status = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/Status').text
  company_phone = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/PhoneNumber').text
  company_fax = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/FaxNumber').text
  company_www = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/WebSite').text

  company_info += [company_name: company_name, cw_company_id: cw_company_id, company_name: company_name,
                   company_street_addr: company_street_addr, company_street_addr2: company_street_addr2,
                   company_city: company_city, company_state: company_state, company_zip: company_zip,
                   company_country:company_country,company_status: company_status, company_phone: company_phone,
                   company_fax: company_fax, company_www: company_www]

  puts(company_info)
end

Running this script has this output:

ruby cw_integrator.rb {:company_name=>"Orlando Fake Co, LLC.", :cw_company_id=>21920, :company_street_addr=>"STREET ADDR.", :company_street_addr2=>"Suite 400", :company_city=>"Orlando", :company_state=>"FL", :company_zip=>"32839", :company_country=>"United States", :company_status=>"Active Gold TTS", :company_phone=>"5558765309", :company_fax=>"", :company_www=>"www.myweb.com"}

So to add this to the Rails app I've added two .rb files to lib/assets, cw_apis.rb and cw_get_company_integrator.rb. Here are their contents:

CwApis class:

#!/usr/bin/env ruby
require 'builder'
class CwApis
  def self.get_company_xml_request
    cw_integrator_account = CwIntegratorAccount.first
    integrator_company_id = cw_integrator_account.integrator_company_id
    integrator_login_id = cw_integrator_account.integrator_login_id
    integrator_password = cw_integrator_account.integrator_password

    xml = Builder::XmlMarkup.new(:indent=>2)
    xml.instruct!
    xml.tag!('soap:Envelope',
             :'xmlns:soap' => 'http://ift.tt/sVJIaE',
             :xmlns => 'http://connectwise.com'){
      xml.tag!('soap:Body'){
        xml.tag!('GetCompany'){
          xml.tag!('credentials'){
            xml.CompanyId(integrator_company_id)
            xml.IntegratorLoginId(integrator_login_id)
            xml.IntegratorPassword(integrator_password)
          }
          xml.id(cw_integrator_account.cw_company_id)
        }
      }
    }
  end
end

And CwGetCompanyIntegrator Class:

#!/usr/bin/env ruby
require 'net/https'
require 'uri'
require 'nokogiri'
require 'assets/cw_apis'

class CwGetCompanyIntegrator
  cw_integrator_account = CwIntegratorAccount.first
  cw_hostname = cw_integrator_account.cw_hostname
  company_api_url = "https://#{cw_hostname}/v4_6_release/apis/2.0/CompanyApi.asmx"
  uri = URI.parse(company_api_url)

  request = Net::HTTP::Post.new(uri.path)
  request.add_field('Content-Type', 'text/xml; charset=utf-8')
  request.add_field('SOAPAction', 'http://ift.tt/1GEDlOs')
  request.body = CwApis.get_company_xml_request
  http = Net::HTTP.new(uri.host, uri.port)
  http.use_ssl = true
  http.verify_mode = OpenSSL::SSL
  response = http.start {|h| h.request(request)}
  xml_doc = Nokogiri::XML(response.body).remove_namespaces!

  company_name = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/CompanyName').text
  company_street_addr = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/StreetLines/string')[0].text
  begin
    company_street_addr2 = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/StreetLines/string')[1].text
  end
  company_city = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/City').text
  company_state = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/State').text
  company_zip = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/Zip').text
  company_country = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/DefaultAddress/Country').text
  company_status = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/Status').text
  company_phone = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/PhoneNumber').text
  company_fax = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/FaxNumber').text
  company_www = xml_doc.xpath('//Envelope/Body/GetCompanyResponse/GetCompanyResult/WebSite').text

  CompanyInfosController.create!(cw_company_id: cw_integrator_account.cw_company_id, company_name: company_name,
                                 company_street_addr: company_street_addr, company_street_addr2: company_street_addr2,
                                 company_city: company_city, company_state: company_state, company_zip: company_zip,
                                 company_country:company_country, company_status: company_status, company_phone: company_phone,
                                 company_fax: company_fax, company_www: company_www)
end

I'm trying to execute the CwGetCompanyIntegrator class in my CwIntegratorAccountsController.

Here is the code inside the create action from the CwIntegratorAccountsController:

require 'assets/cw_get_company_integrator'

class CwIntegratorAccountsController < ApplicationController
  skip_before_filter :require_company, :only => [:create,:new]

  # GET /cw_integrator_accounts
  # GET /cw_integrator_accounts.json

  def create
    unless CwIntegratorAccount.count >= 1
      @cw_integrator_account = CwIntegratorAccount.new(params[:cw_integrator_account])

      respond_to do |format|
        if @cw_integrator_account.save

          # Run the CW Integrator
          CwGetCompanyIntegrator
          format.html { redirect_to root_url, notice: 'cw_integrator success' }
          #format.json { render json: @cw_integrator_account, status: :created, location: @cw_integrator_account }
        else
          format.html { render action: 'new' }
          format.json { render json: @cw_integrator_account.errors, status: :unprocessable_entity }
        end
      end
    end
  end
end

What is the proper way to make this class execute?
