將struct分配給在開發中工作的數組，但不在Heroku上

Ruby on Rails應用程序在開發中工作，但在Heroku中崩潰。在應用程序中，我將值放入一個結構體（Selection）中，然後將其加載到數組（@selections）中，以便在屏幕上選擇下拉窗口。我找到了導致此錯誤的行，請參閱rails代碼和Heroku日誌中的print語句，但不知道如何解決此問題。已嘗試了一些替代品，但迄今沒有運氣。當我在我的gemfile中指定ruby版本（ruby'1.9.3'）時，我的理解是Heroku會使用此版本的Ruby（例如，不是由不同版本的Ruby引起的錯誤）。將struct分配給在開發中工作的數組，但不在Heroku上

鑽取控制器

Selection = Struct.new(:id, :name, :table_index, :user_valuation) 

class DrillsController < ApplicationController 
    before_filter :current_user 
    before_filter :load_drill, except: [:index, :new, :create] 
    ….. 
    def load_evaluation_assumption_selections 
    load_stake 
    @selections = [] 
    list_of_companies = [] 
    index = 0 
    @resource_estimations = @drill.resource_estimations 
    if @resource_estimations.present? 
     @resource_estimations.each do |u| 
     unless list_of_companies.include?(u.company_id) 
      list_of_companies.push(u.company_id) 
      if u.company_id == @stake.company_id 
      company_name = "default" 
      else 
      company_name = u.company.name 
      end 
      puts "ZZZZZ - before load struct, Selection, to array @selections" 
      @selections += [Selection.new(index, company_name, u.id, false)] 
      puts "ZZZZZ - after load struct, Selection, to array @selections"   
      index += 1 
     end 
     end 
    end

我也嘗試使用紅寶石「@ selections.push（Selection.new（index，company_name，u.id，false））」，我使用IRB檢查了很好，但是這個在Heroku中沒有用。 – user1854802
