FactoryGirl 助手导致 Heroku 失败答案

【问题标题】：FactoryGirl helper causing Heroku to failFactoryGirl 助手导致 Heroku 失败
【发布时间】：2015-01-31 02:56:57
【问题描述】：

我的 Heroku 应用由于“缺少帮助文件 helpers/factory_girl.rb”而崩溃，即使它可以在本地运行并且FactoryGirl 仅安装在我的 Gemfile 测试组中。

为什么 Heroku 要求我的 FactoryGirl 助手在开发中不需要并且未指定为生产 gem？
helpers/factory_girl.rb 应该是什么样子？我在网上搜索并找不到任何东西。一个完全空白的文件可以工作吗？

我正在运行 Rails 3.2.13、Ruby 2.0.0-p481 和 factory_girl_rails 4.4.1。

宝石文件：

group :test do
  gem "factory_girl_rails", ">= 4.0"
end

Heroku 日志：

【问题讨论】：

helpers/factory_girl.rb上写的是什么路径和内容？路径是app/helpers/factory_girl.rb？还有，FactoryGirl.define do ... end?请与我们分享。

【解决方案1】：

我认为 heroku 的 RAILS_ENV 是生产如下。

$ heroku config                                                                                                                                                                                   
=== app_name Config Vars
CLEARDB_DATABASE_URL: mysql://...
DATABASE_URL:         mysql2://...
LANG:                 en_US.UTF-8
RACK_ENV:             production
RAILS_ENV:            production
SECRET_KEY_BASE:      ....

这就是为什么 测试组 中的factory_girl 在heroku 上不能正常工作的原因。解决方案之一是添加 production 组。但是，这不是个好主意。

group :test, :production do
  gem "factory_girl_rails", ">= 4.0"
end

我想如果你只是在heroku上加载测试数据进行测试，我建议如下。

# run to load test data
rake db:data_import

# test data import rake file
# deta_import.rb
if Rails.env.production?
  require "factory_girl_rails"
  FactoryGirl.find_definitions
end
... test data import with FactoryGirl ...

【讨论】：

Shoji，我不想进行任何测试。当我尝试访问我的应用程序时，Heroku 给我一个应用程序错误。我还尝试了您的第一个想法（也将 FactoryGirl 投入生产），但没有奏效。
等等，实际上 - 我认为你的第一个想法确实奏效了。我不知道第二个如何解决我当前的问题，因为 Heroku 正在抛出应用程序错误，因为它找不到 FG 的助手。
