Devise:Module 的未定义方法“omniauth”（devise、omniauth、heroku、rails 3.0.3）

Question

我有一个在本地使用亚马逊产品广告 API 的应用程序，没有任何问题。为了将它推送到 Heroku，我必须更改我使用的 aws gem 版本以使其与 Heroku 一起使用（“treyconnell-ruby-aaws”v0.8.3），并且该版本将我限制为 Rails 3.0.3 和设计 v1.1.8 宝石。

当我降级 gem 和“捆绑更新”时，在本地出现了一些平衡，猜测omniauth 和设计开始战斗。服务器无法启动并显示以下错误日志。

我尝试了许多不同的配置来加载omniauth gem、oa-auth、需要omniauth/oauth 等，仍然是同样的错误。这里可能是什么问题？

PS。我现在必须使用这个 aws gem。

编辑：这里是 devise.rb 文件：

# Use this hook to configure devise mailer, warden hooks and so forth. The first
# four configuration values can also be set straight in your models.
Devise.setup do |config|
  config.mailer_sender = "please-change-me-at-config-initializers-devise@example.com"
  require 'devise/orm/active_record'
  config.omniauth :facebook, "1*************", "3******************************"
  config.case_insensitive_keys = [ :email ]
  config.stretches = 10
  config.use_salt_as_remember_token = true
  config.reset_password_within = 2.hours
end

Answer 1

我认为devise.rb 中的config.facebook 行让你很伤心。

我查看了我的 devise.rb，还有另一个名为 omniauth.rb 的文件。

(1) 我的devise.rb 没有config.facebook 行。尝试删除它，看看它是否有效。

(2) 我有一个名为omniauth.rb 的文件，与devise.rb 位于同一目录中。我把它贴在下面：

require 'openid/store/filesystem'

Rails.application.config.middleware.use OmniAuth::Builder do

  case Rails.env
  when "development"
    provider :facebook, 'XXX', 'XXXX' , {:scope => 'manage_pages,publish_stream,offline_access,email'}

  when "production"
    provider :facebook, 'XXX', 'XXXX', {:scope => 'manage_pages,publish_stream,offline_access,email', :client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}}}  
    end
end

看看这是否适合你。 :)
