Question

我已经使用Mongoid，Devise和Omniauth为Facebook登录构建了一个基本的Rails应用程序。我在本地运行它没有问题，但是当我尝试推送到Heroku时，我收到了这个错误：

"/app/app/controllers/Users/omniauth_callbacks_controller.rb:1:in `': uninitialized     constant Users (NameError)"

我用一点运气用谷歌搜索出了这个地狱。我已经提交了User模型，我已经运行了“heroku run rake db：migrate”等等。没有运气。这是我的筹码。

Ruby 1.9.2
Rails 3.2.1

控制器：

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
  # You need to implement the method below in your model
@user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)

if @user.persisted?
  flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook"
  sign_in_and_redirect @user, :event => :authentication
else
  session["devise.facebook_data"] = request.env["omniauth.auth"]
  redirect_to new_user_registration_url
end
end
end

有什么想法吗？

Answer 1

我有这个问题;我知道这是一个迟到的答案，但我想为那些需要它的人添加它。

确保您的OmniauthCallbacksController处于users个文件夹中。 "app/controllers/users/omniauth_callbacks_controller.rb"

Answer 2

不太可能，但是如果您使用“rails generate scaffold”或“rails generate controller”来创建控制器，则需要“git add -A”将所有新创建的文件添加到您的存储库。（1）git add -A（2）git commit -m“新文件添加”（3）git push [假设你也使用远程仓库]（4）git push heroku master（5）heroku run rake db：迁移

这将是一个“新秀错误”，但会解释上面的错误。不要问我怎么知道！

Answer 3

我想补充说我有这个问题，上述解决方案对我不起作用。事实证明，我的案例中的原因是Devise已经将Users子文件夹的名称（/ app / app / controllers / Users）大写。从git中删除文件夹然后使用正确的小写名称“users”（/ app / app / controllers / users）读取它解决了我的问题。
