我正在尝试使用以下代码为我的RoR应用程序设置自定义错误页面:
unless Rails.application.config.consider_all_requests_local
rescue_from Exception, :with => :render_error
rescue_from ActiveRecord::RecordNotFound, :with => :render_not_found
rescue_from ActionController::RoutingError, :with => :render_not_found
rescue_from ActionController::UnknownController, :with => :render_not_found
rescue_from ::ActionController::UnknownAction, :with => :render_not_found
end
我启动Web服务器后出现问题,我收到以下错误消息:
我尝试基于其他帖子使用ActionController::UnknownAction没有::但这似乎没有用.

ActionController::UnknownAction 在Rails 3.2中被弃用,赞成AbstractController::ActionNotFound.您正在使用Rails 4,其中该类不再存在.
将您的班级名称重命名为新名称AbstractController::ActionNotFound,您应该全部设置.
