Rails 3.1错误捕获

我认为Rails 3.1正在改变引发错误的方式。 任何人都可以协助或确认吗? 我正在尝试使用Rails 3.1.0.rc1创建自定义错误页面

unless 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 

^^这不起作用。

 config.consider_all_requests_local = true 

默认情况下,这是在我的开发环境中。 我假设Rails 3.1删除了“action_controller”但我无法在任何地方确认这一点。

谢谢!

我假设您的ApplicationController中出现以下代码?

 unless 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 

如果是这样,请尝试替换此行:

 unless config.consider_all_requests_local 

用这一行(我认为是前Rails 3):

 unless ActionController::Base.consider_all_requests_local 

或者这个(发布Rails 3):

 unless Rails.application.config.consider_all_requests_local 

我不相信Matt的解决方案会在Rails 3.0 / 3.1中捕获路由错误。

尝试将以下内容放入application.rb:

 # 404 catch all route config.after_initialize do |app| app.routes.append{ match '*a', :to => 'application#render_not_found' } unless config.consider_all_requests_local end

对我来说工作得很好!
