Rails 3.1错误捕捉

问题描述

| 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

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

解决方法

我假设以下代码出现在您的ApplicationController中？

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

这行（我认为是Rails 3之前的版本）：

unless ActionController::Base.consider_all_requests_local

或此（Rails 3之后）：

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中：

# 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
