Rails 3.1错误捕获

Question

我认为Rails 3.1正在改变错误发生的方式。任何人都可以协助或证实此事？我试图用Rails 3.1.0创建自定义错误页面.rc1

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 

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

谢谢！

Answer 1

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，请尝试更换这行：这一行

unless config.consider_all_requests_local 

（预Rails 3中，我认为）：

unless ActionController::Base.consider_all_requests_local 

或本（后的Rails 3）：

unless Rails.application.config.consider_all_requests_local

我不相信马特的解决方案将捕获路由e Rails 3.0/3.1中的错误。

尝试把你的application.rb中如下：

# 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

运作良好，对我来说！
