Rails 3.1错误捕获

Question

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!

Answer 1

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!
