Rails 3.1錯誤捕獲

Question

我認爲Rails 3.1正在改變錯誤發生的方式。任何人都可以協助或證實此事？我試圖用Rails 3.1.0創建自定義錯誤頁面.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 

^^這不起作用。

config.consider_all_requests_local  = true 

這是在我的開發環境默認情況下。我假設Rails 3.1刪除了「action_controller」，但我無法在任何地方證實這一點。

謝謝！

Answer 1

我假設以下代碼出現在您的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 

如果是這樣，請嘗試更換這行：這一行

unless config.consider_all_requests_local 

（預Rails 3中，我認爲）：

unless ActionController::Base.consider_all_requests_local 

或本（後的Rails 3）：

unless Rails.application.config.consider_all_requests_local

我不相信馬特的解決方案將捕獲路由e Rails 3.0/3.1中的錯誤。

嘗試把你的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

運作良好，對我來說！
