ruby-on-rails - 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这一点吗？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

^^ 这行不通。

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”，但我无法在任何地方确认这一点。

谢谢!

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

用这一行(我认为是 Rails 3 之前的版本):

unless ActionController::Base.consider_all_requests_local

或者这个(Rails 3 之后):

unless Rails.application.config.consider_all_requests_local
