ruby-on-rails - 从路由错误轨道 3.1 中拯救

Question

如何从RoutingErrorRails 3.1 应用程序中救援。如果我没记错的话，可以rescue_from RoutingError在应用程序控制器中使用，但现在不可能。

Answer 1

There is no great way to handle it, but there are a few workarounds. The discussion here yields the following suggestion:

Routes

Add the following to your routes file:

match "*", :to => "home#routing_error"

and handle the error in this action:

def routing_error
  render text: "Not found, sorry", status: :not_found
end

Answer 2

我无法复制@matthew-savage 的结果。但是，根据 Rails guide on route globbing和this question on another StackOverflow question，我这样解决了这个问题：

路线.rb

match "*gibberish", :to => "home#routing_error"

请注意我是如何在通配符之后包含文本的。控制器很好，如上图所示：

控制器/home_controller.rb

....
def routing_error
    render text: "Not found, sorry", status: :not_found
end

Answer 3

好例子。

路由.rb

• 导轨 3：

  match '*unmatched_route', :to => 'application#raise_not_found!'

• 导轨 4：

  get '*unmatched_route' => 'application#raise_not_found!'

application_controller.rb

def raise_not_found!
  raise ActionController::RoutingError.new("No route matches #{params[:unmatched_route]}")
end
