Rails 3：使包罗万象的路线更易于阅读和修改

发布于 2024-12-08 19:28:35 字数 1160 浏览 0 评论 0 原文

我正在尝试在 Rails 3 中编写一条包罗万象的路线，但我想在其中保留一些术语。我特别遵循 David Burrows 的回答中这篇文章中提出的示例：动态路线在 Rails 3 中，

我使用的语法如下：

match '*path' => 'router#routing', :constraints => lambda{|req|  (req.env["REQUEST_PATH"] =~ /(users|my-stuff)/).nil? }

现在，该语法工作得很好 - 如果用户访问路径中包含“user”或“my-stuff”的页面，它就会陷入困境 -全部并转到具体的地方。如果用户访问任何其他 URL，它将进入我的路由逻辑。

我的问题更多的是关于可读性 - 有没有办法可以将路由与正则表达式之外的其他内容进行匹配？有没有办法提供一系列要匹配的术语？另外，有没有办法匹配路线的特定部分，而不是整个路线？

显然，Rails 具有内置路由，但该项目要求对于某些路由，控制器不能出现在 URL 中。因此，包罗万象。

感谢您的帮助

这是根据以下答案更新的路线文件：

class RouteConstraint
  RESERVED_ROUTES = ['users', 'my-stuff']

  def matches?(request)
    !RESERVED_ROUTES.map {|r| request.path.include?(r)}.empty?
  end
end

App::Application.routes.draw do
  resources :categories
  resources :sites

  match '*path' => 'router#routing', :constraints => RouteConstraint.new

  devise_for :users, :path_names =>{ :sign_in => 'login', :sign_out => 'logout', :registration => 'register' }
  root :to => "router#routing"
end

I'm trying to write a catch-all route in Rails 3, but I want to reserve some terms in it. I'm specifically following the example put forth in this post, in the answer by David Burrows: Dynamic routes with Rails 3

The syntax I am using is the following:

match '*path' => 'router#routing', :constraints => lambda{|req|  (req.env["REQUEST_PATH"] =~ /(users|my-stuff)/).nil? }

Now, that syntax works just fine - if a user visits a page with "user" or "my-stuff" in the path, it falls through the catch-all and goes to a specific place. If the user goes to any other URL, it goes to my routing logic.

My question is more about readability - is there a way I can match the route against something other than a regex? Is there a way to provide an array of terms to match against? Also, is there a way to match specific segments of the route, as opposed to the entire thing?

Obviously Rails has built-in routing, but this project has a requirement that for certain routes, the controller not be present in the URL. Hence, the catch-all.

Thanks for any help

Here's the updated routes file per the answer below:

class RouteConstraint
  RESERVED_ROUTES = ['users', 'my-stuff']

  def matches?(request)
    !RESERVED_ROUTES.map {|r| request.path.include?(r)}.empty?
  end
end

App::Application.routes.draw do
  resources :categories
  resources :sites

  match '*path' => 'router#routing', :constraints => RouteConstraint.new

  devise_for :users, :path_names =>{ :sign_in => 'login', :sign_out => 'logout', :registration => 'register' }
  root :to => "router#routing"
end

一旦您有多个路线可供尝试，如果您想要更清晰的内容，您可以使用类来指定约束：

class MyConstraint
  BYPASSED_ROUTES = ['users', 'my-stuff']

  def matches?(request)
    BYPASSED_ROUTES.map {|r| request.path.include?(r)} .empty?
  end
end

TwitterClone::Application.routes.draw do
  match "*path" => "router#routing", :constraints => MyConstraint.new
end

此示例改编自 Rails 路由指南。

You can use a class to specify the constraints if you want something cleaner once you have multiple routes to try:

class MyConstraint
  BYPASSED_ROUTES = ['users', 'my-stuff']

  def matches?(request)
    BYPASSED_ROUTES.map {|r| request.path.include?(r)} .empty?
  end
end

TwitterClone::Application.routes.draw do
  match "*path" => "router#routing", :constraints => MyConstraint.new
end

This example is adapted from the rails routing guide.
