因此，我刚刚与一位同事进行了激烈的宗教争论。

我们有对象模型和 routes.rb：

resources :orgs do
  resources :lists do
    resources :posts do
      resources :replies
    end
  end
end

所有这些关系都是一对多的，即一个列表将始终恰好属于 1 个组织，一个帖子将始终恰好属于 1 个列表等。我们非常清楚对多嵌套路由的普遍厌恶，但有意识地决定朝这个方向走。

不幸的是，这意味着当您想要链接到编辑回复时，您必须编写：

edit_org_list_post_reply_path( reply.post.list.org, reply.post.list, reply.list, reply )

感觉很傻。

我希望能够做类似的事情：

fast_path( action: :edit, model: reply, type: :path )

并利用回复仅属于一个帖子、属于一个列表等这一事实来计算其余部分。就像是：

def fast_path options
  action = options[:action]
  model = options[:model]
  path_or_url = options[:type]

  model_fields = {
    reply: [:org, :list, :post]
    post: [:org, :list],
    list: [:org]
  }[model.class.name]

  arguments = model_fields.map { |field| model.send(field) } + [model]
  named_route_name = model_fields.join("_") + "_" + path_or_url
  named_route_name = action + "_" + named_route_name if action

  send(named_route_name, arguments)
end

虽然我还没有验证这是否有效或者是特别好的代码。

但是，我的同事以前做过类似的事情，他重写了许多命名路线，以使它们更易于调用。他声称这只会导致痛苦、绝望和折磨，并且这次他正在竭尽全力将这些尝试排除在我们的代码之外。

我很高兴错了，所以请告诉我们您的想法！

如果您不想覆盖路径助手（无疑有充分的理由不这样做），您可以向Reply模型添加一个方法，如下所示：

def path_args  
  [post.list.org, post.list, post, self]
end

然后只需调用：edit_org_list_post_reply_path(*reply.path_args)。

你考虑过浅嵌套吗？

resources :orgs, shallow: true do
  resources :lists, shallow: true do
    resources :posts, shallow: true do
      resources :replies
    end
  end
end

然后你仍然会得到所有集合的深路径，但所有成员的浅路径：
