Question

我想根据数据库表中的type列为我的网址添加后缀。

# shop_controller.rb
...
def near
  @shop = Shop.find(params[:id])
  @type = @shop.type
end

# routes.rb
resources :spots do
  member do
    get :near
  end
end

我的网页目前位于app/views/shops/nearby.html.erb。目前生成的网址是：

http://localhost/shops/1/near

我没有为不同的类型创建多个页面：nearby_country.html.erb，nearby_state.html.erb，nearby_city.html.erb这不是RESTful，我宁愿在此网址上附加类型来按类型过滤商店，以便将来当我有更多类型时，它会自动显示：

http://localhost/shops/1/near_country
http://localhost/shops/1/near_state
http://localhost/shops/1/near_city

我也希望能够为我的菜单执行自定义路径，如：

nearby_country_shop_path
nearby_state_shop_path
nearby_city_shop_path

有人可以提供一些提示吗？谢谢！

Answer 1

见3.1节：

http://guides.rubyonrails.org/routing.html

但你可能不得不使用以下路线：

http://localhost/shops/1/near?country
http://localhost/shops/1/near?state
http://localhost/shops/1/near?city

另见：

http://railscasts.com/episodes/203-routing-in-rails-3

http://railscasts.com/episodes/231-routing-walkthrough

Answer 2

这不是您要求的，但您可以在路线中添加参数x，例如。

resources :spots do
  member do
    get 'near/:x', :action => :near, :as => :near
  end
end

这应该为您提供以下网址：

/spots/1/near/country
/spots/1/near/state
/spots/1/near/city

..和路线如：

near_spot GET /spots/:id/near/:x(.:format) {:action=>"near", :controller=>"spots"}

..和url助手如：

near_spot_path(spot_id, :country)
near_spot_path(spot_id, :state)

等
