Question

Rails 3.2。在这里，我想指示所有http://domain.dev/toys仅显示shops shop_type（在我的表格列中）为toys的所有# routes.rb resources :shops match 'toys' => 'shops#index', :as => :toys, :via => :get, :constraints => {:shop_type => 'toys'} # shops_controller.rb def index @shops = Shop.find(:all) end。

{{1}}

我做错了什么？感谢。

Answer 1

错误的部分：Shop.find(:all)。

Constraints are for route segments.

（嗯，动词，但是它们是用:via指定的;或Request上的方法。）

Answer 2

在routes.rb：

match 'shops(/:shop_type)' => 'shops#index', :via => :get, :as => :shops_path

在shops_controller.rb：

SHOP_TYPES = [:toys, :clothing, :accessories]

def index
    @shops = []
    if SHOP_TYPES.include? params[:shop_type].to_sym
        @shops = Shop.find_all_by_shop_type(params[:shop_type])
    else
        @shops = Shop.find(:all)
    end
end

在路径中传递参数
