Question

我需要匹配导致不匹配的复杂路由，这些是我的路由文件条目。

  match 'households/:id/edit'=>'households#edit', :via=>:get, :as=>:edit_household, :id=>/\d{1,5}/
  match 'households/:id' => 'households#update', :via => :put
  match 'households/:id' => 'households#destroy', :via=>:delete
  match 'households/:city_code-:region_code'=>'households#index', :via=>:get, :as=>:households, :city_code=>/[A-Z]{3,5}/, :region_code=>/[A-Z]{0,3}\d{0,5}/
  match 'households/:city_code-:region_code-:h_uid'=>'households#show', :via=>:get, :as=>:household, :city_code=>/[A-Z]{3,5}/, :region_code=>/[A-Z]{0,3}\d{0,5}/

现在的问题是请求

http://0.0.0.0:3000/households/9/edit

正在路由到show controller并且错误正在生成

路由错误

No route matches {:controller=>"households", :action=>"show", :format=>nil, :city_code=>#<Household id: 9, uid: "0004", house_no: "House No 12", street: "Street 512", address: "Lorem ipsum dolor sit amet, consectetur adipisicing...", region_id: 3, created_at: "2012-01-05 11:06:32", updated_at: "2012-01-05 11:06:32">}

Answer 1

我将路线改为：

  resources :households, :only=>[:index, :edit, :update, :destroy] do
    collection do
      match ':city_code-:region_code-:h_uid'=>'households#show', :via=>:get, :as=>:show, :city_code=>/[A-Z]{3,5}/, :region_code=>/[A-Z]{0,3}\d{0,5}/
    end
  end

并且每件事情都很好。

Answer 2

好像你不是将city_code传递给路线助手，而是传递对象：

:city_code => #<Household id: 9, uid: "0004", house_no: "House No 12", ... >

当然，它被路由器拒绝，因为它有一个约束：:city_code=>/[A-Z]{3,5}/。
