Rails 3:仅在特定方法中出现路由错误 [英] Rails 3: Routing error only in a certain method

问题描述

我的 routes.rb 中的某个记录出现了奇怪的行为.这是我的 routes.rb 的摘录:

I am experiencing a strange behavior for a certain record in my routes.rb. Here is an excerpt of my routes.rb:

resources :stores do
  resources :stores_spare_parts do
    collection do
      post :update_attribute_on_the_spot
    end
  end
end

当我现在在我的 store_spare_parts 控制器的索引操作中调用方法 url_for 时，它返回 http://127.0.0.1:3000/stores/1/stores_spare_parts/update_attribute_on_the_spot.但是，当我在创建操作中执行相同操作时，它会因以下错误而停止工作:

When I now call the method url_for in my index action of the stores_spare_parts Controller, it returns http://127.0.0.1:3000/stores/1/stores_spare_parts/update_attribute_on_the_spot. But when I do the same in my create action it stops working with the following error:

ActionController::RoutingError
(No route matches  {:action=>"update_attribute_on_the_spot",
:controller=>"stores_spare_parts"}):
app/controllers/stores_spare_parts_controller.rb:19:in `block in create'
app/controllers/stores_spare_parts_controller.rb:19:in `create'

这里是索引和创建方法的控制器代码:

Here is the controller code for the index and the create method:

def index
  Rails.logger.debug { "---------------------------" }
  Rails.logger.debug { url_for(:action => 'update_attribute_on_the_spot') }
  Rails.logger.debug { "---------------------------" }

  @currentStore = Store.find(params[:store_id])
  @activeStores = Store.scoped_by_deactivated(false)
  @storesSpareParts = StoresSparePart.scoped_by_store_id(@currentStore.id)
end

def create
  Rails.logger.debug { "---------------------------" }
  Rails.logger.debug { url_for(:action => 'update_attribute_on_the_spot') }
  Rails.logger.debug { "---------------------------" }

  return

  @newStoreSparePart = StoresSparePart.new(params[:stores_spare_part])

  if @newStoreSparePart.save
    flash[:notice] = "Successfully updated spare part for store #{@newStoreSparePart.store.title}."
    @currentStore = @newStoreSparePart.store
    @activeStores = Store.scoped_by_deactivated(false)
    @storesSpareParts = StoresSparePart.scoped_by_store_id(@currentStore.id)
    Rails.logger.debug { @currentStore.title }
    Rails.logger.debug { @storesSpareParts.count }
    render 'create.js'
  else
    render 'create.js'
  end
end

这是传递给 create 方法的 POST 请求:

Here is the POST request passed to the create method:

Started POST "/stores_spare_parts" for 127.0.0.1 at 2011-05-02 17:52:00 +0200
Processing by StoresSparePartsController#create as JS
Parameters: {"utf8"=>"✓", "authenticity_token"=>"+NKTAC8ibgUW8vYg5H0XcWB+hAoFdw6on3Uw2XfP9WQ=",

"lowMark"=>"", "store_id"=>"1"}, "commit"=>"Create Stores spare part"}

推荐答案

将 post :update_attribute_on_the_spot 更改为 put :update_attribute_on_the_spot 因为看起来您正在更新记录(put) 而不是创建记录 (post).我很确定 RoR 有一次因为我做了你所做的事情而生我的气.

Change post :update_attribute_on_the_spot to put :update_attribute_on_the_spot since it looks like you are updating a record (put) and not creating a record (post). I am pretty sure RoR got mad at me one time for doing something like what you did.
