找不到没有ID的[型号] - ransack - rails 4

Question

我是铁杆的新手，我们将不胜感激。

我实现了宝石搜索，每当我点击我的应用程序的搜索按钮时，我都会得到图像下方的错误

我的终端目前有以下错误：

Started GET "/adverts?utf8=%E2%9C%93&q%5Btitle_cont%5D=accountant&commit=search" for 127.0.0.1 at 2015-06-13 20:17:47 +0100
Processing by AdvertsController#index as HTML
  Parameters: {"utf8"=>"✓", "q"=>{"title_cont"=>"accountant"}, "commit"=>"search"}
Completed 404 Not Found in 4ms (ActiveRecord: 0.7ms)

ActiveRecord::RecordNotFound (Couldn't find Userr without an ID):
  app/controllers/adverts_controller.rb:16:in `index'

  

我不确定为什么我会得到上述错误以及为什么它指向我   我的advert_controller.rb的索引操作，而不是指向   我的static_pages_controller.rb的搜索动作

     

任何帮助或建议，以扩大我对此错误的理解   将不胜感激。我有我所有的编码

adverts_controller.rb

class AdvertsController < ApplicationController
  respond_to :html, :xml, :json
  before_action :set_advert, only: [:show, :edit, :update, :destroy]

  def index
    @userr = Userr.find(params[:userr_id])
    @adverts = @userr.adverts.order("created_at DESC")
    respond_with(@adverts)
  end

  def show
...
  end

  def new
...
  end

  def edit
...
  end

  def create
...

  def update

  def destroy

static_pages_controller.rb

class StaticPagesController < ApplicationController
  respond_to :html, :xml, :json

 def searchpg
    @search = Advert.search(params[:q])
    @adverts = @search.result
