沒有路由匹配丟失所需的鍵：[：id]

Question

我對rails非常陌生，並且正在編輯最初由其他人編寫的代碼，所以我可能需要比普通人更深入的響應。 。

我遇到這個錯誤，當我運行rake： No route matches {:controller=>"users", :action=>"show", :id=>nil, :format=>nil} missing required keys: [:id]

，似乎是引起該問題的線路是這樣的：

<%= link_to("My Account", user_path(current_user)) %>

鏈路的實際工作正常上羅calhost，但未能在該行本次測試「渲染：模板」：

it "renders new initiative form" do 
    assign(:initiative, Initiative.new(location: Location.new,rewards:  [FactoryGirl.create(:reward)])) 
    render :template => "initiatives/new.html.erb" (...etc.) 

不知道還有什麼是有用的，包括在這裏，但UsersController是：從耙路線

class UsersController < ApplicationController 
    def show 
    @user = User.find(params[:id]) 
    end 
end 

和結果：

       admin_users GET  /admin/users(.:format)       admin/users#index

也許有人可以幫忙嗎？

在呈現模板之前，您應該使用Devise登錄助手進行登錄。 https://github.com/plataformatec/devise/wiki/How-To:-Test-with-Capybara
