刚开始学习ruby，所以提前抱歉任何愚蠢的错误。无论如何，每当我尝试以“客户”身份登录时，以下是由于客户资料中的“更新”按钮而产生的错误。

@user = current_user

以下是因为我的cust_home.html页面中的“更新”按钮而生成的错误
Easy＃home
中的ActionController :: UrlGenerationError没有路由匹配{：action =＆gt;“edit”，：controller =＆gt;“cust_profiles”，：id =＆gt; nil}，缺少必需的密钥：[：id]
我怀疑错误来自我的控制器，但无法弄清楚如何继续。
修改
的routes.rb
Rails.application.routes.draw do
resources :cuisines
resources :cook_profiles
resources :cust_profiles
devise_for :users, :controllers => {:registrations => 'registrations'}
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
#----- Home routes
get 'home', to: 'easy#home', as: 'easy_home'
get 'cook_home', to: 'easy#cook_home', as: 'cook_home'
get 'cust_home', to: 'easy#cust_home', as: 'cust_home'
get 'admin_home', to: 'easy#admin_home', as: 'admin_home'
root to: 'easy#home'
#----- Route to user-appropriate profile page
get '/profile', to: 'easy#profile', as: 'profile'
end
答案 0 :(得分：0)
错误不是由Update按钮引起的。它来自：
ActionController::UrlGenerationError in Easy#home
因此，您必须检查EasyController#home的视图。当您查看它（cust_home.html）时，只有一个地方可能导致此问题：
<%= link_to 'Update', edit_cust_profile_path(current_user.cust_profile) %>
因为它说：
No route matches {:action=>"edit", :controller=>"cust_profiles", :id=>nil}, missing required keys: [:id]
可能current_user.cust_profile是nil。
