如何允許設計用戶編輯他們的profil？

我有一個叫做「backend」的名字空間，它受Devise保護。我現在想讓用戶編輯他們的profil。如何允許設計用戶編輯他們的profil？

所以我在後端創建了一個users_controller。這裏的users_controller代碼：

class Backend::UsersController < ApplicationController 
layout 'admin' 
before_filter :authenticate_user! 

    def index 
     @users = Backend::User.all 

     respond_to do |format| 
     format.html # index.html.erb 
     format.json { render json: @users } 
    end 
    end 

    def show 
    @user = Backend::User.find(params[:id]) 

    respond_to do |format| 
     format.html # show.html.erb 
     format.json { render json: @user } 
    end 
    end 

    def edit 
     @user = Backend::User.find(params[:id]) 
    end 

    def update 
    @user = Backend::User.find(params[:id]) 

    respond_to do |format| 
     if @user.update_attributes(params[:user]) 
     format.html { redirect_to @user, notice: 'Article was successfully updated.' } 
     format.json { head :no_content } 
     else 
     format.html { render action: "edit" } 
     format.json { render json: @user.errors, status: :unprocessable_entity } 
     end 
    end 
    end 
end

當我去backend_users_path有所有用戶的列表。我想允許編輯他自己的個人資料。所以我去編輯頁面：<%= link_to "Edit", edit_backend_user_path(backend_user.id) %>。這裏的編輯頁面代碼：

<%= simple_form_for @user do |f| %> 
    <div><%= f.label :email %><br /> 
    <%= f.input :email, :autofocus => true %></div> 

    <div><%= f.submit "Update" %></div> 
<% end %>

而且還有我的問題：當我試圖修改的電子郵件地址，沒有發生。更新失敗。

我該怎麼做？我很迷茫。提前致謝。

這裏的日誌文件：

感謝您的鏈接，我想修改我user_controller與

if params[:user][:password].blank? 
     params[:user].delete("password") 
     params[:user].delete("password_confirmation") 
    end 

    @user = User.find(current_user.id) 
    if @user.update_attributes(params[:user]) 
     # Sign in the user bypassing validation in case his password changed 
     sign_in @user, :bypass => true 
     redirect_to root_path 
    else 
     render "edit" 
    end

但它失敗...

如果沒有反應，那通常會顯示一個驗證錯誤，在您的情況下可能是密碼丟失或其他數據不屬於您的表單，但仍在驗證中。要進行調試，請將@user.errors.inspect輸出到您的日誌文件或在您的視圖中查看error_messages_on @user。

一般來說，看看如何允許用戶編輯自己的（部分）簡介這些指南：

感謝關心我的問題。我將用de日誌和更多信息編輯我的帖子。 –

請分享錯誤訊息，它應該在'@ user.errors'中。 – Thilo
