我有一个名为“后端”的命名空间，它受设计保护。我现在想允许用户编辑他们的个人资料。

所以我users_controller在后端创建了一个。这是users_controller代码：

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

当我继续时，backend_users_path有一个所有用户的列表。我想只允许编辑他自己的个人资料。所以我去编辑页面：<%= link_to "Edit", edit_backend_user_path(backend_user.id) %>。这是编辑页面代码：

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

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

还有我的问题：当我尝试修改电子邮件地址时，什么也没有发生。更新失败。

我怎样才能做到这一点 ？我很迷茫。提前谢谢。

这是日志文件：

感谢您的链接，我试图修改我user_controller的

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

但它失败了......

如果什么也没发生，这通常表示验证错误，在您的情况下，可能是缺少密码或其他不属于您的表单但仍在验证中的数据。要对此进行调试，请输出@user.errors.inspect到您的日志文件或查看 error_messages_on @user您的视图。

一般来说，请查看这些指南，了解如何允许用户编辑他们的（部分）个人资料：
