ruby rails 中的管理员如何管理用户

Question

既然我只有一个模型和控制器（用户），我该如何以管理员身份管理和编辑其他用户的个人资料？

我尝试添加一个名为 updateusers 的新操作

def updateusers
    @other_user=User.find(params[:id])
    if @other_user.update_attributes(otherusers_params) 
            redirect_to '/' 
    else
            redirect_to '/manage'
   end
end

the problem here :it is updating my admin user with the other_user's data

Answer 1

"editusers" 中表单的用户 ID 设置为您的管理员（或登录用户）。没有看到代码很难说，但我认为您设置的 editusers 表单不正确。也许使用隐藏字段来保存要更新的用户的 ID。

尽量避免这种情况并在 'editusers' 操作中设置 @user 对象 @user = User.find(10) 然后在您的视图中使用没有任何隐藏字段的 form_for @user do |f| 作为 ID。

10 天后，是的，我做到了 - 解决方案是提交的名称，我用不同的名称命名了两个提交 <%= f.submit "update"，名称："other" %> 然后我使用了这样的更新操作

def update 
    if params[:current]
       @user = current_user
       if @user.update_attributes(user_params)
          redirect_to '/profile'
       else 
          redirect_to '/edit'
       end 

     elsif params[:other]
         @other_user=User.find(params[:id])
         if @other_user.update_attributes(otherusers_params)
            redirect_to '/'
          else 
             redirect_to '/manage'
          end 
     end 

end
