Question

我有一个用户模型和个人资料模型如下

 class User < ActiveRecord::Base
   has_one :profile
   accepts_nested_attributes_for :profile
   attr_accessible :gender,:mobile_number, :profile_attributes
   #...
 end

profile.rb：

 class Profile < ActiveRecord::Base
   belongs_to :user
   attr_accessible :twitter_url, :fb_url
   #...
 end

我的表单页面：

<%= simple_form_for current_user do |f| %>
  <%= f.input :gender, required: true %>
  <%= f.input :mobile_number, required: true %>
  <%= f.simple_fields_for :profile do |p| %>
    <%= p.input :twitter_url %>
    <%= p.input :fb_url %>
  <% end %>
  <%= f.submit "Save" %>
<% end %>

我收到以下错误

 ActiveModel::MassAssignmentSecurity::Error - Can't mass-assign protected attributes: gender, mobile_number, profile_attributes:

我已经在attr_accesible中指定了属性，但我不明白为什么我仍然会收到此错误。请帮忙。

即使在attr_accessible中指定属性后，也无法分配错误
