从rails控制器中的嵌套表单保存信息

我正在尝试为我的网站设置一个简单的角色模型。用户可以拥有任意数量的角色。现在我将它设置为注册表单上的隐藏字段。我遇到的问题是,在我的嵌套表单中,角色类型没有被保存。正在角色表中创建一个带有uid的条目,但这是关于它的。相关代码如下。任何帮助,将不胜感激。

 == Schema Information

 Table name: roles

  id         :integer         not null, primary key
  user_id    :integer
  role       :string(255)
  created_at :datetime        not null
  updated_at :datetime        not null

来自我的用户控制器的创建方法......

def create
 @user = User.new(params[:user])  
if @user.save   
  @role = @user.roles.new(user_id:@user.id, role:params[:role])

  flash[:success] = "Thanks for singing up for the Auditions App, any audition invitations will be visible on this page"                 
  #need to add the role guest to user roles
  redirect_to @user
else
  render 'new'
end

结束

继承人的形式......

<div class="span10 offset1 ajax-form">   
<%= form_for(@user, :html => {:class => 'well'}) do |f| %> 

        <h3>Guest Account Signup</h3>

      <%= render 'shared/error_messages' %>

      <div class="pull-left form-field"><%= f.label :first_name %>
  <%= f.text_field :first_name, :class => 'span4' %></div>
  <div class="pull-left form-field"><%= f.label :last_name %>
  <%= f.text_field :last_name, :class => 'span4' %></div>
  <div class="pull-left form-field"><%= f.label :email %>
  <%= f.text_field :email, :class => 'span4' %></div>                                           
  <div class="pull-left form-field span4"></div>
         <div class='clear'></div><!--close .clear-->

  <div class="pull-left form-field"><%= f.label :password %>
  <%= f.password_field :password, :class => 'span4' %></div>
  <div class="pull-left form-field"><%= f.label :password_confirmation, "Confirm Password" %>
  <%= f.password_field :password_confirmation, :class => 'span4'  %></div>
        <div class="form_row pull-left form-field">
        </div>

            <%= f.hidden_field :role, :value => 'guest' %>

  <%= f.submit "Create my account", :class => "btn btn-large btn-primary pull-left form-field" %>
        <div class='clear'></div><!--close .clear-->
<% end %>

作为@Arpit评论 - 摆脱hidden:user_id标签。它只会混淆属性设置器。

我不认为使用roles.new()构建多个角色(与roles.build()相同吗?)会削减它。您需要分解单独的角色参数并一次添加一个。或者你可以像这样一次抓住它们:

selected_roles = Role.find_all_by_id(params[:roles])
@user.roles = selected_roles

这会假设您在表单中使用了角色ID,但您出于某种原因......
