嵌套形式与设计 [英] Nested form with devise

问题描述

这是我的注册表单：

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>

  <p><%= f.label :email %><br />
  <%= f.email_field :email %></p>

  <p><%= f.label :password %><br />
  <%= f.password_field :password %></p>

  <p><%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation %></p>

  <%= f.fields_for :profile do |t| %>
     <div class ="field">
        <%= t.label :type, "Are you an artist or listener?" %><br />
        <p> Artist: <%= t.radio_button :type, "Profile::Artist", :id => "artist_button" %></p>
        <p> Listener: <%= t.radio_button :type, "Profile::Listener", :id => "listener_button" %></p>
      </div>
  <% end %>

  <p><%= f.submit "Sign up", :id => "new_user_submit" %></p>
<% end %>

我的用户型号还有：

 accepts_nested_attributes_for :profile

然而问题是嵌入表单的单选按钮甚至不会显示在页面上。如何解决这个问题？

However the problem is that the radio buttons that is nested in the form is not even appearing on the page. How can I fix this?

推荐答案

你可能需要在你的User对象上建立一个空的配置文件对象首先：

You probably need to build an empty profile object on your User object (or whatever it's called) first:

@user.build_profile
