model problems in vote system

I have three models Vote, Option and Number. I set up an index to input voting information such as title and description. How do I store the number of votes (in the Number model) using radio buttons?

My models have the following attributes:

Vote: name, description
Option: vote_id, content
Number: option_id, content (integer)

here is my edit.html i want to add vote-number function in this html,but i don't know how.so Can You give me some ideas to finish it? ^_^.i'm new in rails ,and thank you very much for helping me !!

<p id="notice"><%= notice %></p>

<p>
  <b>Name:</b>
  <%= @vote.name %>
</p>

<p>
  <b>Description:</b>
  <%= @vote.description %>
</p>

    <%  for option in @vote.options %>


    <%=h option.content %><br />


<%  end %>

This might point you in the right direction:

You'll want to use *fields_for* within your input form, and pass your second model to it. Rails should take care of the magic in the backend if your model association relationships (belongs_to, has_many etc.) have been set up correctly.
