Trying to use a radio button as a selection list

I am new using rails, I am trying to add to a user form a list of icon images and the user should select the icon he wants to have as icon. My problem is that I want to save the selected image in a field from user called "icon_id", on my user_controller I have de function where I find all icons @icons = Icon.find(:all) When I submit the form it doesn't save the selected radio button in that field. I hope someone can help me! Thanks in advance!!!

My code is: <%= stylesheet_link_tag 'top' %>        <%= javascript_include_tag :defaults %> <%= error_messages_for :user %> <% form_for :user, :url => users_path do |f| -%>

  <div class="boxform"> <div id="formulario"> <fieldset>   <p><label for="login"><%= _('Login') -%></label><br/> <%= f.text_field :login %></p>

<p><label for="email"><%= _('Email') -%></label><br/> <%= f.text_field :email %></p>

<p><label for="password"><%= _('Password') -%></label><br/> <%= f.password_field :password %></p>

<p><label for="password_confirmation"><%= _('Confirm Password') -%></

<br/>

<%= f.password_field :password_confirmation %></p>     <p> <label> <%= _('Select the icon you would like to have if you don not have a gravatar at gravatars.com:')%> </label></p>

<% for icon in @icons %>      <img class="imgicon" src="/images/top/<%=icon.image%>"/>      <input type="radio" id="icon_id" name="icon_id" value="<%=icon.id %>"

<%end%></fieldset>

</div> <div id="boton">     <button type="submit"><span><em> <%=_('Sign Up') -%> </em></span></

</div> </div> <% end -%>

Whenever your controller doesn't respond to your parameters as expected, check your development log to see what parameters it received.

You'll probably find a bunch of params like this:

{ :user => { :login => 'foo', :email => 'bar' }, :icon_id => 61 }

Notice that icon_id is outside the user hash.

So, two problems:

<input type="radio" id="icon_id" name="icon_id" value="<%=icon.id %>"

First, you don't close the input tag.

Second, you don't nest icon_id within the user parameters in the name attribute of the input tag:

  <input type="radio" id="user_icon_id"                       name="user[icon_id]"                       value="<%=icon.id %>" />

Thank you Brandon I have done it this way: <input type="radio" id="user_icon_id" name="user[icon_id]" value="< %=icon.id%>" <%= if icon.id==1 then "checked" end%> style="background- color:#fff; color: #0198ff;" />
