Trying to use a radio button as a selection list

Rails
1

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| -%>

<%= _('Login') -%>
<%= f.text_field :login %>

<%= _('Email') -%>
<%= f.text_field :email %>

<%= _('Password') -%>
<%= f.password_field :password %>

<%= _('Confirm Password') -%>
<%= f.password_field :password_confirmation %>

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

<% for icon in @icons %>

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

<%end%>

<%=_('Sign Up') -%>
<% end -%>

Sounds like you’re using restful_authentication, which uses
attr_accessible
to declare which attributes in the user model can be updated. If that’s
the
case, just add icon_id to the attr_protected declaration in your user
model.

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:

2 ways:

  1. set the value of the model field to the checkbox value
  2. <%= radio_button :model, :field, ‘val’, :checked => true %>

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;” />
