Radio_button_tag syntaxis with more parameters

Hi to everybody!

I have a view with a radio-button: I need to pass 2 parameters
("opt.id" and "opt.option") to the relative action;
as for the following code I 've used, I find in params[:option_id]
only the id of the selected option...
How can I do to pass also "opt.option"?

      <% for opt in @options %>
            <p>
              <%= label_tag(:answer, opt.option) %>
              <%= radio_button_tag(:option_id, opt.id, false) %>
            </p>
      <% end %>

Thank's to all those who can help me!!!

If you're generating these options, shouldn't you know what option
goes with an id? :slight_smile:

Ruby programmers don't use for-in loops. for-in calls each(), so ruby
programmers just call each() directly:

<% @options.each do |opt| %>

<% end %>

            <p>
              <%= label_tag(:answer, opt.option) %>
              <%= radio_button_tag(:option_id, opt.id, false) %>
            </p>
      <% end %>

You could always do this:

<% val = "#{opt_id}-xYz-#{opt.option}" %>
<%= radio_button_tag(:option_id, val, false) %>

Then in your action:

radio_button_results = params[:option_id].split('-xYz-")

              <%= radio_button_tag(:option_id, opt.id, false) %>

..and shouldn't that label tag be something like this:

<%= label_tag("option_id_{#opt.id}", opt.option) %>

In other words, according to the rails guide here:

http://guides.rubyonrails.org/form_helpers.html

...the id of the radio button becomes the name and value you specify for
the radio_button_tag joined together.

THANK YOU VERY VERY MUCH!!! :wink:
