Radio_button_tag syntaxis with more parameters

Rails
1

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-’)

…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:

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