rails+radio_button_tag

In the code below I have used the radio buttons to select one option from Three options,

But, since the name of one radio button is different from other, i can able to select all the three options instead of one

I used this code because, i want to update records with all the three names from text box and its corresponded selected value,

Is there any other work around to do this

View 

<% 1.upto(3) do |i| %>
<%= text_field_tag "fields[#{i}][name]",'' %>
<%= radio_button_tag "fields[#{i}][answer]", '1', false%>
<% end %>

Controller

params[:fields].each do |i, values|
u = Sample.new
u.name = values["name"]
u.answer = values["answer"] ? 1 : 0
u.save
end

thanks,

First of all, nested attributes may be well suited for your problem. I'd recommend looking into those instead of the way you are approaching things now.

If you want to just stick with things the way they are you can make things work with a couple adjustments.

For radio buttons to work correctly you need to use a unique value (i) for each option:

<%= radio_button_tag "answer", i, false%>

Then in your controller

u.answer = params["answer"] == i ? 1 : 0

You probably want something like this:

<% 1.upto(3) do |i| %>
    <%= text_field_tag "fields[#{i}][name]",'' %>
    <%= radio_button_tag "fields[answer]", '#{i}', false%>
<% end %>

This will yield an answer field with a value of 1,2, or 3 depending on which one is selected.
