Rails and Checkbox: Only allow one checkbox to be checked [duplicate]

This question already has an answer here:

• only select one checkbox 7 answers

I have a form in my rails app with checkboxes that I actually want to behave like a select with a list. I want my user to be only able to select one checkbox at a time (so if he clicks the other checkbox the originally selected checkbox is automatically unchecked). Here's my code :

<%= f.fields_for  :answer do |a| %>
    <%= a.label "Answer Type :" %>
    <br>
    <% Answer.answer_type.options.each do |option| %>
      <%= a.label option.first %>
      <%= a.check_box(:answer_type, { multiple: false}, option.first, nil) %>
      <br>
    <% end -%>
<% end -%>

Is there a nice rails way to achieve that ?
