在Rails表单帮助器中从check_box转换为radio_button

Question

I have check_box inside my form like this below. I can select or deselect an item. But what I want is to select only one item from the group of options (items) that I have. How can I do that using radio_button ??

      <%= f.fields_for :items, @form_items do |fields| %>
        <% if editable %>
            <%= fields.hidden_field :unit_id %>
            <%= fields.check_box :_destroy, { checked: item.persisted?, class: 'add-item', "data-price" => item.pre_tax_amount, readonly: true }, '0', '1' %>
        <% end %>

Thanks in advance.

You should be able to use the collection_radio_button helper that rails provide using @form_items as the collection.

<%= fields.collection_radio_buttons :item, @form_items %>

This should give you a starting place; not knowing the contents of the collection makes it difficult to give a full example.
