Module
ActionView::Helpers::FormHelper
radio_button(object_name, method, tag_value, options = {})
Returns a radio button tag for accessing a specified attribute
(identified by method) on an object assigned to the template (identified
by object). If the current value of method is tag_value the radio button
will be checked. Additional options on the input tag can be passed as a
hash with options.
Let's say that @post.category returns "rails":
radio_button("post", "category", "rails")
radio_button("post", "category", "java")
Or
radio_button("user", "receive_newsletter", "yes")
radio_button("user", "receive_newsletter", "no")
