check_box in ruby on rails

I have two checkboxes that need to be exclusive.

%p Are you a Borrower or Lender?
        = f.check_box :borrower, {}, "true", "false"
        Borrower
        = f.check_box :lender, {}, "true", "false"
        Lender

How do you I change this so user can only select either borrower or lender option? As currently is, one could check both boxes.

EDIT #2:

So, from what I understand, I need to give the radio_button the same name in order to not confuse the browser and then define a method. Please provide some guidance on how to write such a method.

= f.radio_button(:lender_or_borrower, :lender)
Lender
= f.radio_button(:lender_or_borrower, :borrower)
Borrower

As you mentioned in your comment, since it semantically only makes sense to have one option selected at a time, you should either use a select or radio_buttons. For example a select could look like this:

f.select(:borrower_or_lender, [['Borrower, borrower'],  ['Lender', 'lender']])

Edit: As for radio buttons: both radio buttons need to have the same method/attribute (the first argument you pass to the helper):

= f.radio_button(:borrower_or_lender, 'borrower')
Borrower
= f.radio_button(:borrower_or_lender, 'lender')
Lender
