Rails - list of years in HAML search form

How can I have a开发者_开发知识库 search form have a list of years?

Parameters:

• Rails3
• Is not tied to a database object
• Should use current year and have a range of -20 years to current year.
• Should not use a date-picker. I just want the year.
• Should be in HAML

select_tag "year", options_for_select(((Date.today.year - 20)..Date.today.year).to_a)

<%= select_tag "year", ((Date.today.year-20)..Date.today.year).map{|year| "<option>#{year}</option>"}.join.html_safe %>

We worked on this for a bit and (I also use HAML) the answer (I have accepted it) was

= select_tag "year", ((Date.today.year-20)..Date.today.year).map{|year| "<option>#{year}</option>".html_safe}
