how to build a select tag from a range in rails

Question

I want to have a drop down that consists of values 10% 20% 30% so on till 100.

In ruby It can be done by

(10..100).step(10) { |i| p i }

Answer 1

Without Providing a Formatted Value.

If you landed here, like me, without the need to use step() or to provide a formatted value (e.g. "20%"), this is a nice and succinct method:

<%= f.select :year, (2011..Date.today.year).to_a %>


  2011
  2012
  2013
  2014
  2015

With a Default

<%= f.select :year, options_for_select( (2011..Date.today.year).to_a, Date.today.year ) %>


  2011
  2012
  2013
  2014
  2015
