How to set html_options for a 'select' helper in Ruby on Rails?

Question

I have the next code to display my countries table in a select box:

f.select("country_id",  Country.all.collect {|p| [ p.name, p.id ] }, {:include_blank => 'Select a Country'})

and i want to set an 'onchange' action when a country es selected... I've tried:

f.select("country_id",  Country.all.collect {|p| [ p.name, p.id ] }, {:include_blank => 'Select a Country',:onchange=>"alert('foo')"})

but nothing happens....

any help on this?

Thanks. Mr. Nizzle

Hi format of this helper is

select(object, method, choices, options = {}, html_options = {}) 

so try

f.select("country_id",  Country.all.collect {|p| [ p.name, p.id ] }, {:include_blank => 'Select a Country'},{:onchange=>"alert('foo')"})

and also check html output of your version
