How can I make a check box default to being “checked” in Rails 1.2.3?

Question

How can I make a check box default to being \"checked\" when it is initially displayed?

I\'ve not found a \"Rails\" way to do this (that works) so I did it with JavaScr

Answer 1

Rails 3.x

= form_for(@user) do |f|
  = f.check_box :subscribe, {checked: true, ...}

This sets the checked state to true and should work fine. Note the ruby 1.9.x syntax of the hash, for ruby 1.8.x use hash tag format {:checked => true, ...}
