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

I did it in that way.

Add hidden field with value 0 ABOVE check_box_tag

<%= hidden_field_tag :subscribe, '0' %>
<%= check_box_tag :subscribe, '1', params[:subscribe] != '0' %>

On server check with != '0'

subscribe = params[:subscribe] != '0'
