Rails - Feb 2008 - form options selections demystified...

Hi there,

I have a form which has a variety of fields and field types.  Each
field is presenting a unique challenge in understanding how the active
option is selected by default from data in the corresponding model.

In one instance, I have two radio buttons, "on" and "off." 
In the
controller, I load up the boolean value for the user''s settings from
the model user > notifications.

In the view I have the following:

<%= radio_button :user, :notifications, 1, :onclick =>
"Field.enable(''time''),
Field.enable(''period'')"  %> on
<%= radio_button :user, :notifications, 0, :onclick =>
"Field.disable(''time''),
Field.disable(''period'')" %> off

I''ve added :checked => checked to get a default option (so I know
that
works), but what I want is for the checked option to correspond to the
state in the model :user, :notifications.  How do i do this???

These form helpers I''m finding confusing for this.  Thanks for the
help.

-Alex

I prefer radio_button_tag.  For the third param, supply a method call to 
a function in the model that returns true or false depending on whether 
it should be selected or not.
