hi group,
I am making a little rails app to experiment with rails. It consists
of one model, item, that represents an item on a todo list.
A todo item has a description, a state (finished or not) and a due
date.
After changing the scaffold screens a bit, I wanted to be able to
have no due date. I tried to do this by making a radio button; if 'no
date' is selected, the date selection field should be disabled.
I have something working now, but I have this feeling that it is not
exactly how it should be done in rails. Appended to this mail is my
app/views/item/edit.html.erb. Comments/suggestions welcome!
Especially the javascript part is bothering me: should it really be
included in the html.erb file and at that point? Another thing is the
radio_button_tags with the onclick. This is not good, is it?
thanks in advance, Ruud

edit.html.erb (hopefully the tags are preserved in the mail)

<script type='text/javascript'>

doc.getElementById( 'jid').disabled = noDate;
}
