Ajax and IE6 - is there some sort of "trick"?
Hi,
I''ve got some Ajax stuff that shows more or less of a complex form based
on a radio button selection. A "radio_handler" controller action is the
action for a form handler. Some seemingly simple "replace_html" fires
as a result of different radio buttons being chosen (which should then
show more or less of the form).
This all works just great on Mac Safari and

observe_field, does this generate HTML?
I don''t have Rails installed at the moment, I''d like to check myself,
but it''s just a simple curiosity.
observe_field fits into replacement tags <%= %>, which caught my
attention because as far as I know it''s just javascript observing a
field and should not stick anything into HTML. Is <%= merely used as an
enabling method, or will there actually be

I''m confused about how form verification with AJAX works. Let''s say I have a
''new.rhtml'' view that contains a form with two fields, and the form action is
''create''. Let''s assume that I also want to do some type of data validation on
one of the two fields via AJAX before I submit the form. But since I''ve

beginners question
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

bad move? - complex form with *many* observe_field's
I have a pretty complex form with many text fields and a number of
selects. We let the user add multiple types of associated objects to
the parent object and to edit the values for those associated objs, so
the form can have something like the following number of fields on the
page:
9 text fields + 3 selects + a*(1 text + 1 select) + b*(1 text + 1
select) + c*(1 text + 1 select) + d*(1 text +

Using RJS templates with observe_form
Hi there,
I''ve been checking out RJS templates, and have been trying to use them
with the observe_form helper.
However, the form values are no longer being passed in the params (as
soon as I point the action to the non-rjs and add the ''update'' clause
everything is working again). Is this expected?

Observing few fields in a form - Best Practise?
Hi,
im looking to build a page similar to a shopping cart page. When you
change the ''price'' or ''quantity'' fields, the total is calculated and
displayed.
There are other fields in the form which have no relation to this
action. So i guess observe_form is not required. Can someone tell me
what the best practise is for this?

on every field from the :update method for each field. i tried using

instance of the searchcontroller for its own.
I also tried using the :with => "something" on the definition of the
