I want to use observe_form to automatically save notes in a text_area.
This is the code I have:
<form id=''notes_form''>
<%= text_area :contact, :notes, :cols => 40, :rows => 10,
:id =>''notes_text_area'' %>
<%= observe_form(''notes_form'',
:frequency => 1,
:url => {:action =>
''update_notes'',
:contact_id => @contact.contact_id}) %>
</form>
For some reason, the contents of the text area are not being sent in the
post. In fact it doesn''t appear that the form is being serialized at
all. What am I doing wrong?

The api docs that describe the ":with" parameter to observe_field/form are cryptic, to say the least. After trying a number of semi-random strings I just now hit on a solution that seems to work: passing the string "value=value" as the :with param causes all of your form variables to show up in the POST params. I pass this on with the caveat that I haven''t the faintest idea why this works, and with no warranties that it won''t break in the future. hth, James -- James Hughes Web application developer Vancouver, BC "Developing a coherent political analysis is in many respects contingent upon an ability to connect one context to another, a process not dissimilar to playing the kid''s game of dot-to-dot." - Ward Churchill, from ''"A Government of Laws"?''
James, it has to be a bug. I just hard coded the javascript using the
prototype library as the observe_form function SHOULD do, and it works
fine:
//<![CDATA[
new Form.Observer(''notes_form'', 1,
function(element,
value)
{new
Ajax.Request(''/contacts/update_notes?contact_id=155'',
{asynchronous:true, evalScripts:true, parameters:
Form.serialize(''notes_form'')})})
//]]>

One thing I''ve been trying to get working is having the response to the form observer inject new input elements into the form, and then have those new elements be ''observed'' as well: no joy, though, it will only fire on events on form elements that were there when the form was first rendered. Thanks for pointing out the serialize method above; I thought it might help with this issue but no. I''ve hardcoded this snippet into my app as well.

I tried reporting it as a bug today, but the bugtracking system was unreachable... -Adam James Hughes wrote:> On 8/15/06, Adam Thorsen <adam.thorsen@gmail.com> wrote: >> Form.serialize(''notes_form'')})}) >> //]]> >> > > Yes, it''s definitely not working as advertised.
