[Rails] Realtime Form Validation Plugin Available
Granted, I''m still very much a newbie, but after reading an article on AJAX that basically states at one point that just because you can use AJAX doesn''t always mean you should, I have to ask: Why bother contacting the server (even if it is an insignificant amount of bandwidth) to validate the sanity of form data (unless you''re actually validating against something in the database)? Wouldn''t it be better to just wrap it up in the JS on the page? - Christian On 4/27/06 11:23 AM, "Vince Puzzella" <vpuz@rogers.com> wrote:> > Hi Folks, > I developed a realtime form validation plugin.

This uses your model validation code to validate the object. After that, it sends back javascript which modifies your dom. That enables you to mark/unmark fields that contain invalid data using css.

DRY ... Your model should already contain all the necessary validation code to ensure sanity in your DB. Using ajax means you don''t have to repeat/port all the validation rules to javascript. Granted, this means more requests to the server, but I''m willing to live with that if it results in a more responsive/livley interface.

Hi Vince,
I really want to use your plugin! really! Unfortunately after
installing and referencing it in my application, I get the following
error:

You might have expected an instance of Array.

From this message I assume that this has something to do with
multiparam handling, however, none of my fields shoudl require
multiparams, they are only simple textfields with numerical or text
values (i.e. I only have text_field tags in my view). I do have a
checkbox and a form submit button (with the checkbox specifying an
extra condition for the submit). Am I supposed to wrap these in span
tags like you describe on your homepage?`I referenced your plugin from
my controller and my view code like you described on your homepage. By
the way, I''m very convinced that these instructions should read
include UIEnhancements::RealtimeValidation
helper :RealtimeValidation
realtime_validation_for(:input_form, :contact_data_user_input)
right?
Any tips??
cheers

Maybe I should add that the javascript produced on my page is:
<script language="javascript">
new
Ajax.Request(''/webca/input/realtime_validation_for_input_form_contact_data_user_input'',
{asynchronous:true, evalScripts:true,
onComplete:function(request){eval(request.responseText)},
parameters:foo = Form.serialize(''input_form'')})
</script>
<script type="text/javascript">
//<![CDATA[
new Form.EventObserver(''input_form'', function(element, value)
{new
Ajax.Request(''/webca/input/realtime_validation_for_input_form_contact_data_user_input'',
{asynchronous:true, evalScripts:true,
onComplete:function(request){eval(request.responseText)},
parameters:foo = Form.serialize(''input_form'')})})
//]]>
</script>
Does this help?

Yihaa, I solved the problems! Thx Vince for your totally cool plugin!!! Here are the steps I had to perform in order to make it work 1) include UIEnhancements::RealtimeValidation helper :RealtimeValidation realtime_validation_for(:form_id_symbol, :model_symbol) instead of the lines shown on plugin homepage 2) give the controller instance variables (ActiveRecord objects) the same name as the model class they represent, i.e model :foo_data --> @foo_data 3) give all form_tag_helper methods an id named by modelnamewithoutunderscores_attribute_name_with_underscores Following these simple steps will let you ENJOY real time form validation! I love it :) Thx very much Vince!! cheers Martin On 5/29/06, Martin Gamsjaeger <gamsnjaga@gmail.com> wrote:> Maybe I should add that the javascript produced on my page is: > <script language="javascript"> > new Ajax.Request(''/webca/input/realtime_validation_for_input_form_contact_data_user_input'', > {asynchronous:true, evalScripts:true, > onComplete:function(request){eval(request.responseText)}, > parameters:foo = Form.serialize(''input_form'')}) > </script> > <script type="text/javascript"> > //<![CDATA[ > new Form.EventObserver(''input_form'', function(element, value) {new > Ajax.Request(''/webca/input/realtime_validation_for_input_form_contact_data_user_input'', > {asynchronous:true, evalScripts:true, > onComplete:function(request){eval(request.responseText)}, > parameters:foo = Form.serialize(''input_form'')})}) > //]]> > > </script> > > Does this help? > > On 5/29/06, Martin Gamsjaeger <gamsnjaga@gmail.com> wrote: > > Hi Vince, > > > > I really want to use your plugin! really!
