Rails spinoffs - Oct 2007 - Passing value such as record[colour] into new Ajax.Autocompleter(...) causes issues!

Hi Everyone,

After lots of research and development I got my Auto Complete working
with the Active Scaffold plugin
on a full _form.rhtml override.

I have one last problem that needs to be addressed.

I have an an element in the form like this.

####################################################################
<input type="text" value="<%= @record.colour %>"
size="15"
maxlength="15"  name="record[colour]"
id="record_colour"
class="colour-
input text-input" autocomplete="on"/>
####################################################################

Which conforms to the naming conventions of ActiveScaffold and sends
data through
upon create / update.
Just in case you are wondering I have to follow these attribute naming
conventions for the create/edit/update form to work. eg
name="record[colour]" id="record_colour"
I can not deviate at all otherwise the entire scaffolding system will
not work.

I also have a AutoComplete javascript function working but then it is
difficult to send through the "record[colour]" value with the AJAX
method.

Here is what the AJAX call looks like.

####################################################################
        <script type="text/javascript">
        //<![CDATA[
        var colour_results     new
Ajax.Autocompleter(''record[colour]'',
 
''colour_results'',
                                                        ''/products/
autocomplete'',
 
{method:''get''})
        //]]>
        </script>
####################################################################

It says then that the element does not exist and I know it is caused
by "record[colour]"
I have the following error.

####################################################################
this.element has no properties
baseInitialize("record[colour]", "colour_results",
Object)controls.js
(line 57)
initialize("record[colour]", "colour_results",
"/products/
autocomplete", Object)controls.js (line 402)
create()prototype.js (line 23)
evalScripts("\n//<![CDATA[\nnew
Autocompleter.Local(''record[colour]'',
\n ''colour_results'',\n
''/products/autocomp...")prototype.js (line 212)
collect("\n//<![CDATA[\nnew
Autocompleter.Local(''record[colour]'',\n
''colour_results'',\n ''/products/autocomp...",
1)prototype.js (line 367)
(no name)("\n//<![CDATA[\nnew
Autocompleter.Local(''record[colour]'',\n
''colour_results'',\n
''/products/autocomp...")prototype.js (line 328)
_each(function())prototype.js (line 541)
each(function())prototype.js (line 326)
collect(function())prototype.js (line 366)
evalScripts()prototype.js (line 212)
(no name)()prototype.js (line 1643)
[Break on this error] this.options.paramName = this.options.paramName
|| this.element.name;
####################################################################

It is caused by the naming convention of Active Scaffold.because if I
change the input tag for ...name="record[colour]"... to
this ...name="colour"... and the

AJAX call from "new Ajax.Autocompleter(''record[colour]'',
..." to "new
Ajax.Autocompleter(''colour'',..." then my auto complete
receives the
correct value and the drop down works but then the create/update does
not work as the input name attribute is not following AS conventions.

This might become a huge problem as any other AJAX calls follow the
same naming convention and will now not work.

Can anyone please help me or point out perhaps a mistake or better
way.

Is there a way basically to get "record[colour]" accepted by an AJAX
method,
as changing the name to "colour" won''t work with Active
Scaffold.

Thanks to anyone for any help.
I really appreciate it.

Uncle Mike
