Thanks, Adam. With the debug line in the code, for
$person-affiliation_id, I get
[debug] Whats this -
AdventAjaxGrid2::Model::AdventAjaxGrid2DB::Affiliation=HASH(0xad06b00)
[debug] Whats this -
AdventAjaxGrid2::Model::AdventAjaxGrid2DB::Affiliation=HASH(0xad06a60)
[debug] Whats this -
AdventAjaxGrid2::Model::AdventAjaxGrid2DB::Affiliation=HASH(0xacff1e8)
[debug] Whats this -
AdventAjaxGrid2::Model::AdventAjaxGrid2DB::Affiliation=HASH(0xacff188)
[debug] Whats this -
AdventAjaxGrid2::Model::AdventAjaxGrid2DB::Affiliation=HASH(0xacff118)
If I change the debug line to get $person-name, it gives me the
following nicely:
[debug] Whats this - Jagdish Eashwar
[debug] Whats this - Sushama Marathe
[debug] Whats this - Manasi Jagdish
[debug] Whats this - Ninad Jagdish
[debug] Whats this - Muttsy
The name column has no belongs_to relationship, but the affiliation_id
column has. That must be making the difference.

push( @people, {

affiliation_id = $person-affiliation_id,
I would guess that this line is returning an Affiliation object rather
than the affiliation_id then? You could test it by adding this line
after the push
$c-log-debug('Whats this - '.$person-affiliation_id.\n);
if so then you would have to look at your Model.
Maybe someone with more experience could tell you the likely reason for
this?

Comment out console.log and see if that fixes your problem. Please
someone correct me if I'm wrong, but isn't that firebug only?

Hi,
No I don't get any javascript error in the error log when I hit 'save',
and it doesn't save the changes in the database either. Just nothing
happens.

Hi Peter,
Thanks for writing in. It is really not my code at all. I have taken it
all from the tutorial. I thought that people will get a better
perspective if I referred them to the tutorial. Nevertheless, I am
pasting code from the advent.js file below. ( I have made a few
inconsequential changes though, like the values in the drop down etc.)
/*
* advent.js
*/
Ext.onReady(function() {
var col_model = new Ext.grid.ColumnModel([
{
id: 'id',
header: 'ID',
dataIndex: 'id',
width: 40
},
{
id: 'name',
header: 'Name',
dataIndex: 'name',
editor: new Ext.form.TextField({
allowBlank: false,
})
},
{
id: 'occupation',
header: 'Occupation',

editor: new Ext.form.ComboBox({
typeAhead: true,

})
}
]);
col_model.defaultSortable = true;
var People = Ext.data.Record.create([
{ name:'id',type: 'int'},
{ name: 'name',type: 'string'},
{ name: 'occupation',type: 'string'}
]);
var store = new Ext.data.JsonStore({
url: gridurl,
root: 'people',
fields: People
});
var grid = new Ext.grid.EditorGridPanel({
store: store,
cm: col_model,
title: 'Edit Persons',
width: 600,
height: 300,
frame: true,
autoExpandColumn: 'name',
renderTo: 'datagrid',
tbar: [
{
text: 'New Person',
handler:function() {
var p = new People({
name: 'Unnamed New Person',
occupation:'Unknown',
});
grid.stopEditing();
store.insert( 0, p );
grid.startEditing( 0, 1 );
},
},
{
text: 'Save Changes',
handler:function() {
grid.stopEditing();
var changes = new Array();
var dirty = store.getModifiedRecords();
for ( var i = 0 ; i dirty.length ; i++ ) {
var id = dirty[i].get( 'id' );
var fields = dirty[i].getChanges();
fields.id = dirty[i].get( 'id' );
changes.push( fields );
}
console.log( changes );
submitChanges( changes );
store.commitChanges();
},
},
{
text: 'Discard Changes',
handler:function() {
grid.stopEditing();
store.rejectChanges();
},
}
]
});
store.load();
function submitChanges( data ) {
Ext.Ajax.request({
url:posturl,
success:function() { store.reload() },
params: { changes: Ext.util.JSON.encode( data ) }
});
}
});
gridurl and posturl are defined in index.tt2 pasted below. It also
contains a link to advent.js.
[% META title = 'Advent AJAX Grid' %]
script type = text/javascript
var posturl = '[% Catalyst.uri_for(/people_data_submit) %]';
var gridurl = '[% Catalyst.uri_for(/people_data) %]';
/script
[% js_link (src = '/static/advent.js') %]
div id = datagrid/div

No, don't do that!
Use $row-get_columns which returns a hash of the column data!
Accessing internal methods is bad, accessing internal hash keys is
doubleplusungood. If you find yourself doing that, go read some
documentation. If you haven't figured it out without doing that,
submit a patch for a proper method!
Here's the pod:
http://search.cpan.org/~ribasushi/DBIx-Class-
0.08012/lib/DBIx/Class/Row.pm#get_columns
Also, you can use the HashRefInflator which works -fantastic- for
JSON views:
The code is very simple:
my $rs = $c-model('DB::Books');
$rs-resultclass('DBIx::Class::HashRefInflator');
$c-stash-{books} = [ $rs-all ];
You can read about that here:
http://search.cpan.org/~ash/DBIx-Class-
0.08010/lib/DBIx/Class/ResultClass/HashRefInflator.pm
excellent, thanks guys, with minor modifications both those approaches
work:
$c-stash-{books} = [map { $_-get_columns } $c-
model('DB::Books')-all];
OR:
my $rs = $c-model('DB::Books');
$rs-result_class('DBIx::Class::ResultClass::HashRefInflator');
$c-stash-{books} = [ $rs-all ];
thanks again for your help
adam
You only want to present the data you need to ExtJS, you were stuffing
the whole dbic resultset object into the JSON ;).

RE: [Catalyst] Catalyst - any good AJAX tutes?
I second that ExtJS recommendation. The user community is pretty good from a support point of view. Once you get the hang of it, it's really easy to do a lot of neat things with it. -Original Message- From: Alexander Hartmaier [mailto:alexander.hartma...@t-systems.at] Sent: Friday, March 06, 2009 12:14 PM To: The elegant MVC web framework Subject: Re: [Catalyst] Catalyst - any good AJAX tutes? I'd suggest ExtJS if you want something pretty good looking with great out-of-the-box features or YUI/jQuery if you like to stick with JS-enhanced HTML. The Dojo features + docs sucked *very* much when I used it about a year ago... On the Catalyst side I use Catalyst::Controller::DBIC::API which will support the full DBIC API for searches, pagination and prefetch in the next version which should be on CPAN in 2-4 weeks if lukes and I find time to finish it. trunk already contains my json-style search and pagination patches but lacks prefetch support cause we need to find a way to restrict/validate the user input to prevent huge queries killing the DB and/or revealing data that shouldn't be revealed.
