I don't quite see the point of this. Why not just add methods to MyApp.pm? (I'm guessing there might actually be a sane reason for you not wanting to do it this way, but I can't grok what it is) Ash Mainly, because there is no automated, programmatic way to add plug ins to a generated Cat app without editing code. The scenario is: mango.pl MyApp which in turn, uses $helper-mk_app, just like catalyst.pl MyApp does. After that point, my scripts can add models, view and controllers just dandy, but there's no way to add plugins unless I literally open MyApp.pm in the script, and do: s/ ConfigLoader StaticSimple / ConfigLoader MyApp::Plugin::Foo OtherApp::Plugin::Bar Static::Simple / That's nasty at best and will fail eventually when the defaults change. I can add models/view/controllers by dropping files in the correct directories, why not plugins? Aside from Mango, anyone who generates Cat based apps automatically when accounts are created (like virtual hosts...MediaTemple) may want or need to also install default plugins. Just dorpping them in a Plugins directory just like M/V/C makes more sens than trying to automatically edit code in my book. -=Chris signature.asc Description: OpenPGP digital signature ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/[EMAIL PROTECTED]/ Dev site: http://dev.catalyst.perl.org/

Andrew
Hi,
I am unable to keep up with the discussion.
When I use @role_id = $c-req-param(role_id) as Andrew suggested, I am
getting an error in Catalyst saying Can't use string (4) as a HASH ref
while strict refs in use. 4 is one of the values that the code is
fetching.
So I changed the code to read @role_id = $c-req-params(role_id) as
Kevin suggested and put [EMAIL PROTECTED] in the stash. Now there was no
error, but
I got ARRAY(0x987e5e0) in the template instead of the role_id values.
So I further changed the code to $role_id = $c-req-params(role_id) and
put $values in the stash. Now I could access in the template the multiple
role_ids that the code was picking up. I realised then that I pick up single
values also in the same way.
So is the way for picking up multiple values the same as for picking up
single values?
Moving on from here, I want to pick up the corresponding role descriptions
for each role_id from a database table and show role descriptions rather
than the role_id's in the template.
When I am picking up only a single role_id, I am able to achieve this by
using
my @role_desc = $c-model('myleavedb::role_types')-find($role_id)
and putting [EMAIL PROTECTED] in the stash.
I am unable to figure out how the coding is to be done when I retrieve
multiple role_id's.
I tried looping over the multiple role_ids in the arrayref ($role_id), but
couldn't get the code right.

I like both approaches, see advantages and the lack of mutual exclusiveness, but I'm wondering now about the syntax and the potential for confusion with new users. --john ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/[EMAIL PROTECTED]/ Dev site: http://dev.catalyst.perl.org/ Be a better friend, newshound, and know-it-all with Yahoo!

[Catalyst] upload breakage
Hi folks:
I am trying to set up a simple multiple upload form. Using jQuery
multi class for the interface portion. The form looks like this:
form action=/upload class=multi enctype=multipart/form-data
input type=file class=multi /
input type=submit name=upload value=upload file(s) /
input type=hidden name=destination_path value=%
$destination_path % /
input type=hidden name=form_submit value=yes /
/form
and the receiving action is basically a cut and paste from the cookbook
my $path = $c-req-param('destination_path');
$c-log-debug('* path = '.$path);
if ( $c-request-parameters-{form_submit} eq 'yes' ) {
$c-log-debug('* uploading! ');
for my $field ( $c-request-upload ) {
$c-log-debug('*** field '.$field);
my $upload = $c-request-upload($field);
my $filename = $upload-filename;
my $target = File::Spec-catfile($path,$filename);
$c-log-debug('*** name '.$filename);
$c-log-debug('*** target'.$target);
unless ( $upload-link_to($target) ||
$upload-copy_to($target) ) {
die( Failed to copy '$filename' to '$target': $! );
}
}
}
Now when I try to upload a file, in this case a simple perl script named
wireless.pl ... fairly small as a simple test case, the controller reports
[debug] Query Parameters are:
.-+--.
| Parameter | Value
|
+-+--+
| destination_path| /tmp
|
| file| wireless.pl
|
| file1 |
|
| form_submit | yes
|
| upload | upload file(s)
|
'-+--'
[debug] GET request for upload from 127.0.0.1
[debug] Path is upload
[debug] * path = /tmp
[debug] * uploading!
[debug] * dump = $VAR1 = 'upload file(s)';
but it never seems to hit the innards of the loop. So it doesn't
actually go through extracting the file name and so on.
Any clues? Is it obvious what I am doing wrong here?
And if there is a better way to do multi file upload using Catalyst and
jQuery, please, by all means, I am all ears ...
Thanks!

[Catalyst] DBIC ResultSet - what columns in it?
I was looking for a way to get column names from a ResultSet.
If I have a table with columns id, to, from, subject which is mapped
into Email then if I do
$c-model('Email')-{_source_handle}{schema}{source_registrations}{Reuniao}{_ordered_columns}
then I get [ qw/ id to from subject / ] indeed, but it would be nice to
have a simpler method to get there.

Just to keep the conversation rolling, let's put aside the Plugins
directory for the moment.
If you wanted to load plugins from config, what would you like to see?
What would you need?
1. Load all plugins specifically from config, ignoring what's in
MyApp.pm when specified?
plugins:
- ConfigLoader
- Session
- Session::State::Cookie
- Session::Store::File
- +MyApp::Plugin::Frobnisicate
- Static::Simple
++;
but ConfigLoader need to load config?
generally we can do something like:
# MyApp.pm
use Catalyst qw/ConfigLoader/;
__PACKAGE__-setup(); # this would load __PACKAGE__-config;
if ( __PACKAGE__-config-{plugins} ) {
__PACKAGE__-setup_plugins( __PACKAGE__-config-{plugins} );
}
that's it I think.
2. Load plugins from a location?
plugins:
path: __path_to(lib, MyApp, Plugins)
3. Prepend/Append plugins to be loaded around MyApp.pm?
plugins:
prepend:
- Debug
append:
- Static::Simple
- +MyApp::Plugin::Foo
