[Catalyst] error "Objects supplied as 'foreign_values' usually should inherit from the related ResultClass"
This is a weird one.
Short version:
$userexam->user is defined as Auth::User, but seems like it gets redefined
as DB::User somewhere mysteriously.
How can I track that down?
Long version:
Split database setup: DB is for the application data, Auth is for user data.
The userexam table links users to the exams they take.
*Schema/DB/Result/UserExam.pm
*contains:
__PACKAGE__->belongs_to( user => 'Learn::Schema::Auth::Result::User' );
__PACKAGE__->belongs_to( exam => 'Learn::Schema::DB::Result::Exam' );

sub take { # take the exam
my $rs = shift; # Learn::Schema::DB::ResultSet::UserExam object
my $user= shift; # Learn::Model::Auth::User object
my $exam= shift; # Learn::Model::DB::Exam object
...
my $user_exam = $rs->create({
user => $user,
exam => $exam,
});
}
The error it throws at $rs->create() is:
*DBIx::Class::ResultSource::_resolve_relationship_condition(): *
*Objects supplied as 'foreign_values'
(Learn::Model::Auth::User=HASH(0xe022b14)) *
*usually should inherit from the related ResultClass

*perhaps you've made a mistake invoking the condition resolver? *
In the schema file
,
->user is defined as Auth::User. Somehow it gets redefined along the way
and Catalyst thin
k
s it should be DB::User instead?!
Grepping for DB.*User (and variations) in schema files brings up
DB::UserExams and related info (DB::UserCourse, DB::UserRole,
DB::UserAnswer) but no DB::User at all.
How could that get redefined? Or is this a symptom of something else? I
could use a big clue stick upside the head :/
Thanks!

[Catalyst] Using and inter-linking multiple databases: Can't find source
In our app we have two databases: Auth and DB. The generalized user/team credentials and related info are in Auth, and the actual business info for this app is in DB. Here's an object from the DB database: package Learn::Schema::DB::Result::TeamEmail; #... __PACKAGE__-belongs_to( team = 'Learn::Schema::Auth::Result::Team' ); And now the related object from the Auth database: package Learn::Schema::Auth::Result::Team; #... __PACKAGE__-has_many( emails = 'Learn::Schema::DB::Result::TeamEmail', 'team' ); At this point we expect *$team-emails_rs* to work but instead we get Can't find source for Learn::Schema::DB::Result::TeamEmail because TeamEmail isn't in $self-source_registrations (full names) or $self-class_mappings (brief names) in the DBIx::Class::Schema::source() method.

[Catalyst] Re: Simple session snag probably -- Couldn't find a model named Learn::Session
Ah thanks for the clue-stick :) Hailin -- We had messed up on the CREATE phase in getting the Schema set up, and it was the two-schema approach that tripped us cuz we weren't paying attention: script/learn_create.pl model DB DBIC::Schema Learn::Schema::DB create=static dbi:mysql:learn user pw script/learn_create.pl model DB DBIC::Schema Learn::Schema::Auth create=static dbi:mysql:auth user pw Those are the two commands we had issued to create the model. Whoops! The first was okay but the second used the exact same second-argument and shouldn't have. That is, the second command overwrote the first instance under Learn::Model::DB. The following fixed it: script/learn_create.pl model DB DBIC::Schema Learn::Schema::DB create=static dbi:mysql:learn user pw script/learn_create.pl model Auth DBIC::Schema Learn::Schema::Auth create=static dbi:mysql:auth user pw Changing DB to Auth in the second arg, and now all is well. Thanks! On Sunday, August 11, 2013, Hailin Hu wrote: How is your model like? I suppose you map your schema and model as below: Learn::Schema::Auth - Learn::Model::Auth Then Auth::Session should work.

At first we thought maybe the script formats had changed. So we ran a
quick sample catalyst.pl Catalyst::Upgrade to come up with the latest
structure for comparison. This I'll call new script below. Then we looked
at the script/*pl files, the lib/* files. None of the structures seem to
have changed from what we can tell.
That is, the old script/*server.pl script has the same standard
structure as the brand new script:
#!/usr/bin/env perl
BEGIN {
$ENV{CATALYST_SCRIPT_GEN} = 40;
}
use Catalyst::ScriptRunner;
Catalyst::ScriptRunner-run('Waste::Web', 'Server');
1;
Comparing lib/Waste/Web.pm (old script) to lib/Catalyst/Upgrade.pm (new
script) also looks similar -- commented code redacted for space:
package Waste::Web;
use Moose;
use namespace::autoclean;
use Catalyst::Runtime 5.80;
use Catalyst qw/
ConfigLoader
Static::Simple
Session
Session::Store::DBIC
Session::State::Cookie
Authentication
Authentication::Credential::Password
Authorization::Roles
Cache
/;
use Waste::Lib::CSV;
extends 'Catalyst';
our $VERSION = '1.10';
__PACKAGE__-config(
name = 'Waste::Web',
# Disable deprecated behavior needed by old applications
disable_component_resolution_regex_fallback = 1,
);
# Start the application
__PACKAGE__-setup();
In the new script there *is* a new option to the __PACKAGE__-config
call but it's just to instantiate the X-Catalyst http header. All serious
structures look the same.
But Catalyst::Upgrade runs just fine, and an old app Spill runs

At first we thought maybe the script formats had changed. So we ran a
quick sample catalyst.pl Catalyst::Upgrade to come up with the latest
structure for comparison. This I'll call new script below. Then we looked
at the script/*pl files, the lib/* files. None of the structures seem to
have changed from what we can tell.
That is, the old script/*server.pl script has the same standard structure
as the brand new script:
#!/usr/bin/env perl

use Catalyst::ScriptRunner;

Catalyst::Plugin::Session::Store::DBIC
[Catalyst] sub-modules for model
Spent a bit of time googlilng this and apparnelty I'm not searching very
effectively today...
Short version:
What's best-practices to get model library sub-modules hooked in to the
main model?
Long version:
*catalyst.pl Thingy*
*cd Thingy*
*script/thingy_create.pl model DB DBIC::Schema \*
* Thingy::Schema::DB create=static dbi:mysql:thingy \
*
* dbuser dbpasswd*
So now we have lib/Thingy/Model/DB like so:
*package Thingy::Model::DB;*
*
*
*use strict;*
*use base 'Catalyst::Model::DBIC::Schema';*
*
*
*__PACKAGE__-config(*
*schema_class = 'Thingy::Schema::DB',*
* *
*connect_info = {*
*dsn = 'dbi:mysql:thingy',*
*user = 'dbuser',*
*password = 'dbpasswd',*
*}*
*);*
This is a top-level module. Instead of a monolithic mess with all possible
library routines in one package, we want to modularize sub-functions into,
say
*Thingy::Model::DB::Team*
*Thingy::Model::DB::User*
*Thingy::Model::DB::Incident*
etc
Do we have those sub-modules use the top-level Thingy::Model::DB? Do we
have Thingy::Model::DB use the sub-modules?
Do we have the sub-modules use base 'Catalyst::Model::DBIC::Schema'? Or
can they just extends 'Catalyst::Model' and if so how do they hook in
with $c?
Is there an elegant way to have all the sub-module models use the same DB
config as the top model?
...or...
What's the best practice for getting separate modules to work as models in
the MVC universe?

All independent requests -- someone may bookmark page 2 and go back there
directly.
Then (later) think about caching. That depends on usage, your database
load, your SLA, your traffic, load, etc. You could fetch the entire result
list on the first request and cache, for example, or you could instead
cache the entire page (with a separate page cache layer).
Use a cache, not the session, for caching. There's nothing here related
to the session unless you wan to display something like recent searches
to show on all pages -- and even that might be better in the cache keyed by
user's ID if users are required to log in.

We pack our config (which basically is a big hash) in a class. To
provide the config to Catalyst, we use the class in my_app.pl (which is
like my_app.(yml|json|ini|...). If we need the config in some other
scripts, we just use the class there.
The non-Web code lives in classes (eg DBIC) that are used via Models in

in other contexts.

Re: [Catalyst] Changing Formhandler field-type/widget based on Catalyst user-role
Hmm. Still puzzled as to what solution might work with that approach. Maybe changing-field-type is philosophically questionable, but the mechanism still looks like it should work. :) But didn't. So we're off to try more FormHandler magic from a different angle (not catalyst-affected, so we're posting on the formhandler list for that).

Short answer; don't. If you're maintaining the value for users who aren't allowed to change it, then you don't want it in your form data. Form submissions can be spoofed, so you'd have to double-check the value (or drop it) in your Perl code anyway... so you might as well just do that, and remove it entirely from the HTML (which seems to be a simpler problem?)

[Catalyst] Changing Formhandler field-type/widget based on Catalyst user-role
Short version: How can we toggle field X from being a Select (popup) for
Admin users, to being a Hidden (nothing visible, but the value is
maintained) for Manager users?
Long version:
We have three levels of user-roles (*admins* can do everything,
*managers*can do a lot,
*readonly* can do very little). Admins get to specify user roles for all
users (even other admins), but managers (level two) only get to edit
readonly users and we don't want them to elevate any such users to being
managers (or worse, admins).
package MyApp::Controller::Admin::Person;
#...
$self-form( MyApp::Form::Admin::Person-new( ctx = $c ) );
package MyApp::Form::Admin::Person;
#
sub set_active {
my $self = shift;
$self-inactive(['role'])
unless $self-ctx-user-is_admin;
}
Trying to use ctx so we could pass $c and later test it in the form's
set_active method throws an exception because of ctx being undefined.
package MyApp::Controller::Admin::Person;
#...
unless ( $c-user-is_admin ) {
# $self-form-inactive(['role']);
# $self-form-field('role')-widget('hidden');
# $self-form-field('role')-type('Hidden');
}
So instead we've tried making the field inactive (no apparent effect at
all), switching to a different widget (field completely disappears) or
different type (field completely disappears).
Pointers?

Re: [Catalyst] No data showing

I'd recommend that you look into iterating thru the recordset in the
template, instead of rendering all rows of data before it's rendered:
my $acct_rs =
$c-model('ORANGE::AccountView')-*search_rshttp://search.cpan.org/~arodland/DBIx-Class-0.08196/lib/DBIx/Class/ResultSet.pm#search_rs
*(
{},
{
order_by = 'account_code',
page = $page_no,
rows = $rows_per_page,
},
);
$c-stash( accounts = $acct_rs );
then in your template
[% WHILE ( acct = accounts.next ) %]

Maybe I'm being thick, but where does that instance of MyApp come from?
I don't see it being passed into FCGI::ProcManager
What instance of MyApp?
MyApp-method() is a direct reference to the original package, not to an
instance.
my $myapp = MyApp-instantiate() would be an instance, if you had such a
method to call.
use MyApp;
MyApp-something();
MyApp has been included as a library, so now you can call it appropriately.
There's *no instance* in this case...
the one that I'm going to call -model() on in order to pre-connect to my

There is no instance?
Then there's some magic that I'm missing? If I take your code literally,
I'm going to get a 'cannot use a string as a hash ref' error.

Re: [Catalyst] Catalyst generating emails -- how to buffer large attachments?
Thanks for the pointer, t0m!
We switched to Mail::Sender -- it opens a connection to the SMTP server
immediately, and pipes the output generating on -the-fly, instead of
accumulating beaucoup megabytes in RAM to then ship off the whole thing at
once.
Wound up doing as you suggested:
use base 'Catalyst::View::TT';
use Email::MIME;
use Mail::Sender; # = woo hoo!
use Moose;
sub render { ... }
And within render() we purloined chunks of the templating approach
(generate_part) from Catalyst::View::Email::Template in order to still use
the templates approach (one for HTML, one for text).
Works a treat!

Yes, in the view code :_)
But you don't mean this, you mean 'in Catalyst::View::Email'
If we could use a combination of Template-Toolkit and Email::Stuff which
handles buffering nicely (hand it a $FH instead of content, swee-ee-eet)
that would be grand. It doesn't look like Email::MIME (which
Catalyst::View::Email builds upon) doesn't seem to expect anything other
than $body_content.
Time to not be using Catalyst::View::EMail then :)
I'd recommend just sub-classing either your existing (or a new) TT view,
and using around render = sub {... to do whatever you want with
Email::Stuff, taking the document you've just rendered with TT, and the
other attachments and doing the right thing.
Cheers

[Catalyst] Catalyst generating emails -- how to buffer large attachments?
Using Catalyst::View::Email::Template is great for separating presentation
from data in generating emails, but we're running into Server issues when
the email includes a large attachment (or several). The whole email gets
built in server ram before the response comes back to the browser.
Is there a (straightforward, hopefully :) way to buffer large attachments
when generating emails via a Catalyst View?
$att = $item-attachments_rs;
if ( $att-count ) {
my @parts;
require Email::MIME;
while ( my $fyl = $att-next ) {
my $part = Email::MIME-create(
attributes = {
filename = $fyl-path,
name = $fyl-path,
content_type = $fyl-mimetype,
disposition = 'attachment',
encoding = 'base64',
},
# body = read_entire_file( *$fyl-path_to_file* ), # ugh!
*body = $fyl-path_to_file, # or $filehandle*
);
push @parts, $part;
}
$email_args{parts} = [ @parts ];
}
$c-stash( email = { %email_args } );
$c-forward( 'View::Email' );
If we could use a combination of Template-Toolkit and Email::Stuff which

that would be grand. It doesn't look like Email::MIME (which

[Catalyst] Overriding content-type for View::JSON
Short version: what's the protocol in a MyApp::View::Blah to override
content-type in certain circumstances?
Long version:
We're trying to get the blueimp file-upload jQuery library working under IE
(fine under firefox and chrome, of course):
https://github.com/blueimp/jQuery-File-Upload/wiki/Setup
The recommendation is that the server should set content-type to text/html
or text/plain instead of application/json for IE. Here's the PHP example
they post:
?php
header('Vary: Accept');
if (isset($_SERVER['HTTP_ACCEPT'])
(strpos($_SERVER['HTTP_ACCEPT'], 'application/json') !== false)) {
header('Content-type: application/json');
} else {
header('Content-type: text/plain');
}
?
What's required in MyApp::View::JSON to handle this properly?

Re: [Catalyst] Dealing with timestamps from Postgres
Catalyst sure is wide and deep. One can get a reasonably advanced app running in Catalyst without knowing broad stretches of what goes on, or *can* go on, under the hood. There's so much possible, and so many handy methods and plugins that you're gonna A) overlook things on the mad dash to the goal or B) not understand the value of things until much later (like abstracting code to a library, it often takes a few iterations before the utility becomes obvious). This case was a combination of both. I often struggle to find the answer to a has someone else solved this already question, and wind up rolling my own solution... only to run in to someone else's cleverer, cleaner approaches later (often by accident). In order to have 'perfect documentation' it must meet two criteria: A) explain the utility and usage (benefits and how-to) *in a way that I can grok* and B) show up on my radar *in my searches*. Both of these depend a helluva lot on my own activity and context, making compliance impossible. :) Sometimes scar tissue is the only (best?) way to really learn.

[Catalyst] Paradigm question: how to use ResultSet level security based on $c-user?
Question: when a user logs in to our Catalyst app, he/she should only see
the items he/she is allowed to see. But the only way we can figure how to do
this is to pass $c-user either to the ResultSet methods or to the
FormHandler methods, making the app more and more interdependent... Is there
a better paradigm in the context of a Catalyst app?
Right now we're working this via DBIC ResultSet like so:
package Incident::Schema::DB::ResultSet::Incident;
use base 'DBIx::Class::ResultSet';
sub *security* {
my $rs = shift;
my $user= shift;
$user = $user-obj
if ( $user-can('obj') );
if ( $user-is_admin ) {
return $rs; # everything is visible to admins
}
my %visible_teams = map { $_ = 1 }
$user-corp_team_ids; # method from Incident::User schema
$rs = $rs-search(
{ 'me.team' =
{ -in = [ keys %visible_teams ] }
},
{ order_by = ['created'] }
);
return $rs;
}
Then...
package Incident::Web::Controller::Ticket;
BEGIN { extends 'Catalyst::Controller'; }
sub base : Chained('/auth') PathPart('ticket') CaptureArgs(0) {
my ( $self, $c ) = @_;
my $rs = $c-model('Incident::Ticket')-security( *$c-user* );
$c-stash( incident_rs = $rs );
}
Is this Kosher? In this context it's a DBIC resultset depending on another
DBIC object, so it may not be as big an issue as, say, when we have
HTML::FormHandler popup menus that should only show the user options based
on the user's role and/or organization.
Is there a canonical way to approach this both in ResultSets and in
FormHandler forms?

Re: [Catalyst] Using URL for /search/parameters: bad idea?
When the search-screen has a dozen or more fields (client requirements),
it's more likely that we use a POST instead of a GET. Bookmarking THAT ain't
so easy.
So instead of reiterating the original question, let me ask a related
question:
What's a good way to cache a search (so the user can page-up/page-down)? Can
we just
$c-session( search_rs = $rs-search({%params}) )
I imagine that would take up a lot of space in the session record, but maybe
that's not much of a consideration...
...or is there a straightforward way to serialize the search parameters?
What's the consensus on this?

Re: [Catalyst] Re: Trying out FormHandler, running into maketext error
Discovered something about FormHandler's form_generator.pl... The auto-generated FormHandler code (via *form_generator.pl*) creates submit buttons like this: has_field 'submit' = ( *widget* = '*submit*' ); but that leads to the original error undef error - Unable to do maketext on: at /usr/local/share/perl/5.10.0/HTML/FormHandler/I18N.pm line 15 Apparently it should generate the following code instead? has_field 'submit' = ( *type *= '*Submit*' ); That fixes the I18N errors, and it actually works to produce a submit button. (Note that type is used instead of widget and Submit is capitalized instead of submit.) Is this a canonical goof in form_generator.pl? Or is there something missing in my environment that's interfering?

Mwa ha ha! It was $c-SET_AUTHENTICATED all along! This is how you
switch-user/become-user/super-user inside Catalyst.
Try this on for size:
sub su : Chained('/is_admin') PathPart('su') Args(1) {
my ( $self, $c, $id ) = @_;
my $user_was = $c-user;
my $user_is = $c-find_user({ id = $id }); # Do some error trapping of

$c-*set_authenticated*( $user_is );
$c-stash( message = join ' ', 'Switched

Voila! Now $c-user is $user_is and no longer $user_was. Neat!

I don't know that there is a canonical way. This is Perl.
As I mentioned in my reply to this thread in July[0], one way is to
login as the new user and store the original username in the new user's
session. That way the app knows that the new user is allowed to revert
to the original user, but otherwise the app treats the current session
just as it would if the new user had logged in normally.

My question is similar -- why five thousand or more calls for rendering one

my $form = $self-form;

# change any $1,234 to 1234, parse 12-apr-09 to a date 2009-04-12, etc

params = $c-req-params,
);
if ( $form-has_errors) { ... }
return unless $processed;
# since we're testing rendering a fresh page there's no processing, that's
it
So why would this simple code generate 5,000+ calls to SQL::Abstract methods
or to DBIx::Class::Resultset methods? Even commenting-out
#parse_form_for_numerics()
it's about the same. Still looking into this.

[Catalyst] Caching SQL results for speed...?
Mostly thinking out loud here... but we welcome feedback if we're off
track...
Okay, after some perl -D:NTYProf tester.pl with 200 iterations:
70% of the time is taken up in five modules:
1) SQL::Abstract
2) DBIx::Class::ResultSet
3) Class::Accessor::Grouped
4) DBIx::Class::Storage::DBI
5) HTML::FormHandler::Field
...because in 200 iterations they were called millions of times each. (The
form requested has several select/option menus.)
Most of the data won't change rapidly -- e.g. client lists, countries,
employees just to populate a few popup menus -- so it seems like an
opportunity to benefit from caching the results, and only invalidating the
cache when a new record gets updated/deleted/added. Whole tables could be
cached without having to return to SQL/DBIC for every form-screen.
So we're looking for documentation on a best-of-breed approach for doing
this in a Catalyst environment...
Looking at Catalyst::TraitFor::Model::DBIC::Schema::Caching it looks like
you specify when the cache will expire:
$c-model('DB::Table')-search({ foo = 'bar' }, { cache_for = 18000 });
whereas we would prefer being able to invalidate-cache-for-table-XYZ-now.
Aha, DBIx::Class::Cursor::Cached does include a
$rs-cursor-clear_cache;
method, we'll be tinkering with that, next!

Maybe it is blocking on DNS network lookups.
Or if the time isused around the database calls, run with DBIC_TRACE=1

Re: [Catalyst] Requesting example code for postfix and Email::Sender
You're probably overthinking this. :)
Whether it's postfix or exim or any other daemon really shouldn't matter.
Your code will connect to SMTP server localhost on port 25. If you can
send an email from the command line (via 'mutt' or 'mail' etc) then you
should be ready to go:
First
$ *script/myapp_create.pl view Email Email*
Then
#myapp.conf
View::Email
stash_key= *email*
default
content_type = text/plain
charset = utf-8
/default
/View::Email
Then in a controller...
$c-stash-{*email*} = {
from = $c-config-{email_from},
'reply-to' = $c-user-email_name,
to = $c-user-email_name,
cc = join(',', @cc),
subject= $subj,
body = $message,
};
$c-forward( $c-view('Email') );
Note on the manpage (below) that it will default to LOCALHOST and SMTP
unless you specify otherwise

Re: [Catalyst] Where are my modules?
If you did a force-install at some point in the past, e.g. to get Catalyst::Plugin::ConfigLoader installed, then you may have skipped some dependencies. Wiser folks than me can probably tell you how to get CPAN to recover to a more stable state, but it sounds like you'll have to follow the dependency chain by hand until then. That is, each missing module will require you to do a cpan Mod::Here to get it up to snuff. You may be doing this already, but if you use lib::local instead of your system perl libraries as root (or via sudo) then A) you won't break your system perl, 2) you won't need root permissions to update your library and 3) if the muses smile at you just right you might be able to migrate your whole cpan library to a new system when the time comes, with a simple file-copy. http://perl.jonallen.info/writing/articles/install-perl-modules-without-root Something we're running into is when Cpan module dependencies don't work out right, after migrating a project to a new system. Instead of being up and running in a matter of minutes (or hours if lots of compiling is needed) it's turning into a matter of days, sometimes weeks, to get all the dependencies straightened out. :( On Thu, Mar 17, 2011 at 4:24 AM, Carl Franks fireart...@gmail.com wrote: On 17 March 2011 09:06, John M.

No, normally only the `make install` step of each dist needs elevated privileges. If distributions try to create directories in system locations during other steps, then this is a bug. Probably you've already run this as root (or via sudo) and paths have been created with root ownership. Your normal user isn't allowed to frob those.

Re: [Catalyst] Root page for site (my first attempt!)
In your main lib/MyApp.pm file you'll probably notice you've got a line of
code like
use Catalyst qw/ ... Static::Simple .../;
That pulls in Catalyst::Plugin::Static::Simple which does the part you're
asking about.
See
http://search.cpan.org/~mstrout/Catalyst-Plugin-Static-Simple-0.29/lib/Catalyst/Plugin/Static/Simple.pm
for
tricks on configuring it to do your bidding.
Also, when running under a webserver such as Apache, you'd likely do some
configuring there to have the webserver send the static files directly
instead of calling on Catalyst to parse through them.
E.g.
http://search.cpan.org/dist/Catalyst-Runtime/lib/Catalyst/Engine/FastCGI.pm#Static_mode

And of course, it is recommended to configure the web server to not send

That's exactly what I want. How do I tell Catalyst that /images should be
static files under /root/images, rather than a controller named Images?
And as Carl recommended, it is good to not hard-code the URLS in the
templates because they won't work if you'll want to make some changes and
want to put the whole application to listen to a different base than /, for
example /old-site.
So use $c-uri_for('/path/to/static/file');
or
$c-uri_for_action('/path/to/action'); #for the dynamic pages
I see, so do that for static files too, not just actions?

Nope it's not the javascript. Searching view-source for http://; shows only DOCTYPE, xmlns, !-- comments -- and links to other/external websites.

Re: [Catalyst] Re: Making secure session cookies (or, how do we make Explorer stop complaining about nonsecure content on a secure page?)
Okay -- we'd tried this approach using Chrome already, and it is not showing
*any* http:// requests from the https:// page.
Life HTTP Headers (FireFox) shows either https://server.name/path requests
or server-relative /path requests. Period.
Same url, yet internet explorer complains... I've got a knack for finding
weird stuff like this. Anybody else seen this?

Another nice tool is included in Chrom{e,ium} under Tools → Developer
Tools, where - if you load an https-page, you get a little warning-sign
and a number in the bottom-right corner, which, when clicked, pops up a
list showing exactly what Chrome{e,ium} fetched that was insecure.

Yes, this will work:

$c-stash-{rs} =
$c-model('Foo')-search({%params});
# in page()
$c-stash-{paged_rs} =
$c-stash-{rs}-search({}, {page = $p, rows = $r});
...if that's what you're asking.
Other interesting things you can do:
sub add_item :Chained('list') PathPart('add') Args(0) {
my($self, $c) = @_;
$c-stash-{rs}-create({ %more_params })
}
sub related_items :Chained('list') PathPart('related') CaptureArgs(0) {
my($self, $c) = @_;
$c-stash-{rs} = $c-stash-{rs}-related_resultset('');
}
sub related_page :Chained('related_items') PathPart('page') Args(0) {
my($self, $c) = @_;
$c-forward('page');
}
sub related_csv :Chained('related_items') PathPart('csv') Args(0) {
my($self, $c) = @_;
$c-forward('csv');
}
Assuming %params in list() was a simple key/value map, add_items() is
going to use those, in addition to whatever's in %more_params, which is
cool because if you change the criteria in list(), it propagates
everywhere else as well. Plus, you reuse the page/csv implementation
easily. The combination of chained DBIC resultsets and catalyst chains
is very similar to curried functions (I believe that's what the initial
design goal was).
Excellent.* Catalyst chaining is awesome. Especially *related_items*, very
sweet.
The next question is, what's an elegant way to separate pager-params from
search-params? Page-params are always query_params, and search-params are
*usually* body_params ...but not always. What we're trying now is having
page-params be one letter: r=rows, p=page, o=order. A database field should
be far more descriptive than a single character, so that's our line in the
sand. Or should we just *$param = delete( $c-req-params-{$key} )* to
prevent double-handling?
Are there best-practices out there for this?
==
*...except our search-form is different from our entry-form. For example, we
let the user choose a range of dates which asks for two values (closed_begin
to closed_end) to search for a value in a single field (closed).

[Catalyst] Sanity Check -- requesting feedback on chaining approach
Catalystas -- this chaining stuff is wicked awesome. We've been following
the below paradigm for the most part, and now we want to expand a bit:
package MyApp::Controller::Xyzzy;
sub base : Chained PathPart('xyzzy') CaptureArgs(0) { }
sub list : Chained('base') PathPart('') Args(0) { }
sub item : Chained('base') PathPart('') CaptureArgs(1) { }
sub view : Chained('item') PathPart('') Args(0) { }
The two new nodes we want to insert are for csv-download (delivering all
records) and paging (delivering a subset). Here's what we're thinking:
package MyApp::Controller::Xyzzy;
sub base : Chained PathPart('xyzzy') CaptureArgs(0) { }
sub list : Chained('base') PathPart('') *Capture*Args(0) { }
*sub page : Chained('list') PathPart('') Args(0) { }
sub csv : Chained('list') PathPart('csv') Args(0) { }
* sub item : Chained('base') PathPart('') CaptureArgs(1) { }
sub view : Chained('item') PathPart('') Args(0) { }
Here the index view would come from *page*() instead of directly from *list*().
*csv*() would download resultset-search-({%params})-all whereas *page*()
would resultset-search({%params},{page=$p,rows=$r}).
So any search parameters would be handled inside list() and then paging
parameters would be handled separately inside page(). Right? Is there an
elegant way to separate the two sets of parameters?
Does this seem like a best practice? Comments welcome.

[Catalyst] Question about workflow to handle multiple 'submit' buttons on one form
Catalystry: We have a ticketing system where the managers can add new data and update the form. This uses a normal submit button. But now and then they want to close an incident, so we have a save-and-close submit button as well. One form, two ways to submit. So there's a second page where they fill out some finalization options (with the original data in hidden fields) and there they have a final submit button for the purpose. And they should be able to use their browser's back button to get back to the edit form. What's the elegant way to handle this in Catalyst? The problem we're wrestling with is that the edit action should have a URL distinct from the close action so that the user can hit the back button if need be. /item/# = view item /item/#/edit = edit form /item/#/close = confirm-close form We're using HTML::FormHandler and DBIC. And the solution shouldn't rely on javascript.

Nah. I wouldn't have two URLs. I'd have one URL, and determine whether
to save or save+close based on the value of the submit button.
Furthernore, after a successful submit (assuming http POST) I'd redirect
the user to a new display page via GET so that they can hit the refresh
button all the like without attempting to repost the submission.

The problem is that that flash entry is gone after the user submits the
login form. I logged out the redirect URL at the beginning of my login
routine and it comes through the first time, but even if I don't access it
via the log statement, that redirect_url key is not there in the flash when
the user submits the login form with their credentials.
I've tried resetting $c-flash-{redirect_url} in the login routine and
also tried $c-keep_flash( qw( redirect_url )) in the login routine, but no
go.
Any thoughts on what I might be doing wrong?

Re: [Catalyst] Saving redirect URL in flash not sticking through login process
I think stash is the ephemeral one-shot hashref, whereas flash is the
next-request's preloaded stash. That is, you can load up your flash with
whatever you need, and then do a full $c-res-redirect() somewhere -- which
fires off a browser redirect and a new request -- and your then-stash will
have all the goodies you plopped in there.
And, being the stash, it's all wiped out when the request is done. So a
follow-up request (or redirect) would either have an empty stash, or it'd
require the second request-handling routines to stuff things into flash
(again).
So it's not that flash is permanent, it's not. It's just a pre-load for
the next-request's short-lived stash.

Re: [Catalyst] Saving redirect URL in flash not sticking through login process
Altho the implications here
http://search.cpan.org/~bobtfish/Catalyst-Plugin-Session-0.31/lib/Catalyst/Plugin/Session.pm#METHODS
are that you can do multiple redirects with one $c-flash -- to wit:
The flash data will be cleaned up only on requests on which actually use
$c-flash (thus allowing multiple redirections), and the policy is to delete
all the keys which haven't changed since the flash data was loaded at the
end of every request.
We just treat it as a preloaded stash, and that seems to work fine for us.
If we want a more permanent chunk of data, we inject it into $c-session.

[Catalyst] In HTML::FormHandler search form (no DB schema) -- how to populate a SELECT field via DBIx::Class?
*Short version*: If you have a HTML::FormHandler search form without a
has_field '+item_class' (there's no data-base row corresponding to its
contents) how to you reach your DBIx::Class schemas to populate a drop-down
menu?
*Long version*: This is in the context of a Catalyst app -- however, I do
know this is either FormHandler question or a DBIC question, and not
intrinsically a Catalyst question, but... hoping the wise folks here can
nudge me in the right direction...
We have several DBIC resultsets including Incident and Country. The Incident
record has this relationship:
__PACKAGE__-belongs_to( 'country' =
'Incident::Schema::DB::Result::Country' );
(And the country schema has_many incidents, of course)
For the CRUD form related to the actual incident table, we have a matching
HTML::FormHandler package with its
has '+item_class'
as expected. This makes it easy to create a
sub options_country {
my $self = shift;
return unless $self-schema;
my $rs = $self-schema-resultset('Country');
#...
}
subroutine for the form, for populating a country drop-down menu in the
HTML.
But!
For the SEARCH form, we are not interested in CRUD, plus we have extra
fields (for example, we want the user to be able to bracket dates with a
start-field and an end-field) so there's no one-to-one correlation with the
database table -- meaning there's no item_class for the search form. And
hence no schema to rely on.
What we're looking for now -- unless there's a better more obvious paradigm
-- is a way to get from an instance of the schema-object, back to the
resultset, for searching.
sub options_country {
my $self = shift; # note $c is not available here :(
# $self-schema will be UNDEF here
my $obj = Spill::Schema::DB::Result::Country-new; # Hard-wired, yes, is
there a better way?
my $rs = $obj-???
# ?
}
I've looked at
- $obj-result_source (Can't call method resolve on an undefined valued in
DBIx/Class/Row)
- $obj-result_source_instance-resultset (Can't call method
default_resultset_attributes on an undef value in DBIx/Class/ResultSource)
- $obj-result_source_instance-resultset_class-search({},{}) (Can't use
string as a HASH ref in DBIx/Class/ResultSet)
and a couple other dead ends.
It's likely to be something obvious I've overlooked. :( Suggestions?

[Catalyst] Roles and Permissions -- Controller vs View
In our web app we have lots of features that are predicated upon the user's role. For example, a show link is available to everyone, but an edit link is only available to managers. Is there a best-practices approach for dealing with this? There are two places where user-role is significant -- controller and view. In the controller we use chaining to bounce a user out of an edit method if they don't have the right role. And in the view we use lots of [% IF c.user.is_mgr %] logic to determine whether or not to display the links. (Using user-friendly urls like /thingy/27/edit makes the URL easy to guess, so checking inside the controller is a good idea.) So right now we're checking for the same thing in the view that we're checking for in the controller. The more features that get added that require role-checking, the more hairy this gets. Is there a way to get all this rolled up into one place? Or at least make the view a bit more elegant? -- Failure is not important.

[Catalyst] receiving form-elements in sequence...?
Quick question: how do we determine the sequence of submitted form elements? Background: we've got several data-rows that we're going to let the user reorder via Javascript drag-and-drop. Looking in $c-req-params, being a hash, gives us all elements, but no clue as to which item is first, which is next, which is last. So in case the opening line above isn't quite the right question, how do we submit a new sequence of rows via $c-req? This is probably a simple one, but we haven't found the $c-req-[sequenced-form-items] method yet (gotta be available via Catalyst::Request, I hope). Pointers gladly welcomed.

#...
has_field 'agencies' = ( type = 'Multiple' );
has_field 'contractors' = ( type = 'Multiple' );
)
And then once we get the has straightened out, how do we use it?
%roles = $self-actor_role( @get_roles ); # ??
@success = $self-actor_role( %set_new_roles ); # ??

__PACKAGE__-has_many( map_incident_agency =
'Spill::Schema::DB::Result::IncidentAgency' = 'incident' );
__PACKAGE__-many_to_many( *agencies* = 'map_incident_agency',
'agency' );
__PACKAGE__-has_many( map_incident_contractor =
'Spill::Schema::DB::Result::IncidentContractor' = 'incident' );
__PACKAGE__-many_to_many( *contractors* = 'map_incident_contractor',
'contractor' );
meanwhile in the form...
package *Spill::Form::IncidentForm*;
use HTML::FormHandler::Moose;
extends 'HTML::FormHandler::Model::DBIC';
has '+item_class' = ( default = 'Incident' ); # ties it to DBIC
#...
has_field '*agencies*'= ( type = 'Multiple' );
has_field '*contractors*' = ( type = 'Multiple' );
then in the controller...
package Spill::Controller::Spill;
use Moose;
use namespace::autoclean;
BEGIN { extends 'Catalyst::Controller'; }
#...
has '*form*' = (
isa = 'Spill::Form::IncidentForm',
is = 'rw',
lazy= 1,
default = sub { Spill::Form::IncidentForm-new },
);
#...
sub my_action : Action {
#..
my $form = $c-*form*;
my $obj = $c-model('blah')-find_or_new({id=$id});
return unless process( # *MAGIC!*
item = $obj, # take this database object
params = $c-req-params, # and update it if everything validates
);
#..
}
With those definitions in place, your [% form.render %] (or [%
form.render_field('agencies') %] if you're hand-rolling your form) will do
the right thing, no problem!
If you need to filter the items that populate the multi-select list, no
problem. There's another link between incident and, this time, person --
only we want to limit the person-list to just those related to the org in
the incident itself:
# back in package *Spill::Form::IncidentForm*
sub options_persons {
my $self = shift;
return unless $self-schema;
my $persons = $self-schema-resultset('Person');
my $org = $self-field('org')-init_value;
$persons = $persons-search(
{ $org ? (org = $org) : () },
{order_by = ['lname','fname']},
);
my @persons;
while ( my $person = $persons-next ) {
push @persons, {
value = $person-id,
label = $person-name,
#active = $person-active,
};
}
return \...@persons;
}
The active label seems to be ignored when we do this, unfortunately. And
really we should pull org from $c-user instead of the form.
But whether you roll your own list or let FormHandler/DBIC pull them all --
in your browser you get a multi-select list of all the items in each
many-to-many relationship, and users can click to turn them on or off. Click
submit, and the linking-table gets updated accordingly. Very, very nice!
Catalyst, DBIx::Class, HTML::FormHandler, Moose -- woo hoo! Kudos, big fat
thumbs up!

[Catalyst] Catalyst and Moose with has many_to_many
Greetings Catalystery: Got a new question, trying to implement a
many_to_many
relationship via Moose... The DBIC portion of the puzzle is straightforward,
we've got
that working just fine.
Here's part I understand -- we have a controller that's referring to a form:
has 'form' = (
isa = 'MyApp::Controller::Incident::IncidentForm',
is = 'rw',
lazy= 1,
default = sub { MyApp::Controller::Incident::IncidentForm-new },
)
then
$c-stash-{form} = $self-form; # etc
Piece of cake!
But how would you represent and then refer to a *many_to_many* relationship
such as
has 'actor_role' = (
isa = 'MyApp::Controller::DB::Result::ActorRole',
is = 'rw',
lazy= 1,
# default = sub { MyApp::Controller::DB::Result::ActorRole-new }, # not!
# default = sub { ...-add_to_roles(??) }
)
And then once we get the has straightened out, how do we use it?
%roles = $self-actor_role( @get_roles ); # ??
@success = $self-actor_role( %set_new_roles ); # ??
I've looked through
http://search.cpan.org/~frew/DBIx-Class-0.08124/lib/DBIx/Class/Relationship.pm#many_to_many
until my eyes cross on their own :(
Or am I barking up the wrong tree?

Re: [Catalyst] Re: Trying out FormHandler, running into maketext error
Not sure what your case sensitive remark refers to -- and if it's looking
for something to be defined XXX that's defined xxx instead, that particular
error message is really out of left field.
Do you mean something like
has_field 'submit' = ( widget = 'submit' )
should instead be
has_field 'submit' = ( widget = 'Submit' )
with a capital S?
The following is definitely working for us now:
has_field 'submit' = (type = 'Submit', label = 'Submit', value='Submit',
required = 0, )

Also you should not have any non Catalyst::Controller subclasses in the

Move you forms to My::App::Form for example.

Yes indeed, the undef error - Unable to do maketext on:

error has gone away thanks to tweaks to the SUBMIT button on the

Re: [Catalyst] Re: Trying out FormHandler, running into maketext error
From %ENV there are only two LANG* keys:
'LANG' = 'en_US'
'LANGUAGE' = 'en_US:en_GB:en'
Looking at the docs for HTML::FormHandler::TraitFor::I18N it sure looks
flexible for moving toward a multi-language webapp, but when we just want a
quick proof-of-concept, we'd hope that there are some nice convenient
defaults that just work. :(
Do we have to spend hours reading a whole set of manpages on
internationalization just to get our first elemental form to render? Surely
there's an elegant get-off-the-ground approach... This seems like a huge
detour that won't be productive, except for getting past this speed bump.
It's not that we're avoiding work, we're avoiding time-sinks, and this looks
like a time-sink.
E.g. we don't have a module MyApp::I18N with a new() method and hope to not
need to learn how to build one...
It'd be great (not to mention necessary/useful) if we were looking to
internationalize our app, but we're not.
So, is a study of I18N the One True Path to getting a form to render? Or is
there something simple we missed?

[Catalyst] Re: Trying out FormHandler, running into maketext error
Pooh. Still no luck. When we try a more more Moose-y approach, we do get
updated database records (stuffing the URL with arguments to affect a

undef error - Unable to do maketext on: at

That is, we're using this approach, and still having trouble with [%
form.render %]:
package MyApp::Controller::Admin;
use Moose;
use namespace::autoclean;
BEGIN {extends 'Catalyst::Controller'; }
{
package MyApp::Controller::Org::OrgForm;
use HTML::FormHandler::Moose;
extends 'HTML::FormHandler::Model::DBIC';
with 'HTML::FormHandler::Render::Simple';
has '+item_class' = ( default = 'Org' );
#...fields here
}
has 'form' = (
isa = 'MyApp::Controller::Org::OrgForm',
is = 'rw',
lazy= 1,
default = sub { MyApp::Controller::Org::OrgForm-new },
);
sub org :Local :Args(0) {
my ( $self, $c ) = @_;
my %params = %{ $c-req-params };
my $org = $c-model('MyApp::Org')-find_or_new( {id = $params{id} || 1}
);
my $form = $self-form; # takes quite a while to initialize this
$c-stash-{form} = $form;
return unless $form-process(
item = $org,
params = \%params,

$c-stash-{message} = Org record . ( $params{id} ? updated :

}
Any suggestions or clue-sticks welcome. Thanks!

Re: [Catalyst] Catalyst and FormBuilder vs. IExplorer 8
Well this is just odd.
When Firefox, Chrome and IE6 submit files-to-upload, the structure returned
by $c-req-uploads is DIFFERENT for explorer -- it's an ARRAYREF instead of
a HASHREF:
DB2 x $c-req-uploads
*0 HASH(0x9d04d20)*
'*newatt[1]*' = Catalyst::Request::Upload=HASH(0xb81a098)
'filename' = 'japh.pl'
'headers' = HTTP::Headers=HASH(0xb448c28)
'content-disposition' = 'form-data; name=newatt[1]; filename=
japh.pl'
'content-type' = 'text/x-perl-script'
'size' = 104
'tempname' = '/tmp/6V0Vlas5td'
'type' = 'text/x-perl-script'
'*newatt[2]*' = Catalyst::Request::Upload=HASH(0xb448c88)
'filename' = 'TODO'
'headers' = HTTP::Headers=HASH(0xb650140)
'content-disposition' = 'form-data; name=newatt[3];
filename=TODO'
'content-type' = 'application/octet-stream'
'size' = 29
'tempname' = '/tmp/2RTgotIgut'
'type' = 'application/octet-stream'
The same attempted upload for Explorer 8 looks like this instead:
*0 ARRAY(0xab06360)*
* 0* Catalyst::Request::Upload=HASH(0xb448c88)
'filename' = 'japh.pl'
'headers' = HTTP::Headers=HASH(0xb81a098)
'content-disposition' = 'form-data; name=newatt[1]; filename=
japh.pl'
'content-type' = 'text/x-perl-script'
'size' = 104
'tempname' = '/tmp/3Tg94Iq85j'
'type' = 'text/x-perl-script'
*1* Catalyst::Request::Upload=HASH(0xb448c28)
'filename' = 'TODO'
'headers' = HTTP::Headers=HASH(0xb448c88)
'content-disposition' = 'form-data; name=newatt[3];
filename=TODO'
'content-type' = 'application/octet-stream'
'size' = 29
'tempname' = '/tmp/T2r9F7Ex11'
'type' = 'application/octet-stream'
The structure of each node is the same, but as a whole the upload-list
switches internally from a HASHREF to an ARRAYREF. IE6, FireFox, Chrome all
bring in the Hashref, but IE8 brings in an Arrayref.
On top of that, if there's just one upload, it's not even an array, it's
just the node itself.
What the heck? Sure seems odd to offer a different storage structure based
on browser-platform...

Ugh, I hit this a little while ago, but have forgotten the details
already.
I think you are looking in the right direction with the this though; try
validating it in your function to ensure it contains what you're expecting
perhaps?
Also, can you verify that jquery is actually getting loaded OK?
ie. In your document, put something like:
$(function() { alert(jquery has loaded!); });
and check to see that you get an alert box when you load the page. If not,
fire up Chrome's developer tools, or Firefox's Firebug, and see they mention
any warnings or errors.

[Catalyst] Catalyst and FormBuilder vs. IExplorer 8
Short version: Catalyst/Formbuilder uploads work fine in firefox and chrome, works fine in IE 6... but not IE 8, where it throws an object expected error. Long version: We've got a weird situation -- Catalyst and FormBuilder work together to generate HTML for a form including file uploads -- which work fine for older Internet Explorers, but when attempting the POST using Explorer 8, instead of an upload we get the error Object Expected line 215 char 1. If we opt not to upload anything, the rest of the fields in the form get posted just fine. Line 215 is: form action=/incident/2129 enctype=multipart/form-data id=incident method=post name=incident onsubmit=return validate_incident(this); input id=_submitted_incident name=_submitted_incident type=hidden value=1 / The only thing there that looks like a suspect would be onsubmit=return validate_incident(this), right? If you've run across this and know how to straighten it out, that information would be very much appreciated. In particular... Is there a way to fix this with a configuration arg to Catalyst (v5.80027) or to FormBuilder (v3.0501)? ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/
[Catalyst] Design/architecture question -- search-results with a modify-search-field
Here's a high-level situation we're wrestling with: /item/list = show all, with paging /item/search = display search form, or use list.tt2 template for result display, with paging Of course, that approach right there may be causing some of our headache... :) But that part is all working fine and dandy. The question is, what's an elegant way to put one quick search field on the list.tt2 template to tweak the cached/existing search (or to tweak the list-all)? In this case it's a category of /item, and that category field is also on the dozen-field form as well. Kind of like when doing a google search and switching between images and news and videos and maps. What's best? Have the list.tt2 category-form action point to an /item/category method and then forward to /list? Have the list.tt2 category-form action point to /item/search and fill out a subset of parameters? Nothing we've tried feels clean, certainly not DRY. Suggestions welcome.

[Catalyst] How to get from
Short version: we're wondering how a method from inside the SCHEMA can
return other
objects besides the one that got passed in. That is, we have $obj
(with its own ID
number) but we want to FIND a different object -- same type, but with
a different
ID number. What's the mechanism for that, inside the schema package?
Long version:
We've got a schema defined for hierarchical groups:
MyApp::Schema::DB::Result::Group
__PACKAGE__-add_columns(
id,
{ data_type = INT, default_value = undef, is_nullable = 0, size = 11 },
name,
{
data_type = VARCHAR,
default_value = undef,
is_nullable = 0,
size = 90,
},
parent,
{ data_type = INT, default_value = undef, is_nullable = 1, size = 11 },
);
__PACKAGE__-set_primary_key(id);
__PACKAGE__-belongs_to( parent = 'MyApp::Schema::DB::Result::Group'
= 'parent' );
__PACKAGE__-has_many( subgroups = 'MyApp::Schema::DB::Result::Group',
{ 'foreign.parent' = 'self.id' },
{ order_by = 'name' },
);
So when there's an ID number in parent the current group object has
a parent group
object. When there's no ID (or it's zero) then that's the top-level group in its
hierarchy.
Creating a method for the top-level group is simple:
sub top {
my $self = shift;
my $top = $self;
while ( $self = $self-parent ) {
$top = $self;
}
return $top;
}
If we're looking for a certain PARENT with a given ID, that's simple too:
sub specific_parent {
my $self = shift;
my $id = shift;
while( $self-id != $id ) {
return unless $self = $self-parent;
}
return $self;
}
But how do we go about creating a method to look for a specific group by ID
that may not be in the parent-chain?
sub specific_group {
my $self = shift;
my $id = shift;
return unless $self-some_manner_of_valid_id_check( $id );
return $self-BLACK_MAGIC_HERE-find( {id=$id} );
}
So the real question is, how do we get from $self to -find() ?

Re: [Catalyst] How to get from
Thanks, Tom -- But this apparently isn't a result-class, or I'm just missing something obvious: DB5 p __PACKAGE__ MyApp::Schema::DB::Result::Group DB7 p $self MyApp::Model::MyApp::Group DB8 p $self-resultset Can't locate object method resultset via package MyApp::Model::MyApp::Group === Working from the context of a Catalyst app, I'm not sure I'd be able to properly abstract the right question for the DBIC list (or be able to apply the answer back to my concrete catalyst app). :) Folks on this list have been delightfully helpful despite us newbie-questions, especially you... Plus, being rather new to Catalyst, it's difficult to see where the edges are between Catalyst, DBIC and Moose.

Ah -- yes indeed, that did the trick. That chain was a bit longer than
I could put together on my own.
Thanks!
