The real question is whether your ORM should be directly in the model or
not, but that's a whole different thread.
Based on this I have the following simple code.
package MyApp::Model::DBIC;
use strict;
use base qw(Catalyst::Model::DBIC::Schema);
package MyApp::Schema::Demo;
use base qw(DBIx::Class);
__PACKAGE__-load_components(qw(PK::Auto Core));
__PACKAGE__-table('demo');
__PACKAGE__-add_columns(qw(id name state));
__PACKAGE__-set_primary_key('id');
package MyApp::Model::DBIC::Demo;
Put this code in MyApp::Schema::Demo.
I often call it e.g. MyApp::DataStore or MyApp::Domain to remind me that
it's the business layer and the DBIC-ness is merely incidental.
sub do_some_business_logic_stuff {
my ($self) = @_;
if (some complicated business logic) {
$self-state('pending');
$self-update;
}
}
somewhere in my application
$demo = $c-model('DBIC::Demo')-find($index);
$demo-do_some_business_logic_stuff;
-
Is this a standard/typical/best-practice way to do this sort of thing?
It seems to me that if I want to use the business logic in an external
application (cronjob) then I am having to use the MyApp::Model::DBIC::Demo
namespace as decreed by Catalyst (not that this is a big issue).
Having moved the logic out of MyApp::Model:: this ceases to be an issue.
Don't confuse class -names- with the nature of classes. MyApp::Model:: is
*adapters* that make a model available to MyApp, not where your domain model
logic itself should live.
I usually these days have MyApp::Web for the catalyst app instead of MyApp so
I can deploy things like MyApp::DataStore from a separate dir tree.

Have you looked at the way the Handel storage stuff works? That already
supports both DBIC and RDBO so might be an interesting start.
I have looked through it (I had to figure out that Handel-Storage-RDBO is
packaged separately...) and it looks like the base Storage API is much more
complex and full-featured than what I am suggesting. But all the methods I
mention are there in one or another. I'll probably dig in to the DBIC
implementation when/if I need help with that part of CXCM (/me hoping not
write
that all by myself...).
Yeah, don't blame you :)
Do you have any thoughts on how to paper over DBIC's ability to chain
searches
vs. the lack of that feature in RDBO? I know most RDBO users don't feel
they're deprived not having it but DBIC users are generally fairly addicted
:)
I've read about that feature difference in the mail archives, but since I
haven't used DBIC myself, other than to just play for about an hour, I'm not
sure what the equivalent RDBO code would look like. I do all kinds of multiple
relationships in my RDBO code, where I chain together method calls to get at
related data. Is the difference that RDBO might be making multiple db calls,
whereas DBIC doesn't?
For example, in your reply to Perrin you used this example:
This sort of thing in DBIC just becomes
$posts_rs = $users_rs-search_related('posts');
In RDBO, if I wanted all the posts for a given user, I might just say:
$posts = $user-posts;
So how is that different? Because $users_rs might represent multiple users? If
so, yes RDBO would require something a little longer, like:
map { push @posts, $_-posts } @$users;
Which, depending on if I pre-fetched the posts when creating $users, might end
up being lots more trips to the db. And it doesn't give me $posts_iterator,
which might be preferable to @posts.
The main diff here is the DBIC users_rs could represent many users without
ever actually fetching them.
Looking at your example though, I think I'm worrying too much.
But I think for the purposes of this CatalystX::CRUD proposal, the harder
issues are going to be abstracting the conversion of $c-params() to what gets
passed to search(), iterator(), count(), etc. Right now that is all very
RDBO-specific in CCR::Search.
Couldn't the whole DBIC search_related issue just be resolved by pushing the
issue out into the controller and/or view space? In your CCR::Search subclass:
my $results = $c-model('My::CatX::CRUD::Model::DBIC')
-search(@params)-search_related('foo');
I think we'd just end up providing traverse_related methods that did stuff.
The RDBO implementation might be a little less efficient than the DBIC one
but for the sort of workload we're looking at here it's probably -fairly-
academic performance-wise.
And if it's not, you can go bug siracusa until that changes :)

As you indicate below, you don't use any of the C::C::Rose code, design or philosophy, so sharing the namespace seems misleading at the very least.

Perhaps something like CatalystX::RHTMLOManager or similar. Well... I don't mind to call it something else, so now I'm just (once again) looking for a good name. CatalystX::Something, ok. CatalystX::RHTMLOManager, NOK because it also deals optionally with RDBO and I would like to mention this fact, and I think the best way is to use the Rose name. I think you should just rewrite the damn thing to use Controller::Rose. That seems like a much better idea to me since Peter Karman's code is already pretty stable and provides most of the things you need. Just provide a different interface on top.

Isn't it primarily a way to build up your search criteria with
multiple small method calls instead of one big one? It doesn't seem
very relevant to a CRUD app where all the criteria come in at once
from a web form.
You've never implemented a saved search function that allows you to
'search within' a saved search?
You've never done a view all posts owned by the selected set of users link?
This sort of thing in DBIC just becomes
$posts_rs = $users_rs-search_related('posts');
whereas (so far as I'm aware, please do correct me if I'm wrong) it's a bit
more work in RDBO.

I'm not an expert on RDBO, but I believe you would need to call a
different class (the posts class, not the users) and adjust the
criteria you pass, e.g. change last_name = 'Smith' to
user.last_name = 'Smith'.
Any set of ORM tools is going to have different unique features, and a
full abstraction would mean giving up all of the unique features.
However, it looked like Peter was trying to do something at a pretty
high level where hopefully the differences don't come into play much.
So the answer is no, I don't have any ideas about this. Sure, fair enough.
You could have said that in one line though, I was only wondering.
I'll wait and see whether Peter does.

In other words, ::BigThing could be renamed to MyThing, the chained uri follow suit from /bigthing/ to /smallthing/ and everyone is happy. The minute you add a child class into the mix (SmallThing), you have to hardcode Chained in SmallThing with the name/private/path pointing to BigThing.

Therefore the error string I get is something like command ignored until end of transaction block. Something's numifying the $rs thus causing -count to be called. Thanks for the tip. I suspect is't something out of my control, otherwise the problem would show up also when I'm not using the -d flag, right ? I'd like to track this problem down, but I think I'll have to dive into the internals of cat and/or dbic... which I'm not familiar with. Do you have any other suggestion for where to start looking for differences in behaviour between -d and normal run ? Thank you again. It may be when the debugger displays the rs.

I think that one is a pipe dream so I'll happily use my solution above for now. Couple of notes: (1) it's DBIx::Class, DBIx:: is the namespace for -all- DBI extensions (2) it has its own mailing list As for automatically detecting the constraint, if you use $schema-deploy to let DBIC generate your CREATE TABLE statements for you it puts in the constraint cascades automatically so you'll never see a problem. We intentionally don't override cascade/fk settings on your database to avoid buggy code causing mass dataloss (I've seen this many times before now with ORMs that try to be helpful the way you're requesting) - DBIC -will- try the delete -after- deleting the main record for DBs like SQLite without FKs, but in the case where your database has constraints DBIx::Class prefers to respect them. Either do the cascade clearly in your own code or make sure your DB schema's correct - at least that way when a cascade wipes out a load of data it's easy for the maintenance programmer to see why and how it's happened :) -- Matt S Trout Need help with your Catalyst or DBIx::Class project?

Hi all -
Quick introduction: I'm new to Catalys, but I've been reading the
mailing list online for some time. I finally have a suitable project
and have just started working on it. The documentation on list so far
have been a great help.
My question: I'd like to unbuffer output a la $|++. I thought one
approach might be to have a series of templates per page, rendering
each sequentially, delivering each to the client in turn.
So far I've come across two possible solutions: 1. SubRequest and 2.
View::TT-render.
But it seems that trapping the output of either and writing to STDOUT
closes the request, such that only the first template is rendered and
sent to the browser.
$c-finalize_headers;
foreach my $argset (@argsets) {
$c-write($c-view($view_name)-render($template, $argset));
}
or code to that effect.

I'm not looking to build Drupal or a blog platform but I have nothing against them per se. I was thinking more of a tool to reduce the amount of Catalyst code I type by identifying patterns. For example: - A multiuser pattern in which a site is separated into public, admin and registered user portals (of which the latter two need to edit lots of pesky data like their profiles, their virtual holdings like coupons/listings/catalogs/resumes/banners//video clips, etc.). Currently I would do this with a formbuilder form, view and save subs, and TT template for each page. Reaction's action reflector plus the ActionForm viewport - Another pattern might be to get one or a list of objects a user owns, make a list of them and create an interface allowing them to edit and save the data. We all keep reinventing the wheel with this. Reaction's action reflector plus the ListView, ActionForm and CRUDController classes. Currently I would look at similar subs I'd made and well reinvent the wheel... I have 3 ideas at the moment. 1a. A standard object editor with rich editor and maybe some widgets. It would render a complex form as necessary, given the object to be edited. I once wrote something like this that would just let you edit object data fields with text input boxes, it's not rocket science. Done. 1b. Online asset manager to CRUD them, with a file upload widget might also be nice. Mostly done. 2a. Reduce the set of all information assets a user owns into a single tree that may span many tables, allowing each asset (object, data field, etc.) to be called from templates by name (could use namespaces and dot notation maybe). This is probably most useful in the context of having a tree of all text snippets, etc. used in display of the public site. Doable using metaprotocol introspection. Right now you need to feed Moose the info by hand but in DBIC 09 it'll be baked in. 2b. This reduces templates to a list of assets (snippets) called by name interspersed with HTML tags and TT directives. Text snippets would reside in a database and could be edited in a CMS, at least like the utility of 1a/b above. Image pathnames or a single DIV's HTML could also all be stored in the db. The template would just pull the snippets out with a simple $c method like loc in the above I18N modules. A standard facility for editing these things (a module and TT templates) would also be useful. I'm mostly just using the i18n plugin plus a tree of files under svn for this but our designer learned svk shortly after wiping windows in favour of ubuntu in a fit of anger with it during LugRadio Live. 3. Beyond this, I see an awful lot of programming and design going into solving similar basic interface problems over and over. It would be useful to provide some basic TT layouts and scripted user interactions (I don't mean write perl script, I mean just write the basic plot, preferably as an interpreted string of text but even yaml could be used). Agreed. The new reaction widget model works towards the latout part, I was planning to hook Class::Workflow to handle the scripty bit. Currently we sometimes reuse templates (for example I have a general modal dialog), but we don't really have smart systems that DWIM the user interaction for basic data editing. For one thing, we all look at each other's public sites but not the admin or user portal pages which could require more programming work. Contributing to solving repeated patterns once well will make Catalyst even more powerful I think. A repository of such interface snippets (combination of TT code, perl code, etc.) could be run on the dev site maybe. At the risk of sounding like I'm all talk I'm willing to provide my current admin and customer portals to the project, possibly the TT templates would be useful. Anyway they do look a little like the Catalyst startup page. :) I'd love to see the code publically, even if it isn't re-used it's instructive to see how other people do it. In the same spirit: http://trout.me.uk/scsite.tgz is the Shadowcat website code base running on svn reaction from http://code2.0beta.co.uk/reaction/svn and I intend to artistic license the site codebase (not sure what we'll do about the content and layout yet, but I don't imagine our website copy is of great re-use value to anybody else anyway :) -- Matt S Trout Need help with your Catalyst or DBIx::Class project?

Is my mistake in misunderstanding how $c-log-debug() is supposed to work? Yes. That logs a message of level 'debug'.

From Joe Landman (Sun, 22 Jul 2007)
Hi folks:
Using XMLRPC for some service method calls to make life
easier/cleaner for some of our code. I am doing something wrong, as
I get errors (at the end).
I set up a simple application using the usual methods
catalyst.pl RDB
cd RDB
script/rdb_create.pl controller Job
I then set about to use portions of the examples in the
Catalyst::Plugin::Server::XMLRPC . Specifically I created a ping and
echo method, to test. I placed these in the Job.pm (rather than
Root.pm ... is this an issue?). This is what they look like.
sub echo : XMLRPC { # available as: job.echo
my ( $self, $c, @args ) = @_;
$c-stash-{xmlrpc} = join ', ', @args;
$c-log-debug($args[0]);
}
sub ping : XMLRPCPath('/job/ping') {# available as: ping
my ( $self, $c ) = @_;
$c-stash-{xmlrpc} = 'Pong';
}
Ok. Light up the server, comes up fine:

Now try the echo call:

I get this on the client side:

$VAR1 = {

};
And I get this on the server side:

Basically it is telling me that it doesn't have a view to forward to.
Is this needed in Server::XMLRPC ? I thought it did html encapsulated

Any thoughts/clues? Thanks.

Hello,
when playing with Catalyst::Plugin::Server::XMLRPC following the
documentation, I get the same behaviour as Joe.
I have search the archive and found thie mail from Joe Landman , and he
has the same problem, but unfortunately, nobody answer him.
I have copy/paste his email because his setup and mine are the same, and
I don't have my script available right now.
To get my app running, at the end of my RPC function, I must put an
$c-output(' ').
I would like to know if it is the correct thing to do, or I'm doing
something wrong.
I'd do -
sub end :Private {
my ($self, $c) = @_;
$c-forward('render') unless $c-req-xmlrpc-is_xmlrpc_request;
}
sub render :ActionClass('RenderView') { }
Seems a bit cleaner than your approach.

Re: [Catalyst] RFC: Multiple :Chained and/or :PathPart attributes?
that could do this, but this is my first trip into the innards of the dispatcher, and it looks like it's going to take a while to wrap my brain around it, so if anyone has suggestions on how to implement this (or reasons that it's a very bad idea) I'd love to hear them... I don't have any thoughts on this particular idea, but I solved a similar solution by creating a common action class to handle the action stuff that was similar across a few of my controllers. Well, I'd make all but 'revision' 302 redirects since you should only have one canonical URI per resource. More importantly, I'd use a controller base class to provide the view action, then I'd just need one handler action method to load the target per controller and all the duplication would be removed. Trying to handle multiple :Chained attrs on a single action would get messy fast - I'd love to see it available but I don't see an elegant way to do it and still leave uri_for_action working correctly, and the controller base class approach seems to work fine for eliminating duplication. -- Matt S Trout Need help with your Catalyst or DBIx::Class project?

The main reason for this is that when I do

in the 't' directory.
That's the default behaviour. To add subdirs, put
tests('t/*.t t/*/*.t');

Good afternoon - I am working on a Catalyst application that serves

content (images, css, rss) and I am trying to serve that static

documentation on how to serve all static content from a single
directory, but not much on a servername-dependent directory. For
example:
Request: http://www.timjohnson.com/css/global.css
Should be served with: /var/www/html/sites/timjohnson.com/css/
global.css
I came close to making this happen just using the Alias directive
in httpd.conf, but I couldn't get that to accept a variable, %
{SERVER_NAME}, in it. If someone has a solution from the Apache
side, that's fine but I suspect that it might be easier to do this
with Catalyst::Plugin::Static::Simple, though I again have not
figured out how to tell it to use a variable name when it creates
the path the request is supposed to be mapped to. I am sending
this to the Catalyst list because I suspect it might be something
other people have faced before using Catalyst.
My setup is a recent version of Catalyst running on Apache 2.2 with
mod_perl. Any suggestions would be quite welcome - thank you very
much.
As has already been said, you should use Apache for this. But if you
*really* want to use Static::Simple, take a look at the docs for the
Including additional directories, and in particular the
incpath_generator sample code. You can write a bit of code that
returns one or more directories from which to serve static content.
Did we make _serve_static_file public yet? Having a way to do something
like that dynamically is the one thing I still -really- miss from the old
Static plugin.
... alternatively, we could always have Controller::Static blah blah plugins
evil blah yadda no really this time a plugin's fine :)

Redefine is the term in perl-lingua.
Not really, it's just subclassing.
Catalyst plugins (like DBIC components) just end up as extra superclasses
In MyApp.pm:
{
no warnings 'redefine';
# this line is completely pointless.
sub merge_session_to_user {
# your new sub
# ...
# To call the previous implementation if you should want it:
# $self-NEXT::merge_session_to_user(@args);
}
}
The key thing to remember here is that all Cat plugins 'pollute' the $c
namespace, which isa Myapp.
They end up on your @ISA, this polluting the namespace of potential method
names, but they don't pollute the MyApp package directly - that level of
stupidity I haven't seen since Class::DBI::Plugin::*

I have implemented a Plugin. How can I call a plugin method from controller

You shouldn't.
If you need to do that, the method shouldn't be in a plugin.
Don't hack up your Catalyst app, fix your design :)
suppose i have a Plugin named Catalyst::Plugin::MyPlugin contains a method
called sub myFunc {}
That should be my_func, not myFunc. This is perl, not java. Please stick to
the correct naming conventions for things.

I particularly use jQuery, the way that i pass the data from the

my $obj = [ map { { id = $_-id, name = $_-name} }

Always, -always- use View::JSON rather than doing the serialisation direct.
Otherwise you're writing an 'MC' system not 'MVC' and claco'll start making

Re: [Catalyst] Using Workflow with Catalyst (was Making Controllers thin and Models thick)

Hello,
I am the current maintainer of the Workflow module on CPAN and I just
want to add my 2 cents here, since Matts' comments on Workflow is in
my opinion are both unfair and inapproriate and not particularly
constructive. I am sure he has more constructive criticism and I
would like to discuss this with him the next time we meet, since Matt
seems like a sensible guy.
When I wrote Workflow off there hadn't been a release in some time and the
author was available but disinterested so an active maintainer seemed unlikely
to happen and we'd tried and failed to get patches merged.
I'm glad to see that's no longer the case, but it still strikes me as
massively heavy and clumsy for the job it does - anything where the synopsis
has *four* XML files before it even gets to any code screams overengineering
at me.
And of course, Workflow::Factory is a magic global (this week under the guise
of singleton, but it's still a magic global) so I can't rely on its
behaviour in any situation where I'm going to be running more than one app in
the same interpreter.
If I wanted to deal with overengineering -and- magic globals at the same time,
I could learn J2EE. As it is,
FACTORY-add_config_from_file(
workflow = 'workflow.xml',
action= [ 'myactions.xml', 'otheractions.xml' ],
validator = [ 'validator.xml', 'myvalidators.xml' ],
condition = 'condition.xml',
persister = 'persister.xml'
);
does not compare well to
my $wf = Class::Workflow-new;
$wf-state(
name = new,
transitions = [qw/accept reject/],
);
$wf-transition(
name = accept,
to_state = opened,
body = sub {
my ( $transition, $instance, $context ) = @_;
return (
owner = $context-user, # assign to the use who accepted it
);
},
);
to my mind. Perhaps it would be worth adding a way of setting up a workflow
in code and documenting that first rather than the XML format? (no, being
able to use four perl-syntax files instead of four XML files does -not-
count from my POV :)

I'm wondering about the implementation. I read that too. Interesting, but from what I see undo is not so easy to implement. One option is to create actions for every possible undo operation. That would mean that each undo operation would generate a specific link, including request parameters to identify the item that needed to be, well, undone. Another possibility would be to generate the code for the undo action and place it in the session so that there's just an /undo link. /undo fetches the code and evals/executes it. The /undo link would only be available for a single request after displaying the undo link. I like more the idea of a generic undo request. This could be part of a plugin providing this action and the necessary infrastructure to implement the un-doing of the action. I fail entirely to see why this should be a plugin rather than part of the model you're intending to make mutations upon undoable. This plugin could implement a simple version of the classic Memento pattern (http://en.wikipedia.org/wiki/Memento_pattern) I'd say DBIx-Class-Audit (currently in bast trunk pending more testing) already implements this pretty well for DBIC models - except it always saves the appropriate information, saving you needing to call anything at all to make the undo happen. -- Matt S Trout Need help with your Catalyst or DBIx::Class project?

I looked at two different approaches today that involved sending a SIGHUP signal instead, and I couldn't get either to work.

I suspect SIGUSR1 would work just fine; the 'authors' (mostly Sebastian) don't actually understand signal handling, I had to do quite a lot of cleanup work to make the child-related stuff sane. So, I think HTTP::Server::Restarter is good that part. The second module, Watcher.pm is not HTTP-specific, it just monitors a directory for changes, based some options. It is similar to: File::Monitor. http://search.cpan.org/~andya/File-Monitor-v0.0.5/ I suggest it be named File::Monitor::Simple Is there any reason not to switch to File::Monitor while we're here?

Odd, it doesn't cause any AS perl I've seen do that.
The perldoc for POSIX states in the strftime notes:
If you want your code to be portable, your format (fmt ) argument should
use only the conversion specifiers defined by the ANSI C standard (C89, to
play safe). These are aAbBcdHIjmMpSUwWxXyYZ% .
%T is not in the list. On all the systems I have at my disposal, %H:%M:%S
produces equivalent output and uses only the conversion specifiers they
recommend.
For the sake of saving the next soul who wants to use Catalyst under Win32,
which apparently doesn't like %T, suggest changing to:
my $time = strftime('%Y-%m-%d %H:%M:%S', localtime time);
While I see no reason at all not to make this change, could you elaborate
on your environment a bit?
This can't be all win32 since I know we've got happy users on win32 and
various perls (although VanillaPerl is getting more and more popular due to
various bits of ActiveState brain damage), so I'm curious now :)

What's wrong with that? I find it a lot more readable than

It doesn't work this way, but suppose you wrote this:
if ($bar) {
my $vote = $foo
}
Now see why it's wrong? The way you wrote it is kind of ambiguous for
the way we think of postfix operators. If you want something one line,
how about this:
my $vote = $foo ? $bar : undef;
I can't replicate this behaviour. As far as I can tell, the postfix if
is identical to the block if I wrote above.
perl -Mstrict -wle 'my $foo = 1 if 0; print defined $foo ? $foo : undef'
undef
Has the bug been fixed?
No, because people use the if 0 construct as a way to create a static.
cain$ re.pl
$ sub foo { my $foo if 0; $foo++; }
$ foo();
0
$ foo();
1
$ foo();
2
$
However in 5.10 you -will- get a warning using this construct since it almost
always indicates buggy code; the number of people who actually -need- a
static rather than just a lexically closed-over var is vanishingly small and
they can explicitly turn off the behaviour themselves.

if you're storing a 'user' object in the session, something like

Re: [Catalyst] Ask Catalyst: What are your prefered DB and HTML abstraction layers ?
On Thu, Jul 05, 2007 at 09:58:29AM +0200, Alexandre Jousset wrote: Hello list, I started a project using Catalyst with DBIx::Class and FormBuilder. This is far from a CRUD application. In fact it is a Slashdot-like application. I've heard about Rose and I'm planning to move from FormBuilder to Rose::HTML::Object that seems better designed. My real question is: should I also change the DB abstraction layer from DBIx::Class to RDBO ? Would this be more consistent? Does it worth it? Or can I live without it? I'm thinking in the long term. Since nobody else seems to have replied, I'll take a stab. I know quite a few people who've used RHTMLO with DBIC to great success, so a switch to RDBO definitely isn't -necessary-. On the other hand, I think the Catalyst::Controller::Rose stuff gives you out of the box integration so your question really is twofold - (1) Will it be more work to get your RHTMLO-DBIC integration going than it would be to port to RDBO and get RHTMLO-RDBO integration going? (2) Do you need any of the features DBIC provides that RDBO doesn't? (resultset chaining and support for GROUP BY/HAVING being the obvious candidates) Equally, (2) can be flipped, asking whether the features RDBO provides that DBIC doesn't (which I'm obviously not as clear on the list of :) are worth the effort of porting. In the long term I personally don't see RHTMLO remaining the state of the art in terms of form generation, but equally I do see it being the closest to good enough of the currently available options so perhaps you won't need to switch even when a better solution becomes available. RDBO is a very well-engineered project, and while it has a more measured development pace than DBIx::Class that does result in it being a bit more polished in places and the documentation is excellent. So ... I don't really have a straight answer for you. I know of quite a few devs who've gone both routes and been happy with it, and I can't really say whether one route is better or not - I think what I'd do is create a quick one-table test app using Catalyst::Controller::Rose, and port one of your current DBIC+FB controllers to DBIC+RHTMLO, and then decide at that point which approach you like better. -- Matt S Trout Need help with your Catalyst or DBIx::Class project?

Re: [Catalyst] Proper way to perform cleanups on server shutdown?

Hi,
I'm finding that the way I usually catch shutdown
signals to perform cleanup is not working. Setting
%SIG handlers doesn't seem to do it and I'm not
finding that DESTROY methods are getting fired off in
the expected way.
For example if I set a $SIG{INT} handler in the
application class (MyApp.pm) that get's called if I am
running the development server foregrounded and the
interrupt it with a 'ctrl-c', but it doesn't get
called if the development server is deamonized and I
kill the process. $SIG{QUIT} doesn't seem to do it.
DESTROY doesn't seem to every get called.
Add some better traces - I suspect this is either (a) a DBIC problem fixed
in 0.08 or (b) a problem that isn't that you didn't give us a test case for
yet :)

Re: [Catalyst] instantiating persistent DBHs: MyApp.pm? Model?

I'm looking to interface more directly with DBIC if possible in the future, but for now, things are working as expected. Bear in mind you can (a) get the $dbh out of a DBIC model, (b) pass a subref to a DBIC model to return a $dbh from elsewhere (this works in plain DBIC as well but I figure you care more about the cat case). Between the two it's pretty much always possible to mix and match DBIC and legacy/specialised stuff and still have a single DB connection. But hell, if it works for now, sorted :D -- Matt S Trout Need help with your Catalyst or DBIx::Class project? Technical DirectorWant a managed development or deployment platform?
