I don't see how it's useful to anyone in its current form, and some of the
refactoring work being done in a branch is being made much harder due to
it's existence.
If you're using this feature in a real application, please shout at me!!
We're using 1) search_extra = [ 'MyAppX' ], as an add-on, non core
namespace 2) {setup_components}-{except} 3) an around 'locate_components'
to filter components in a special mode (which is used under a special flag
which is not being really as far as I remember).
if( $ENV{YELLOW_VERSION} ) {
around 'locate_components' = sub {
my $orig = shift;
grep !/Blue/, $orig-( @_ );
};
}
Just like Stephen, I'd say that the 'except' part could be thrown into the
locate_components wrap, which is already doing filtering. But I'm not sure
about search_extra... that could mean running Module::Pluggable again on the
same directories already scanned by the first Catalyst instance (but now
looking for 'MyAppX' packages), unless we could hook into Catalyst's own
Module::Pluggable somehow.

Re: [Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
I noticed, the Autocomplete plugin waits for String-Array or Object-Array,
(which
starts and ends with [ ...] ) but my code always starts and ends with {
... } (JSON object type).
I tried many perl data-structure, but always starts with { ...
Original working response (with HTML header):
[ { id: Acrocephalus agricola, label: Paddyfield Warbler, value:
Paddyfield Warbler } ]
My not woking response with JSON header:
{value:Common Shelduck,id:Tadorna tadorna,label:Common Shelduck}
Have you tried this?
sub request : Local {
my ($self,$c) = @_;
$c-stash-{json} = [ { id=Acrocephalus agricola, label= Paddyfield
Warbler, value= Paddyfield Warbler } ];
$c-forward('View::JSON');
}
It gives me back the following response:
$ curl http://localhost:3000/request http://localhost:3000/test
[{value:Paddyfield Warbler,id:Acrocephalus

Which works with JQuery's autocomplete example just fine

Re: [Catalyst] Login as another user ...
What's the best way to achieve this? I tried $c-authenticate without a
password, but this doesn't seem to work.
--
I use 2 different authentication realms, ldap (normal login) and none
(single-signon, surrogate) and my login controller decides which one to use,
so that root can surrogate as some other user.
if( $single_signon_user || $surrogate_ok ) {
$c-authenticate({ id=$id }, 'none');
} else { # normal signon
$c-authenticate({ id=$id, password=$password }, 'ldap');
}
And I havethe follwoing in myapp.conf:
authentication
default_realm ldap
realms
none
credential
class password
password_field password
password_type none
/credential
store
class null
/store
/none
ldap
. . .
/ldap
/realms
. . .
/authentication
The bad part is that you can't rely on $c-user for your user data. The user
object will have different data/methods depending on the realm used. So I
use a MyAppUser class that abstracts that, providing the user data
independent from the realm used.
You can also inherit from the Authentication classes and do your own thing
in there, such as ignore the need for a password. But I found the realm
strategy easy and independent. Besides I often use 4 or 5 auth different
realms simultaneously...

Re: [Catalyst] Fat Model Methodology?
Then, just define an extra type that corresponds to a Moose type, or
just some basic rules (varchar/char = Str, etc)
How about a metaclass? That way I could add DBIC metadata to my attributes.
Like this:
has 'name' = (
metaclass = 'DBIC',
is= 'rw',
isa = 'Str',
dbic = { data_type = 'varchar', size = 50, ... }
);
The Moose class would probably need to inherit from DBIx::Class somehow, so
I can set the table name. But I guess this is just the opposite (use DBIC in
Moose) from what you're suggesting (use Moose in DBIC).

The Moose class will implement all complex calculations and validations, and proxy for the bare basic DBIC one. The decoupling is certainly beneficial, but the attribute redundancy bugs me nonetheless. So ideally I would like to have DB entities represented by a single Moose class, rather than in 2 or more places.

Re: [Catalyst] Splitting up a large application: Shared config and templates for multiple applications
Anyone building applications out of multiple small Catalyst applications like this? How do you set up the apps to share templates and a config? Anything more interesting than passing in paths? I have a working module called CatalystX::Featurizer that I've been using in an app at $work. It's still at a very early stage, but I'm just going to push early. No POD included, no tests... You've been warned. :D http://github.com/rodrigolive/catalystx_featurizer It's a mix of Eclipse features/plugins and RoR plugins. Ideas are welcome. I have many myself... just don't have time to implement them all right now. Since there is no POD, I've included a very simple TestApp. Basically the idea is: - create a /features directory under your app home. - each feature home dir should be named something like /features/my.demo.feature_1.0.0 - it's a split on underscore _, the first part is the feature name (very javaish, I know, with dots and all), the second is the version. - if a higher version of a feature is found, that's the one to be used, the rest is ignored - a feature without a version is ok, it will be the highest version available - good for local dev and pushing to a repository. - a debug box is printed on startup, so you can check which version is running: [debug] Features Loaded: .++--. | Feature Name | Class | Version | +++--+ | simple.feature_1.0.0 | simple.feature | 1.0.0 | .-+--. - the idea is to merge /root dirs (right now for Static::Simple, TT and Mason) - controllers, models, schema, etc. should work just like when underneath MyApp/lib - simple.feature.conf is loaded as part of the main conf (appended) - the filename has to match the feature class name, ie simple.feature. - extend the main app part by part (depending on your needs), replacing the standard plugin with an extended one: use Catalyst qw/-Debug +CatalystX::Featurizer this one is a must, loads features and push things into @INC +CatalystX::Featurizer::Plugin::ConfigLoader - optional +CatalystX::Featurizer::Plugin::Static::Simple -- optional /; - I'm also including CF::View::Mason and CF::View::TT. To use them, just subclass it in your MyApp::View::TT or Mason, instead of the C::V::TT,Mason. - a CF::Plugin::I18N is included too. - $c-features returns an array of CF::Feature objects that can be used to identify features, etc. Let me know what you think. cheers -rodrigo ___ 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] passwordless LDAP authentication
Hi all,
I'm using Catalyst::Authentication::Store::LDAP to authenticate users, but
now I need to allow some of them to single-signon without a password, like
this:
if( $is_sso ) {
$c-authenticate({ id= $user }); ## I trust this dude, so skip the
check_password sub
} else {
$c-authenticate({ id= $user, password=$password ); ## old fashioned
}
I'm looking at the authentication internals and it seems to be missing a
per-user flag to disable password checking. Only a global realm-based
password_type='none' exists. Am I correct?
On the other hand, switching realms to a passwordless LDAP where
password_type='none' either duplicates information sensesly, or is a little
bit messy since it needs a MyApp.pm startup config hack. But it seems like
the only doable option right now.
To make matters worse, LDAP::User::check_password also checks user roles
since it needs the password to bind to the ldap server. That could make it
more difficult to implement a passwordless flag at any level on the
authenticate chain.
Any views on this?
regards,
rodrigo

[Catalyst] featurizing a catalyst app
Hi all,
I have an application that has many features (or plugins, or extensions,
or bundles, or whatever, but I'll call it feature for uniqueness sake),
which are subsets of the app that may or may not be bundled into the
application, depending on the customer it will be shipped to.
What I'm looking for is to have a very Eclipse-like directory structure:
MyApp/features/my_first_feature_1.0.0/root/
MyApp/features/my_first_feature_1.0.0/lib/Controller
MyApp/features/my_first_feature_1.0.0/lib/Model
MyApp/features/my_first_feature_1.0.0/lib/View
MyApp/features/another_feature_1.2.0/root/
MyApp/features/another_feature_1.2.0/lib/Controller
MyApp/features/another_feature_1.2.0/lib/Model
MyApp/features/another_feature_1.2.0/lib/View
The idea is that modules contained in features should not be aware that they
are in a feature, but work like they are in the default /lib or /root.
I think the /lib part can probably be setup using this:
__PACKAGE__-config( setup_components = { search_extra = [ @features ] }
);
With a little bit of code to fillup @features correctly, and some @INC
tweaking...
But how about the /root part? Can mixed-up root dirs be seen as a single
root dir easily?
cheers,
rodrigo

Re: [Catalyst] New restarter code in Catalyst::Devel 1.14_01
I did test this on WinXP using Strawberry (5.8.8, IIRC), and it worked
fine. Win32 Perl does support a fork emulation that uses thread under the
hood.
Strange. I'll try it with a different/older version of Strawberry Perl and
see what happens.
I don't think the fork implementation in Strawberry is any different than
ActivePerl. ActiveState wrote the fork implementation (again, IIRC) and
contributed it to the Perl core.
Their forks seem to behave slightly different (it's a feeling more than a
fact), even though I agree that the code is probably the same one Microsoft
helped develop originally. The compilers are different though, VisualStudio
vs MinGW.
That said, I was thinking it might be good to also have a threads-based
version available, and that could be the default to use on Win32.
I took a stab at doing this at one point, but got stuck on trying to
actually kill the child thread.
Since I needed to have the restarter working badly on that machine in
particular, I quickly patched the code with Proc::Background. Something like
this:
sub _fork_and_start() {
my $proc = new Proc::Background(perl $0); # I'm writing this from
memory; not this exactly, there were more args...
my $pid = $proc-pid;
...}
It did the job since the background process was a non-restarter dev server.
And the restarter was able to kill it just fine when changes were detected
because $pid is a real os pid.
I think I put threads / async { } somewhere in there before using
Proc::Background but I got an error... and don't recall which. Killing the
thread requires it to die from the inside, sending it a signal of some sort.
Couldn't the restarter be subclassed then changed in myapp_script.pl through
an %ENV variable?

my $r = BiblioList-model($model)-search()-first();
$ROrgs-{$db} = $r;
}
Emmanuel, make sure that GenoList::$db::Organism actually resolves to a
correct model name for you application. I have a feeling that it doesn't.
Make sure you understand the way DB models are invoked in Catalyst.
Typically:
$c-model('MyModelName::MyResultClassName');
Where:
- ModelName is a module called lib/MyApp/Model/MyModelName.pm
- ResultClassName (usually points to a db table) is a module called
lib/MyApp/Schema/Result/ResultClassName.pm
The paths may vary sensibly depending on how you created them and if it's a
DBIC schema or something else, but hopefully you get the idea.
There's good reading material on this here:
http://search.cpan.org/~hkclark/Catalyst-Manual-5.7021/lib/Catalyst/Manual/Tutorial/MoreCatalystBasics.pod#Create_Static_DBIx::Class_Schema_Files
Couldn't instantiate component BiblioList::Model::Mapping, Can't

line 28. at script/bibliolist_server.pl line 66
Compilation failed in require at script/bibliolist_server.pl line 66.
The method -search() is being called on an undefined value probably
because Catalyst could not find a model for the parameter you passed to
BiblioList-model('...').
If I use $self instead of BiblioList the error change:
Couldn't instantiate component BiblioList::Model::Mapping, Can't
locate object method model via package
BiblioList::Model::Mapping at

Compilation failed in require at script/bibliolist_server.pl line 66.
Don't use $self. The model method hangs from your application object, which
is $c not $self.
$self points to an instance of you BiblioList::Model::Mapping, which is a
child of Catalyst::Model, which does not give you a -model() method.

Re: [Catalyst] How and where to run a method at Catalyst start up?
The strange thing is that if I copy the body of BUILD to
BiblioList.pm (just after __PACKAGE__-setup())
The function works just fine and I don't get any error.
Strange indeed.
Just try, as a possible workaround, just get rid of the GenoList level in
your Model. That would shorten the model call to something like
MyApp-model('bovisR1db::Organism'). See if that works.

Re: [Catalyst] New restarter code in Catalyst::Devel 1.14_01
Restarting is also much faster. All of the Catalyst core code is preloaded in a parent process, and the server runs in a child. That means that when the child is killed and a new child spawned for a new server, it does not need to load all that Catalyst code again, just your application. I'm getting a misbehaving action dispatcher with the new restarter, even before the app is restarted: C:\ catalyst MyApp C:\MyApp perl script\myapp_server.pl -r ... [info] MyApp powered by Catalyst 5.80003 You can connect to your server at http://localhost:3000 The response to the first request to http://localhost:3000 is this: [info] *** Request 1 (0.333/s) [-2208] [Mon May 18 17:02:38 2009] *** [debug] GET request for / from 127.0.0.1 [debug] Couldn't forward to command //_DISPATCH: Invalid action or component.

This is a fresh Strawberry Perl 5.8.9 (Apr 2009) install + Catalyst::Devel. Has anyone tested the new restarter on Win32? It looks like some kindda issue with the fork at Catalyst::Restarter::_fork_and_start(). IMHO, a parent process loaded with the core code could too advanced for windows' pseudo-fork. So I was wondering if maybe this was tested on ActivePerl --I've feeling that their fork works better than Strawberry's. -rodrigo ___ 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/

The idea is to check and create some kind of a data structure that

Create a model for it.
$ script/myapp_create.pl model MyData
Then create the data structure in Model/MyData.pm:

Then call it from any controller:

But how can I access my database within MyApp.pm ?
I tried (in MyApp.pm):
If don't have $c defined, you can use MyApp-model() most of the time.

Re: [Catalyst] Passing connection info to an custom model/external lib
The thing is I realized that if I connect to this schema outside of the scope of Catalyst via DBIx::Class::Schema-connect I have to pass in the connection info separately which really bugs me because I've already defined it via a configuration file for the Catalyst app (using Config::General). I suppose I could just pass that info into the model but that seems messy and redundant to me. To me it doesn't seem messy to parse myapp.conf from your non-catalyst app using Config::General-getall, then pass the connect_info data to your DBIC::Schema class. Besides, you can use your MyApp::Schema classes from anywhere, in case you created them with DBIC::Schema::Loader.

Re: [Catalyst] General Web- and OO-question
My questions:
a) Where do I store the intermediate values of the attributes. I can't put
them in the object itself
as it would generate a invalid object. Do I store them simply as data
somewhere else? Do
I have to create a proxy object with lighter rules?
I wouldn't. Just instantiate your object at the entry controller and store
the instance in the $c-session, or wherever you find appropiate depending
on the object characteristics and the kind of state handling you need.
Do your entry validation as part of the attribute checking validation, as in
Moose:
package MyClass;
use Moose;
use Moose::Util::TypeConstraints;
subtype 'AcceptedAge' = as 'Int' = where { $_ = 16 } = message { 'You
must be at least 16 to use this.' };
subtype 'NameStr' = as 'Str' = where { length($_) 1 } = message { What
kinda name is '$_'? };
has 'name' = (is='rw', isa='NameStr', required = 1 );
has 'age' = (is='rw', isa='AcceptedAge', required = 1 );
has 'sex' = (is='rw', isa='Str', required = 1 );
In your (overly-simplified) controller:
sub submit : Local {
$c-session-{obj} = new MyClass( $c-req-params ); # dies if
constraint fails, so trap errors
}
b) How can I verify attribute rules as early as possible in that entering
process? Do I have to
dublicate the knowledge of the rules outside the class? (e.g. Length of
String attribute less than 20)
The class itself would check such a restriction.
Then, just finish validating your object in the exit controller.
sub wrap_it_up : Local {
...
if( $c-session-{obj}-validate ) {
## yup
} else {
## nope
}
}
Back in your class, do the more complex validations:
sub validate {
return 1 if( ( $self-sex eq 'F' $self-age =16 ) ## girls
mature earlier...
|| ( $self-sex eq 'M' $self-age =18 ) );
}
What ways are you going? Which is the right OO-way of doing it?
TIMTOWTDI
At the moment I really don't know where to place the input validation
knowledge and where and how
to store the partly created objects. I hope it sounds not to academic, but
I want to clearly seperate
the responsibilities.
Moose will give you a lot of ammo to help you with this, things such as
coersion and roles. Check with the moosers in their maling list for further
OO questions.
On the other hand, if you need client-side validation, take a peek at
HTML::FormFu, as it may help you with putting some of those rules on the
client side. Catalyst::Model::Adaptor may also come in handy if you feel you
need to turn your class into a model.

Re: [Catalyst] General Web- and OO-question
But that' s my problem: One one web page I do not get all attributes I need
to instantiate the object correctly. Simple unrealistic example. One one
page
the user can enter a name on the second the age. The object can be
instatiated
if you provide a valid name and age.
Well, just instantiate an empty object then use the accessors Moose creates
for you automagically. Accessors validate as well:
sub start_up : Local {
$c-session-{obj} = new MyClass();
}
sub submit_name : Local {
$c-session-{obj}-name( $c-req-params-{name} );
}
sub submit_age : Local {
$c-session-{obj}-age( $c-req-params-{age} );
}
But I can't instatiate
the object because it throws an exception because age is not valid, isn't
it?
Or does Moose check constraints only on provided attributes. This can't be
true
with required attributes, can it?
As long as the attribute is not required = 1, no exception is thrown.
Catalyst::Model::Adaptor may also come in handy if
you feel you need to turn your class into a model.
What do you mean with that?
First, read up on the Model part of MVC, that's where most of your
application storage should end up. Have you decided what are you going to do
with the object once it's filled up?

Re: [Catalyst] General Web- and OO-question
I think you are missing his point. He wants to instantiate an object from the form, but if he uses his Moose object then the things he wants to validate (errors) will prevent him from getting an instance of his class. If name is required or isa 'Str' then if it gets an arrayref, he can't use the object (as either it missing or being the wrong type throws an exception). Well, if the object gets an arrayref when it was expecting an Str then he can't use the object and it should throw an exception. ___ 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/
Re: [Catalyst] Google Summer of Code: mentors, projects
I have a dream... project. A Catalyst Application Server (i.e. Websphere, Weblogic, JBoss in javaland). It would be a catalyst app for managing and deploying other catalyst apps. It would take care of starting separate perl processes (virtual servers), plug them into Apache/lighttpd config files (fcgi, mod_perl), or maybe even run the app in the same shared perl process where the catalyst app server is running. It would allow developers and admins to manage their apps (start/stop/restart), deploy .par/.tar/.zip files that would then be expanded into the app server directory, setup dbi datasources, have a common security realm, maybe a simple communication layer in between apps, etc. Web-console, web-service and CLI enabled. Well, you get the idea. I think it may appeal to a student to write something like this. It has good visibility. It scales well as a project, it could start as something simple, to fit the Summer of code timeline, then allow for extensions to be writen later. It wouldn't mess with Catalyst internals, which IMO makes it easier to tutor. It's something that would help sell Catalyst as a corporate-wide application infraestructure, or for webserver providers to manage installed apps, or simply for us mortals to manage our scattered cat apps from a central control panel. -rodrigo ___ 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/
Re: [Catalyst] Catalyst on Windows: fork issues
Stefan, I've had similar problems in windows with prefork, which can be started up after some tweaking, but will hang after a few requests. Perl's fork() is a no-no in windows. FCGI can be painful to setup, so I ended up giving up on it. I went on to use mod_perl with Apache, which has problems of its own too, but a more trivial setup. Finally, the approach I'm using right now is to setup a pool of single-threaded Catalyst dev servers, starting them up in a startup.bat such as this: start /b perl script\myapp_server.pl -p 3000 start /b perl script\myapp_server.pl -p 3001 start /b perl script\myapp_server.pl -p 3002 ... If you wish to keep all your logs in one place: startup.bat myapp.log 21 Then setup an Apache mod_proxy load-balancer (or lighttpd's, etc.) to balance the load among dev servers. Make sure you understand the drawbacks of using catalyst dev servers in this manner, even though they work superbly. httpd.conf (or apache2.conf or etc.): LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_balancer_module modules/mod_proxy_balancer.so LoadModule proxy_http_module modules/mod_proxy_http.so Proxy balancer://cat BalancerMember http://localhost:3000 BalancerMember http://localhost:3001 BalancerMember http://localhost:3002 /Proxy ProxyPass / balancer://cat/ ProxyPassReverse / balancer://cat/ Take a look around the web for other settings that you may need, such as catalyst's using_frontend_proxy and apache's static aliases, balancer features, etc. Apache is extremely lightweight if you only run it for reverse proxy load-balancing. If you want to startup your catalyst server pool from a windows service using a configuration file, I have a perl script that does that somewhere. Just let me know.

From this point of view, Perl is not a very good language for Windows because it is hard to adapt the modules that work fine under other systems. I agree that perl and cpan modules favor posix features, such as fork(), and that's a no-go for windows. I just try to avoid those by using no-posix modules.

3) Walkthrough of creation of a simple app end to end. Yes please, a full example tutorial is just what we need! And example apps! As a Catalyst beginner, I craved example apps the most (I still do!). While learning, I find it more productive checking out a small example app by both reading code and doing a run through the interface, rather than big walkthrough tutorials or pod copy-pasting. Also, tiny apps can easily be used as quick-starters for your real apps, sorta like the next step up from Catalyst::Helper modules. The stuff in the wiki and http://dev.catalystframework.org/repos/Catalyst/trunk/examples/ may serve as a starting point. CPAN also hosts some apps, including MojoMojo. And I'm sure we all have many small test apps laying around we can just tarball and share. -rodrigo ___ 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/

I need a something like TheSchwartz::Scheduler, i was thinking in change
TheSchwartz-work method, they will look the time to run a job and execute
the job only when is the rigth time
Does anyone have some tips? I looked at CPAN but dont find anything like
this.
I've been using TheSchwartz::Moosified in my Catalyst app to schedule jobs.
Something along these lines:
package MyApp::Worker;
use base 'TheSchwartz::Moosified::Worker';
sub work {
my ($class, $job) = @_;
print WORKING:. $job-dump();
$job-completed;
}
package main;

use TheSchwartz::Moosified;
my $client = TheSchwartz::Moosified-new( verbose = 1);
MyApp-model('DBIC')-storage-dbh_do(
sub {
my ($storage, $dbh) = @_;
$client-databases([$dbh]) or die $!;
} );
use Date::Manip; Date_Init( TZ=CET);
## schedule a job
my $job = TheSchwartz::Moosified::Job-new(
funcname = 'MyApp::Worker',
run_after= UnixDate(ParseDate('2009-02-12 13:00:00'), '%s' ), ##
run_after expects a secs since epoch value
## you may also wanna set grabbed_until
arg = [ foo = 'bar' ],
);
$client-insert($job) or die $!;
$client-can_do('MyApp::Worker');
$client-work();

Re: [Catalyst] Plugin::Authentication overrides $c-req-user
On Tue, Feb 10, 2009 at 9:46 PM, Daniel Westermann-Clark d...@pobox.comwrote:
Hi,
At work we use, among other things, the value of REMOTE_USER in the
request environment to authenticate users using our single-sign on
system. We access this via $c-req-user, which the various engines
set using the data available to them.
However, Catalyst::Plugin::Authentication-set_authenticate overrides
this value with the blessed user object in addition to setting
$c-user. Looking at the commit logs, it looks like this has been
true since 2005 but I'm having a hard time finding a reason why.
Also, Catalyst::Request lists $c-req-user as deprecated. If it were
to be removed, how would one access the value in an engine-agnostic
way?
I'm not familiar with $c-req-user, but isn't REMOTE_USER a header you can
read with $c-req-header('remote_user'), or whatever header name is being
passed around?

Re: [Catalyst] controller subclass and :Local actions

when I call /myapp/cd/list the base controller's list action gets called...
Can someone give me a hint ?

Strange. That works fine for me. What does the debug output prints out for
the path dispatch table when the server starts up?
It should look something like this:
[debug] Loaded Path actions:
.-+.
| Path| Private|
+-++
| /base/list | /base/list |
| /cd/list| /cd/list |
'-+'

Re: [Catalyst] Catalys TheSchwartz, was Catalyst modperl - child process segmentation fault
This is what I'm using for creating TheSchwartz::Moosified connections from
Catalyst:
use TheSchwartz::Moosified;
my $client = TheSchwartz::Moosified-new();
# this will get you a dbh with DBIx::Class::Storage::DBI exception
handling:
MyCatalystApp-model('MyModel')-storage-dbh_do(
sub {
my ($storage, $dbh) = @_;
$client-databases([$dbh]) or die $!;
}
);
# this also works:
# $client-databases([MyCatalystApp-model('MyModel')-storage-dbh]);
$client-insert( ... );
The advantage is that you won't have to create a new dbh connection
everytime you insert a job, in case that's what you want.
The disadvantage is that I don't know how far the moosified version is
backward compatible with the original TheSchwartz (it has worked fine for me
so far).
cheers,
rodrigo

That reminds me. Does anybody have experience submitting TheSchwartz jobs
from a Catalyst?
TheSchwartz uses it's own system of allocating DB handles, and I have no
idea how it interacts with
Catalyst's.
I *think* I'm safe because I'm not allocating any schwatz connections
until
I'm actually serving a
Catalyst request, but I'd like to hear from anybody who has actual
experience...
I've done quite a bit of work with TheSchwartz and Catalyst.
Catalyst does -nothing- with database handles. Absolutely nothing.
If you use a database, chances are you are using
Catalyst::Model::DBIC::Schema which then uses DBIx::Class.
TheSchwartz uses Data::ObjectDriver for its ORM. The two play just
fine together.
The model class for TheSchwartz is quite simple:
package MyApp::Model::TheSchwartz;
use base 'Catalyst::Model';
use TheSchwartz;
sub COMPONENT {
return TheSchwartz-new( databases = $DATABASE_INFO );
}
1;
From there, you can just do $c-model(TheSchwartz)-insert(...); and
the job will be inserted. Look at the pod for TheSchwartz for the
database info, and the schema for TheSchwartz database is hidden away
in the distribution with no links:
http://search.cpan.org/src/BRADFITZ/TheSchwartz-1.07/doc/
TheSchwartz also fails tests so you have to force install, has
terrible documentation and is generally frustrating to use because of
these superficial shortcomings.
The code itself is sound enough, but the packaging and release is
quite terrible. It will take you some time to sort it out and get
everything running, so good luck. Once it is up and running, it is
quite simple and the API is good.

Re: [Catalyst] Re: Upload problem
Try Google Chrome. It doesn't seem to complain about 4Gb file uploads. Using the Catalyst test server should be fine. Maybe you're pushing the multipart/form-data envelope here.
