That one seems to use as explicit "view" at the end of the url instead 
of having the identifier be the last piece of the url.

[Catalyst] Switching between different databases during a session

[Andrew Peebles]

I've been searching and experimenting and have not found a solution ...

I have multiple instances of a database (each in a separate sqlite db 
file), same schema, different data.  Each represents a snapshot of 
something at a particular time.  During a session, user wants switch 
among these databases.  I am trying to add a method to my Model 
(Catalyst::Model::DBIC::Schema) that takes a new connection string, and 
switches to that database ... all things otherwise remaining the same.  
Seems relatively simple, but I just ain't getting it.  Lots of hints on 
the list, but nothing I can find that's helping.


I've tried a lot of variants on something like this:

package SMART::Model::SMARTDB;

use strict;
use base 'Catalyst::Model::DBIC::Schema';

my $dsn = $ENV{MY_DSN} ||= 
'dbi:SQLite:/auto/project/tools/metadot/html/cgi/SMART/smart.db';


__PACKAGE__->config(
   schema_class => 'SMARTDB',
   connect_info => [
   $dsn,
   '',
   '',
   {AutoCommit => 1},
  
   ],

);

sub switch {
   my $self = shift;
   my $dsn  = shift;

   my $connect_info = [ @{$self->{connect_info}} ];
   $$connect_info[0] = $dsn;

   my $schema = $self->clone();
   $schema->connection(@$connect_info);
   $self->schema($schema);
}

Re: [Catalyst] Switching between different databases during a session

[James R. Leu]

I've implemented something along the lines of what your doing, but to
suite a slightly different purpose.

Instead of searching different databases based on time I need to take
one query and run it against a dynamic list of databases and return the
results as one resultset.  The list of databases is determined by users
permissions.

I'll give you an overview of how I did it, and you can decide if it will
work for you.  I got the starter info about how to do this from the
people on this list.

I've created 'template' DBIx modules that inherit from DBIx::Class.
These are standard DBIx::Class definitions except the table
name is a sprintf format, and I register a 'source_name'

I've defined 'template' Catalyst Models that inherit from
Catalyst::Model::DBIC::Schema and list the source_name's from
'template' DBIx modules as the schema_class's.  I then include the
connect_info which for me is standard, but this could be 'templated' too.

I've created a module called Catalyst::Model::Multi.  This module
has logic for registering 'child' models, and then mapping standard
resultset operations to each of the registered children and aggregating
the results.  Much of he code is spent trying to do standard resultset
stuff in a way that makes sense with multiple resultset to pull from.

I have a parent model in my application that inherits from
Catalyst::Model::Multi. In the COMPONENT method I build the full list
of 'child' models that might be needed by individual sessions.
The COMPONENT method is called during application start up, so I build
the full list just one, and each request refers to that list. The
child models are build by calling MyApp::Model::FooDB->COMPONENT($c)
where FooDB is the name of one of the 'template' Catalyst Models.  I
then dig through schema and sources of this model replacing table names
(by using the sprintf formats). I believe you could change the connection
info at this time as well.  I then register these instance of the
'template' Catalyst Model as children of my parent, using a unique name.

During authentication process for a session I build he list of unique names
for child models that will be needed by the session.

As each request comes in ACCEPT_CONTEXT is called on the parent model.
For that request I pull the list of unique names from the session
data and register them with the parent model as where to look when
I make queries to that parent mode for this session.

In my application I refer only to the parent model, never the 'template'
Catalyst Models.

My guess is you could use a similar scheme but instead of using my
Catalyst::Model::Multi, you'd write your own that knows how to
query the various model based on time.

why not have a different Model class for each db?

  

There could be an arbitrary number of them, databases are added over
time.  They are identical; same schema, tables, et. al (same model).

Re: [Catalyst] PathPart help

[Les Fletcher]

I am using

__PACKAGE__->config->{ namespace } = 'foo';

sub obj_setup :  PathPart('') CaptureArgs(1) {}
sub create_setup : PathPart('') CaptureArgs(0) {}

sub view : PathPart('') Chained('obj_setup') Args(0) {}
sub edit : PathPart('') Chained('obj_setup') Args(0) {}
sub create : PathPart('create') Chained('create_setup') Args(0) { }

The thing I don't understand is that when the Chained actions are 
printed out, it gives me the correct actions as I would expect them.  
The create one just doesn't get matched.

Someone correct me if I'm wrong, but I don't believe PathPrefix is in a
release yet...only current source, which is probably going to be 5.9.

I still, as of the latest release on CPAN, have to add the PathPrefix
attr parsing sub.

Re: [Catalyst] PathPart help

[Ashley Pond V]

Now the difference with the path prefix stuff is lost to me.

This fixes the root namespace issue (seems obvious now) and works like
the path prefix is supposed to.

__PACKAGE__->config( namespace => 'a' )

What finer point am I missing? You're right, it's not in the
release yet, just the trunk.

Is it fuck.

It's now a 2* hit rather than a 30* hit but the brain-damage is still there,
at least according to Jon Schutz's last benchmark of a couple weeks back.

What version of DateTime::Locale do you guys have?

0.32 had a bug in it that didn't play nice with storable, so make sure you
have the latest.

Yes, and yes.

It's a per-query cache; if you'd care to write code that provides scalable
logic to provide a reverse index and know which queries' caches to clear
after any given statement I'd be happy to incorporate it, but without that
you'd have to clear every query for any table touched, which would pretty
much defy the point of having a cache for any site with significant updates.

Get resultset object. Then

$rs->cursor->clear_cache; # deletes data from cache

I have the exact same issue. I'm storing my user/roles object data hash
in session, and get the same warning all over the place. Annoying as hell.

Indeed, if I swap out the DateTime objects for strings before stuffing
then in the session, the warnings go away.

So yes, I see it too. :-)

[Catalyst] Storing DateTime in session causes warning

[Tobias Kremer]

I'm storing a DateTime object in $c->session and I just realized that this
is causing the following warning on every request:

"Use of uninitialized value in subroutine entry at ../../lib/Storable.pm
(autosplit into ../../lib/auto/Storable/_freeze.al) line 290."

The following reproduces the error for me:

$c->session->{ 'mydate' } = DateTime->new( year => 2007 );

(for instance in the auto method of the Root controller)

Can somebody confirm this? Any ideas on what's going on and how to fix it?

Wow, I didn't know this either. Looks promising! Is it considered
stable and in production use at Takkle?

I'd also like to know, if it's possible to invalidate the cache after an
update or insert with Cursor::Cached?
