[Catalyst] setting up files and namespace for utilizing differentmodels in the same catalyst app

[Hermida, Leandro]

Hello and Happy Thanksgiving,

What if one wanted to use more than one model for the same database?
Sorry to make things difficult, I am a new user and I am trying to
understand the proper way to set up the groundwork for a large project
and I don't want there to be a gotcha or annoyance because I didn't
think something through down the road. So if I wanted to use two models
for the library (for example DBIx::Class and DBI)

Would it be for the database,

MyApp::Library::DBIC::Schema
MyApp::Library::DBI

then for the model,

MyApp::Model::Library::DBIC::Schema
MyApp::Model::Library::DBI

then in code,

$c->model('Library::DBIC::Schema')->resultset('Book')->all;

Etc. ?


I am also very confused about what both you and A. Berlin wrote about
the namespace catalyst or web app.  Maybe I am not far enough yet in the
tutorial?  What did you mean by:

MyApp::Web -> catalyst app

What does this tree of code hold?  It seems so far from the tutorial
that everything goes under MyApp::Model, MyApp::View, or
MyApp::Controller to defined the catalyst app but maybe I am missing
something.

Thank you,

Leandro Hermida

Hello,

I am working through the tutorial and a question came to mind when
looking at the naming conventions used.

For DBIx::Class,

lib/MyAppDB.pm
lib/MyAppDB/Book.pm
lib/MyAppDB/Author.pm
lib/MyAppDB/BookAuthor.pm

Then for the Catalyst model,

lib/MyApp/Model/MyAppDB.pm

and in code,

$c->model('MyAppDB')->resultset('Book')->all;

What would people recommend as a naming convention and namespace setup
if one wanted to 
eventually use more than one model inside of the same Catalyst app?

would it be something like:

For DBIx::Class,

lib/MyApp/DBIC/Schema.pm
lib/MyApp/DBIC/Schema/Book.pm
lib/MyApp/DBIC/Schema/Author.pm
lib/MyApp/DBIC/Schema/BookAuthor.pm

For Catalyst,

lib/MyApp/Model/DBIC/Schema.pm

and in code,

$c->model('DBIC::Schema')->resultset('Book')->all;
