NAME

       PGObject::Simple::Role - Moo/Moose mappers for minimalist PGObject framework

VERSION

       Version 1.12.0

SYNOPSIS

       Take the following (Moose) class:

           package MyAPP::Foo;
           use PGObject::Util::DBMethod;
           use Moose;
           with 'PGObject::Simple::Role';

           has id  => (is => 'ro', isa => 'Int', required => 0);
           has foo => (is => 'ro', isa => 'Str', required => 0);
           has bar => (is => 'ro', isa => 'Str', required => 0);
           has baz => (is => 'ro', isa => 'Int', required => 0);

           sub get_dbh {
               return DBI->connect('dbi:Pg:dbname=foobar');
           }
           #  PGObject::Util::DBMethod exports this
           dbmethod int => (funcname => 'foo_to_int');

       And a stored procedure:

           CREATE OR REPLACE FUNCTION foo_to_int
           (in_id int, in_foo text, in_bar text, in_baz int)
           RETURNS INT LANGUAGE SQL AS
           $$
           select char_length($2) + char_length($3) + $1 * $4;
           $$;

       Then the following Perl code would work to invoke it:

           my $foobar = MyApp->foo(id => 3, foo => 'foo', bar => 'baz', baz => 33);
           $foobar->call_dbmethod(funcname => 'foo_to_int');

       The following will also work since you have the dbmethod call above:

           my $int = $foobar->int;

       The full interface of call_dbmethod and call_procedure from PGObject::Simple are
       supported, and call_dbmethod is effectively wrapped by dbmethod(), allowing a declarative
       mapping.

DESCRIPTION

ATTRIBUTES AND LAZY GETTERS

   _get_registry
       This is a method the consuming classes can override in order to set the registry of the
       calls for type mapping purposes.

   _get_schema
       Returns the default schema associated with the object.

   _get_prefix
       Returns string, default is an empty string, used to set a prefix for mapping stored
       prcedures to an object class.

   _get_dbh
       Subclasses or sub-roles MUST implement a function which returns a DBI database handle
       (DBD::Pg 2.0 or hgher required).  If this is not overridden an exception will be raised.

   call_procedure
       Identical interface to PGObject::Simple->call_procedure.

       This can be used on objects or on the packages themselves.  I.e.
       mypackage->call_procedure() and $myobject->call_procedure() both work.

   call_dbmethod
       Identical interface to PGObject::Simple->call_dbmethod

       This can be used on objects or on the packages themselves.  I.e.
       mypackage->call_dbmethod() and $myobject->call_dbmethod() both work.

REMOVED METHODS

       These methods were once part of this package but have been removed due to the philosophy
       of not adding framework dependencies when an application dependency can work just as well.

   dbmethod
       Included in versions 0.50 - 0.71.

       Instead of using this directly, use:

          use PGObject::Util::DBMethod;

       instead.  Ideally this should be done in your actual class since that will allow you to
       dispense with the extra parentheses.  However, if you need a backwards-compatible and
       central solution, since PGObject::Simple::Role generally assumes sub-roles will be created
       for managing db connections etc.  you can put the use statement there and it will have the
       same impact as it did here when it was removed with the benefit of better testing.
