Tie-DBIx-Class
DBIx::Class puts a SQL row into a simple object and
masks all SQL from you scripts, but it's strictly
database based.
Imagine you got a house:
my $house = House->new(1);
$house->open_door();
$house could be a SQL row, but what if you'ld like
to add methods or sub-objects which aren't SQL rows?
Here is what Tie-DBIx-Class is for:
package House;
sub new {
my $class = shift;
my $house_id = shift;
tie(my %row,'Tie::DBIx::Class',$main::schema,'houses',$house_id);
return bless \row,$class;
}
sub open_door {
# Access the door controller
}
Every column is accessible as a hash key of the blessed object
while you're still free to define additional methods.
In addition, Tie::DBIx::Class waits for the first access to
the hash's data before actually fetching the data from the
database - saving resources in case you just want to open the
door and don't need the SQL row's data at all.
Tie::DBIx::Class has been developed for use with
Template::Toolkit. Templates may get access to database rows
without the need to preload everything which might be used by
a template. Just create the objects and push them to
Template::Toolkit and the required rows will be loaded
automatically.
