DBIx::Class::Helper::ResultSet::VirtualView(3pm) User Contributed Perl Documentation DBIx::Class::Helper::ResultSet::VirtualView(3pm)NAME
DBIx::Class::Helper::ResultSet::VirtualView - Clean up your SQL namespace (DEPRECATED)
VERSION
version 2.013002
SYNOPSIS
# note that this is normally a component for a ResultSet
package MySchema::ResultSet::Bar;
use strict;
use warnings;
use parent 'DBIx::Class::ResultSet';
__PACKAGE__->load_components('Helper::ResultSet::VirtualView');
# and then in code that uses the ResultSet Join with relation x
my $rs = $schema->resultset('Bar')->search({'x.name' => 'abc'},{ join => 'x' });
# 'x' now pollutes the query namespace
# So the following works as expected
my $ok_rs = $rs->search({'x.other' => 1});
# But this doesn't: instead of finding a 'Bar' related to two x rows (abc and
# def) we look for one row with contradictory terms and join in another table
# (aliased 'x_2') which we never use
my $broken_rs = $rs->search({'x.name' => 'def'});
my $rs2 = $rs->as_virtual_view;
# doesn't work - 'x' is no longer accessible in $rs2, having been sealed away
my $not_joined_rs = $rs2->search({'x.other' => 1});
# works as expected: finds a 'table' row related to two x rows (abc and def)
my $correctly_joined_rs = $rs2->search({'x.name' => 'def'});
DESCRIPTION
This component is will allow you to clean up your SQL namespace. See "NOTE" in DBIx::Class::Helper::ResultSet for a nice way to apply it
to your entire schema.
DEPRECATED
This component has been suplanted by DBIx::Class::ResultSet::as_subselect_rs. In the next major version(3) we will begin issuing a
warning on it's use. In the major version after that(4) we will remove it entirely.
METHODS
as_virtual_view
Act as a barrier to SQL symbols. The resultset provided will be made into a "virtual view" by including it as a subquery within the from
clause. From this point on, any joined tables are inaccessible to ->search on the resultset (as if it were simply where-filtered without
joins). See "SYNOPSIS" for example.
NOTE
You don't have to use this as a Component. If you prefer you can use it in the following manner:
# in code using ResultSet:
use DBIx::Class:Helper::VirtualView;
my $new_rs = DBIx::Class::Helper::VirtualView::as_virtual_view($rs);
THANKS
Thanks to ijw from #dbix-class for the idea for this helper (originally called seal), most of the code, and most of the documentation.
