NAME

Test::DBChanges::Pg::DBIC - track changes to DBIC+PostgreSQL resultsets

VERSION

version 1.0.0

SYNOPSIS

my $dbchanges = Test::DBChanges::Pg::DBIC->new({
  schema => $schema,
  source_names => [qw(Things Ledger)],
});

# later:
my $changeset = $dbchanges->changeset_for_code(sub { do_something($dbh) });

for my $row ($changeset->changes_for_source('Things')->inserted_rows->@*) {
   # $row is a MySchema::Result::Things object with the inserted data
}

DESCRIPTION

This class installs a set of triggers in the database, that record all changes (insert, update, delete) to a set of tables.

It can then parse this record into a changeset, which will build DBIC objects corresponding to each changed row.

NOTE: the row objects will not be in_storage (some of them may refer to deleted rows, for example!)

This should really only be used in tests. At the moment the table, stored procedure and triggers that this class needs are installed but never removed.

ATTRIBUTES

source_names

Arrayref of resultset names corresponding to the tables to record changes for.

schema

The connected schema to track changes in.
