package DBIx::Class::Test::SQLite;

=head1 NAME

DBIx::Class::Test::SQLite - Base class for DBIx::Class tests, shamelessly ripped from Class::DBI::Test::SQLite

=head1 SYNOPSIS

	use base 'DBIx::Class::Test::SQLite';

	__PACKAGE__->set_table('test');
	__PACKAGE__->columns(All => qw/id name film salary/);

	sub create_sql { 
		return q{
			id     INTEGER PRIMARY KEY,
			name   CHAR(40),
			film   VARCHAR(255),
			salary INT
		}
	}
	
=head1 DESCRIPTION

This provides a simple base class for DBIx::Class tests using SQLite.
Each class for the test should inherit from this, provide a create_sql()
method which returns a string representing the SQL used to create the
table for the class, and then call set_table() to create the table, and
tie it to the class.

use strict;

use base 'DBIx::Class';
use File::Temp qw/tempfile/;
my (undef, $DB) = tempfile();
END { unlink $DB if -e $DB }

my @DSN = ("dbi:SQLite:dbname=$DB", '', '', { AutoCommit => 1 });

__PACKAGE__->connection(@DSN);
#__PACKAGE__->set_sql(_table_pragma => 'PRAGMA table_info(__TABLE__)');
#__PACKAGE__->set_sql(_create_me    => 'CREATE TABLE __TABLE__ (%s)');

=head1 METHODS

=head2 set_table

	__PACKAGE__->set_table('test');

This combines creating the table with the normal DBIx::Class table()
call.

=cut

sub set_table {
	my ($class, $table) = @_;
	$class->table($table);
	$class->_create_test_table;
}

sub _create_test_table {
	my $class = shift;
	my @vals  = $class->_sql_to_sth(
                      'PRAGMA table_info(__TABLE__)')->select_row;
	$class->_sql_to_sth(
          'CREATE TABLE '.$class->table.' ('.$class->create_sql.')'
            )->execute unless @vals;
}

=head2 create_sql (abstract)

	sub create_sql { 
		return q{
			id     INTEGER PRIMARY KEY,
			name   CHAR(40),
			film   VARCHAR(255),
			salary INT
		}
	}

This should return, as a text string, the schema for the table represented
by this class.
