DBIx::Class::Helpers::Util - Helper utilities for DBIx::Class components

SYNOPSIS

use DBIx::Class::Helpers::Util ':all';

}

if (assert_similar_namespaces('MyApp::Schema::Result::Person', 'FooApp::Schema::Result::People')) {

}

# in a resultset

DESCRIPTION

A collection of various helper utilities for DBIx::Class stuff. Probably only useful for components.

EXPORTS

order_by_visitor

This function allows you to easily transform order_by clauses. See "SYNOPSIS" for example.

get_namespace_parts

Returns the namespace and class name of a package. See "SYNOPSIS" for example.

is_load_namespaces

Returns true if a package is structured in a way that would work for load_namespaces. See "SYNOPSIS" for example.

is_not_load_namespaces

Returns true if a package is structured in a way that would not work for load_namespaces. See "SYNOPSIS" for example.

assert_similar_namespaces

Dies if both packages are structured in the same way. The same means both are load_namespaces or both are not. See "SYNOPSIS" for example.

normalize_connect_info

Takes all of the various and interesting forms that can be passed to connect and normalizes them into the final and simplest form, a single hashref.
