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

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

 my ($namespace, $class) = get_namespace_parts('MyApp:Schema::Person');
 is $namespace, 'MyApp::Schema';
 is $class, 'Person';

 if (is_load_namespaces('MyApp::Schema::Result::Person')) {
   print 'correctly structured project';
 }

 if (is_not_load_namespaces('MyApp::Schema::Person')) {
   print 'incorrectly structured project';
 }

 if (assert_similar_namespaces('MyApp::Schema::Person', 'FooApp::Schema::People')) {
   print 'both projects are structured similarly';
 }

 if (assert_similar_namespaces('MyApp::Schema::Result::Person', 'FooApp::Schema::Result::People')) {
   print 'both projects are structured similarly';
 }

 # in a resultset

 sub search {
    my ($self, $search, $attrs) = @_;

    $attrs->{order_by} = order_by_visitor($attrs->{order_by}, sub {
       my $field = shift;

       return 'foo_bar' if $field eq 'foo.bar';
       return $field;
    }) if $attrs && $attrs->{order_by};

    $self->next::method($search, $attrs);
 }

 # in schema

    my $self = shift;

    my $args = normalize_connect_info(@_);
    $args->{quote_names} = 1;

    $self->next::method($args)
 }

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.
