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

        sub connection {
           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.
