52 | |
53 | =head1 SYNOPSIS |
54 | |
55 | package MySchema::ResultSet::Person; |
56 | use base qw(DBIx::Class::ResultSet); |
57 | |
58 | __PACKAGE__->load_components(qw(ResultSet::ParameterizedJoinHack)); |

62 | =head1 DESCRIPTION |
63 | |
64 | This is a ResultSet component allowing you to access the dynamically |
65 | parameterized relations declared with |
66 | L<DBIx::Class::ParameterizedJoinHack>. |
67 | |
68 | Enable the component as usual with: |
69 | |
70 | __PACKAGE__->load_components(qw( ResultSet::ParameterizedJoinHack )); |
71 | |
72 | in your ResultSet class. |
73 | |
74 | See L<DBIx::Class::ParameterizedJoinHack> for declaration documentation, |
75 | a general overview, and examples. |
76 | |
77 | =head1 METHODS |
78 | |
79 | =head2 with_parameterized_join |
80 | |
81 | my $joined_rs = $resultset->with_parameterized_join( |
82 | $relation_name, |
83 | $parameters, |
84 | ); |
85 | |
86 | This method constructs a ResultSet joined with the given C<$relation_name> |
87 | by the passed C<$parameters>. The C<$relation_name> is the name as |
88 | declared on the Result, C<$parameters> is a hash reference with the keys |
89 | being the parameter names, and the values being the arguments to the join |
90 | builder. |
