31 DBIx::Class::Schema::Loader::RelBuilder - Builds relationships for DBIx::Class::Schema::Loader
35 See L<DBIx::Class::Schema::Loader> and L<DBIx::Class::Schema::Loader::Base>.
39 This class builds relationships for L<DBIx::Class::Schema::Loader>. This
40 is module is not (yet) for external use.
46 Arguments: $loader object
53 [ local_moniker1 (scalar), fk_info1 (arrayref), uniq_info1 (arrayref) ]
54 [ local_moniker2 (scalar), fk_info2 (arrayref), uniq_info2 (arrayref) ]
58 This generates the code for the relationships of each table.
60 C<local_moniker> is the moniker name of the table which had the REFERENCES
61 statements. The fk_info arrayref's contents should take the form:
65 local_table => 'some_table',
66 local_moniker => 'SomeTable',
67 local_columns => [ 'col2', 'col3' ],
68 remote_table => 'another_table_moniker',
69 remote_moniker => 'AnotherTableMoniker',
70 remote_columns => [ 'col5', 'col7' ],
73 local_table => 'some_other_table',
74 local_moniker => 'SomeOtherTable',
75 local_columns => [ 'col1', 'col4' ],
76 remote_table => 'yet_another_table_moniker',
77 remote_moniker => 'YetAnotherTableMoniker',
78 remote_columns => [ 'col1', 'col2' ],
83 The uniq_info arrayref's contents should take the form:
87 uniq_constraint_name => [ 'col1', 'col2' ],
90 another_uniq_constraint_name => [ 'col1', 'col2' ],
94 This method will return the generated relationships as a hashref keyed on the
95 class names. The values are arrayrefs of hashes containing method name and
99 'Some::Source::Class' => [
100 { method => 'belongs_to', arguments => [ 'col1', 'Another::Source::Class' ],
101 { method => 'has_many', arguments => [ 'anothers', 'Yet::Another::Source::Class', 'col15' ],
103 'Another::Source::Class' => [
