NAME
DBIx::Class::Schema::Loader::RelBuilder - Builds relationships for DBIx::Class::Schema::Loader SYNOPSIS
See DBIx::Class::Schema::Loader and DBIx::Class::Schema::Loader::Base. DESCRIPTION
This class builds relationships for DBIx::Class::Schema::Loader. This is module is not (yet) for external use. METHODS
new Arguments: $loader object generate_code Arguments: [ [ local_moniker1 (scalar), fk_info1 (arrayref), uniq_info1 (arrayref) ] [ local_moniker2 (scalar), fk_info2 (arrayref), uniq_info2 (arrayref) ] ... ] This generates the code for the relationships of each table. "local_moniker" is the moniker name of the table which had the REFERENCES statements. The fk_info arrayref's contents should take the form: [ { local_table => 'some_table', local_moniker => 'SomeTable', local_columns => [ 'col2', 'col3' ], remote_table => 'another_table_moniker', remote_moniker => 'AnotherTableMoniker', remote_columns => [ 'col5', 'col7' ], }, { local_table => 'some_other_table', local_moniker => 'SomeOtherTable', local_columns => [ 'col1', 'col4' ], remote_table => 'yet_another_table_moniker', remote_moniker => 'YetAnotherTableMoniker', remote_columns => [ 'col1', 'col2' ], }, # ... ], The uniq_info arrayref's contents should take the form: [ [ uniq_constraint_name => [ 'col1', 'col2' ], ], [ another_uniq_constraint_name => [ 'col1', 'col2' ], ], ], This method will return the generated relationships as a hashref keyed on the class names. The values are arrayrefs of hashes containing method name and arguments, like so: { 'Some::Source::Class' => [ { method => 'belongs_to', arguments => [ 'col1', 'Another::Source::Class' ], { method => 'has_many', arguments => [ 'anothers', 'Yet::Another::Source::Class', 'col15' ], ], 'Another::Source::Class' => [ # ... ], # ... } AUTHOR
