DBIx::Class::Schema::Loader::RelBuilder(3p)

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' => [
          # ...
      ],
      # ...
  }
