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

NAME
DBIx::Class::Schema::Loader::DBI::Writing - Loader subclass writing guide for DBI SYNOPSIS
package DBIx::Class::Schema::Loader::DBI::Foo; # THIS IS JUST A TEMPLATE TO GET YOU STARTED. use strict; use warnings; use base 'DBIx::Class::Schema::Loader::DBI'; use mro 'c3'; sub _table_uniq_info { my ($self, $table) = @_; # ... get UNIQUE info for $table somehow # and return a data structure that looks like this: return [ [ 'keyname' => [ 'colname' ] ], [ 'keyname2' => [ 'col1name', 'col2name' ] ], [ 'keyname3' => [ 'colname' ] ], ]; # Where the "keyname"'s are just unique identifiers, such as the # name of the unique constraint, or the names of the columns involved # concatenated if you wish. } sub _table_comment { my ( $self, $table ) = @_; return 'Comment'; } sub _column_comment { my ( $self, $table, $column_number ) = @_; return 'Col. comment'; } 1; DETAILS
The only required method for new subclasses is "_table_uniq_info", as there is not (yet) any standardized, DBD-agnostic way for obtaining this information from DBI. The base DBI Loader contains generic methods that *should* work for everything else in theory, although in practice some DBDs need to override one or more of the other methods. The other methods one might likely want to override are: "_table_pk_info", "_table_fk_info", "_tables_list" and "_extra_column_info". See the included DBD drivers for examples of these. To import comments from the database you need to implement "_table_comment", "_column_comment" AUTHOR
