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"
