NAME

DBIx::Class::Tokenize - Automatically tokenize a column on creation

DESCRIPTION

This component simply creates a clean token based on a field on insertion. The simple use case is having a long name that is displayable, like "Catalyst Book" that you want to change to "catalyst_book". Rather than do that by hand every time you create a record, this component does it for you.

SYNOPSIS

 package MyApp::Schema::Book;

 __PACKAGE__->load_components( qw(Tokenize ... Core) );
 __PACKAGE__->add_columns(
     id   => { data_type => 'integer', is_auto_increment => 1 },
     name => { data_type => 'varchar', size => 128, 
        # Update the 'token' field on create
        token_field => 'token' },
     token => { data_type => 'varchar', size => 128, is_nullable => 0 }
 );

 ...

 my $row = $schema->resultset('Book')->create({ name => "Catalyst Book" });
 
 print $row->token; # Prints "catalyst_book

METHODS

tokenize

This method is what performs the actual conversion to the tokenized form. It is easy to override so that you can change things around to suit your particular table. Whatever is returned is inserted into the configured token_field.

An example of extending this method would be to traverse a tree in a row that uses DBIx::Class::Tree::AdjacencyList and tokenize the parents as well.
