Class::DBI::Search::Basic.3pm

NAME

Class::DBI::Search::Basic - Simple Class::DBI search

SYNOPSIS

         my $searcher = Class::DBI::Search::Basic->new(
                 $cdbi_class, @search_args
         );
 
         my @results = $searcher->run_search;
 
         # Over in your Class::DBI subclass:
         
         __PACKAGE__->add_searcher(
                 search  => "Class::DBI::Search::Basic",
           isearch => "Class::DBI::Search::Plugin::CaseInsensitive",
         );
 
 

DESCRIPTION

This is the start of a pluggable Search infrastructure for Class::DBI.

At the minute Class::DBI::Search::Basic doubles up as both the default search within Class::DBI as well as the search base class. We will probably need to tease this apart more later and create an abstract base class for search plugins.

METHODS

new

         my $searcher = Class::DBI::Search::Basic->new(
                 $cdbi_class, @search_args
         );
 
 

A Searcher is created with the class to which the results will belong, and the arguments passed to the search call by the user.

opt

         if (my $order = $self->opt('order_by')) { ... }
 
 

The arguments passed to search may contain an options hash. This will return the value of a given option.

run_search

         my @results = $searcher->run_search;
         my $iterator = $searcher->run_search;
 
 

Actually run the search.

SUBCLASSING

sql / bind / fragment

The actual mechanics of generating the SQL and executing it split up into a variety of methods for you to override.

run_search() is implemented as:

   return $cdbi->sth_to_objects($self->sql, $self->bind);
 
 

Where sql() is

   $cdbi->sql_Retrieve($self->fragment);
 
 

There are also a variety of private methods underneath this that could be overriden in a pinch, but if you need to do this I'd rather you let me know so that I can make them public, or at least so that I don't remove them from under your feet.
