# NAME Catalyst::TraitFor::Model::DBIC::Schema::QueryLog::AdoptPlack - Use a Plack Middleware QueryLog # SYNOPSIS package MyApp::Web::Model::Schema; use parent 'Catalyst::Model::DBIC::Schema'; __PACKAGE__->config({ schema_class => 'MyApp::Schema', traits => ['QueryLog::AdoptPlack'], ## .. rest of configuration }); # DESCRIPTION This is a trait for [Catalyst::Model::DBIC::Schema](http://search.cpan.org/perldoc?Catalyst::Model::DBIC::Schema) which adopts a [Plack](http://search.cpan.org/perldoc?Plack) created [DBIx::Class::QueryLog](http://search.cpan.org/perldoc?DBIx::Class::QueryLog) and logs SQL for a given request cycle. It is intended to be compatible with [Catalyst::TraitFor::Model::DBIC::Schema::QueryLog](http://search.cpan.org/perldoc?Catalyst::TraitFor::Model::DBIC::Schema::QueryLog) which you may already be using. It picks up the querylog from `$env->{'plack.middleware.dbic.querylog'}` or from `$env->{'plack.middleware.debug.dbic.querylog'}` which is generally provided by the [Plack](http://search.cpan.org/perldoc?Plack) middleware [Plack::Middleware::Debug::DBIC::QueryLog](http://search.cpan.org/perldoc?Plack::Middleware::Debug::DBIC::QueryLog) In fact you will probably use these two modules together. Please see the documentation in [Plack::Middleware::Debug::DBIC::QueryLog](http://search.cpan.org/perldoc?Plack::Middleware::Debug::DBIC::QueryLog) for an example. PLEASE NOTE: Starting with the 0.04 version of [Plack::Middleware::Debug::DBIC::QueryLog](http://search.cpan.org/perldoc?Plack::Middleware::Debug::DBIC::QueryLog) we will canonicalize on `$env->{'plack.middleware.dbic.querylog'}`. For now both listed keys will work, but within a release or two the older key will warn and prompt you to upgrade your version of [Plack::Middleware::Debug::DBIC::QueryLog](http://search.cpan.org/perldoc?Plack::Middleware::Debug::DBIC::QueryLog). Sorry for the trouble. # SEE ALSO [Plack::Middleware::Debug::DBIC::QueryLog](http://search.cpan.org/perldoc?Plack::Middleware::Debug::DBIC::QueryLog), [Catalyst::TraitFor::Model::DBIC::Schema::QueryLog](http://search.cpan.org/perldoc?Catalyst::TraitFor::Model::DBIC::Schema::QueryLog), [Catalyst::Model::DBIC::Schema](http://search.cpan.org/perldoc?Catalyst::Model::DBIC::Schema), [Plack::Middleware::Debug](http://search.cpan.org/perldoc?Plack::Middleware::Debug) # ACKNOWLEGEMENTS This code inspired from [Catalyst::TraitFor::Model::DBIC::Schema::QueryLog](http://search.cpan.org/perldoc?Catalyst::TraitFor::Model::DBIC::Schema::QueryLog) and the author owes a debt of gratitude for the original authors. # AUTHOR John Napiorkowski, `` # COPYRIGHT & LICENSE Copyright 2012, John Napiorkowski This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
