NAME

       Jifty::Model::Metadata - Tracks Jifty-related metadata

SYNOPSIS

         my $app = Jifty->new(config_file => "$ProjectRoot/etc/config.yml");
         my $application_version = Jifty::Model::Metadata->load("application_db_version");

DESCRIPTION

       Every Jifty application automatically inherits this table, which describes information
       about the Jifty database.  It uses this information to smartly upgrade between application
       schema versions, as well as versions of Jifty itself, for instance.

   table
       Each schema is stored in the table "_jifty_metadata".

   since
       The metadata table first appeared in Jifty version 0.60427

   load KEY
       Fetches the given "KEY" from the metadata store.  Returns undef if such a key cannot be
       found.

   store KEY => VALUE
       Stores the given "KEY" in the database, overwriting the previous value if it existed.
