copied!<p>You're trying to create a Moose class and it's not compatible with the regular <a href="http://metacpan.org/module/Catalyst%3a%3aModel%3a%3aAdaptor" rel="nofollow">Catalyst::Model::Adaptor</a> usage; and you are not, in your example, using any Moose functionality anyway. This is probably, lightly tested, what you really want.</p> <pre><code>package MyApp::Model::TheSchwartz; use parent "Catalyst::Model::Adaptor"; __PACKAGE__->config( class => "TheSchwartz" ); sub mangle_arguments { my ($self, $args) = @_; if ( $args->{databases} ) { if (ref ( $args->{databases} ) eq "HASH" ) { my %db = %{ $args->{databases} }; $args->{databases} = [ \%db ]; } } return %{ $args } } 1; </code></pre> <p><a href="http://metacpan.org/module/parent" rel="nofollow">parent</a> is sometimes considered preferable to <a href="http://metacpan.org/module/base" rel="nofollow">base</a> but they are almost interchangeable.</p> <h3>Update, 26 July 2012</h3> <p>FWIW, this is a working version of TheSchwartz being used as a model in one of my apps; it's been in production for... 2 years I think. The Cat version is a few back but not 2 years old. I'm sorry I didn't dig it up before–</p> <pre><code>package MyApp::Model::TheSchwartz; use parent "Catalyst::Model::Adaptor"; __PACKAGE__->config( class => "TheSchwartz" ); sub mangle_arguments { %{$_[1]} } 1; __END__ # In MyApp.pm "Model::TheSchwartz" => { args => { verbose => 1, databases => [{ dsn => "dbi:mysql:MyAppDB;host=my_host", user => "something", pass => "somethingsecret", }], } }, </code></pre> <p>The <a href="http://metacpan.org/module/Config%3a%3aGeneral" rel="nofollow">Config::General</a> format you're using is probably to blame your ref/HASH handling. You can see from my <code>mangle_arguments</code> that if the args are properly formed, there is no need to do anything with them at all but flatten them to the list TheSchwartz expects.</p>
