>From helping Chris I've just remembered exactly where I went wrong (and also where he seems to have gone wrong) - which was by using dump_to_dir(), instead of make_schema_at() combined with the dump_directory option. I'd like to take a stab at updating the docs for DBIC::Schema::Loader to make it more obvious which one to use, if people think that would be worthwhile? Currently I think both the method names and the start of the description of make_schema_at() tend to guide you towards dump_to_dir() if you want to generate an on-disk copy of your schema from an existing database, when I think that what most people want in these circumstances* is probably the functionality that make_schema_at() + dump_directory offer. Regards, Denny * I'm not actually sure in what circumstances dump_to_dir _is_ useful, so I may be missing something important here. _______________________________________________ List: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/dbix-class IRC: irc.perl.org#dbix-class SVN: http://dev.catalyst.perl.org/repos/bast/DBIx-Class/ Searchable Archive: http://www.grokbase.com/group/[email protected]
