AutoCRUD revamped

For a couple of years I’ve been planning to rip apart and put back together the guts of Catalyst::Plugin::AutoCRUD, to address limitations in the initial implementation. After changing job and moving house I’m pleased this finally came to the top of my hacking stack.

Nothing was going to happen however before I could work out how to do one thing: achieve independence from DBIx::Class as a “storage engine”. I love DBIx::Class, but it would be much more cool to support any data storage system able to represent a table+column paradigm (even things like CSV, as a test case).

So SQL::Translator hit me like a thunderbolt. Of course, that’s exactly what it does - introspect some data storage and provide a neutral, class-based representation of the tables and columns (fields). It’s a little rough around the edges, but certainly good enough. The Translator provides a metadata structure which AutoCRUD’s web front-end can use, independent of any particular storage engine such as DBIx::Class. This also paves the way for development of display engines other than the bundled ExtJS and simple HTML offerings.

Right now there’s a developer release of AutoCRUD on CPAN, and I hope shortly to have a production release. Whilst the web side might not look much different, the fact is that it can now support significant features such as tables with composite/compound primary keys, or no primary keys for that matter, database views, relations to self, multiple relations to the same table, and so on.

Alongside that, I’ve taken the opportunity to fix a few quirks of the web interface, and chomp my way through the outstanding wishlist. The updated code is now running on a DotCloud instance, so please go and have a play!
