Thanks! I notice that the mongo goodies such as Array and Javascript are commented out. I am assuming that this is because there are no corresponding Persist datatypes to go with those. Is there a plan to add them, or do we want to create some notion of an extended datatype set? On Sat, Mar 26, 2011 at 3:24 PM, Greg Weber wrote:

it compiles. The barrier for me is running the test suite- I have problems so switched it to use cabal-test. But cabal-test can't build the test suite. I have a ticket open with cabal for this.

I hear rumor of a persistent-mongo. I've found http://hpaste.org/fastcgi/hpaste.fcgi/view?id=25669 but is there a more current version?

I helped build the haskell mongodb driver which became the official one, so I know a few things about it. Also, I have some data structures to store for my website and would really prefer not to put them into a relational database.

If there is a more current version of the code, could I take a crack at polishing it up?

Thanks, Rick

I really haven't given much thought to it yet- was waiting for the need to arise. I didn't think it would be a hard problem to support all of the Mongo types, but supporting embedded documents might be.

Embedded documents are just key/val maps of the same simple datatypes. Data.Map would be sufficient to support documents, I have no idea what it would take to support that in a Model definition though :) Arrays in Mongo are the same map objects, but the upside is that we can represent those within Persistent as lists. I should probably learn how Persistent works, so I might take a whack at adding that support. No promises though :)
