rack_datamapper

DESCRIPTION:

this collection of plugins helps to add datamapper functionality to Rack. there is a IdentityMaps plugin which wrappes the request and with it all database actions are using that identity map. the transaction related plugin TransactionBoundaries and RestfulTransactions wrappes the request into a transaction. for using datamapper to store session data there is the DatamapperStore.

NAMING of the GEM

due to some restrictions on rubyforge I could not use the under score in the gem name, so the gem name is

rack-datamapper

sorry for the confusion this might cause. see also gemcutter.org/search?query=rack-datamapper

DataMapper::Session::Abstract::Store

this is actual store class which can be wrapped to be used in a specific environement, i.e. Rack::Session::Datamapper. this store can the same options as the session store from rack, see
