Rails versioning with point-in-time query -


is there rails 3 model versioning plugin supports point-in-time queries (not recovery) in sql database?

to concrete: have table, documents. want able say, "as of 9/17/2010, documents contained text 'foo'?". requirement seems rule out of single-table versioning solutions vestal_versions, , none of other ones seem have feature either. of plugins i've looked @ documented black boxes, perhaps store enough data internally sort of query never know docs. in terms of changing dimensions, type 2 sort of solution i'm looking for, although i'll use whatever works.

i need keep track of user made changes, although that's possible outside of versioning system too.

is there 1 i'm missing? or using wrong search term? or roll own?

i think roll own. if need able perform queries on versions, versions should own model, , making versioning gem bend fit needs more painful doing yourself.

sorry, , have fun :/
