problems importing to mongo from a query

[billieblaze]

so, i've recently switched from the railo mongodb extension to cfmongodb because i'm having problems with my data landing in a proper mongodb format. I'm working on a routine which will perform a CFQUERY against a VisualFoxPro ODBC connection(barf), then stash the records in mongodb. the mongodb data will later be consumed by a nodeJS app. two problems i'm having

1. i was setting _id to a particular field in my db, for example, the old db has a "drivernumber" field, so i was feeding that into _id because on the nodeJS side, i'm using mongoose ODM to handle "joining" the data when needed. This field is essentially a string. it works in both the mongodb extension for railo and mongodb itself, but throws an error "invalid objectID".. Is that something i can work around with some modification?

2. this is the big one for me. I'm taking the cfquery results, iterating, converting to a struct (queryRowToStruct) and then stashing that in mongodb. I'm still getting string for everything. I've tried various javaCast and createObject(...javaDate..).init(mydate).. but its still landing as a string! further investigation indicates similar behavior is happening to ints as well.. Is it the fact that i'm converting to a struct? Also, can i feed a full query into some method in your wrapper?

any help would be great! i'm on the vere of just using epoch time, but i don't think that'll work quite right given the fact that it'd still be a string, mongo might not order it correctly..
