Importing a MongoDb Collection through Ruby (ROR)

I'm trying to seed my database with a collection exported via the mongoexport tool, but I can't seem to find any way to use the mongoimport tool through Ruby.

I looked at the Mongo Driver for how to execute mongo queries via Ruby, and thought about iterating through each line of json from the export, but there are keys like "$oid" which give errors when attempting to do a collection.insert()

Is it possible to use the mongoimport tool in Ruby, or what's the best way to add code to seeds.rb so that it imports a mongo collection?

mongoexport exports documents in an extended json format specified in the MongoDB docs.

http://www.mongodb.org/display/DOCS/Mongo+Extended+JSON

The driver doesn't read this format automatically. For seeding a database, you may want to use mongodump and mongorestore, which use the database's native BSON format. As another poster mentioned, you could easily shell out to do this.

The mongoimport tool is actually a command-line tool. So you don't use the Mongo Driver for this.

Instead you should "shell out" and call the process. Here's a link on calling a command from the shell.
