Can't convert to JSON

[aigarsdz]

After calling #to_json on a query result, i get an error:

no overload matches 'BSON::ObjectId#to_json' with type JSON::Builder

Am I doing something wrong or is this functionality not supported?

Thanks for catching this. That part of the code was untested and carried over from a very old version of granite orm. Now you should be able to call .to_json on any mongo_orm object. That said, do know that Mongo uses something called BSON, which is slightly different, and calling .to_bson will already give you a BSON object, and .to_bson.to_s is very similar to JSON. The .to_json method I wrote will give you crystal-formatted datetime values, while the .to_bson method will give you things in Mongo's internal formats.

That's good to know, thank you!
