Mongo/BSON: no decoder found for orb.Geometry about orb HOT 6 CLOSED

I have PR to add support for BSON. Please have a look #123

from orb.

Weird that it works for insert but not find.

I would guess the FeatureCollection type needs to implement MarshalBSON and UnmarshalBSON. I'm surprised the driver doesn't fallback to MarshalJSON is those aren't available.

Yeah it's really weird... It does fallback to MarshalJSON. But if I wrap MarshalJSON in a function like follows

func (fc FeatureCollection) MarshalBSON() ([]byte, error) {
	return fc.MarshalJSON()
}

I get runtime error: invalid memory address or nil pointer dereference

And if I implement UnmarshalBSON like follows:

func (fc FeatureCollection) UnmarshalBSON(data []byte) error {
	return fc.UnmarshalJSON(data)
}

I get error decoding key routes.0.legs: invalid character 'î' looking for beginning of value

This is my first bigger project in Go, so I'm not entirely sure how I should go about this, but I can't imagine I'm the first who tries to insert a geoJSON in a mongoDB using Go? 😄 Any chance you can point me in the right direction?

Find decodes the data to Go values. Decode fails because the codec does not know the type to create for an orb.Geometry.

Yes.

BSON and JSON are different data encodings. MarshalJSON returns JSON, not BSON.

Thanks @paulmach, I'll check it on friday!
