Saving in mongoDb with Mongoose, unexpected elements saved - mongodb

Question

When I write in my mongoDB with mongoose the operation is treated with success, my document is saved, but there is also all kind of weird other sutff written down. It seems to be mongoose code. What could cause this?
I add stuff in a specific array with:
resultReference.ref[arrayLocation].allEvents.push(theEvent);
{id: 11, allEvents: [] } is the structure of a ref element, and I push theEvent in the allEvents array. I then resultReference.save()
I use express, mongoose and mongoHQ for database. I tried on a local mongo server, and this annoyance is still there. I've print in my console the document to write before save() and non of this weird code is there.

Answer 1

The reason this happened is because I didnt save my schema in mongoose in the proper order. This would mean declaring your child schema before a parent to get proper behavior.
