What is the nil/zero value of bson.ObjectId

Question

I was creating unary tests when I got stuck on the following situation:

• I have an object that has a foreign key. For some reason, I need to switch the ID and it works. However, sometimes, I need to remove this ID. If I have an ID, I realise a certain action and if I don't, then nothing happens.

However, I can't find the way to set my bson.ObjectId as nil or zero.

Does anyone knows how to do or a work around?

Answer 1

Or you can use the primitive.NilObjectID

NilObjectID is the zero value for ObjectID.

Answer 2

bson.ObjectId is an alias for string , therefore the zero value is an empty string ""
