Node js Mongoose js string to ObjectId function

Question

Is there a function to turn a string into an objectId in node using mongoose  The schema specifies that something is an ObjectId  but when it is saved from a string  mongo tells me it is still just a string  The  id of the object  for instance  is displayed as objectId  blah

I couldn t resolve this method  admittedly I didn t search for long   mongoose mongo BSONPure ObjectID fromHexString   If your schema expects the property to be of type ObjectId  the conversion is implicit  at least this seems to be the case in 4 7 8   You could use something like this however  which gives a bit more flex   function toObjectId ids         if  ids constructor     Array            return ids map mongoose Types ObjectId              return mongoose Types ObjectId ids
