That's not the ObjectId it's complaining about. You have a second one
on Commentaries. Either initialize it, or use `bson:",omitempty"` in
the tag so that it's not sent.

how about  if ObjectId.valid() return false mgo just ignore it  except _id field ,I think this should be default behavior

You mean accepting corrupted ObjectId values as if they were empty?
That doesn't sound like a good idea.

it clearly says (Got 0) so how come it is corrupted its just empty i have very same situation 

type User struct {
   Id             bson.ObjectId `json:"_id,omitempty"bson:"_id,omitempty"`
   Name           string `json:"name"bson:"name,omitempty"`
   Surname        string `json:"surname"bson:"surname,omitempty"`
   ProfilePicture string    `json:"profile_picture"bson:"profile_picture"`
   Username       string `json:"username,omitempty"bson:"username,omitempty"`
   Email          string `json:"email"bson:"email"`
   Password       string `json:"-"bson:"password,omitempty"`

}

And when i create a `new(User)` and try to edit something and then insert i get the same error though i never touched the objectid and i set it to omitempty
