I think you would have to ask the developer this. It is not a Rails issue.
Perhaps in this case the developer allowed the field to be left empty,
marking it as an optional field.

Rails does not have a convention in this any more than php does. It
is not an issue for the underlying framework or language, it is a
matter for the developer.
