Question: empty fields

[endymion00]

Hi,
Is it possible to include the empty fields of a model?
Example:
If this data is stored on a dynamo table:

email: "email@example.com"
name: "a name"
phone: null

And the vogels finds this data.
I'd like to know if vogels can return this:

{
email: "email@example.com",
name: "a name",
phone: null
}

instead of:

{
email: "email@example.com",
name: "a name"
}

(note that phone field does not appear. And when trying to get model.get('phone') an 'undefined' is obtained)

Thank you in advance.
