Overview

Timestamps

Timestamps can be mixed into your DataModel classes in order to provide with fields to store when records are created and updated.

Example:

require 'mince/data_model'

Class UserDataModel
include Mince::DataModel
include Mince::DataModel::Timestamps

data_collection :users
data_fields :username
end

UserDataModel.add username: 'coffeencoke'
data_model = UserDataModel.find_by_field :username, 'coffeencoke'
data_model.created_at # => todo: returns date time in utc
data_model.updated_at # => todo: returns date time in utc

Whenever a database persisting message is called for a record, the updated_at timestamp will be updated.
