module FieldRequireable
# Returns field names that will be used to validate the presence of
# dynamically created fields from loaded objects.

# You must override this method if you want to return field names that
# are required to be present. You may simply return a static array, but
# if you want to dynamically manipulate this field, return a variable.

# A) The field was defined on the model explicitly (e.g. attr_accessor :field).
# B) The field was created as a result of loading data dynamically.
