def _assign_attribute(k, v)
  # CPK. This is super ugly, but if a table has a composite key where one of the fields is named :id we need
  # to handle it as a single value. Otherwise, we would call the id=(value) method which is expecting
  # and array of values.
  if k == 'id' && !v.kind_of?(Array) && self.kind_of?(ActiveRecord::Base) && self.composite? && !self.column_for_attribute(k).null
