Instance Method Details

#to_symNilClass

expand_hash_conditions_for_aggregates assumes our hash keys can be converted to symbols, so this has to be implemented, but it doesn't really have to do anything useful.

Returns:

  • (NilClass)

    Just to avoid bombing out on expand_hash_conditions_for_aggregates
