Class Method Details

.deep_merge!(source_hash, new_hash) ⇒ Object

Utility method used in our solr search logic. Merges new_hash into source_hash, but will recursively merge nested arrays and hashes too; also will NOT merge nil or blank values from new_hash into source_hash, nil or blank values in new_hash will not overwrite values in source_hash.
