upsert(attributes, returning: nil, unique_by: nil) public

Updates or inserts (upserts) a single record into the database in a single SQL INSERT statement. It does not instantiate any models nor does it trigger Active Record callbacks or validations. Though passed values go through Active Record’s type casting and serialization.

See ActiveRecord::Persistence#upsert_all for documentation.
