SeedFu::Seeder

Creates or updates seed records with data.

It is not recommended to use this class directly. Instead, use `Model.seed`, and `Model.seed_once`, where `Model` is your Active Record model.

@param [ActiveRecord::Base] model_class The model to be seeded @param [Array<Symbol>] constraints A list of attributes which identify a particular seed. If

a record with these attributes already exists then it will be updated rather than created.

@param [Array<Hash>] data Each item in this array is a hash containing attributes for a

particular record.

@param [Hash] options @option options [Boolean] :quiet (SeedFu.quiet) If true, output will be silenced @option options [Boolean] :insert_only (false) If true then existing records which match the

constraints will not be updated, even if the seed data has changed
