Raw

v0.5.0 2014-12-31

Added

  • Mapper DSL supports embedded interface for nested tuples (solnic)
  • Support for nested group mapping (solnic)
  • Support for nested wrap mapping (solnic)
  • Support for primitive type coercions (:to_string, :to_integer etc.) (solnic)
  • Support for top-level :prefix option in mapping DSL (solnic)
  • Support for top-level :symbolize_keys option in mapping DSL (solnic)
  • Support for :prefix option in wrap/group mapping DSL (solnic)
  • Interface for registering data mapping processors (solnic)
  • Remaining relations are automatically setup from the schema (solnic)
  • Each relation has now access to other relations (previously they only had access to raw datasets) (solnic)
  • ROM.setup supports passing in just an uri which will setup a default repository (solnic)
  • ROM.setup supports passing in conventional database connection hash (solnic)
  • Adapters support extra options in addition to the base connection URI (solnic)

Changed

  • Mapping backend replaced by integration with transproc (solnic)
  • Readers no longer expose adapter query DSL (solnic)
  • Registry objects raise ROM::Registry::ElementNotFoundError when missing element is referenced (rather than raw KeyError) (solnic)
  • Performance improvements in Reader (solnic)
  • ROM::RA was merged into in-memory adapter as this fits there perfectly (solnic)
  • It is no longer needed to explicitly execute a delete command in try block (solnic)

Fixed

  • Wrap/group skips empty tuples now (solnic)
  • Readers raise a meaningful error when relation is missing (solnic)

Internal

  • Massive code clean-up and rubocop integration (chastell)
  • Refactored Reader and mapper-specific logic into MapperRegistry (solnic)

Compare v0.4.2...v0.5.0

v0.4.2 2014-12-19

  • Mappers support tuple transformation using wrap and group operations (solnic)
  • PORO model builder supports namespaced constants via name: 'MyApp:Entities::User (solnic)

Changed

  • ROM::RA interface is no longer mixed into relations by default (solnic)
  • ~2.5 x speed up in aggregate mapping (solnic)
  • PORO model builder only defines attribute readers now (no writers!) (solnic)
  • Registry objects in Env will now raise KeyError when unknown name is referenced (solnic)

Compare v0.4.1...v0.4.2

v0.4.1 2014-12-15

Added

  • Adapter can now implement Adapter#dataset(name, header) to return a dataset (solnic)
  • For multi-step setup the DSL is available in ROM too (solnic)
  • Global environment can be stored via ROM.finalize and accessible via ROM.env (solnic)
  • Mapper won't infer attributes from the header if :inherit_header option is set to false (solnic)

Changed

  • Schema can be defined in multiple steps (solnic)
  • Setting model in mapper DSL is no longer required and defaults to Hash (solnic)

  • New Adapter#dataset?(name) which every adapter must implement (solnic)

Fixed

  • method-missing in Repository and Env kindly calls super (solnic)
