  • Next feature description here

3.1

  • Begin migration to Sequel for Query::Sql.
    • #_execute uses it for a database-agnostic adapter for running raw SQL.
    • #_multi_get uses it generate a datbase-agnostic where clause
  • Added accessor generation for one_to_many associations in resources.
  • Imported Model extensions for FactoryGirl to praxis-mapper/support/factory_girl.
  • This also adds IdentityMap#persist! to insert all rows in the identity map into the database.
  • Added SchemaDumper and SchemaLoader for dumping and loading schema information in praxis-mapper/support/schema_dumper and praxis-mapper/support/schema_loader respectively.
  • IdentityMap#all now accepts non-identity keys as conditions, and will create a secondary index for the key the first time it's queried.
  • Added Model#identities to get a hash of identities and values for a record.
  • Auto-generated attribute accessors on Blueprint do not load (coerce) the value using the attribute. Ensure values passed in already have the appropriate types. Blueprint attributes will still be wrapped properly, however.
  • Performance and memory use optimizations.
  • IdentityMap#load now supports eagerly-loading associated records in a query, and supports the full set of options on the inner query, including
  • Tracked :one_to_many associations now support where clauses. Using where clauses when tracking other association types is not supported and will raise an exception.

3.0

  • Moved Blueprint inner attribute creation to finalize!
  • Added :dsl_compiler and :identity as valid options for Blueprint.
  • Praxis::Mapper::Model
    • Model.context allows named query parameters to be reused across queries. See documentation for details.
    • Model#_query references original query that loaded the record.
    • Model.serialized_fields returns hash of fields defined with either json or yaml directives as serialized fields.
    • Fixed accessors will to raise KeyError if the record does not the field (i.e., if it was not loaded from the database), rather than silently returning nil.
  • Praxis::Mapper::Query:
    • Multiple select and track calls within one query are now additive.
    • track option now takes a block that will be applied to the query used to load the tracked records.
    • context directive to apply the named context from the model to the query. See documentation for more.
  • Praxis::Mapper::IdentityMap
    • Removed :track option from #add_records in favor of using Model#_query to determine tracked associations.
  • Added Praxis::Mapper::Support with MemoryQuery and MemoryRepository for use in testing data loading without requiring a database.

Notices

The Model accessor changes may break existing applications that (incorrectly) expect unloaded attributes to return nil.
