= Active Record -- Object-relational mapping put on rails

Active Record connects classes to relational database tables to establish an
almost zero-configuration persistence layer for applications. The library
provides a base class that, when subclassed, sets up a mapping between the new
class and an existing table in the database. In context of an application,
these classes are commonly referred to as *models*. Models can also be
connected to other models; this is done by defining *associations*.

Log message:
Import ruby-activerecord-4.2.8 as databases/ruby-activerecord42

Notable changes since 3.2:

- Improve ways to write change migrations, making the old up & down
  methods no longer necessary.
- Adds PostgreSQL array type support. Any datatype can be used to
  create an array column, with full migration and schema dumper
  support.
- Add Relation#load to explicitly load the record and return self.
- Model.all now returns an ActiveRecord::Relation, rather than an
  array of records. Use Relation#to_a if you really want an array. In
  some specific cases, this may cause breakage when upgrading.
- Added ActiveRecord::Migration.check_pending! that raises an error if
  migrations are pending.
- Added custom coders support for ActiveRecord::Store.
- mysql and mysql2 connections will set SQL_MODE=STRICT_ALL_TABLES by
  default to avoid silent data loss. This can be disabled by
  specifying strict: false in your database.yml.
- Remove IdentityMap.
- Remove automatic execution of EXPLAIN queries. The option
  active_record.auto_explain_threshold_in_seconds is no longer used
  and should be removed.
- Adds ActiveRecord::NullRelation and ActiveRecord::Relation#none
  implementing the null object pattern for the Relation class.
- Added create_join_table migration helper to create HABTM join
  tables.
- Allows PostgreSQL hstore records to be created.
- Default scopes are no longer overridden by chained conditions.
- Added ActiveRecord::Base.to_param for convenient "pretty" URLs
  derived from a model's attribute or method.
- Added ActiveRecord::Base.no_touching, which allows ignoring touch on
  models.
- Unify boolean type casting for MysqlAdapter and
  Mysql2Adapter. type_cast will return 1 for true and 0 for false.
- .unscope now removes conditions specified in default_scope.
- Added ActiveRecord::QueryMethods#rewhere which will overwrite an
  existing, named where condition.
- Extended ActiveRecord::Base#cache_key to take an optional list of
  timestamp attributes of which the highest will be used.
- Added ActiveRecord::Base#enum for declaring enum attributes where
  the values map to integers in the database, but can be queried by
  name.
- Type cast json values on write, so that the value is consistent with
  reading from the database.
- Type cast hstore values on write, so that the value is consistent
  with reading from the database.
- Make next_migration_number accessible for third party generators.
- Calling update_attributes will now throw an ArgumentError whenever
  it gets a nil argument. More specifically, it will throw an error if
  the argument that it gets passed does not respond to to
  stringify_keys.
- CollectionAssociation#first/#last (e.g. has_many) use a LIMITed
  query to fetch results rather than loading the entire collection.
- inspect on Active Record model classes does not initiate a new
  connection. This means that calling inspect, when the database is
  missing, will no longer raise an exception.
- Removed column restrictions for count, let the database raise if the
  SQL is invalid.
- Rails now automatically detects inverse associations. If you do not
  set the :inverse_of option on the association, then Active Record
  will guess the inverse association based on heuristics.
- Handle aliased attributes in ActiveRecord::Relation. When using
  symbol keys, ActiveRecord will now translate aliased attribute names
  to the actual column name used in the database.
- The ERB in fixture files is no longer evaluated in the context of
  the main object. Helper methods used by multiple fixtures should be
  defined on modules included in
  ActiveRecord::FixtureSet.context_class.
- Don't create or drop the test database if RAILS_ENV is specified
  explicitly.
- Relation no longer has mutator methods like #map! and
  #delete_if. Convert to an Array by calling #to_a before using these
  methods.
- find_in_batches, find_each, Result#each and Enumerable#index_by now
  return an Enumerator that can calculate its size.
- scope, enum and Associations now raise on "dangerous" name
  conflicts.
- second through fifth methods act like the first finder.
- Make touch fire the after_commit and after_rollback callbacks.
- Enable partial indexes for sqlite >= 3.8.0.
- Make change_column_null revertible.
- Added a flag to disable schema dump after migration. This is set to
  false by default in the production environment for new applications.
- SchemaDumper uses force: :cascade on create_table. This makes it
  possible to reload a schema when foreign keys are in place.
- Added a :required option to singular associations, which defines a
  presence validation on the association.
- ActiveRecord::Dirty now detects in-place changes to mutable
  values. Serialized attributes on Active Record models are no longer
  saved when unchanged. This also works with other types such as
  string columns and json columns on PostgreSQL.
- Introduced the db:purge Rake task to empty the database for the
  current environment.
- Introduced ActiveRecord::Base#validate! that raises
  ActiveRecord::RecordInvalid if the record is invalid.
- Introduced validate as an alias for valid?.
- touch now accepts multiple attributes to be touched at once.
- The PostgreSQL adapter now supports the jsonb datatype in PostgreSQL
  9.4+.
- The PostgreSQL and SQLite adapters no longer add a default limit of
  255 characters on string columns.
- Added support for the citext column type in the PostgreSQL adapter.
- Added support for user-created range types in the PostgreSQL
  adapter.
- sqlite3:///some/path now resolves to the absolute system path
  /some/path. For relative paths, use sqlite3:some/path
  instead. (Previously, sqlite3:///some/path resolved to the relative
  path some/path. This behavior was deprecated on Rails 4.1).
- Added support for fractional seconds for MySQL 5.6 and above.
- Added ActiveRecord::Base#pretty_print to pretty print models.
- ActiveRecord::Base#reload now behaves the same as m =
  Model.find(m.id), meaning that it no longer retains the extra
  attributes from custom SELECTs.
- ActiveRecord::Base#reflections now returns a hash with string keys
  instead of symbol keys.
- The references method in migrations now supports a type option for
  specifying the type of the foreign key (e.g. :uuid).
