Basically, don't worry unless you see a deprecation warning + or (in future releases) an SQL error due to a missing JOIN. + + [Jon Leighton] + +* Support for the `schema_info` table has been dropped. Please + switch to `schema_migrations`. + +* Connections *must* be closed at the end of a thread. If not, your + connection pool can fill and an exception will be raised. + +* Added the `ActiveRecord::Model` module which can be included in a + class as an alternative to inheriting from `ActiveRecord::Base`: + + class Post + include ActiveRecord::Model + end + + Please note: + + * Up until now it has been safe to assume that all AR models are + descendants of `ActiveRecord::Base`. This is no longer a safe + assumption, but it may transpire that there are areas of the + code which still make this assumption. So there may be + 'teething difficulties' with this feature. (But please do try it + and report bugs.) + + * Plugins & libraries etc that add methods to `ActiveRecord::Base` + will not be compatible with `ActiveRecord::Model`. Those libraries + should add to `ActiveRecord::Model` instead (which is included in + `Base`), or better still, avoid monkey-patching AR and instead + provide a module that users can include where they need it. + + * To minimise the risk of conflicts with other code, it is + advisable to include `ActiveRecord::Model` early in your class + definition. + + *Jon Leighton* + +* PostgreSQL hstore records can be created. + +* PostgreSQL hstore types are automatically deserialized from the database. + ## Rails 3.2.0 (unreleased) ## +* Added a `with_lock` method to ActiveRecord objects, which starts + a transaction, locks the object (pessimistically) and yields to the block. + The method takes one (optional) parameter and passes it to `lock!`. + + Before: + + class Order < ActiveRecord::Base + def cancel! + transaction do + lock! + # ... cancelling logic + end + end + end + + After: + + class Order < ActiveRecord::Base + def cancel! + with_lock do + # ... cancelling logic + end + end + end + + *Olek Janiszewski* + +* 'on' and 'ON' boolean columns values are type casted to true + *Santiago Pastorino* + +* Added ability to run migrations only for given scope, which allows + to run migrations only from one engine (for example to revert changes + from engine that you want to remove). + + Example: + rake db:migrate SCOPE=blog + + *Piotr Sarnacki* + +* Migrations copied from engines are now scoped with engine's name, + for example 01_create_posts.blog.rb. *Piotr Sarnacki* + +* Implements `AR::Base.silence_auto_explain`. This method allows the user to + selectively disable automatic EXPLAINs within a block. *fxn* + +* Implements automatic EXPLAIN logging for slow queries. + + A new configuration parameter `config.active_record.auto_explain_threshold_in_seconds` + determines what's to be considered a slow query. Setting that to `nil` disables + this feature. Defaults are 0.5 in development mode, and `nil` in test and production + modes. + + As of this writing there's support for SQLite, MySQL (mysql2 adapter), and + PostgreSQL. + + *fxn* + +* Implemented ActiveRecord::Relation#pluck method + + Method returns Array of column value from table under ActiveRecord model + + Client.pluck(:id) + + *Bogdan Gusiev* + +* Automatic closure of connections in threads is deprecated. For example + the following code is deprecated: + + Thread.new { Post.find(1) }.join + + It should be changed to close the database connection at the end of + the thread: + + Thread.new { + Post.find(1) + Post.connection.close + }.join + + Only people who spawn threads in their application code need to worry + about this change. + +* Deprecated: + + * `set_table_name` + * `set_inheritance_column` + * `set_sequence_name` + * `set_primary_key` + * `set_locking_column` + + Use an assignment method instead.

For a class named `MyModel`, the module is named + `MyModel::GeneratedFeatureMethods`.

So if the hierarchy - # looks like: Reply < Message < ActiveRecord::Base, then Message is used - # to guess the table name even when called on Reply. The rules used to do the guess - # are handled by the Inflector class in Active Support, which knows almost all common - # English inflections. You can add new inflections in config/initializers/inflections.rb. - # - # Nested classes are given table names prefixed by the singular form of - # the parent's table name. Enclosing modules are not considered. - # - # ==== Examples - # - # class Invoice < ActiveRecord::Base - # end - # - # file class table_name - # invoice.rb Invoice invoices - # - # class Invoice < ActiveRecord::Base - # class Lineitem < ActiveRecord::Base - # end - # end - # - # file class table_name - # invoice.rb Invoice::Lineitem invoice_lineitems - # - # module Invoice - # class Lineitem < ActiveRecord::Base - # end - # end - # - # file class table_name - # invoice/lineitem.rb Invoice::Lineitem lineitems - # - # Additionally, the class-level +table_name_prefix+ is prepended and the - # +table_name_suffix+ is appended. So if you have "myapp_" as a prefix, - # the table name guess for an Invoice class becomes "myapp_invoices". - # Invoice::Lineitem becomes "myapp_invoice_lineitems". - # - # You can also overwrite this class method to allow for unguessable - # links, such as a Mouse class with a link to a "mice" table.
