* Deprecate passing a string as third argument of `add_index`Rafael Mendonça França2012-11-021-0/+7
| | | | | | | This was there due historical reasons since 7dc45818dc43c163700efc9896a0f3feafa31138 to give the user the possibility to create unique indexes passing "UNIQUE" as the third argument

* Fix `attributes_before_type_cast` for serialised attributes.Nikita Afanasenko2012-10-311-0/+4
| | | | Public method `attributes_before_type_cast` used to return internal AR structure (ActiveRecord::AttributeMethods::Serialization::Attribute), patch fixes this. Now behaves like `read_attribute_before_type_cast` and returns unserialised values.

| | | | | | | | | | | | | | | | | | | | | | | | This fixes the following behaviour: class Person < ActiveRecord::Base belongs_to :company end # Before: person = Person.select('id').first person[:name] # => nil person.name # => ActiveModel::MissingAttributeError: missing_attribute: name person[:company_id] # => nil person.company # => nil # After: person = Person.select('id').first person[:name] # => ActiveModel::MissingAttributeError: missing_attribute: name person.name # => ActiveModel::MissingAttributeError: missing_attribute: name person[:company_id] # => ActiveModel::MissingAttributeError: missing_attribute: company_id person.company # => ActiveModel::MissingAttributeError: missing_attribute: company_id Fixes #5433.

* Decode attributes pulled from URI.parseShawn Veader2012-10-261-1/+5
| | | | | | | The RFC indicates that username and passwords may be encoded. http://tools.ietf.org/html/rfc2396#section-3.2.2 Found this trying to use the mysql://username:password@host:port/db and having special characters in the password which needed to be URI encoded.
* Remove ActiveRecord::ModelJon Leighton2012-10-261-28/+0
| | | | | | | | | | In the end I think the pain of implementing this seamlessly was not worth the gain provided. The intention was that it would allow plain ruby objects that might not live in your main application to be subclassed and have persistence mixed in. But I've decided that the benefit of doing that is not worth the amount of complexity that the implementation introduced.

* Revert "Get rid of the ActiveRecord::Model::DeprecationProxy thing."Jeremy Kemper2012-10-201-8/+1

* Get rid of the ActiveRecord::Model::DeprecationProxy thing.Jon Leighton2012-10-191-1/+8
| | | | | | | | | | | | | | | | | I think it's going to be too much pain to try to transition the :active_record load hook from executing against Base to executing against Model. For example, after Model is included in Base, and modules included in Model will no longer get added to the ancestors of Base. So plugins which wish to be compatible with both Model and Base should use the :active_record_model load hook which executes *before* Base gets loaded. In general, ActiveRecord::Model is an advanced feature at the moment and probably most people will continue to inherit from ActiveRecord::Base for the time being.
* Rename the partial_updates config to partial_writesJon Leighton2012-10-191-0/+4
| | | | This reflects the fact that it now impact inserts as well as updates.
* nodoc the first_or_create methods and document alternativesJon Leighton2012-10-191-3/+11
|
* Add Relation#find_or_create_by and friendsJon Leighton2012-10-191-2/+32
| | | | | | | This is similar to #first_or_create, but slightly different and a nicer API. See the CHANGELOG/docs in the commit. Fixes #7853
* Fix bug with presence validation of associations.Scott Willson2012-10-161-0/+5
| | | | Would incorrectly add duplicated errors when the association was blank. Bug introduced in 1fab518c6a75dac5773654646eb724a59741bc13.

* Count returns 0 without querying if parent is not savedFrancesco Rodriguez2012-10-031-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | Patches `CollectionAssociation#count` to return 0 without querying if the parent record is new. Consider the following code: class Account has_many :dossiers end class Dossier belongs_to :account end a = Account.new a.dossiers.build # before patch a.dossiers.count # SELECT COUNT(*) FROM "dossiers" WHERE "dossiers"."account_id" IS NULL # => 0 # after a.dosiers.count # fires without sql query # => 0 Fixes #1856.
* Fix reset_counters() crashing on has_many :through associations.lulalala2012-10-021-0/+5

|
* Support for partial inserts.Jon Leighton2012-09-281-0/+13
| | | | | | | | | | | When inserting new records, only the fields which have been changed from the defaults will actually be included in the INSERT statement. The other fields will be populated by the database. This is more efficient, and also means that it will be safe to remove database columns without getting subsequent errors in running app processes (so long as the code in those processes doesn't contain any references to the removed column).

| | | | | | | This reverts commit 761bc751d31c22e2c2fdae2b4cdd435b68b6d783. This commit wasn't fixing any issue just using the same table for different models with different primary keys.
* Support for specifying transaction isolation levelJon Leighton2012-09-211-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If your database supports setting the isolation level for a transaction, you can set it like so: Post.transaction(isolation: :serializable) do # ... end Valid isolation levels are: * `:read_uncommitted` * `:read_committed` * `:repeatable_read` * `:serializable` You should consult the documentation for your database to understand the semantics of these different levels: * http://www.postgresql.org/docs/9.1/static/transaction-iso.html * https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html An `ActiveRecord::TransactionIsolationError` will be raised if: * The adapter does not support setting the isolation level * You are joining an existing open transaction * You are creating a nested (savepoint) transaction The mysql, mysql2 and postgresql adapters support setting the transaction isolation level. However, support is disabled for mysql versions below 5, because they are affected by a bug (http://bugs.mysql.com/bug.php?id=39170) which means the isolation level gets persisted outside the transaction.
