068f092cedregistered autosave callbacks as `after_save` callbacks. This caused the regression described in #17209. Autosave callbacks should be registered as `after_update` and `after_create` callbacks, just like before. This is a partial revert of068f092ced. Fixes #17209.

* Fix regression causing `after_create` callbacks to run before associated
|
|
records are autosaved.

|
* Add a truncate method to the connection.

*Yves Senn*
|
|

* PostgreSQL adapter correctly dumps foreign keys targeting tables
|
|
outside the schema search path.
|
|
|
|
Fixes #16907.

|
|
*Matthew Draper*, *Yves Senn*
|
|
|
|
* When a thread is killed, rollback the active transaction, instead of
|
|
committing it during the stack unwind. Previously, we could commit half-
|
|
completed work. This fix only works for Ruby 2.0+; on 1.9, we can't
|
|
distinguish a thread kill from an ordinary non-local (block) return, so must
|
|
default to committing.
|
|
|
|
*Chris Hanks*
|
|
|
|
* A `NullRelation` should represent nothing. This fixes a bug where
|
|
`Comment.where(post_id: Post.none)` returned a non-empty result.
|
|
|
|
Fixes #15176.
|
|
|
|
*Matthew Draper*, *Yves Senn*
|
|
|
|
* Include default column limits in schema.rb. Allows defaults to be changed
|
|
in the future without affecting old migrations that assumed old defaults.
|
|
|
|
*Jeremy Kemper*
|
|
|
|
* MySQL: schema.rb now includes TEXT and BLOB column limits.
|

|
* SQLite3Adapter now checks for views in `table_exists?`. Fixes #14041.
|
|
|
|
*Girish Sonawane*
|
|
|
|
* Introduce `connection.supports_views?` to check whether the current adapter
|
|
has support for SQL views. Connection adapters should define this method.
|
|
|
|
*Yves Senn*
|
|
|

|
|
|
|
* Schema loading rake tasks (like `db:schema:load` and `db:setup`) maintain
|
|
the database connection to the current environment.
|
|
|
|
Fixes #16757.
|
|
|
|
*Joshua Cody*, *Yves Senn*
|
|
|
|
* MySQL: set the connection collation along with the charset.
|
|
|
|
Sets the connection collation to the database collation configured in
|
|
database.yml. Otherwise, `SET NAMES utf8mb4` will use the default
|
|
collation for that charset (utf8mb4_general_ci) when you may have chosen
|
|
a different collation, like utf8mb4_unicode_ci.
|
|
|
|
This only applies to literal string comparisons, not column values, so it
|
|
is unlikely to affect you.
|
|
|
|
*Jeremy Kemper*
|
|
|
|
* `default_sequence_name` from the PostgreSQL adapter returns a `String`.
|
|
|
|
*Yves Senn*
|
|
|
|
* Fixed a regression where whitespaces were stripped from DISTINCT queries in
|
|
PostgreSQL.
|

*Agis Anastasopoulos*
|
|
|
|
Fixes #16623.
|
|
|
|
* Fix has_many :through relation merging failing when dynamic conditions are
|
|
passed as a lambda with an arity of one.
|
|
|
|
Fixes #16128.
|
|
|
|
*Agis Anastasopoulos*
|
|
|
|
* Fixed `Relation#exists?` to work with polymorphic associations.
|
|
|
|
Fixes #15821.
|
|
|
|
*Kassio Borges*
|
|
|
|
* Currently, Active Record rescues any errors raised within
|
|
`after_rollback`/`after_create` callbacks and prints them to the logs.
|
|
Future versions of Rails will not rescue these errors anymore and
|
|
just bubble them up like the other callbacks.
|
|
|
|
This commit adds an opt-in flag to enable not rescuing the errors.
|
|
|
|
Example:
|
|
|
|
# Do not swallow errors in after_commit/after_rollback callbacks.
|
|
config.active_record.raise_in_transactional_callbacks = true
|
|
|
|
Fixes #13460.
|
|
|
|
*arthurnn*
|
|
|
|
* Fixed an issue where custom accessor methods (such as those generated by
|
|
`enum`) with the same name as a global method are incorrectly overridden
|
|
when subclassing.
|
|
|
|
Fixes #16288.
|
|
|
|
*Godfrey Chan*
|
|
|
|
* `*_was` and `changes` now work correctly for in-place attribute changes as
|
|
well.
|
|
|
|
*Sean Griffin*
|
|
|
|
* Fix regression on `after_commit` that did not fire with nested transactions.
|
|
|
|
Fixes #16425.
|
|
|
|
*arthurnn*
|
|
|
|
* Do not try to write timestamps when a table has no timestamps columns.
|
|
|
|
Fixes #8813.
|
|
|
|
*Sergey Potapov*
|
|
|
|
* `index_exists?` with `:name` option does verify specified columns.
|
|
|
|
Example:
|
|
|
|
add_index :articles, :title, name: "idx_title"
|
|
|
|
# Before:
|
|
index_exists? :articles, :title, name: "idx_title" # => `true`
|
|
index_exists? :articles, :body, name: "idx_title" # => `true`
|
|
|
|
# After:
|
|
index_exists? :articles, :title, name: "idx_title" # => `true`
|
|
index_exists? :articles, :body, name: "idx_title" # => `false`
|
|
|
|
*Yves Senn*, *Matthew Draper*
|
|
|
|
* When calling `update_columns` on a record that is not persisted, the error
|
|
message now reflects whether that object is a new record or has been
|
|
destroyed.
|
|
|
|
*Lachlan Sylvester*
|
|
|
|
* Define `id_was` to get the previous value of the primary key.
|
|
|
|
Currently when we call `id_was` and we have a custom primary key name,
|
|
Active Record will return the current value of the primary key. This
|
|
makes it impossible to correctly do an update operation if you change the
|
|
id.
|
|
|
|
Fixes #16413.
|
|
|
|
*Rafael Mendonça França*
|
|
|
|
* Deprecate `DatabaseTasks.load_schema` to act on the current connection.
|
|
Use `.load_schema_current` instead. In the future `load_schema` will
|
|
require the `configuration` to act on as an argument.
|
|
|
|
*Yves Senn*
|
|
|
|
* Fixed automatic maintaining test schema to properly handle sql structure
|
|
schema format.
|
|
|
|
Fixes #15394.
|
|
|
|
*Wojciech Wnętrzak*
|
|
|
|
* Fix type casting to Decimal from Float with large precision.
|
|
|
|
*Tomohiro Hashidate*
|
|
|
|
* Deprecate `Reflection#source_macro`
|
|
|
|
`Reflection#source_macro` is no longer needed in Active Record
|
|
source so it has been deprecated. Code that used `source_macro`
|
|
was removed in #16353.
|
|
|
|
*Eileen M. Uchtitelle*, *Aaron Patterson*
|
|
|
|
* No verbose backtrace by `db:drop` when database does not exist.
|
|
|
|
Fixes #16295.
|
|
|
|
*Kenn Ejima*
|
|
|
|
* Add support for PostgreSQL JSONB.
|
|
|
|
Example:
|
|
|
|
create_table :posts do |t|
|
|
t.jsonb :meta_data
|
|
end
|
|
|
|
*Philippe Creux*, *Chris Teague*
|
|
|
|
* `db:purge` with MySQL respects `Rails.env`.
|
|
|
|
*Yves Senn*
|
|
|
|
* `change_column_default :table, :column, nil` with PostgreSQL will issue a
|
|
`DROP DEFAULT` instead of a `DEFAULT NULL` query.
|
|
|
|
Fixes #16261.
|
|
|
|
*Matthew Draper*, *Yves Senn*
|
|
|
|
* Allow to specify a type for the foreign key column in `references`
|
|
and `add_reference`.
|
|
|
|
Example:
|
|
|
|
change_table :vehicle do |t|
|
|
t.references :station, type: :uuid
|
|
end
|
|
|
|
*Andrey Novikov*, *Łukasz Sarnacki*
|
|
|
|
* `create_join_table` removes a common prefix when generating the join table.
|
|
This matches the existing behavior of HABTM associations.
|
|
|
|
Fixes #13683.
|
|
|
|
*Stefan Kanev*
|
|
|
|
* Do not swallow errors on `compute_type` when having a bad `alias_method` on
|
|
a class.
|
|
|
|
*arthurnn*
|
|
|
|
* PostgreSQL invalid `uuid` are convert to nil.
|
|
|
|
*Abdelkader Boudih*
|
|
|
|
* Restore 4.0 behavior for using serialize attributes with `JSON` as coder.
|
|
|
|
With 4.1.x, `serialize` started returning a string when `JSON` was passed as
|
|
the second attribute. It will now return a hash as per previous versions.
|
|
|
|
Example:
|
|
|
|
class Post < ActiveRecord::Base
|
|
serialize :comment, JSON
|
|
end
|
|
|
|
class Comment
|
|
include ActiveModel::Model
|
|
attr_accessor :category, :text
|
|
end
|
|
|
|
post = Post.create!
|
|
post.comment = Comment.new(category: "Animals", text: "This is a comment about squirrels.")
|
|
post.save!
|
|
|
|
# 4.0
|
|
post.comment # => {"category"=>"Animals", "text"=>"This is a comment about squirrels."}
|
|
|
|
# 4.1 before
|
|
post.comment # => "#<Comment:0x007f80ab48ff98>"
|
|
|
|
# 4.1 after
|
|
post.comment # => {"category"=>"Animals", "text"=>"This is a comment about squirrels."}
|
|
|
|
When using `JSON` as the coder in `serialize`, Active Record will use the
|
|
new `ActiveRecord::Coders::JSON` coder which delegates its `dump/load` to
|
|
`ActiveSupport::JSON.encode/decode`. This ensures special objects are dumped
|
|
correctly using the `#as_json` hook.
|
|
|
|
To keep the previous behaviour, supply a custom coder instead
|
|
([example](https://gist.github.com/jenncoop/8c4142bbe59da77daa63)).
|
|
|
|
Fixes #15594.

* Do not use `RENAME INDEX` syntax for MariaDB 10.0.
|
|
|

Fixes #15931.

|
*Jeff Browning*
|
|
|
|
* Calling `#empty?` on a `has_many` association would use the value from the
|
|
counter cache if one exists.
|
|
|
|
*David Verhasselt*
|
|
|
|
* Fix the schema dump generated for tables without constraints and with
|
|
primary key with default value of custom PostgreSQL function result.
|
|
|
|
Fixes #16111.
|
|
|
|
*Andrey Novikov*
|
|
|
|
* Fix the SQL generated when a `delete_all` is run on an association to not
|
|
produce an `IN` statements.
|
|
|
|
Before:
|
|
|
|
UPDATE "categorizations" SET "category_id" = NULL WHERE
|
|
"categorizations"."category_id" = 1 AND "categorizations"."id" IN (1, 2)
|
|
|
|
After:
|
|
|
|
UPDATE "categorizations" SET "category_id" = NULL WHERE
|
|
"categorizations"."category_id" = 1
|
|
|
|
*Eileen M. Uchitelle, Aaron Patterson*
|
|
|
|
* Avoid type casting boolean and `ActiveSupport::Duration` values to numeric
|
|
values for string columns. Otherwise, in some database, the string column
|
|
values will be coerced to a numeric allowing false or 0.seconds match any
|
|
string starting with a non-digit.
|
|
|
|
Example:
|
|
|
|
App.where(apikey: false) # => SELECT * FROM users WHERE apikey = '0'
|
|
|
|
*Dylan Thacker-Smith*
|
|
|
|
* Add a `:required` option to singular associations, providing a nicer
|
|
API for presence validations on associations.
|
|
|
|
*Sean Griffin*
|
|
|
|
* Fixed error in `reset_counters` when associations have `select` scope.
|
|
(Call to `count` generates invalid SQL.)
|
|
|
|
*Cade Truitt*
|
|
|
|
* After a successful `reload`, `new_record?` is always false.
|
|
|
|
Fixes #12101.
|
|
|
|
*Matthew Draper*
|
|
|
|
* PostgreSQL renaming table doesn't attempt to rename non existent sequences.
|
|
|
|
*Abdelkader Boudih*
|
|
|
|
* Move 'dependent: :destroy' handling for `belongs_to`
|
|
from `before_destroy` to `after_destroy` callback chain
|
|
|
|
Fixes #12380.
|
|
|
|
*Ivan Antropov*
|
|
|
|
* Detect in-place modifications on String attributes.
|
|
|
|
Before this change, an attribute modified in-place had to be marked as
|
|
changed in order for it to be persisted in the database. Now it is no longer
|
|
required.
|
|
|
|
Before:
|
|
|
|
user = User.first
|
|
user.name << ' Griffin'
|
|
user.name_will_change!
|
|
user.save
|
|
user.reload.name # => "Sean Griffin"
|
|
|
|
After:
|
|
|
|
user = User.first
|
|
user.name << ' Griffin'
|
|
user.save
|
|
user.reload.name # => "Sean Griffin"
|
|
|
|
*Sean Griffin*
|
|
|
|
* Add `ActiveRecord::Base#validate!` that raises `RecordInvalid` if the record
|
|
is invalid.
|
|
|
|
*Bogdan Gusiev*, *Marc Schütz*
|
|
|
|
* Support for adding and removing foreign keys. Foreign keys are now
|
|
a part of `schema.rb`. This is supported by Mysql2Adapter, MysqlAdapter
|
|
and PostgreSQLAdapter.
|
|
|
|
Many thanks to *Matthew Higgins* for laying the foundation with his work on
|
|
[foreigner](https://github.com/matthuhiggins/foreigner).
|
|

# within your migrations:
|
|
add_foreign_key :articles, :authors
|
|
remove_foreign_key :articles, :authors

* Fix subtle bugs regarding attribute assignment on models with no primary
|
|
key. `'id'` will no longer be part of the attributes hash.
|
|
|
|
*Sean Griffin*
|
|
|
|
* Deprecate automatic counter caches on `has_many :through`. The behavior was

|
|
|
|
* Assume numeric types have changed if they were assigned to a value that
|
|
would fail numericality validation, regardless of the old value. Previously
|
|
this would only occur if the old value was 0.
|
|
|
|
Example:
|
|
|
|
model = Model.create!(number: 5)
|
|
model.number = '5wibble'
|
|
model.number_changed? # => true
|
|

|
*Sean Griffin*
|
|
|
|
* `reload` no longer merges with the existing attributes.
|

The attribute hash is fully replaced. The record is put into the same state
|

as it would be with `Model.find(model.id)`.
|
|
|
|
*Sean Griffin*
|
|
|
|
* The object returned from `select_all` must respond to `column_types`.

|
|
Fixing regression case, where redefining the same `has_and_belongs_to_many`
|

definition into a subclass would raise.
|
|

|
|
* Fix `has_and_belongs_to_many` public reflection.
|
|
When defining a `has_and_belongs_to_many`, internally we convert that to two has_many.
|
|
But as `reflections` is a public API, people expect to see the right macro.
|
|
|
|
Fixes #14682.

|
|
* Change belongs_to touch to be consistent with timestamp updates
|
|
|
|
If a model is set up with a belongs_to: touch relationship the parent
|
|
record will only be touched if the record was modified. This makes it
|
|
consistent with timestamp updating on the record itself.
|
|

* Fixed the inferred table name of a `has_and_belongs_to_many` auxiliar

Fixes #14824.
|
|
|

*Eric Chahin*
|

`ActiveRecord`, such as for XML Serialization.
|
|
|

* Fix bug that added `table_name_prefix` and `table_name_suffix` to
|
|
extension names in PostgreSQL when migrating.
|

|
|
*Joao Carlos*
|
|
|
|

|
* Restrict deletion of record when using `delete_all` with `uniq`, `group`, `having`
|

In these cases the generated query ignored them and that caused unintended
|

records to be deleted.

*Kassio Borges*
|
|
|
|
* `ActiveRecord::Relation::Merger#filter_binds` now compares equivalent symbols and

strings in column names as equal.
|
|
|
|
This fixes a rare case in which more bind values are passed than there are
|

placeholders for them in the generated SQL statement, which can make PostgreSQL

|
throw a `StatementInvalid` exception.

|
|
* Handle `name` and `"char"` column types in the PostgreSQL adapter.
|
|
|
|
`name` and `"char"` are special character types used internally by
|
|
PostgreSQL and are used by internal system catalogs. These field types
|
|
can sometimes show up in structure-sniffing queries that feature internal system
|
|
structures or with certain PostgreSQL extensions.

*J Smith*, *Yves Senn*
|
|
|
|
* Fix `PostgreSQLAdapter::OID::Float#type_cast` to convert Infinity and
|

NaN PostgreSQL values into a native Ruby `Float::INFINITY` and `Float::NAN`
|
|
|
|
Before:
|
|
|
|
Point.create(value: 1.0/0)

*Patrick Robertson*
|
|
|
|
* Deprecate joining, eager loading and preloading of instance dependent

are created. The current behavior is unexpected and can result in broken
|
|
behavior.
|
|
|
|
Fixes #15024.
|

*Yves Senn*
|
|
|
|
* Fixed has_and_belongs_to_many's CollectionAssociation size calculation.
|
|
|
|
`has_and_belongs_to_many` should fall back to using the normal CollectionAssociation's
|
|
size calculation if the collection is not cached or loaded.

*Paul B.*
|
|
|
|
* Add support for module-level `table_name_suffix` in models.
|
|
|

This makes `table_name_suffix` work the same way as `table_name_prefix` when
|
|
using namespaced models.
|
|
|
|
*Jenner LaFave*
|
|
|
|
* Revert the behaviour of `ActiveRecord::Relation#join` changed through 4.0 => 4.1 to 4.0.
|
|
|
|
In 4.1.0 `Relation#join` is delegated to `Arel#SelectManager`.
|
|
In 4.0 series it is delegated to `Array#join`.

*Bogdan Gusiev*
|
|
|
|
* Log nil binary column values correctly.
|
|
|
|
When an object with a binary column is updated with a nil value
|
|
in that column, the SQL logger would throw an exception when trying
|
|
to log that nil value. This only occurs when updating a record
|
|
that already has a non-nil value in that column since an initial nil
|
|
value isn't included in the SQL anyway (at least, when dirty checking
|
|
is enabled.) The column's new value will now be logged as `<NULL binary data>`
|
|
to parallel the existing `<N bytes of binary data>` for non-nil values.

*Hector Satre*
|
|
|
|
* When using a custom `join_table` name on a `habtm`, rails was not saving it

|
|
Additionally display a warning message to make the user aware.

*Yves Senn*
|
|
|
|
* PostgreSQL should internally use `:datetime` consistently for TimeStamp. Assures
|
|
different spellings of timestamps are treated the same.
|
|
|
|
Example:
|
|
|
|
mytimestamp.simplified_type('timestamp without time zone')
|
|
# => :datetime
|
|
mytimestamp.simplified_type('timestamp(6) without time zone')

|
|
|

* Fixed unexpected behavior for `has_many :through` associations going through a scoped `has_many`.
|
|
|

If a `has_many` association is adjusted using a scope, and another `has_many :through`

uses this association, then the scope adjustment is unexpectedly neglected.

|
|
# => true
|
|
Post.where(author_id: author.id) == author.posts

|
|
* `to_sql` on an association now matches the query that is actually executed, where it
|
|
could previously have incorrectly accrued additional conditions (e.g. as a result of
|
|
a previous query). `CollectionProxy` now always defers to the association scope's

`arel` method so the (incorrect) inherited one should be entirely concealed.

*Henrik Nyh*
|
|
|
|
* Create indexes inline in CREATE TABLE for MySQL.
|
|
|
|
This is important, because adding an index on a temporary table after it has been created
|
|
would commit the transaction.
|
|
|
|
It also allows creating and dropping indexed tables with fewer queries and fewer permissions
|
|
required.
|
|
|
|
Example:
|
|
|
|
create_table :temp, temporary: true, as: "SELECT id, name, zip FROM a_really_complicated_query" do |t|
|
|
t.index :zip
|

* Deprecate half-baked support for PostgreSQL range values with excluding beginnings.
|
|
We currently map PostgreSQL ranges to Ruby ranges. This conversion is not fully
|
|
possible because the Ruby range does not support excluded beginnings.
|
|
|
|
The current solution of incrementing the beginning is not correct and is now
|
|
deprecated. For subtypes where we don't know how to increment (e.g. `#succ`
|
|
is not defined) it will raise an `ArgumentException` for ranges with excluding
|
|
beginnings.
