NULLS NOT DISTINCT works with UNIQUE CONSTRAINT as well as UNIQUE INDEX.

The
db:prepare
task no longer loads seeds when a non-primary database is created.Previously, the
db:prepare
task would load seeds whenever a new database is created, leading to potential loss of data if a database is added to an existing environment.Introduces a new database config property
seeds
to control whether seeds are loaded duringdb:prepare
which defaults totrue
for primary database configs andfalse
otherwise.Fixes #53348.

Fix an issue where
.left_outer_joins
used with multiple associations that have the same child association but different parents does not join all parents.Previously, using
.left_outer_joins
with the same child association would only join one of the parents.Now it will correctly join both parents.
Fixes #41498.

Deprecate
unsigned_float

short-hand column methods.As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL. Consider using a simple CHECK constraint instead for such columns.

Drop MySQL 5.5 support.
MySQL 5.5 is the only version that does not support datetime with precision, which we have supported in the core. Now we support MySQL 5.6.4 or later, which is the first version to support datetime with precision.

Make Active Record asynchronous queries compatible with transactional fixtures.
Previously transactional fixtures would disable asynchronous queries, because transactional fixtures impose all queries use the same connection.
Now asynchronous queries will use the connection pinned by transactional fixtures, and behave much closer to production.

Deserialize binary data before decrypting
This ensures that we call
PG::Connection.unescape_bytea
on PostgreSQL before decryption.Donal McBreen
Ensure ActiveRecord::Encryption.config is always ready before access.
Previously,
::ActiveRecord::Encryption
configuration was deferred until::ActiveRecord::Base
was loaded. Therefore, accessing ActiveRecord::Encryption.config properties before::ActiveRecord::Base
was loaded would give incorrect results.::ActiveRecord::Encryption
now has its own loading hook so that its configuration is set as soon as needed.When
::ActiveRecord::Base
is loaded, even lazily, it in turn triggers the loading of::ActiveRecord::Encryption
, thus preserving the original behavior of having its config ready before any use of::ActiveRecord::Base
.Maxime Réty

Add support for
::ActiveRecord::Point
type casts usingHash
valuesThis allows
::ActiveRecord::Point
to be cast or serialized from a hash with:x
and:y
keys of numeric values, mirroring the functionality of existing casts for string and array values. Both string and symbol keys are supported.class PostgresqlPoint < ActiveRecord::Base attribute :x, :point attribute :y, :point attribute :z, :point end val = PostgresqlPoint.new({ x: '(12.34, -43.21)', y: [12.34, '-43.21'], z: {x: '12.34', y: -43.21} }) ActiveRecord::Point.new(12.32, -43.21) == val.x == val.y == val.z

Include schema name in
enable_extension
statements indb/schema.rb
.The schema dumper will now include the schema name in generated
enable_extension
statements if they differ from the current schema.For example, if you have a migration:
enable_extension "heroku_ext.pgcrypto" enable_extension "pg_stat_statements"
then the generated schema dump will also contain:
enable_extension "heroku_ext.pgcrypto" enable_extension "pg_stat_statements"

SQLite3Adapter: Bulk insert fixtures.
Previously one insert command was executed for each fixture, now they are aggregated in a single bulk insert command.
Lázaro Nixon
PostgreSQLAdapter: Allow
disable_extension
to be called with schema-qualified name.For parity with
enable_extension
, thedisable_extension
method can be called with a schema-qualified name (e.g.disable_extension "myschema.pgcrypto"
). Note that PostgreSQL'sDROP EXTENSION
does not actually take a schema name (unlikeCREATE EXTENSION
), so the resulting SQL statement will only name the extension, e.g.DROP EXTENSION IF EXISTS "pgcrypto"

option to customize the compression algorithm used.module ZstdCompressor def self.deflate(data) Zstd.compress(data) end def self.inflate(data) Zstd.decompress(data) end end class User encrypts :name, compressor: ZstdCompressor end
You disable compression by passing

Improve
::ActiveRecord::Store
to raise a descriptive exception if the column is not either structured (e.g., PostgreSQLhstore+/+json
, or MySQLjson
) or declared serializable viaActiveRecord.store
.Previously, a
NoMethodError
would be raised when the accessor was read or written:NoMethodError: undefined method `accessor' for an instance of ActiveRecord::Type::Text
Now, a descriptive
ConfigurationError
is raised:ActiveRecord::ConfigurationError: the column 'metadata' has not been configured as a store. Please make sure the column is declared serializable via 'ActiveRecord.store' or, if your database supports it, use a structured column type like hstore or json.

Fix inference of association model on nested models with the same demodularized name.
E.g. with the following setup:
class Nested::Post < ApplicationRecord has_one :post, through: :other end
Before,

would infer the model asNested::Post
, but now it correctly infersPost
.Joshua Young
Add public method for checking if a table is ignored by the schema cache.
Previously, an application would need to reimplement
ignored_table?
from the schema cache class to check if a table was set to be ignored. This adds a public method to support this and updates the schema cache to use that directly.ActiveRecord.schema_cache_ignored_tables = ["developers"] ActiveRecord.schema_cache_ignored_table?("developers") #=> true
