• Remove warning message when running SQLite in production, but leave it unconfigured

  There are valid use cases for running SQLite in production, however it must be done with care, so instead of a warning most users won't see anyway, it's preferable to leave the configuration commented out to force them to think about having the database on a persistent volume etc.

• Add support for generated columns in SQLite3 adapter

  Generated columns (both stored and dynamic) are supported since version 3.31.0 of SQLite. This adds support for those to the SQLite3 adapter.

  create_table :users do |t|
    t.string :name
    t.virtual :name_upper, type: :string, as: 'UPPER(name)'
    t.virtual :name_lower, type: :string, as: 'LOWER(name)', stored: true
  end

• TrilogyAdapter: ignore host if socket parameter is set.

  This allows to configure a connection on a UNIX socket via DATABASE_URL:

  DATABASE_URL=trilogy://does-not-matter/my_db_production?socket=/var/run/mysql.sock

• Make assert_queries_count, assert_no_queries, assert_queries_match and assert_no_queries_match assertions public.

  To assert the expected number of queries are made, Rails internally uses assert_queries_count and assert_no_queries. To assert that specific SQL queries are made, assert_queries_match and assert_no_queries_match are used. These assertions can now be used in applications as well.

  class ArticleTest < ActiveSupport::TestCase
    test "queries are made" do
      assert_queries_count(1) { Article.first }
    end
  
    test "creates a foreign key" do
      assert_queries_match(/ADD FOREIGN KEY/i, include_schema: true) do
        @connection.add_foreign_key(:comments, :posts)
      end
    end
  end

• Fix has_secure_token calls the setter method on initialize.

• When using a DATABASE_URL, allow for a configuration to map the protocol in the URL to a specific database adapter. This allows decoupling the adapter the application chooses to use from the database connection details set in the deployment environment.

  # ENV['DATABASE_URL'] = "mysql://localhost/example_database"
  config.active_record.protocol_adapters.mysql = "trilogy"
  # will connect to MySQL using the trilogy adapter

• In cases where MySQL returns warning_count greater than zero, but returns no warnings when the SHOW WARNINGS query is executed, ActiveRecord.db_warnings_action proc will still be called with a generic warning message rather than silently ignoring the warning(s).

• DatabaseConfigurations#configs_for can accept a symbol in the name parameter.

• Fix where(field: values) queries when field is a serialized attribute (for example, when field uses ActiveRecord::Base.serialize or is a JSON column).

  João Alves

• Make the output of ActiveRecord::Core#inspect configurable.

  By default, calling inspect on a record will yield a formatted string including just the id.

  Post.first.inspect #=> "#<Post id: 1>"
  

  The attributes to be included in the output of inspect can be configured with ActiveRecord::Core#attributes_for_inspect.

  Post.attributes_for_inspect = [:id, :title]
  Post.first.inspect #=> "#<Post id: 1, title: "Hello, World!">"
  

  With the attributes_for_inspect set to :all, inspect will list all the record's attributes.

  Post.attributes_for_inspect = :all
  Post.first.inspect #=> "#<Post id: 1, title: "Hello, World!", published_at: "2023-10-23 14:28:11 +0000">"
  

  In development and test mode, attributes_for_inspect will be set to :all by default.

  You can also call full_inspect to get an inspection with all the attributes.

  The attributes in attribute_for_inspect will also be used for pretty_print.

• Don't mark Float::INFINITY as changed when reassigning it

  When saving a record with a float infinite value, it shouldn't mark as changed

• Support RETURNING clause for MariaDB

• The SQLite3 adapter now implements the supports_deferrable_constraints? contract

  Allows foreign keys to be deferred by adding the :deferrable key to the foreign_key options.

  add_reference :person, :alias, foreign_key: { deferrable: :deferred }
  add_reference :alias, :person, foreign_key: { deferrable: :deferred }
  

  Stephen Margheim

• Add set_constraints helper for PostgreSQL

  Post.create!(user_id: -1) # => ActiveRecord::InvalidForeignKey
  
  Post.transaction do
    Post.connection.set_constraints(:deferred)
    p = Post.create!(user_id: -1)
    u = User.create!
    p.user = u
    p.save!
  end
  

  Cody Cutrer

• Include ActiveModel::API in ActiveRecord::Base

  Sean Doyle

• Ensure #signed_id outputs url_safe strings.

  Jason Meller

• Add nulls_last and working desc.nulls_first for MySQL.
