v6.1.5: 6.1.5

Compare Source

Active Support

• Fix ActiveSupport::Duration.build to support negative values.

  The algorithm to collect the parts of the ActiveSupport::Duration
  ignored the sign of the value and accumulated incorrect part values. This
  impacted ActiveSupport::Duration#sum (which is dependent on parts) but
  not ActiveSupport::Duration#eql? (which is dependent on value).

  Caleb Buxton, Braden Staudacher

• Time#change and methods that call it (eg. Time#advance) will now
  return a Time with the timezone argument provided, if the caller was
  initialized with a timezone argument.

  Fixes #​42467.

  Alex Ghiculescu

• Clone to keep extended Logger methods for tagged logger.

  Orhan Toy

• assert_changes works on including ActiveSupport::Assertions module.

  Pedro Medeiros

Active Model

• Clear secure password cache if password is set to nil

  Before:

  user.password = 'something'
  user.password = nil

  user.password # => 'something'

  Now:

  user.password = 'something'
  user.password = nil

  user.password # => nil

  Markus Doits

• Fix delegation in ActiveModel::Type::Registry#lookup and ActiveModel::Type.lookup

  Passing a last positional argument {} would be incorrectly considered as keyword argument.

  Benoit Daloze

• Fix to_json after changes_applied for ActiveModel::Dirty object.

  Ryuta Kamizono

Active Record

• Fix ActiveRecord::ConnectionAdapters::SchemaCache#deep_deduplicate for Ruby 2.6.

  Ruby 2.6 and 2.7 have slightly different implementations of the String#@​- method.
  In Ruby 2.6, the receiver of the String#@​- method is modified under certain circumstances.
  This was later identified as a bug (https://bugs.ruby-lang.org/issues/15926) and only
  fixed in Ruby 2.7.

  Before the changes in this commit, the
  ActiveRecord::ConnectionAdapters::SchemaCache#deep_deduplicate method, which internally
  calls the String#@​- method, could also modify an input string argument in Ruby 2.6 --
  changing a tainted, unfrozen string into a tainted, frozen string.

  Fixes #​43056

  Eric O'Hanlon

• Fix migration compatibility to create SQLite references/belongs_to column as integer when
  migration version is 6.0.

  reference/belongs_to in migrations with version 6.0 were creating columns as
  bigint instead of integer for the SQLite Adapter.

  Marcelo Lauxen

• Fix dbconsole for 3-tier config.

  Eileen M. Uchitelle

• Better handle SQL queries with invalid encoding.

  Post.create(name: "broken \xC8 UTF-8")

  Would cause all adapters to fail in a non controlled way in the code
  responsible to detect write queries.

  The query is now properly passed to the database connection, which might or might
  not be able to handle it, but will either succeed or failed in a more correct way.

  Jean Boussier

• Ignore persisted in-memory records when merging target lists.

  Kevin Sjöberg

• Fix regression bug that caused ignoring additional conditions for preloading
  has_many through relations.

  Fixes #​43132

  Alexander Pauly

• Fix ActiveRecord::InternalMetadata to not be broken by
  config.active_record.record_timestamps = false

  Since the model always create the timestamp columns, it has to set them, otherwise it breaks
  various DB management tasks.

  Fixes #​42983

  Jean Boussier

• Fix duplicate active record objects on inverse_of.

  Justin Carvalho

• Fix duplicate objects stored in has many association after save.

  Fixes #​42549.

  Alex Ghiculescu

• Fix performance regression in CollectionAssocation#build.

  Alex Ghiculescu

• Fix retrieving default value for text column for MariaDB.

  fatkodima

Action View

• preload_link_tag properly inserts as attributes for files with image MIME
  types, such as JPG or SVG.

  Nate Berkopec

• Add autocomplete="off" to all generated hidden fields.

  Fixes #​42610.

  Ryan Baumann

• Fix current_page? when URL has trailing slash.

  This fixes the current_page? helper when the given URL has a trailing slash,
  and is an absolute URL or also has query params.

  Fixes #​33956.

  Jonathan Hefner

Action Pack

• Fix content_security_policy returning invalid directives.

  Directives such as self, unsafe-eval and few others were not
  single quoted when the directive was the result of calling a lambda
  returning an array.

  content_security_policy do |policy|
    policy.frame_ancestors lambda { [:self, "https://example.com"] }
  end

  With this fix the policy generated from above will now be valid.

  Edouard Chin

• Update HostAuthorization middleware to render debug info only
  when config.consider_all_requests_local is set to true.

  Also, blocked host info is always logged with level error.

  Fixes #​42813.

  Nikita Vyrko

• Dup arrays that get "converted".

  Fixes #​43681.

  Petrik de Heus

• Add more detail about what hosts are allowed.

  Alex Ghiculescu

Active Job

• No changes.

Action Mailer

• No changes.

Action Cable

• The Action Cable client now ensures successful channel subscriptions:

  • The client maintains a set of pending subscriptions until either
    the server confirms the subscription or the channel is torn down.
  • Rectifies the race condition where an unsubscribe is rapidly followed
    by a subscribe (on the same channel identifier) and the requests are
    handled out of order by the ActionCable server, thereby ignoring the
    subscribe command.

  Daniel Spinosa

• Truncate broadcast logging messages.

  J Smith

Active Storage

• Attachments can be deleted after their association is no longer defined.

  Fixes #​42514

  Don Sisco

Action Mailbox

• Add attachments to the list of permitted parameters for inbound emails conductor.

  When using the conductor to test inbound emails with attachments, this prevents an
  unpermitted parameter warning in default configurations, and prevents errors for
  applications that set:

  config.action_controller.action_on_unpermitted_parameters = :raise

  David Jones, Dana Henke

Action Text

• Fix Action Text extra trix content wrapper.

  Alexandre Ruban

Railties

• In zeitwerk mode, setup the once autoloader first, and the main autoloader after it.
  This order plays better with shared namespaces.

  Xavier Noria

• Handle paths with spaces when editing credentials.

  Alex Ghiculescu

  Exclude +mutations_from_database+ attribute from json as it lead to recursion.

  Anil Maurya

Active Record

• Do not try to rollback transactions that failed due to a ActiveRecord::TransactionRollbackError.

  Jamie McCarthy

• Raise an error if pool_config is nil in set_pool_config.

  Eileen M. Uchitelle

• Fix compatibility with psych >= 4.

  Starting in Psych 4.0.0 YAML.load behaves like YAML.safe_load. To preserve compatibility
  Active Record's schema cache loader and YAMLColumn now uses YAML.unsafe_load if available.

  Jean Boussier

• Support using replicas when using rails dbconsole.

  Christopher Thornton

• Restore connection pools after transactional tests.

  Eugene Kenny

• Change upsert_all to fails cleanly for MySQL when :unique_by is used.

  Bastian Bartmann

• Fix user-defined self.default_scope to respect table alias.

  Ryuta Kamizono

• Clear @cache_keys cache after update_all, delete_all, destroy_all.

  Ryuta Kamizono

• Changed Arel predications contains and overlaps to use
  quoted_node so that PostgreSQL arrays are quoted properly.

  Bradley Priest

• Fix merge when the where clauses have string contents.

  Ryuta Kamizono

• Fix rollback of parent destruction with nested dependent: :destroy.

  Jacopo Beschi

• Fix binds logging for "WHERE ... IN ..." statements.

  Ricardo Díaz

• Handle false in relation strict loading checks.

  Previously when a model had strict loading set to true and then had a
  relation set strict_loading to false the false wasn't considered when
  deciding whether to raise/warn about strict loading.

  class Dog < ActiveRecord::Base
    self.strict_loading_by_default = true
  
    has_many :treats, strict_loading: false
  end
  

  In the example, dog.treats would still raise even though
  strict_loading was set to false. This is a bug effecting more than
  Active Storage which is why I made this PR superceeding #​41461. We need
  to fix this for all applications since the behavior is a little
  surprising. I took the test from ##​41461 and the code suggestion from #​41453
  with some additions.

  Eileen M. Uchitelle, Radamés Roriz

  David Heinemeier Hansson

• Allow both current_page?(url_hash) and current_page?(**url_hash) on Ruby 2.7.

  Ryuta Kamizono

Action Pack

• Ignore file fixtures on db:fixtures:load

  Kevin Sjöberg

• Fix ActionController::Live controller test deadlocks by removing the body buffer size limit for tests.

  Dylan Thacker-Smith

• Correctly place optional path parameter booleans.

  Previously, if you specify a url parameter that is part of the path as false it would include that part
  of the path as parameter for example:

  get "(/optional/:optional_id)/things" => "foo#foo", as: :things
  things_path(optional_id: false) # => /things?optional_id=false
  

  After this change, true and false will be treated the same when used as optional path parameters. Meaning now:

  get '(this/:my_bool)/that' as: :that
  
  that_path(my_bool: true) # => `/this/true/that`
  that_path(my_bool: false) # => `/this/false/that`
  

  Adam Hess

  Starting in Psych 4.0.0 YAML.load behaves like YAML.safe_load. To preserve compatibility
  Rails.application.config_for now uses YAML.unsafe_load if available.

  Jean Boussier

• Ensure Rails.application.config_for always cast hashes to ActiveSupport::OrderedOptions.

  Jean Boussier

• Fix create migration generator with --pretend option.

Active Support

  to the connection session.

  Rafael Mendonça França

• Fix MySQL adapter handling of time objects when prepared statements
  are enabled.

  Rafael Mendonça França

• Fix scoping in enum fields using conditions that would generate
  an IN clause.

  Ryuta Kamizono

• Skip optimised #exist? query when #include? is called on a relation
  with a having clause

  Relations that have aliased select values AND a having clause that
  references an aliased select value would generate an error when
  #include? was called, due to an optimisation that would generate
  call #exists? on the relation instead, which effectively alters
  the select values of the query (and thus removes the aliased select
  values), but leaves the having clause intact. Because the having
  clause is then referencing an aliased column that is no longer
  present in the simplified query, an ActiveRecord::InvalidStatement
  error was raised.

  An sample query affected by this problem:

  Author.select('COUNT(*) as total_posts', 'authors.*')
        .joins(:posts)
        .group(:id)
        .having('total_posts > 2')
        .include?(Author.first)

  This change adds an addition check to the condition that skips the
  simplified #exists? query, which simply checks for the presence of
  a having clause.

  Fixes #​41417

  Michael Smart

• Increment postgres prepared statement counter before making a prepared statement, so if the statement is aborted
  without Rails knowledge (e.g., if app gets kill -9d during long-running query or due to Rack::Timeout), app won't end
  up in perpetual crash state for being inconsistent with Postgres.

Active Support

• ActiveSupport::Cache::MemCacheStore now accepts an explicit nil for its addresses argument.

  config.cache_store = :mem_cache_store, nil

is now equivalent to

config.cache_store = :mem_cache_store

and is also equivalent to

config.cache_store = :mem_cache_store, ENV["MEMCACHE_SERVERS"] || "localhost:11211"

which is the fallback behavior of Dalli

```

This helps those migrating from `:dalli_store`, where an explicit `nil` was permitted.

*Michael Overmeyer*

Active Model

Active Record

• Fix timestamp type for sqlite3.

  Eileen M. Uchitelle

• Make destroy async transactional.

  An active record rollback could occur while enqueuing a job. In this
  case the job would enqueue even though the database deletion
  rolledback putting things in a funky state.

  Now the jobs are only enqueued until after the db transaction has been committed.

  Cory Gwin

• Fix malformed packet error in MySQL statement for connection configuration.

  robinroestenburg

• Connection specification now passes the "url" key as a configuration for the
  adapter if the "url" protocol is "jdbc", "http", or "https". Previously only
  urls with the "jdbc" prefix were passed to the Active Record Adapter, others
  are assumed to be adapter specification urls.

  MemoryStore to its prior rails 5.1 behavior.

  Max Gurewitz

• Calling iso8601 on negative durations retains the negative sign on individual

• ActiveSupport::Subscriber#attach_to now accepts an inherit_all: argument. When set to true,
  it allows a subscriber to receive events for methods defined in the subscriber's ancestor class(es).

    attach_to :action_controller
  
    def start_processing(event)
      info "Processing by #{event.payload[:controller]}##{event.payload[:action]} as #{format}"
    end
  
    def redirect_to(event)
      info { "Redirected to #{event.payload[:location]}" }
    end
  end

We detach ActionControllerSubscriber from the :action_controller namespace so that our CustomActionControllerSubscriber

can provide its own instrumentation for certain events in the namespace

ActionControllerSubscriber.detach_from(:action_controller)

class CustomActionControllerSubscriber < ActionControllerSubscriber
  attach_to :action_controller, inherit_all: true

  def start_processing(event)
    info "A custom response to start_processing events"
  end

=> CustomActionControllerSubscriber will process events for "start_processing.action_controller" notifications

using its own #start_processing implementation, while retaining ActionControllerSubscriber's instrumentation

for "redirect_to.action_controller" notifications

end

• Add override of unary plus for ActiveSupport::Duration.

• Align Range#cover? extension behavior with Ruby behavior for backwards ranges.

  (1..10).cover?(5..3) now returns false, as it does in plain Ruby.

  Also update #include? and #=== behavior to match.

  Michael Groeneman

• Update to TZInfo v2.0.0.

  This changes the output of ActiveSupport::TimeZone.utc_to_local, but
  can be controlled with the
  ActiveSupport.utc_to_local_returns_utc_offset_times config.

  New Rails 6.1 apps have it enabled by default, existing apps can upgrade
  via the config in config/initializers/new_framework_defaults_6_1.rb

  See the utc_to_local_returns_utc_offset_times documentation for details.

• [Breaking change] ActiveSupport::Callbacks#halted_callback_hook now receive a 2nd argument:

  ActiveSupport::Callbacks#halted_callback_hook now receive the name of the callback
  being halted as second argument.
  This change will allow you to differentiate which callbacks halted the chain
  and act accordingly.

    class Book < ApplicationRecord
      before_save { throw(:abort) }
      before_create { throw(:abort) }
  
      def halted_callback_hook(filter, callback_name)
        Rails.logger.info("Book couldn't be #{callback_name}d")

• Support prepend with ActiveSupport::Concern.

  Allows a module with extend ActiveSupport::Concern to be prepended.

  module Imposter
    extend ActiveSupport::Concern
  

Same as included, except only run when prepended.

      prepended do
      end
    end

    class Person
      prepend Imposter
    end

Class methods are prepended to the base class, concerning is also
updated: `concerning :Imposter, prepend: true do`.

• Support added for a round_mode parameter, in all number helpers. (See: BigDecimal::mode.)

  number_to_currency(1234567890.50, precision: 0, round_mode: :half_down) # => "$1,234,567,890"
  number_to_percentage(302.24398923423, precision: 5, round_mode: :down) # => "302.24398%"

• When an instance of ActiveSupport::Duration is converted to an iso8601 duration string, if weeks are mixed with date parts, the week part will be converted to days.
  This keeps the parser and serializer on the same page.

  duration = ActiveSupport::Duration.build(1000000)

1 week, 4 days, 13 hours, 46 minutes, and 40.0 seconds

duration_iso = duration.iso8601

• Prevent ActiveSupport::Duration.build(value) from creating instances of
  ActiveSupport::Duration unless value is of type Numeric.

  Addresses the errant set of behaviours described in #​37012 where
  ActiveSupport::Duration comparisons would fail confusingly
  or return unexpected results when comparing durations built from instances of String.

  Before:

  small_duration_from_string = ActiveSupport::Duration.build('9')
  large_duration_from_string = ActiveSupport::Duration.build('100000000000000')
  small_duration_from_int = ActiveSupport::Duration.build(9)
  
  large_duration_from_string > small_duration_from_string
  

=> false

    small_duration_from_string == small_duration_from_int

=> false

    small_duration_from_int < large_duration_from_string

=> ArgumentError (comparison of ActiveSupport::Duration::Scalar with ActiveSupport::Duration failed)

    large_duration_from_string > small_duration_from_int

=> ArgumentError (comparison of String with ActiveSupport::Duration failed)

After:

    small_duration_from_string = ActiveSupport::Duration.build('9')

=> TypeError (can't build an ActiveSupport::Duration from a String)

• Add compact_blank for those times when you want to remove #blank? values from
  an Enumerable (also compact_blank! on Hash, Array, ActionController::Parameters).

  Dana Sherson

• Make ActiveSupport::Logger Fiber-safe.

  Use Fiber.current.__id__ in ActiveSupport::Logger#local_level= in order
  to make log level local to Ruby Fibers in addition to Threads.

  Example:

  logger = ActiveSupport::Logger.new(STDOUT)
  logger.level = 1
  puts "Main is debug? #{logger.debug?}"
  
  Fiber.new {
    logger.local_level = 0
    puts "Thread is debug? #{logger.debug?}"
  }.resume
  
  puts "Main is debug? #{logger.debug?}"
  

  Before:

  Main is debug? false
  Thread is debug? true
  Main is debug? true
  

  After:

  Main is debug? false
  Thread is debug? true
  Main is debug? false
  

  Fixes #​36752.

• Allow the on_rotation proc used when decrypting/verifying a message to be
  passed at the constructor level.

  Before:

  crypt = ActiveSupport::MessageEncryptor.new('long_secret')
  crypt.decrypt_and_verify(encrypted_message, on_rotation: proc { ... })
  crypt.decrypt_and_verify(another_encrypted_message, on_rotation: proc { ... })
  

  After:

  crypt.decrypt_and_verify(encrypted_message)
  crypt.decrypt_and_verify(another_encrypted_message)

• delegate_missing_to would raise a DelegationError if the object
  delegated to was nil. Now the allow_nil option has been added to enable
  the user to specify they want nil returned in this case.

• truncate would return the original string if it was too short to be truncated
  and a frozen string if it were long enough to be truncated. Now truncate will
  consistently return an unfrozen string regardless. This behavior is consistent
  with gsub and strip.

  Before:

  'foobar'.truncate(5).frozen?
  

=> true

    'foobar'.truncate(6).frozen?

=> false

After:

    'foobar'.truncate(5).frozen?

=> false

    'foobar'.truncate(6).frozen?

=> false

• Pass in base instead of base_class to Error.human_attribute_name

  This is useful in cases where the human_attribute_name method depends
  on other attributes' values of the class under validation to derive what the
  attribute name should be.

• Raise FrozenError when trying to write attributes that aren't backed by the database on an object that is frozen:

  class Animal
    include ActiveModel::Attributes
    attribute :age
  end
  
  animal = Animal.new
  animal.freeze
  animal.age = 25 # => FrozenError, "can't modify a frozen Animal"
  

  Josh Brody

• Add *_previously_was attribute methods when dirty tracking. Example:

  pirate.update(catchphrase: "Ahoy!")
  pirate.previous_changes["catchphrase"] # => ["Thar She Blows!", "Ahoy!"]
  pirate.catchphrase_previously_was # => "Thar She Blows!"
  

  DHH

• Encapsulate each validation error as an Error object.

  The ActiveModel’s errors collection is now an array of these Error
  objects, instead of messages/details hash.

  For each of these Error object, its message and full_message methods
  are for generating error messages. Its details method would return error’s
  extra parameters, found in the original details hash.

  The change tries its best at maintaining backward compatibility, however
  some edge cases won’t be covered, like errors#first will return ActiveModel::Error and manipulating
  errors.messages and errors.details hashes directly will have no effect. Moving forward,
  please convert those direct manipulations to use provided API methods instead.

  The list of deprecated methods and their planned future behavioral changes at the next major release are:

  • errors#slice! will be removed.
  • errors#each with the key, value two-arguments block will stop working, while the error single-argument block would return Error object.
  • errors#values will be removed.
  • errors#keys will be removed.
  • errors#to_xml will be removed.
  • errors#to_h will be removed, and can be replaced with errors#to_hash.
  • Manipulating errors itself as a hash will have no effect (e.g. errors[:foo] = 'bar').
  • Manipulating the hash returned by errors#messages (e.g. errors.messages[:foo] = 'bar') will have no effect.
  • Manipulating the hash returned by errors#details (e.g. errors.details[:foo].clear) will have no effect.

• Add connected_to_many API.

  This API allows applications to connect to multiple databases at once without switching all of them or implementing a deeply nested stack.

  Before:

  AnimalsRecord.connected_to(role: :reading) do
  MealsRecord.connected_to(role: :reading) do
  Dog.first # read from animals replica
  Dinner.first # read from meals replica
  Person.first # read from primary writer
  end
  end

  After:

  Dog.first # read from animals replica
  Dinner.first # read from meals replica
  Person.first # read from primary writer
  end

• Add option to raise or log for ActiveRecord::StrictLoadingViolationError.

  Some applications may not want to raise an error in production if using strict_loading. This would allow an application to set strict loading to log for the production environment while still raising in development and test environments.

  Set config.active_record.action_on_strict_loading_violation to :log errors instead of raising.

• Allow the inverse of a has_one association that was previously autosaved to be loaded.

  Fixes #​34255.

  Steven Weber

• Optimise the length of index names for polymorphic references by using the reference name rather than the type and id column names.

  Because the default behaviour when adding an index with multiple columns is to use all column names in the index name, this could frequently lead to overly long index names for polymorphic references which would fail the migration if it exceeded the database limit.

  This change reduces the chance of that happening by using the reference name, e.g. index_my_table_on_my_reference.

  Fixes #​38655.

• Connections can be granularly switched for abstract classes when connected_to is called.

  This change allows connected_to to switch a role and/or shard for a single abstract class instead of all classes globally. Applications that want to use the new feature need to set config.active_record.legacy_connection_handling to false in their application configuration.

  Example usage:

  Given an application we have a User model that inherits from ApplicationRecord and a Dog model that inherits from AnimalsRecord. AnimalsRecord and ApplicationRecord have writing and reading connections as well as shard default, one, and two.

  ActiveRecord::Base.connected_to(role: :reading) do
    User.first # reads from default replica
    Dog.first # reads from default replica
  
    AnimalsRecord.connected_to(role: :writing, shard: :one) do
      User.first # reads from default replica
      Dog.first # reads from shard one primary
    end
  
    User.first # reads from default replica
    Dog.first # reads from default replica
  
    ApplicationRecord.connected_to(role: :writing, shard: :two) do
      User.first # reads from shard two primary
      Dog.first # reads from default replica
    end
  end

• Add support for PostgreSQL interval data type with conversion to
  ActiveSupport::Duration when loading records from database and
  serialization to ISO 8601 formatted duration string on save.
  Add support to define a column in migrations and get it in a schema dump.
  Optional column precision is supported.

  To use this in 6.1, you need to place the next string to your model file:

  attribute :duration, :interval
  

  To keep old behavior until 6.2 is released:

  attribute :duration, :string
  

  Example:

  create_table :events do |t|
    t.string   :name
    t.interval :duration
  end
  
  class Event < ApplicationRecord
    attribute :duration, :interval
  end
  
  Event.create!(name: 'Rock Fest', duration: 2.days)
  Event.last.duration # => 2 days
  Event.last.duration.iso8601 # => "P2D"
  Event.new(duration: 'P1DT12H3S').duration # => 1 day, 12 hours, and 3 seconds
  Event.new(duration: '1 day') # Unknown value will be ignored and NULL will be written to database
