paper-trail-gem--paper_trail/CHANGELOG.md

3.1.0 (Unreleased)

Breaking change: if you use a custom initializer for PaperTrail in conjunction with Rails, you will need to add this line of code to the beginning of it:

PaperTrail::Rails::Engine.eager_load!

• #427 - Fix reify method in context of model where a column has been removed.
• #414 - Fix functionality ignore argument to has_paper_trail in ActiveRecord 4.
• #399 - Add :dup argument for options hash to reify which forces a new model instance.
• #394 - Add RSpec matcher have_a_version_with for easier testing.
• #375 / #374 / #354 / #131 - Versions should be built with after_ callbacks so the timestamp field for a version can be forced to match the corresponding timestamp in the database for the state persistence of a change to the base (versioned) model.
• #347 - Autoload ActiveRecord models in via a Rails::Engine when the gem is used with Rails.
• Methods handling serialized attributes should fallback to the currently set Serializer instead of always falling back to PaperTrail::Serializers::YAML.

3.0.6

• #414 - Backport fix for ignore argument to has_paper_trail in ActiveRecord 4.

3.0.5

• #401 / #406 PaperTrail::Version class is not loaded via a Rails::Engine, even when the gem is used with in Rails. This feature has will be re-introduced in version 3.1.0.
• #398 - Only require the RSpec helper if RSpec::Core is required.

3.0.3

This version was yanked from RubyGems and has been replaced by version 3.0.5, which is almost identical, but does not eager load in the PaperTrail::Version class through a Rails::Engine when the gem is used on Rails since it was causing issues for some users.

• #386 - Fix eager loading of versions association with custom class name in ActiveRecord 4.1.
• #384 - Fix VersionConcern#originator instance method.
• #383 - Make gem compatible with ActiveRecord::Enum (available in ActiveRecord 4.1+).
• #380 / #377 - Add VersionConcern#where_object instance method; acts as a helper for querying against the object column in versions table.
• #373 - Fix default sort order for the versions association in ActiveRecord 4.1.
• #372 - Use Arel for SQL construction.
• #365 - VersionConcern#version_at should return nil when receiving a timestamp that occured after the object was destroyed.
• Expand PaperTrail::VERSION into a module, mimicking the form used by Rails to give it some additional modularity & versatility.
• Fixed VersionConcern#index instance method so that it conforms to using the primary key for ordering when possible.

3.0.2

• #357 - If a Version instance is reified and then persisted at that state, it's timestamp attributes for update should still get touched.
• #351 / #352 - PaperTrail::Rails::Controller should hook into all controller types, and should not get loaded unless ActionController is.
• #346 - user_for_paper_trail method should accommodate different types for return values from current_user method.
• #344 - Gem is now tested against MySQL and PostgreSQL in addition to SQLite.
• #317 / #314 - versions should default to ordering via the primary key if it is an integer to avoid timestamp comparison issues.
• PaperTrail::Cleaner.clean_versions! should group versions by PaperTrail.timestamp_field when deciding which ones to keep / destroy, instead of always grouping by the created_at field.
• If a Version instance is reified and then persisted at that state, it's source version (model_instance#version_association_name, usually model_instance#version) will get cleared since persisting it causes it to become the live instance.
• If destroy actions are tracked for a versioned model, invoking destroy on the model will cause the corresponding version that gets generated to be assigned as the source version (model_instance#version_association_name, usually model_instance#version).

3.0.1

• #340 - Prevent potential error encountered when using the InstallGenerator with Rails 4.1.0.rc1.
• #334 - Add small-scope whodunnit method to PaperTrail::Model::InstanceMethods.
• #329 - Add touch_with_version method to PaperTrail::Model::InstanceMethods, to allow for generating a version touching a model.
• #328 / #326 / #307 - Model.paper_trail_enabled_for_model? and model_instance.without_versioning is now thread-safe.
• #316 - user_for_paper_trail should default to current_user.try(:id) instead of current_user (if current_user is defined).
• #313 - Make the Rails::Controller helper compatible with ActionController::API for compatibility with the rails-api gem.
• #312 - Fix RSpec with_versioning class level helper method.
• model_instance.without_versioning now yields the model_instance, enabling syntax like this: model_instance.without_versioning { |obj| obj.update_attributes(:name => 'value') }.
• Deprecated Model.paper_trail_on and Model.paper_trail_off in favor of bang versions of the methods. Deprecation warning informs users that the non-bang versions of the methods will be removed in version 3.1.0.

3.0.0

• #305 - PaperTrail::VERSION should be loaded at runtime.
• #295 - Explicitly specify table name for version class when querying attributes. Prevents AmbiguousColumn errors on certain JOIN statements.
• #289 - Use ActiveSupport::Concern for implementation of base functionality on PaperTrail::Version class. Increases flexibility and makes it easier to use custom version classes with multiple ActiveRecord connections.
• #288 - Change all scope declarations to class methods on the PaperTrail::Version class. Fixes usability when PaperTrail::Version.abstract_class? == true.
• #287 - Support for PostgreSQL's JSON Type for storing object and object_changes.
• #281 - Rails::Controller helper will return false for the paper_trail_enabled_for_controller method if PaperTrail.enabled? == false.
• #280 - Don't track virtual timestamp attributes.
• #278 / #272 - Make RSpec and Cucumber helpers usable with Spork and Zeus.
• #273 - Make the only and ignore options accept Hash arguments; allows for conditional tracking.
• #264 - Allow unwrapped symbol to be passed in to the on option.
• #224/#236 - Fixed compatibility with ActsAsTaggableOn.
• #235 - Dropped unnecessary secondary sort on versions association.
• #216 - Added helper & extension for RSpec, and helper for Cucumber.
• #212 - Added PaperTrail::Cleaner module, useful for discarding draft versions.
• #207 - Versions for 'create' events are now created with create! instead of create so that an exception gets raised if it is appropriate to do so.
• #199 - Rails 4 compatibility.
• #165 - Namespaced the Version class under the PaperTrail module.
• #119 - Support for Sinatra; decoupled gem from Rails.
• Renamed the default serializers from PaperTrail::Serializers::Yaml and PaperTrail::Serializers::Json to the capitalized forms, PaperTrail::Serializers::YAML and PaperTrail::Serializers::JSON.
• Removed deprecated set_whodunnit method from Rails Controller scope.

2.7.2

• #228 - Refactored default user_for_paper_trail method implementation so that current_user only gets invoked if it is defined.
• #219 - Fixed issue where attributes stored with nil value might not get reified properly depending on the way the serializer worked.
• #213 - Added a version_limit option to the PaperTrail::Config options that can be used to restrict the number of versions PaperTrail will store per object instance.
• #187 - Confirmed JRuby support.
• #174 - The event field on the versions table can now be customized.

2.7.1

• #206 - Fixed Ruby 1.8.7 compatibility for tracking object_changes.
• #200 - Fixed next_version method so that it returns the live model when called on latest reified version of a model prior to the live model.
• #197 - PaperTrail now falls back on using YAML for serialization of serialized model attributes for storage in the object and object_changes columns in the Version table. This fixes compatibility for Rails 3.0.x for projects that employ the serialize declaration on a model.
• #194 - A JSON serializer is now included in the gem.
• #192 - object_changes should store serialized representation of serialized attributes for create actions (in addition to update actions, which had already been patched by #180).
• #190 - Fixed compatibility with SerializedAttributes gem.
• #189 - Provided support for a configure block initializer.
• Added setter method for the serializer config option.

2.7.0

• #183 - Fully qualify the Version class to help prevent namespace resolution errors within other gems / plugins.
• #180 - Store serialized representation of serialized attributes on the object and object_changes columns in the Version table.
• #164 - Allow usage of custom serializer for storage of object attributes.

2.6.4

• #181/#182 - Controller metadata methods should only be evaluated when paper_trail_enabled_for_controller == true.
• #177/#178 - Factored out version_key into it's own method to prevent ConnectionNotEstablished error from getting thrown in instances where has_paper_trail is declared on class prior to ActiveRecord establishing a connection.
• #176 - Force metadata calls for attributes to use current value if attribute value is changing.
• #173 - Update link to diff-lcs.
• #172 - Save object_changes on creation.
• #168 - Respect conditional :if or :unless arguments to the has_paper_trail method for destroy events.

• #160 - Fixed failing tests and resolved out of date dependency issues.
• #157 - Refactored class_attribute names on the ClassMethods module for names that are not obviously pertaining to PaperTrail to prevent method name collision.
