Audited (previously acts_as_audited) is an ORM extension that logs all changes to your models. Audited can also record who made those changes, save comments and associate models related to the changes.
Audited currently (5.6) works with Rails 7.1, 7.0, 6.1, 6.0, 5.2.
For Rails 5.0 & 5.1, use gem version 5.4.3 For Rails 4, use gem version 4.x For Rails 3, use gem version 3.0 or see the 3.0-stable branch.
Audited supports and is tested against the following Ruby versions:
- 2.3 (only tested on Sqlite due to testing issues with other DBs)
- 2.4
- 2.5
- 2.6
- 2.7
- 3.0
- 3.1
- 3.2
Audited may work just fine with a Ruby version not listed above, but we can't guarantee that it will. If you'd like to maintain a Ruby that isn't listed, please let us know with a pull request.
Audited is currently ActiveRecord-only. In a previous life, Audited worked with MongoMapper. Use the 4.2-stable branch if you need MongoMapper.
Add the gem to your Gemfile:
gem "audited"And if you're using require: false you must add initializers like this:
#./config/initializers/audited.rb
require "audited"
Audited::Railtie.initializers.each(&:run)Then, from your Rails app directory, create the audits table:
$ rails generate audited:install
$ rake db:migrateBy default changes are stored in YAML format. If you're using PostgreSQL, then you can use rails generate audited:install --audited-changes-column-type jsonb (or json for MySQL 5.7+ and Rails 5+) to store audit changes natively with database JSON column types.
If you're using something other than integer primary keys (e.g. UUID) for your User model, then you can use rails generate audited:install --audited-user-id-column-type uuid to customize the audits table user_id column type.
If you're already using Audited (or acts_as_audited), your audits table may require additional columns. After every upgrade, please run:
$ rails generate audited:upgrade
$ rake db:migrateUpgrading will only make changes if changes are needed.
Simply call audited on your models:
class User < ActiveRecord::Base
audited
endBy default, whenever a user is created, updated or destroyed, a new audit is created.
user = User.create!(name: "Steve")
user.audits.count # => 1
user.update!(name: "Ryan")
user.audits.count # => 2
user.destroy
user.audits.count # => 3Audits contain information regarding what action was taken on the model and what changes were made.
user.update!(name: "Ryan")
audit = user.audits.last
audit.action # => "update"
audit.audited_changes # => {"name"=>["Steve", "Ryan"]}You can get previous versions of a record by index or date, or list all revisions.
user.revisions
user.revision(1)
user.revision_at(Date.parse("2016-01-01"))By default, a new audit is created for any attribute changes. You can, however, limit the columns to be considered.
class User < ActiveRecord::Base
# All fields
# audited
# Single field
# audited only: :name
# Multiple fields
# audited only: [:name, :address]
# All except certain fields
# audited except: :password
endBy default, a new audit is created for any Create, Update, Touch (Rails 6+) or Destroy action. You can, however, limit the actions audited.
class User < ActiveRecord::Base
# All fields and actions
# audited
# Single field, only audit Update and Destroy (not Create or Touch)
# audited only: :name, on: [:update, :destroy]
endYou can ignore the default callbacks globally unless the callback action is specified in your model using the :on option. To configure default callback exclusion, put the following in an initializer file (config/initializers/audited.rb):
Audited.ignored_default_callbacks = [:create, :update] # ignore callbacks create and updateYou can attach comments to each audit using an audit_comment attribute on your model.
user.update!(name: "Ryan", audit_comment: "Changing name, just because")
user.audits.last.comment # => "Changing name, just because"You can optionally add the :comment_required option to your audited call to require comments for all audits.
class User < ActiveRecord::Base
audited :comment_required => true
endYou can update an audit only if audit_comment is present. You can optionally add the :update_with_comment_only option set to false to your audited call to turn this behavior off for all audits.
class User < ActiveRecord::Base
audited :update_with_comment_only => false
endYou can limit the number of audits stored for your model. To configure limiting for all audited models, put the following in an initializer file (config/initializers/audited.rb):
Audited.max_audits = 10 # keep only 10 latest auditsor customize per model:
class User < ActiveRecord::Base
audited max_audits: 2
endWhenever an object is updated or destroyed, extra audits are combined with newer ones and the old ones are destroyed.
user = User.create!(name: "Steve")
user.audits.count # => 1
user.update!(name: "Ryan")
user.audits.count # => 2
user.destroy
user.audits.count # => 2If you're using Audited in a Rails application, all audited changes made within a request will automatically be attributed to the current user. By default, Audited uses the current_user method in your controller.
class PostsController < ApplicationController
def create
current_user # => #<User name: "Steve">
@post = Post.create(params[:post])
@post.audits.last.user # => #<User name: "Steve">
end
endTo use a method other than current_user, put the following in an initializer file (config/initializers/audited.rb):
Audited.current_user_method = :authenticated_userOutside of a request, Audited can still record the user with the as_user method:
Audited.audit_class.as_user(User.find(1)) do
post.update!(title: "Hello, world!")
end
post.audits.last.user # => #<User id: 1>The standard Audited install assumes your User model has an integer primary key type. If this isn't true (e.g. you're using UUID primary keys), you'll need to create a migration to update the audits table user_id column type. (See Installation above for generator flags if you'd like to regenerate the install migration.)
You might need to use a custom auditor from time to time. This can be done by simply passing in a string:
class ApplicationController < ActionController::Base
def authenticated_user
if current_user
current_user
else
'Alexander Fleming'
end
end
endas_user also accepts a string, which can be useful for auditing updates made in a CLI environment:
Audited.audit_class.as_user("console-user-#{ENV['SSH_USER']}") do
post.update_attributes!(title: "Hello, world!")
end
post.audits.last.user # => 'console-user-username'If you want to set a specific user as the auditor of the commands in a CLI environment, whether that is a string or an ActiveRecord object, you can use the following command:
Audited.store[:audited_user] = "username"
# or
Audited.store[:audited_user] = User.find(1)Sometimes it's useful to associate an audit with a model other than the one being changed. For instance, given the following models:
class User < ActiveRecord::Base
belongs_to :company
audited
end
class Company < ActiveRecord::Base
has_many :users
endEvery change to a user is audited, but what if you want to grab all of the audits of users belonging to a particular company? You can add the :associated_with option to your audited call:
class User < ActiveRecord::Base
belongs_to :company
audited associated_with: :company
end
class Company < ActiveRecord::Base
audited
has_many :users
has_associated_audits
endNow, when an audit is created for a user, that user's company is also saved alongside the audit. This makes it much easier (and faster) to access audits indirectly related to a company.
company = Company.create!(name: "Collective Idea")
user = company.users.create!(name: "Steve")
user.update!(name: "Steve Richert")
user.audits.last.associated # => #<Company name: "Collective Idea">
company.associated_audits.last.auditable # => #<User name: "Steve Richert">You can access records' own audits and associated audits in one go:
company.own_and_associated_auditsIf you want to audit only under specific conditions, you can provide conditional options (similar to ActiveModel callbacks) that will ensure your model is only audited for these conditions.
class User < ActiveRecord::Base
audited if: :active?
def active?
last_login > 6.months.ago
end
endJust like in ActiveModel, you can use an inline Proc in your conditions:
class User < ActiveRecord::Base
audited unless: Proc.new { |u| u.ninja? }
endIn the above case, the user will only be audited when User#ninja is false.
If you want to disable auditing temporarily doing certain tasks, there are a few methods available.
To disable auditing on a save:
@user.save_without_auditingor:
@user.without_auditing do
@user.save
endTo disable auditing on a column:
User.non_audited_columns = [:first_name, :last_name]To disable auditing on an entire model:
User.auditing_enabled = falseTo disable auditing on all models:
Audited.auditing_enabled = falseIf you have auditing disabled by default on your model you can enable auditing temporarily.
User.auditing_enabled = false
@user.save_with_auditingor:
User.auditing_enabled = false
@user.with_auditing do
@user.save
endIf you're using ActiveRecord's encryption (available from Rails 7) to encrypt some attributes, Audited will automatically filter values of these attributes. No additional configuration is required. Changes to encrypted attributes will be logged as [FILTERED].
class User < ActiveRecord::Base
audited
encrypts :password
endIf you want to extend or modify the audit model, create a new class that
inherits from Audited::Audit:
class CustomAudit < Audited::Audit
def some_custom_behavior
"Hiya!"
end
endThen set it in an initializer:
# config/initializers/audited.rb
Audited.config do |config|
config.audit_class = "CustomAudit"
endIn 4.10, the default behavior for enums changed from storing the value synthesized by Rails to the value stored in the DB. You can restore the previous behavior by setting the store_synthesized_enums configuration value:
# config/initializers/audited.rb
Audited.store_synthesized_enums = trueYou can find documentation at: https://www.rubydoc.info/gems/audited
