Papertrail

• First install PaperTrail and PaperTrail-AssociationTracking

Note: you should use the --with-changes option when creating the version table
to ensure that history messages are recorded in a object_changes column.

$ bundle exec rails generate paper_trail:install --with-changes
$ bundle exec rails generate paper_trail_association_tracking:install --with-associations

• add the has_paper_trail statements to the tracked models
• add this to your rails_admin.rb initializer:

config.audit_with :paper_trail, 'User', 'PaperTrail::Version' # PaperTrail >= 3.0.0
config.audit_with :paper_trail, 'User', 'Version' # PaperTrail < 3.0.0

User should be your 'whodunnit' model.

To show the history:

PAPER_TRAIL_AUDIT_MODEL = ['Order', 'Payment']
config.actions do
  history_index do
    only PAPER_TRAIL_AUDIT_MODEL
  end
  history_show do
    only PAPER_TRAIL_AUDIT_MODEL
  end
end

To hide the Papertrail links from the side navigation add this to your rails_admin.rb initializer:

  config.model "PaperTrail::Version" do
    visible false
  end

  config.model "PaperTrail::VersionAssociation" do
    visible false
  end
