Papertrail

• First install PaperTrail

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. Also specify --with-associations so that a version_associations table is created which tracks association changes.

$ bundle exec rails generate paper_trail:install --with-changes --with-associations
   Connecting to database specified by database.yml`
      create  db/migrate/20131113103143_create_versions.rb
      create  db/migrate/20131113103144_add_object_changes_column_to_versions.rb
      create  db/migrate/20131113103145_create_version_associations.rb

• 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 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
