Add “trackzored” to your model. By convention, any attribute that also has [ATTR]_updated_at or [ATTR]_updated_by will be maintained. You can optionally specify :only and :except if this convention steps on your toes – :except => :status would skip the check and update of status_updated_at and status_updated_by. If [ATTR]_updated_by is present, it is required by a validator. If acts_as_audited is present, trackzor-maintained columns will be added to non_audited_columns to prevent double-auditing.

Use the trackzor_migration generator to quickly add columns:

script/generate trackzor_migration User email phone_number

This will create a migration for adding email_updated_at, email_updated_by, phone_number_updated_at, and phone_number_updated_by columns.

To set the current user:

Trackzor.as_user(user_obj) do
  ...
end

Or, if you’re also using acts_as_audited, its as_user method is supported:

Audit.as_user(user_obj) do
  ...
end

For each trackzored [ATTR]_updated_by column, a belongs_to association (:[ATTR]_source) is added to link to the user.
