Audit Events for Items and Statistics

In order to calculate statistics data about the change history of items is saved in audit_events.

When more actions on items are added it is important to add the new audits for those events. In order to do this in the audit_event.rb model another event_type has to be added and in the audit_event_helper a new funktion has to be added.

Audited events are:

• create item
• request lend
• accept lend
• request return
• accept return
• deny return
• add to waitlist
• leave waitlist

Using these audits for statistics will be possible through the use of funktions in the statistics_helper.rb. When writing new statistic methods pleas name them beginning with "statistics_".
