Description

Introduced in v3.14, this class will automatically calculate and roll up the ‘Booked Places’ of a Study Offering.

When a Study Registration:

• is created/updated against a Study Offering, and
• its Status is a value that is defined as contributing to a booked place,

this class will recalculate the number of ‘Booked Places’ based on the number of current Study Registrations.

Use case

This automates the calculation of how many users have confirmed their registration to a Study Offering.

For example (by default), if a Study Registration's status is ‘Confirmed’, this class will rollup and increase the ‘Booked Places’ field on the Study Offering by +1.

Similarly, if the Study Registration's status is changed from ‘Confirmed’ to a non-confirmed one, this class will decrease the Study Offering's ‘Booked Places’ field by -1. 

As of v3.18.5, this will also retrigger the calculation if the Study Registration is changed between two different types of rollup status.

For example, when a Study Registration is changed from ‘Waitlisted’ to ‘Confirmed’, both the ‘Waitlisted Places’ and ‘Booked Places’ will be recalculated accordingly.
