In order keep configuration simple, please perform the following steps in Salesforce Classic (Booker25 is Lightning-Ready, you may afterwards use the app in Salesforce Lightning as you please) |
Use the following procedure to define custom price calculations on resources and services.
1. Create your custom price calculator class
Create a class that implements the interface B25.Util_PluginManager.ReservationPrice. Implementing that interface means the class must have a method with the following signature:
void
...
calculate(B25.Util_PluginManager.ReservationPriceData)
This method will be called whenever a reservation is saved, or whenever the reservation form gets rerendered. You can control when the reservation form gets rerendered, more on that in a bit. The B25.Util_PluginManager.ReservationPriceData object that gets passed along to the calculate method has two properties that will help you to make your own price calculation.
| Name | Type | Purpose |
|---|---|---|
reservation | B25__Reservation__c | Contains the service costs as shown on the reservation form when you have the setting 'Services have a price' enabled. [link to other doc page] Go here for more information about configuring Booker25's system settings. |
| serviceCosts | Decimal | Contains the reservation as it is at the moment the calculate method is called. It will have all the fields populated that are visible on the reservation form. |
In the calculate method you will be able to set any fields on the reservation property record, such as the B25__Subtotal__c field, in order to control the final price of the reservation, or to start an approval process.
