Totals Calculation

To implement this feature it is necessary to inherit from the ability to List Totals, which is done via the triple:

MyEntity is a Ability.ListTotals.

This will inherit a view 'TotalAttributes' which will be added any field(s) that need to be totaled.


For this example we will use the entity OrderDetail.

The inheritance would be defined like this:

OrderProcessing.OrderDetail is a ENT Ability.ListTotals.

After inheriting from ListTotals observer that the entity OrderDetail has a new view named Total Attributes.

In the Total Attribute view choose a field(s) found on the grid to calculate its total. In this example we will use two fields from the grid: Quantity and Derived Line Total.

Generate Changes.

For the test Model there is an OrderProcessingbuildObjects list object that contains all the template generation functions for all the entities of the application:

After generating the OrderProcessingbuildObjects list generate the ApplicationServerObject which is a list of all the server objects required for the HSYNC application:
