CAP / CDS Nested JSON structures

[former_member743968]

Does CAP / CDS allow us to expose 1 to 1 nested JSON objects? I see that defining a to many relationship creates an object array however, I am trying to expose nested objects without created 1 to n relationship.

1. @sap/cds: "5.8.0
2. cds2types: "^2.7.2"
3. cds-swagger-ui-express: "^0.3.0"

To many scenerio:

To one scenerio causes for the entire entity to flatten on itself. I need to be able to control how whether included structures are flattened or nested.

desired structure:

{
   "ShipRequest": {
      "Pickup":{
         "Carrier":"string",
         ...
      }
   }
}<br>

After some trial and error, I found a solution for my use case shown below. I'm very interested if there are other suggetions on how to accomplish this without declaring types as entities.

cds definition:

swagger-ui
