from-json

Sometimes, it makes sense for you to store your data as a JSON object, that is based on the entity type. For example, when using the property names of the entity class as properties of your object. If you are looking for a way to create an entity from a JSON response, that you got from an OData service, you are probably looking for entity deserialization.

This would be the JSON representation of a business partner in the SAP Cloud SDK:

{
  "firstName": "Peter",
  "lastName": "Pan",
  "toBusinessPartnerAddress": [
    {
      "country": "Neverland"
    }
  ]
}

You can use this data to build an entity using the fromJson() method. The example below shows how you would create an instance of the business partner class using the fromJson() method.

import { businessPartnerService } from './generated/business-partner-service';

const { businessPartnerApi } = businessPartnerService();
const businessPartner = businessPartnerApi.entityBuilder().fromJson({
  firstName: 'Peter',
  lastName: 'Pan',
  toBusinessPartnerAddress: [
    {
      country: 'Neverland'
    }
  ]
});

If there are unknown fields present in the JSON object, they will be treated as custom fields.
