Hi All,

During our FHIR module resource update operations, we encounter some issues with updating the resources through REST. I looked at save methods of person and patient and saw they are doing saveOrUpdate in DAO layer. In DAO layer, it's checking whether id is exist for resource and do creation or update.

How REST module handle resource update requests? Is it first get resource by uuid and then update the fields then save it? Or is it follow different approach?

Thanks,

Harsha

Hi Harsha,

Most of the resources extend some common base classes, so you can see the typical behavior in DelegatingCrudResource.update() here:

https://github.com/openmrs/openmrs-module-webservices.rest/blob/master/omod-common/src/main/java/org/openmrs/module/webservices/rest/web/resource/impl/DelegatingCrudResource.java#L111

Particularly, yes it does:

T delegate = getByUniqueId(uuid);
...
delegate = save(delegate);
