GSoC’ 21 @OpenMRS- Week 6

Project: Support for Extended Operations on FHIR

Week 6 Experience:

Week 6 proved to be a little challenging. We started working on phase 2 of the project which required implementing the $everything operation on Patients. The point which proved a little difficult for me to comprehend was how to prevent pagination since there should be no pagination done for $everything operation unless specified using the _count param. Moreover, the SearchQueryBundleProvider returned response in which the count of resources from_include and _revinclude were not included in the bundle total, so we had to prevent that from happening as well for this operation. But with a lot of help from my mentor, we were able to figure it out. We fetched the response using getAllResources() and packaged it SimpleBundleProvider with the preferred page size as the total size of the list.

Tickets I worked on:

FM2–409 : Corrected the bundle type in $lastn operations(Code review)

FM2–411: Support for instance level $everything operation on Patients in R4(Code review)

Plans for next week:

After the PR for FM2–411, we will add the implementation in R3 and add integration tests for R3 and R4.
