Adding Disease Variants to a SORMAS Server

Introduction

This guide explains how to add a new disease variant to SORMAS.

Preparation of the data

First step is to retrieve the identifiers of the diseases. An exhaustive list can be found inside the enum de.symeda.sormas.api.Disease.

Persist the data

1. Get into pgAdmin or into the postgreSQL shell to be able to execute the following queries into the PostgreSQL database.
2. Replace the variable {{ DISEASE ID }} in the following query with the Disease ID taken from the Java enum indicated in step I.
3. Replace the variable {{ VARIANT NAME }} in the following query with the name of the disease variant.
4. Replace the [...] by all other rows you need to add.
5. Execute the generated query.
6. Let's verify that the table diseasevariant is well completed with your data.

Here is the SQL query to execute:

INSERT INTO diseasevariant (id, uuid, creationdate, changedate, disease, name)
VALUES
  (nextval('entity_seq'), gen_random_uuid(), now(), now(), '{{ DISEASE ID }}', '{{ VARIANT NAME }}'),
  [...];

Here is an example of the query with sample data:

INSERT INTO diseasevariant (id, uuid, creationdate, changedate, disease, name)
VALUES
  (nextval('entity_seq'), gen_random_uuid(), now(), now(), 'YELLOW_FEVER', 'Yellow Fever Variant 1'),
  (nextval('entity_seq'), gen_random_uuid(), now(), now(), 'YELLOW_FEVER', 'Yellow Fever Variant 2'),
  (nextval('entity_seq'), gen_random_uuid(), now(), now(), 'DENGUE', 'Dengue Variant 1'),
  (nextval('entity_seq'), gen_random_uuid(), now(), now(), 'MALARIA', 'Malaria Variant 1'),
  (nextval('entity_seq'), gen_random_uuid(), now(), now(), 'MALARIA', 'Malaria Variant 2');

In case PostgreSQL complains about unknown function gen_random_uuid(), it means the pgcrypto extension is not enabled. To enable it, please login with a superadmin account on your PostgreSQL server and execute the following query:

create extension pgcrypto;

That's it. The forms in the web application and Android app will now have their Disease variant fields filled.
