Delete data

FHIR delete

You can delete single resource using DELETE FHIR API method. This method deletes the resource specified and create a history entry for the operation. The history entry created contains entire deleted resource.
Note that Aidbox does not enforce referential integrity for DELETE method.
Example.
Request:
DELETE /fhir/Patient/pt-1
Response:
meta:
lastUpdated: '2022-09-20T12:55:25.226619Z'
versionId: '5169631'
name:
- given:
- John
family: Smith
id: pt-2

Transactional Delete

If you need to delete multiple resources, use FHIR Transaction with multiple DELETE requests.
This operation groups multiple REST API operations in a transaction. If all DELETE operations are successful, the transaction with DELETE requests is equivalent to calling DELETE multiple times.

Delete resource history

If you need to delete resource history, you need to execute SQL manually.
Example:
DELETE * FROM Patient_history
WHERE id='pt-1'
Or you can make a REST endpoint from SQL query using AidboxQuery.
Example:
PUT /AidboxQuery/remove-patient-history
params:
id:
isRequired: true
type: string
format: '%s'
query: 'DELETE FROM Patient_history where id = {{params.id}}'
type: execute
And then run it with
GET /$query/remove-patient-history?id=pt-1

Delete all resources and history

You can use truncate PostgreSQL statement to delete everything from the specified table.
Example:
truncate Patient;
truncate Patient_history;
Similarly you can create an endpoint for this
PUT /AidboxQuery/truncate
query: 'TRUNCATE {{resourceType}}; TRUNCATE {{resourceType}}_history'
type: execute
And then run it with
GET /Patient?_query=truncate
Note that AidboxQuery with variable resourceType can only be called with _query parameter.

Delete resources in CI environment

In CI environments it is often desired to have same state at the beginning of each test suite. You can simply stop Aidbox, drop database, and start Aidbox again.
Use Aidbox project to set up fixtures. Note that you can use different Aidbox projects for each test suite (or different entrypoints).
