Hi,

I'm having a problem with %JSON.Adaptor and "list of" binding.

For exemple, this class with a property "oazisCode As list of %String".

Class User.ADGroup Extends (%Persistent, %JSON.Adaptor)

{
/// Code interne
Property code As %String;

/// Libellé
Property text As %String(MAXLEN = "");

Property oazisCode As list Of %String;

}

The first time call to %JSONImport works properly

s r = ##class(User.ADGroup).%New()
s json = {"code": "123", "text":"456", "oazisCode": ["1","2"]}
d r.%JSONImport(json)
w r.oazisCode.

Hello All,

No matter what I try in Business Process Logic (BPL), I am unable to calculate the patient's age in days or years.

Has anyone ever built logic in a Business Process (BPL) to calculate a person's age in days?

Thank you!

Why do these clauses affect SQL performance?

select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite select top 10 ID from some_table where row_status in ('I','U') order by ID - the same select ID from some_table where row_status in ('I','U') order by ID - is fast

Actually there are no rows in the table having row_status 'I' or 'U'.

I want to implement isc-rest in my new project iris-budget/module.xml at master · oliverwilms/iris-budget

I get this error:

#8 11.30 Building dependency graph...
#8 12.69 ERROR! Could not find satisfactory version of isc.rest in any repositories. Required by: iris-budget 0.0.1: ^2.0.0
#8 ERROR: process "/bin/sh -c iris start IRIS && \tiris session IRIS < iris.script &&     ([ $TESTS -eq 0 ] || iris session iris -U $NAMESPACE \"##class(%ZPM.PackageManager).Shell(\\\"test $MODULE -v -only\\\",1,1)\") &&     iris stop IRIS quietly" did not complete successfully: exit code: 1
 

In this article, I aim to demonstrate a couple of methods for easily adding validation to REST APIs on InterSystems IRIS Data Platform. I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!

Recent versions of IRIS come with Lite Terminal available from VSCode. It's a websocket server, with JSON messaging. Here's how to connect to it from Python:

import websocket
import argparse
import requests
import json


defterminal(host, port, namespace, username, password, command, secure):
    session = requests.Session()
    r = session.get(f"http{"s"if secure else""}://{host}:{port}/api/atelier/", auth=(username, password))
    cookies = session.cookies.get_dict()
    ws = websocket.WebSocket()
    ws.

Hey everyone,

I'm just seeking some guidance and confirmation on what I'm doing for my production health monitoring.

We utilize Grafana to have reporting/monitoring dashboards and I have made a REST API to query the health of our productions. I believe I have everything figured out except for one thing that I'm uncertain about and that is the Production Item Color indicators:

Is there an easy way of being able to figure out the status of an item with the legend above? Ideally, I'd like to have this data in my JSON response.

Hey everyone.

I have a web service which is receiving XML as a stream, and I'm intending to then correlate the stream into an object. Unfortunately I am hitting a road block where the sender places a large chunk of the XML within a cdata block which is then causing the correlate of %XML.Reader to not work.

Hello everyone. I'm currently working on how to implement a solution that makes it possible to include within the response of a BusinessOperation the "RetryCount" for each message.
For Example, we have this message that was retried twice:

This is an HL7.message going through a specific business operation, we did not create a custom one: we used the default implementation EnsLib.HL7.Operation.TCPOperation. This operation should automatically handle retries (infinetely waiting on a response).

Hi,
I need to create a bundle of synthetic data in order to populate FHIR servers (not mine).

Can I use a predefined ids, or is it possible the one of the servers will not allow using my IDs and replace them with it's automatic numbering?

We're pleased to invite you to the upcoming webinar in Hebrew:

👉 Debugging InterSystems IRIS & Health Connect: From VS Code Breakpoints to Interoperability Traces 👈

📅 Date & time: Feb 18th, 3:00 PM IDT

When production issues arise, speed and precision matter. This webinar is a practical, tool-driven walkthrough of debugging in InterSystems IRIS (including IRIS for Health) and Health Connect - starting with code-level debugging in VS Code and extending into platform and interoperability diagnostics. We will cover core logging as well as tracing techniques.

Hello Team,

I am trying to duplicate the production flow in the Ensemble 2018 but after doing all the steps (like copying same class file, adapter file, process class file) as production, still the flow is not working. The error is that it is not reaching the operation (which is supposed to store the data), it gets stuck in the processes. Additionally, I am also trying to add a logic where in OUL message if the value of code 20061 > 30mg, it should automatically send another order back to service (OML).

Hello, I am trying to get some fields from HL7 message and create a file using BPL.  The values I need are in a repeating segment (AIG).  Even in the repeating segment, I just want the iteration that has a certain field (AIG:3 populated).  With the help of documentation and community posts, I was able to create the BPL to loop through all of AIG and create the file.  But when I try to narrow the results even further (AIG:3 present), the process gets stuck.  I am not sure I am missing anything or have anything incorrectly set up.

Hi,

I want to consume an API that provides HL7 messages. To achieve this, I have thought of the following workflow:

I have created a business service that periodically triggers a business process. The trigger request is forwarded to a business operation. There, a %Net.HttpRequest is assembled from scratch and then sent to the API endpoint. The corresponding HttpResponse then contains several HL7 messages encoded in UTF-8 in the message body. To further process the HL7 messages, the operation sends the HttpResponse back to the business process as EnsLib.HTTP.GenericMessage.

The 2025.1.3 maintenance releases of InterSystems IRIS^® data platform, InterSystems IRIS^® for Health^TM, and HealthShare^® Health Connect are now Generally Available (GA).
