Using Flask, REST API, and IAM with InterSystems IRIS

Part 2 – Flask App

Flask is a web development microframework written in Python. It is known for being simple, flexible, and enabling rapid application development.

Installing Flask is very simple. Once you have python installed correctly on your operating system, we need to install the flask library with the pip command. For REST API consumption, it is advisable to use the requests library. The following link provides a guide to installing flask: https://flask.palletsprojects.com/en/stable/installation/

Very similar question posed here: https://community.intersystems.com/node/467496, but I am missing a piece of this:

How do I correctly call a EnsLib.HL7.MsgRouter.RoutingEngine class from the BPL?I can successfully call the BPL from the EnsLib.HL7.Service.TCPService, and I have the BPL created to delay then call the rule. And I set the context and the result location.

Can someone help me understand what type of user error (?) is going on here please?

Recently, I replaced my old laptop with a new one and had to migrate all my data. I was looking for a guide but couldn’t find anything that explained in detail how to migrate server connections from InterSystems Studio and Visual Studio Code from one PC to another. Simply reinstalling the tools is not enough, and migrating all the connections manually seemed like a waste of time. In the end, I managed to solve the problem, and this article explains how.

The new version of InterSystems Testing Manager which I released last week brings @Timothy Leavitt's cool
Test Coverage Tool to VS Code, and is my entry for the 2025 Developer Tools contest.

Here's a teaser screenshot showing how the unit tests of the IPM project don't yet cover a feature that apparently allows an IPM repository to override its sort order.

Hi all,

I’m working on a data transformation in IRIS where I need to calculate the difference in hours between two timestamps stored as %TimeStamp.

Example:

Set startTime = "2024-07-12 08:30:00"
Set endTime = "2024-07-12 15:15:00"

I’d like to calculate the number of hours (with decimals, like 6.75) between them. What's the recommended way to do this in ObjectScript? I’ve seen examples using $ZDATETIME, but I’m not sure if that’s the cleanest approach.

IRIS supports CCDA and FHIR transformations out-of-the-box, yet the ability to access and view those features requires considerable setup time and product knowledge. The IRIS Interop DevTools application was designed to bridge that gap, allowing implementers to immediately jump in and view the built-in transformation capabilities of the product.

In addition to the IRIS XML, XPath, and CCDA Transformation environment, the Interop DevTools package now provides:

WSDL for a CDC vendor was provided with a URL using a custom socket (non 443). Everything generated fine, but when making calls to their https:// URL that has their custom port in the URL - no response comes back. The assumption is, their server isn't even processing the request, as Postman does using the custom https://path.to.server:NNNN port in the URL.

Hi everyone,


I'm currently testing out IRIS 2024.3 for a new project, and it's been running smooth for the most part. However, I noticed that when running some heavier analytical queries, the memory usage spikes more than I expected, even when result sets aren’t that large.

I’ve gone through the basics (buffer sizes, query plans, etc.), but I’m wondering if there are any new tweaks or recommended settings in 2024.3 specifically for managing memory better during these peak loads.

Anyone else run into something similar or have tips to fine-tune this?

My IRIS instance is connected to a Postgres database using SQL Gateway and linked tables.
One of these tables is projected to the Patient class. I want to select a record from this table by ID and convert it to a FHIR resource using the %ExistsId and %OpenId methods.
I noticed that if I call these two methods from the console, the record is always found.

Hi Community,

Sometimes you may need to merge multiple accounts or simply update the email address you use across the different portals in the InterSystems Developer Ecosystem. Since each portal works a little differently, here’s a guide to help you through the process.

Change your email

If you’d like to use a different email (for example, use a work email instead of a personal one, or vice versa), here’s how to update it across the portals:

1. Update your email in InterSystems SSO. To do this:

  • follow the prompts on screen to change your email

I'm creating a Business Process that:

  1. Transforms one object into another using DTL
  2. Sends this object to an operation
  3. Transform the object obtained in first point into another one using DTL
  4. Sends the second object to an operation

The Business Process is created with BPL, and objects are stored in BP context. When I execute this Process, in the 3rd point the object obtained in first transformation doesn't exist. It's empty.

I have tried to make transformation before making CALL's, I mean:

Hello Developers,

I have MacBook Pro M3 and I'm new to the IRIS for Health setup / installation with all pre-requisite / requirements so someone could please help me with detailed instructions on how to setup IRIS for Health (HL7 & FHIR) from scratch along with SQL Server? I have Windows 11 installed in parallel desktop if that's required and complete installation / setup is not possible on MacBook.

Thank you in advance.

Hi

Is there a way to remote connect to IRIS terminal from my local machine?

I can remote connect to Studio & SMP from my locally windows installed IRIS cube to another IRIS installation in a Linux server, but not the case when trying to connect to the Terminal, is there a way to do so? I'm currently using ssh client but that one times out quickly

Thanks
