Dear Fellow Cache Gurus: I would like to know if there is either any built-in Cache Date/Time function or an easy way to include a timezone abbreviation such as EST, PST, MST, etc... within the Cache Date/Time formats.

I read through the Cache Documentation but could not find anything to achieve this.

So if I do the following command: $ZDateTime($H,1,4,,,4,,,,,"InvalidDate"), then I get an output like this: 02/27/2025 11:10AM

But I am looking for the output to be formatted like this: 02/27/2025 11:10AM EST

I am building a web application that uses JWT for authentication. I would like to pass the token in cookies instead of the Authorization header.
Is there a way to intercept the request and check the token from the cookies instead of the header? I tried overriding the OnPreDispatch() method and adding it to my dispatch class, but it seems like it never gets executed, as the response returns "Unauthorized" before reaching it.

Hi, Community!

Are you working with clinical data in a research setting? See how InterSystems OMOP streamlines data integration and analysis.

In the world of APIs, REST is very extended. But what happens when you need more flexibility in your data-fetching strategies? For instance letting the client to choose what fields is going to receive. Enter GraphQL, a query language for your APIs that provides a flexible alternative to REST.

In this post, we will:

  • Compare REST and GraphQL.
  • Dive into the basics of GraphQL: Queries, Mutations, and HTTP.
  • Build a simple GraphQL server implementation using Graphene, SQLAlchemy, and Flask over data in InterSystems IRIS.
  • Explore how to deploy your GraphQL server as a WSGI application in IRIS.

Input Redirection

Hello, I try to develop a REST interface where I need to interact with legacy MUMPS routines. How can I pass in input to a Read without modifying the legacy code?

I think in linux I can execute command < inputfile to read from file, but how does it work in ObjectScript?

The Case for IRIS and JavaScript

Introduction

My guess is that most IRIS developers create their applications using its native ObjectScript language or, if using an external language, then most likely using either Java, Python or perhaps C++.

I suspect that only a minority have considered using JavaScript as their language of choice, which, if true, is a great shame, because, In my opinion and experience, JavaScript is the closest equivalent to ObjectScript in terms of its ability to integrate with the IRIS's underlying multi-dimensional database.

I'm working on FHIR project and using this code to convert an incoming request to FHIR

Method OnRequest(request As HS.FHIRServer.Interop.Request, Output response As HS.FHIRServer.Interop.Response) As %Status

{

#dim tSC As %Status = $$$OK

Try {

// Process incoming request

set stream = ##class(HS.SDA3.QuickStream).%OpenId(request.QuickStreamId)

set bundle = ##class(HS.FHIR.DTL.vR4.Model.Resource.Bundle).FromJSON(stream,"vR4")

Hello everyone!

I have set up an EnsLib.REST.GenericService with an EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process.

I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.

As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do :

Hi Community,

Watch this short exercise in writing basic code snippets in InterSystems ObjectScript using Copilot in VSCode and the GPT-4.0 engine. This screencast covers "Hello, World," global manipulation, class creation, and building a simple REST API application.

So, you checked your server and saw that IRISTEMP is growing too much. There's no need to panic. Let’s investigate the issue before your storage runs out.

Step 1: Confirm the IRISTEMP Growth Issue

Before assuming IRISTEMP is the problem, let’s check its actual size.

Check the Free Space

Run the following command in the IRIS terminal:

%SYS>do ^%FREECNT

When prompted, enter:

While upgrading old Ensemble and Health Connect applications to V 2024.1 we are installing many webgateways since the private webserver is deprecated.

Configuring the "Default Parameters" we can determine the "Event Log Rotation Size" but not the count of preserved logfiles. So even if the webgateway cuts the logs in pieces they could fill up the disk space entirely for there seems to be no cleanup-job for old logfiles.

What is the recommended way to deal with this situation?

Do I have to create a schduled job on OS-level?

Basic JSON Compare

Hi Dev Community

I thought i would share a little method I knocked together to traverse and compare 2 JSON objects for basic equivilance. I'm currently working on some data migration, and wanted a basic sanity check to validate that the JSON output is basically equivliant between the old and new, excluding a few things like timestamps.

It's a basic little recurvsive method, that will bubble up any differences over a nested structure. It's very low tech, as that's all I need it to do, but I thought it might be useful for others?
