Hi community,

This article to give a description of my small library JSON Filter.

Why JSON Filter?

Search, sort data are common operations.

But … How to do this with JSON data?

You can use a %DocDB, It’s a good way for storing JSON and index the main properties.

However, JSON document is very flexible. It isn’t always possible (and not recommended) to index each properties to process the wished queries. A manual processing on a data subset is may be required.

In my opinion, this is not a funny part of the job. It’s a repetitive code with many loops etc.

Hi Developers,

New to machine learning? Watch this video on InterSystems Developers YouTube to understand the basic concepts of machine learning and how it provides value in applications around the world today: 

⏯ What is Machine Learning?

During runtime I build an object which is essentially a wrapper over in-memory table:

I want to use this object as a part of INSERT or UPDATE queries, based on a value of some column (the main use case one of the columns is an ID value)

What's the best way to expose the object to SQL?

I have complete control over object class, so if I need  to add something (or even change runtime internals), it's no

Hi everyone,

The project IRIS History Monitor received an update, using ZPM and the built-in REST API /api/monitor/metrics.

Hi Developers!

As you know in the second contest we introduced technology bonuses. Learn more.

You can see what app got what bonuses in the Technology Bonuses menu:

And here I want to share with you which apps got the bonus. Here we go!

Hey Developers,

We're pleased to invite you to the "Best practices of in-platform AI/ML" webinar by InterSystems on April 28th at 11:00 EST/17:00 CET.

Hi Community,

We're pleased to invite you to join the upcoming InterSystems IRIS 2020.1 Tech Talk: API-First Development on May 5 at 10:00 AM EDT!

In this week's InterSystems IRIS 2020.1 Tech Talk, we'll discuss API-first development and how InterSystems is embracing this industry trend with our API Manager, and specifically with our FHIR offerings. First, we'll talk about InterSystems API Manager. This tool controls your web-based API traffic in a single location. You can throttle throughput, configure payload sizes and whitelist/blacklist IPs, among many other features.

FHIR stands for Fast Healthcare Interoperability Resources. Release 4 brings this HL7 standard to maturity, and the FHIR R4 support in InterSystems IRIS for HealthTM is big. You'll learn how to work with FHIR data in InterSystems IRIS, and see our developer portal in action, where you can access FHIR resources using the OpenAPI specification.

i've noticed a strange bug in the 'problem highlighting' of VSCODE and i wasn't sure if this is a problem with the internal library definitions of iris, or with the plug-in itself.

The first line is the correct macro call, but the second one is the one throwing the error. (preprocess vs prepOrocess)

How is this syntax checker's list of strings compiled?

Hi Team,

I am creating an API POST method to which the Web Requests will come. I want to identify that from which device (Mobile, Tablet, Laptop, Ipad etc) the request came. 

Let me know if you need more details from me regarding the question.

Hi Developers!

Want to participate again in the competition of creating open-source solutions using InterSystems IRIS Data Platform? 

Then we're pleased to announce the second InterSystems IRIS Online Programming Contest!

And the topic for this contest is InterSystems IRIS with REST API.

The contest will again last three weeks: April 13-May 3, 2020. 

Also, please join the InterSystems Contests Discord Channel to chat about contest and technology.

I enjoy the challenge of being in a contest. Currently I participate in InterSystems IRIS with REST API Programming Contest. My idea for this contest was to create an app to help me keep track of tasks for my Status Reports. I started with the template provided by Evgeny Shvarov. I created a persistent class for Tasks and a REST Dispatch class. I defined my URL map and I even figured out how to test my REST app using Postman. I felt proud of myself for a little while.

When I describe InterSystems IRIS to more technically-minded people, I always start with how it is a multimodel DBMS at its core.

In my opinion that is its main advantage (on the DBMS side). And the data is stored only once. You just choose the access API you want to use.

• You want some sort of summary for your data? Use SQL!
• Do you want to work extensively with one record? Use objects!
• Want to access or set one value and you know the key? Use globals!

Hi Developers!

We are having a series of InterSystems IRIS Online Programming contests this year!

This announcement is for current and all future online contests. 

Below you'll find the judgment rules for the IRIS Contest.

Hi Developers!

Today we launched the second programming contest on InterSystems IRIS, the landing.

The topic is the REST API.

And we introduced a few technology bonuses.

Here I want to provide details on what application eligible, what are the technology bonuses and how to collect all of them.

Here we go!

Simple problem:

1. I leave a long-running command in terminal
2. Switch to another task(s)
3. Remember that I need to check on my command after a few hours

Is there any way to force terminal to the foreground after current command ends?

This is Windows with cterm/iristerm although Putty/Kitty solution would also be nice.

Hi,

Do you have any experience in inserting a panda dataframe into SQL IRIS Table? The dataframe.to_sql method uses sqlalchemy and it seems no dialect is available for IRIS.

thanks, Blaise

One of the things I want from VSCode is to have a familiar Studio look.

Thankfully VSCode is easily customizable so you can choose any color for any element.

Here's what I got so far:

To get the same look add to your settings.json:

"workbench.colorTheme": "Default Light+",
"editor.tokenColorCustomizations":{
    "textMateRules": [
        {
            "scope": "entity.other.attribute-name.objectscript_class",
            "settings": {
                "foreground": "#000000"
            }
        },
        {
            "scope": "string.quoted.double.

Hi, i have installed Prometheus as solution to monitor IAM, Iris & Docker, someone have experience using something like : 

https://github.com/Lusitaniae/apache_exporter

this use mod_status, but i'm not sure if possible activate this on containers, ideas ?

I want monitor WebGateways on Prometheus, finally have a full Grafana based monitor for all systems.

Hi!

I believe the simplest is (to work with csv delimited by ";"):

set file = ##class(%File).%New( "data.csv" )
    set sc = file.Open( "R" ) 
    if $$$ISERR(sc) quit    ; or do smth

    while 'file.AtEnd {
        set str=file.ReadLine() 
        for i=1:1:$length( str, ";" ) {
            set id=$piece( str, ";" ,i ) 
            write !, id  // or do smth
        }
    }
    do file.Close()

Possible options:

different variants of error handling with sc code.

Embrace while loop into try/catch block.

And what's yours?

What is an index, anyway?

Picture the last time you went to a library. Typically they have books sorted by subject matter (and then author and title), and each shelf has an end-plate with a code describing the subject of its books. If you wanted to collect books of a certain subject, instead of walking across every aisle and reading the inside cover of every book, you could head straight for the bookshelf labelled with your desired subject matter and choose your books.

Can someone help me?

I'm triggering a Rest Services, my JSON is a String variable(Request.JSON), when I pass it on EntityBody.Write, WS returns me the 403 error.
When I pass Obj = {} it responds by saying that no Data has been sent.
So, my problem is to set the "Obj" with the String variable, I should convert it, correct? But how do I do this? My JSON is all in this variable.

            Dados.Authorization = pBearer _ Request.Token,
            Dados.ContentType = "application/json"
