Hello everyone! Don't miss the Developer Community Post Digest for June 2022.

Hey Developers! Here is a digest of new solutions and applications submitted to the InterSystems Open Exchange in June 2022.

The InterSystems IRIS has excellent support for encryption, decryption and hashing operations. Inside the class %SYSTEM.Encryption (https://docs.intersystems.com/iris20212/csp/documatic/%25CSP.Documatic…) there are class methods for the main algorithms on the market.

IRIS Algorithms and Encrypt/Decrypt types

As you can see, the operations are based on keys and include 3 options:

• Symmetric Keys: the parts running encrypt and decrypt operations share the same secret key.

Hi Everyone,

              I am a very new to IRIS Object Script Development. There is a  usecase where I have to execute a .sh file from the object script. I am looking for examples for that, but what I find is the ways to execute the shell commands. Can you please point me to some examples executing a .sh file. Thanks in Advance

Hi developers. I often miss the ZPM program on a clean system. Nothing complicated? Take and install. And in one line? Especially in a docker container. There is a solution. I'm very happy with it;) Maybe the line can be shortened?

set $namespace="%SYS", name="DefaultSSL" do:'##class(Security.SSLConfigs).Exists(name) ##class(Security.SSLConfigs).Create(name) set url="https://pm.community.intersystems.com/packages/zpm/latest/installer" Do ##class(%Net.URLParser).Parse(url,.comp) set ht = ##class(%Net.HttpRequest).%New(), ht.Server = comp("host"), ht.Port = 443, ht.Https=1, ht.

If one of your packages on OEX receives a review you get notified by OEX only own YOUR package.   
The rating reflects the experience of the reviewer with the status found at the time of review.   
It is kind of a snapshot and might have changed meanwhile.   
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on Github when I found a problem I could fix.    
Some were accepted and merged, and some were just ignored.     
So if you did a major change and expect a changed review just let me know.

Developer Preview releases are now available for the 2022.2 version of InterSystems IRIS, IRIS for Health, and HealthShare Health Connect.

 This is the first in a series of releases that are part of the developer preview program. Future preview releases are expected to be updated biweekly and we will add features as they are ready.  This program allows us to get feedback on capabilities and enhancements as they're available.  You'll see below a list of enhancements that are targeted for 2022.2.  Some these are not included in the first developer preview.  Look for those over the coming weeks.

We recently migrated to IRIS. Before, the CACHE.EXE executable could be invoked from a batch file directly : 

C:\InterSystems\Cache\bin\cache.exe -s C:\InterSystems\Cache\mgr -U %SYS

This will display the following in console : 

Node: DESKTOP-8H4B321, Instance: CACHE

USER>

Additionally, the pipe instruction can be used to redirect some commands directly

echo write 50 | C:\InterSystems\Cache\bin\cache.exe -s C:\InterSystems\Cache\mgr -U %SYS

I am looking for the same thing in IRIS.

@Ming Zhou asked a great question in https://community.intersystems.com/post/how-get-all-properties-defined-… and the answer sums up exactly why ObjectScript is my favorite.

When I'm first describing ObjectScript or IRIS to someone I always explain that you can write a class, compile it, get a table, and work with your data from an object or relational perspective - whichever is most natural.

I have a table with a Varchar(max) column that I have created via the HealthShare SQL portal, and I see that in it's underlying class that column corresponds to a  %Stream.GlobalCharacter

When I try to do a text search on that column (referenced as cd.Code in the example below) I get an error

select * 
from DevTools_CodeAnalysis_tables.Code cd
inner join DevTools_CodeAnalysis_tables.MethodData mtd
on charindex( mtd.qualifiedRef,  cd.Code) > 0

It produces the error

 Scalar function CHARINDEX (arg2) not supported for stream fields

How do I search it?
 

Hi There,

I'm fairly new to ObjectScript/Ensemble and I'm sure I may be fundamentally misunderstanding how the %JSONImport/%JSONExport and XDATA mapping work and I was hoping you good folks could help me out.  I'm essentially trying to create an object that I can use to translate from one JSON schema to another. 

First my class:

Class SERVICESVCPKG.Model.AthenaAppointment Extends (%Persistent, %DynamicAbstractObject, %JSON.

Is it possible to mirror the same database on Iris and an older Ensemble instance?

Specifically to try a zero downtime upgrade

I am trying to pass %request.Data from my rest dispatch class to a production so that I can use it in by business operation.  I have created a message that has a property:

Property urlParameters As %String [multidimensional];

to get the data to the production. I am new to intersystems and multidimensional arrays/globals

dispatch class:

Kill parameters
Merge parameters = %request.Data
Set genericRequest = ##class(Core.API.V1.Msg.GenericRequest).%New()
Set genericRequest.

I'm hoping someone here has some tips. I'm trying to filter by d/t in a routing rule. Basically if before a specific d/t, send to one feed. If after, send to another. The d/t time is in a yyyymmddhhmmss format. I've tried a couple things but can't get it to work as expected. Any tips to accomplish this would be appreciated.

Hi All! We have recently updated the Exploring Healthcare Analytics with InterSystems exercise to a new version. Originally from a 2021 Virtual Summit experience lab, this exercise now focuses more specifically on using InterSystems IRIS Adaptive Analytics with InterSystems IRIS for Health. It features a new and improved data model and exercise to explore. Feel free to give it a try!

Hi Guys,

I'm getting the below TLS error in SSL_connect(), SSL_ERROR_SYSCALL, I've treid mulitple SSL/TLS configuration and still get the same error, so should I be asking the client that I'm trying to connect if there a specific certificate or configuration!?

Thanks

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD

In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.

In the second article, we covered GitLab Workflow - a complete software life cycle process and Continuous Delivery.

I this article we'll discuss:

• GitLab installation and configuration
• Connecting your environments to GitLab

I want to call a method which is in %SYS namespace : 

set NS = $NAMESPACE
ZN "%SYS"
do ##class(Config.MapGlobals).Delete(...)
ZN NS

In reality code is even more complex (eg: need a try catch block to make sure namespace is switched back even if there is some error).
Is it possible to do this without changing current namespace ?
For example (does not work) :

do ##class(%SYS.Config.MapGlobals).Delete(...)

Hello,

I am wondering if anyone can help me with an issue we are facing. We are trying to add a parent-child relationship between 2 tables in the database that already contain data. We are able to add the new relationship property to the required data classes, and set the desired cardinality. We have also included code that will add the relationship using the Insert() method to new data that comes in.

The problem we have is how do we add the relationship to data that already exists in the database?

Couldn't see this on the community, not sure why...

Hi, I tried the following exercise from the IRIS documentation. I updated the username, password and IP address, but receiving this error;

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. --->

I can use the same credentials and IP address to connect ok via VSCode to my local IRIS...

Any pointers much appreciated.

Has anyone here been successfully populating a %Persistent object from calling %LoadFromMemory() with a temp. global?

I have tried using Sample.Person in the SAMPLES namespace. It worked EXCEPT that I have no way to set the id into that Sample.Person objec.

SAMPLES>Merge array(1) = ^Sample.PersonD(1)
 
SAMPLES>Set obj = ##class(Sample.Person).%LoadFromMemory(1,.array)
 
SAMPLES>zw obj
obj=1@Sample.Person  ; <OREF>
+----------------- general information ---------------
|      oref value: 1
|      class name: Sample.

I think it's a known fact that Populate Utility has very limited functionality. It supports only one language and one country. The list of possible values does not have so many options. 

There is a kind of tool that now can help with it, named Faker. It has implementations in different languages, including Python. Since IRIS has now had the Embedded Python feature, Python faker can be implemented in IRIS.

Hi All,

I am preparing for InterSystems IRIS Core Solutions Developer Specialist Certification. I have completed the desired syllabus. Does anyone have any questions dumps. I have already completed the practice paper on Intersystems website.

This formation, accessible on my GitHub, will cover, in half a hour, how to read and write in csv and txt files, insert and get inside the IRIS database and a distant database using Postgres or how to use a FLASK API, all of that using the Interoperability framework using ONLY Python following the PEP8 convention.

This formation can mostly be done using copy paste and will guide you through everystep before challenging you with a global exercise.
We are available to answer any question or doubt in the comment of that post, on teams or even by mail at lucas.enard@intersystems.com .

Suppose you have developed your own web app with InterSystems technologies stack and now want to perform a captcha validation on the client side in order to determine whether or not the user is human and make it safer. There are some modern frameworks to address the captcha issue, however most part of them needs internet access to generate codes and sometimes are complex to implement. Take this as basic example considering that image recognition has gotten too good. That's why you nowadays you tend to see more pattern recognition captchas than mere reading ones. (I.e.
