#InterSystems IRIS

Very simple, how to debug? The settings recommended in the docs don't work. I need a convenient way to keep track of what a function returns, like in other languages, by displaying it in the console.

It's well-known that Studio and probably VS Code have options to expand ObjectScript commands and functions to their full names (Ctrl-E and Ctrl-Shift-E in Studio), therefore some methods to accomplish this should exist. The question is: how to do it programmatically?

Hi! recently I have to apply api-key validation to a web app with a lot of endpoints and I'm going to tell you how I did it in a centralized way.

I'm going to explain you how we can apply in a generic way (or not) api-key validation to all the endpoints of our web app.

For this feature I take as a template the class Base.cls of this repository iris-rest-api-template

I modified a bit this class to be able to check api-key security. The idea is that in your features you copy this class in your projects and you extend it for your own implementations.

Hi Community,

In the first part, we describe all packages, used libraries and REST services.

Now, I would like to add some details about converter and validator services.

By default, OpenAPI-Suite sends an HTTP request to converter.swagger.io if the specification version is less than 3.0 and another HTTP request to validator.swagger.io to simplify the structure of the specification document.  

Although the usage of online utilities is convenient, in some cases it could be better to have our own instance of the converter and validator.  For example, if OpenAPI-Suite is provided on a server in an organisation for ObjectScript developers, it may be preferable to avoid requests to external services (privacy, avoid request rate limits). 

Just run: 

docker run -d -p 8085:8080 --name swagger-converter swaggerapi/swagger-converter:latest
docker run -d -p 8086:8080 --name swagger-validator-v2 swaggerapi/swagger-validator-v2:latest

I've been trying for a while now to get OS authentication working on IRIS running on Ubuntu 20.04 and subsequently 22.04. I have the following authentication methods enabled for %Service_Terminal:

• Operating System
• Password
• Operating System Delegated Authorization

And i have these options selected in Authentication/Web Session Options:

But when logging in via iris session <instancename> I am always prompted for a username and password. I am logged into the operating system with a username that matches my IRIS username, and the same configuration and login method works fine on Red Hat 8.5.

Hey community! 

It's time to elevate your unit tests to the next level with iris-TripleSlash new solo feature!

We are bring to the game Setup and Tear down events!
Just add description on class, with special tags like:

• beforeAll
• beforeOne
• afterAll
• afterOne

The tripleSlash will turn it to:

• OnBeforeAllTests
• OnBeforeOneTest
• OnAfterAllTests
• OnAfterOneTest

And that's not all! The new double dot abbreviation feature allows you to effortlessly call methods and simplify your code, i.e.:

///<example>/// Write ..TheAnswerForEverything()

Hi folks!

I'm playing with IRIS interoperability at the moment and it turned out that Data Transformation cannot be the element of production by itself.

It can be called either from data rule or from business process.

But why? 

What if I just want to change the message with the transformation and transfer the message somewhere else? Why the overhead with Rule or Business process?

Hi Developers!

Suppose you have a persistent class with data and you want to have a simple Angular UI for it to view the data and make CRUD operations.

Recently @Alberto Fuentes described how to build Angular UI for your InterSystems IRIS application using RESTForms2. 

In this article, I want to tell you how you can get a simple Angular UI to CRUD and view your InterSystems IRIS class data automatically in less than 5 minutes.

Let's go!

From where I can download the latest version of IRIS.  

Schematron is a rule-based validation language for making assertions about the presence or absence of certain patterns in XML documents. A schematron refers to a collection of one or more rules containing tests. Schematrons are written in a form of XML, making them relatively easy for everyone, even non-programmers, to inspect, understand, and write

Sessions and specifically %session are paramount to our application to login users to the application (the Web Gateway user logs into the server and then users login to the application).  

When using /api/mgmnt/v2 to implement a spec first approach to REST API development, I am unclear how I can utilize sessions (i.e. %session) to work with our existing model (and I'm sure there are indeed better ways to do this, but we are just baby stepping right now). Much of the documentation say to make sure UseSession=1 in the dispatch class is set, which I've accomplished.

I use the following code (which is a simplified version of what happen on a server) :

tstartfor1

Test.Test is a persistent class that inherit from %Persistent :

I think delocks are needed because of the transaction, to maintain data consistency, but why exactly are they needed here ?

Is there some options that can be used to avoid the delocks ? (even if data consistency is lost).

Hi Community,
In this article I will demonstrate below steps to add Interactive map and visualize geographic data to web application:

• Step1 : Install Application
• Step2 : Create CSP Page
• Step3 : Extend dc.IrisGeoMap.Folium class
• Step4 : Invoke DrawGeoDetails() Method

So Let us start.
 

Step1 : Install Application

First of all we need to install iris-geo-map application by using ZPM

zpm "install iris-geo-map"

Recently i've been using Restforms2 to create a CRUD API for a project. But it lacks some advanced functionality that we need, so we have created a production with a REST WS which handles those advanced methods. That works great but there's a drawback, it does not have authentication. 
I would want to use the same authentication method as Restforms2 which is a basic auth using IRIS users and passwords. 
Searching for this, i have found a similar topic. It uses $SYSTEM.Security.Login(user, pass) in a similar manner to create a token.

Does anyone happen to have a sample Configuration (CPF) Merge file that includes Action parameters setting up authentication methods (e.g. Password, Kerberos) for certain Services and Web Applications (e.g. via the ModifyService or Modify/CreateApplication AutheEnabled property)?

Thanks!

I am trying get the Unix time stamp  in milliseconds

set epochSecond= $ZDATETIME($ZTIMESTAMP,-2)*1000

but the result is not accurate as $ZDATETIME ignoring /truncating  the fraction of the seconds and the milliseconds calculation is not accurate with fraction seconds

for example

set epochSecond= $ZDATETIME($ZTIMESTAMP,-2)

1675830682

when its converts to the milliseconds

it became 1675830682000. not the accurate fractional seconds. 

My target system looking for the milliseconds time stamp to authenticate. 

Could you please help with steps to return the unix timestamp in milliseconds

Thanks

Hello guys,

i try to call a Operation within 3 foreach loops. 

When i try to do this, i always get the following error: 

I dont get any Errpr when i log my request message at this time i want to call a operation. 

Everything works and i get no error. But when i try to call the operation i get this error.

Then i tried to call a operation in the first Level (not in a ForeachLoop) it works. 

I simply call the operation with the RequestMessage from my Service.

When i now try to copy this call into the third Level (within 3 foreachloops) Then i also get this error.

I dont know what i am doing wrong.

Hello, friends who are developing IRIS. I recently participated in the InterSystems Developer Tools Contest. This time, I made a tool based on the idea described in an article I published earlier as a template for quick query of messages. Currently, you only need to establish entity classes in IRIS, Then record the message corresponding to the entity class in the specified lookup table, and all the key fields generated in the message can be inverted indexed (the concept in ElasticSearch), which is convenient for quick query. The following is the design idea of my program.

So, I know that I can return a SQL Error message from my SQL Procedure written in ObjectScript, with code like this

$ cat <<EOF | irissqlcli iris://_SYSTEM:SYS@localhost:1972/USER
CREATE or REPLACE PROCEDURE test()
LANGUAGE OBJECTSCRIPT
{
 SET %sqlcontext.%SQLCODE = 400
 SET %sqlcontext.%ROWCOUNT = -1
 SET %sqlcontext.%Message = "test error message"
};

CALL test();

EOF
[SQLCODE: <-400>:<Fatal error occurred>]
[Location: <SPFunction>]
[%msg: <test error message>]

But I did not find how to do it with Python. I can't find %sqlcontext variable available there
