Hello Community!

I'm going to try to explain how to create test for Postman collections for use it with my app IRIS Api Tester.

Yet, What is Newman?:

Newman is a command-line tool that allows you to run Postman collections in an automated and scalable way. By creating tests in Newman, you can ensure the reliability and correctness of your API endpoints. In this article, we will explore how to create tests for Newman in Postman, along with practical examples to help you get started.

For volatile tables (tables with many INSERTs and DELETEs), storage for bitmap indexes can become inefficient over time.

For example, suppose that there are thousands of data with the following definition, and the operation of bulk deletion with TRUNCATE TABLE after being retained for a certain period of time is repeatedly performed.

Class MyWork.

My major interest is  Working with Globals in Embedded Python.
So I checked the available official documentation.

#1 Introduction to Globals
an attempt of a generic description of what a global is. Pointing to

#2 A Closer Look at ObjectScript
But where is Embedded Python ?
Way down you see

#3 Embedded Python

3.1 Embedded Python Overview
3.1.1 Work with Globals
Great if you have never seen a Global before
Otherwise a shocking primitive example

Last hope: >>> but there is just NOTHING visible.
This is more than just disappointing! Even IRIS Native API for Python is more detailed.

Hi folks!

How can I refer to a classmethod of the same class while coding another classmethod with Embedded python?

I know that I can call it with iris.cls(classname).MethodName(), but it's more cumbersome even comparing with ObjectScript, where I can call ..MethodName().

Compare ObjectScript:

do..SetupGame()

and the same call in EmbeddedPython:

    iris.cls('eshvarov.sample.SeaBattle.GamePython').SetupGame()

Thoughts?

Hi All,
I was creating a unit test directory with the below script. But it not creating any directory as mentioned in code. I am working on MacBook with irisusr User as standard installation process.

if '$data(^UnitTestRoot) {

set mainFolder = "UnitTest\NewDir\"

set st = ##class(%File).CreateDirectoryChain(mainFolder _ testSuite)

if $$$ISOK(st) { set ^UnitTestRoot = mainFolder }

else {

write !, "UnitTestRoot folder could not be created. Consult with instructor."

do $system.Status.DisplayError(st)

}

}

Getting INVALID OREF error while unit testing. Also ResultDyanmicObj.Headers.%Size(),DummyResponse.Headers.%Size() these are working fine getting 7 value from both. but still it is not working.

do $$$AssertEquals(ResultDyanmicObj.Headers.%Size(),DummyResponse.Headers.%Size(), "Validation for Headers")

error - INVALID OREF>TestAccountSearchWithoutAccount+6

Hi All,
I want to write testcase in objectscript but stuck at this point where I am getting a DynamicObject from the class method and how can I assert this and check it is okay. 
Also if in any case error It will throw error custom exception class that I created. How to handle assertion for exception in this case also.

Hi All,

I am trying to execute my SQL query using ExecDirect() method and it returns a ResultSet. No doubt it works fine after this I am trying to fetch each value using a loop code below. But before that, I am also checking for %SQLCODE = 100 which is for an empty resultset I think. However, It is not working as desired. In the case of an empty resultset also I am getting %SQLCODE = 0 until result.%Next() is called. Also, %ROWCOUNT is giving 0 in a case where my query is return 1 result row. I am so confused about this.
while resultset.%Next() {

// code

}

I have latest VS Code 1.50.1 and latest ObjectScript extension.

For some unknown reasons, my IRIS icon disappeared from VS Code activity bar.

How can I get my IRIS icon back?

Has anyone come across a good using Embedded Python to convert a Python List object to an IRIS %List object?

My use case is I want to open an SQL entry with an Objectscript class method, then pass some information from that row into a separate Python class method which will then create a Python List object, then have the Python class method return that list back to the Objectscript class method in such a way that the Python List can be converted to an IRIS %List object for me to then use in the Objectscript code.

Hi folks!

I have a need to use symilar to $property function from Python. Here is the code:

obj=iris.cls('some.persistent.class')._New()

for property, value in data.items():

 $property(obj.property)=value ; I invented this

How could I do this? Any trick?

For now I plan to implement a helper function in iris that I will call, but I doubt also how can I transfer oref to IRIS.

Thoughts?

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

Hi all,
I have install git-source-control to the namespace TEST. Also it is working fine as I am able to add files to my local git repo and see the changes in it.
But while I try to open GUI for the same i am getting service unable error on this URL

what's wrong with this.

IoT (Internet of Things) is a network of interconnected things, including vehicles, machines, buildings, domestic devices or any other thing with embedded TCP/IP remote connection available, allowing it to receive and send execution instructions and data. Each thing provides one or more services to the IoT network. For instance, smart light bulbs provide services of turning off and turning on the lights; smart air conditioners maintain the environment temperature; smart cameras send notifications when capturing movement.

Hi everyone.

Has anyone here had any luck with receiving a DICOM C-FIND-RQ and returning a worklist using data gathered from a non-DICOM source (for example, an external SQL query) and would be able to share how they achieved this?

I started to look at the demo however I'm tripping over the logic for building the response.

Hi,

Looking for some guidance on setting up IRIS to use single sign on to authenticate with ADFS. 

We have a request for users to automatically launch IRIS without the need to login, the user will be authenticated by Single Sign on (SSO) against ADFS.

Do we need to have a authorization server as well as a client, ADFS will handle all the authentication side,  so would it be a case of configuring IRIS client up to communicate with ADFS, following the link below?

OAuth Configuration

Appreciate any help or advise given.

Thanks in advance. 

Hello, 

Our team is working on building dashboard for internal reference and monitoring. 

We would like to have details like Interface Name, Current Status, Last Messages Processed at, IP & Port, Serve/Instance/Production Environment name etc. 

If there is any built-in service which we can utilize or any pre-compiled code that we can utilize to build such dashboard. 

At this moment want to keep it basic, but moving forward will enhance with more advance features. 

Please suggest, any help will be appreciated. 

Thanks,

Yash 

As you all know, the world of artificial intelligence is already here, and everyone wants to use it to their benefit.

There are many platforms that offer artificial intelligence services for free, by subscription or private ones. However, the one that stands out because of the amount of "noise" it made in the world of computing is Open AI, mainy thanks to its most renowned services: ChatGPT and DALL-E.

Hi Community!

Have you ever had to connect IRIS to an SAP system?

I had to face the challenge of connecting InterSystems IRIS with SAP, and once again I was able to verify the grant work made by Intersystems related to adding the possibility of executing native Python code inside IRIS.

This feature made the integration very easy thanks to the library pyrfc.

With this library, I was able to make calls to a SAP RFC (Remote Function Call) from an IRIS class and receive data from the SAP’s database. 

Yet, What is a RFC?

RFC is a communication protocol used by SAP.

Hello all,
I am creating a REST API with a spec-first approach. However, I am using the try-catch method to handle any exception if any occurs. But whenever any error related to syntax or something occurs, we get internal server error 

{

"errors": [

{

"code": 6220,

"domain": "%ObjectErrors",

"error": "ERROR #6220: Internal Server Error",

"id": "InternalError"

}

],

"summary": "ERROR #6220: Internal Server Error"

}

This is I think IRIS defined, I want to customize my own Internal server error. 

Hi folks!

Just curious, how can I use $znspace in embedded python code?

How does other $functions work, e.g. $zv, $job, etc

Hi folks!

Consider I need to call a python function which name contains "_" symbol (which is quite often in Python). How it could be called from ObjectScript?

E.g. here is the code:

Set sm = ##class(%SYS.Python).Import("sample")

write sm.helloworld() ; function without _
white sm.hello_world() ; function with _ - won't compile.

Thanks in advance!

Hi, Developers!

I wonder if it is possible to use class parameters in DTL XData?

E.g. in an example below of the DTL I'd prefer to setup ChatGPT prompts in parameters (GPTPrompt1) of DTL rather than quotes inside the XData XML:

If possible, how can I refer to a class parameter from XData?

Thanks in advance!

Countermeasures against SQL injection have been published on various websites, but we believe that it is possible to prevent SQL injection in applications using InterSystems SQL as well as other RDBMS by implementing these countermeasures appropriately. In addition, InterSystems Data Platform (hereinafter referred to as IRIS) incorporates several measures that make SQL injection more difficult than general RDBMS.

Hi folks!

I have an example where I want to write a string into a file.

I have a message with string and I want to write the string down into a file.

I took EnsLib.FilePathThrough.Operation which expects Ens.StreamContainer message.

So I perform a data transformation where I need to transfer string to a stream. Here is the DataTransformation:
