Saw the other day an article with the usage of the %ZEN package when working with JSON and decided to write an article describing a more modern approach. At some recent point, there was a big switch from using %ZEN.Auxiliary.* to dedicated JSON classes. This allowed to work with JSONs more organically.

Thus, at this point there are basically 3 main classes to work with JSON:

• %Library.DynamicObject - provides a simple and efficient way to encapsulate and work with standard JSON documents. Also, there is a possibility instead of writing the usual code for creating an instance of a class like

set obj = ##class(%Library.DynamicObject).%New()

it is possible to use the following syntax

set obj = {}

• %Library.DynamicArray - provides a simple yet efficient way to encapsulate and work with standard JSON arrays. With arrays you can use the same approach as with objects, meaning that yu can either create an instance of the class

set array = ##class(%DynamicArray).%New()

set array = []

Someone, please point me to the location of the cache ODBC drivers, as I only found IRIS ODBC drivers.

Hi everyone,

My problem today is how to send an HTTP message to a web service deployed via Render and gunicorn.

Issue

Every time I try to contact the web service I get an error. Searching on the web, I've found this StackOverflow question that suggests the issue could be set off from a missing "/" character in the endpoint string.

Could you please help anyone how to import Python package in %SYSTEM package and to use python methods to write in object script class?

I used the following link to install the Python but I can't see the Python package in %SYSTEM package and my program throwing the Class Does not exist error?

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

Please help on this..

I didn't understand this error report. Can someone tell me what it means。

thanks

Hi Community!

We have a couple more things to share with you about the workings of the Tags and Groups on the Developer Community.

First of all, if you're curious about where you can find the list of all Tags and Groups, it's in the Menu -> Posts -> Tags

Hello,

I have a problem attempting to store a base 64 encode stream into the OBX:5 field of a HL7 message, by using the StoreFieldStreamBase64 method.

I'm using a transformer to input the contents of a pdf within a stream container (Ens.StreamContainer). The output is a HL7 message (EnsLib.HL7.Message 2.5:ORU_R01).

The transformer is being used in a business process.

This is the code used in the transformer to encode the stream to base 64:

Pointers please for debugging a SOAP web-client.

We have several clients in different productions all accessing a web-service. We are trying to add another client in a new production, and its not working. The messages between the relevant Process and the SOAP web-client Operation are the same in the working and the non-working productions. But the web-service is reporting an XML parsing error to the non-working production. Here's the error as reported in the SOAP web-client Operation...

Hi Community,

Hello Community,

I've created my FHIR patient profile and POST into FHIR endpoint in Intersystems FHIR Server.

http:localhost:52773/fhirr4/StructureDefinition

I use the profile url into my Patient resource without the meet the profile requirements.

http:localhost:52773/fhirr4/Paient

The resource is stored successfully in the FHIR Server instead of a FHIR exception.

Why the resource doesn't validate with the mentioned profile?

Hello community, I need to solve a complex but trivial issue.

Given:

Two tables "Comment" and "Post". Each one contains an "Author" field, which is essentially a user ID. In these tables, each user ID represents an author. The goal is to count all participants together and then group them by month, language, and other metrics.

The question is how to do this within the IRIS ecosystem. Is it even possible to take two tables, get distinct data from them and then combine into one cube?

Hello Community,

I have couple of question about the DynamicSQL.

1. The %ObjectSelectMode is working perfectly in the DynamicSQL for the object property in direct query. However this is not supported for class query. Is there any way to resolve this / Get the object value for class query result.

InterSystems FAQ rubric

ObjectScript allows you to pass any number of arguments using arrays. Do it by adding ... after the argument name.

An example is as follows. In the example statement, the argument information is set in a global variable (a variable stored in the database) so that it can be easily checked after the method is executed.
