Why I've decided to write this

Once again I had a challenge that costed me some time and a lot of testing to reach the best solution. And now that I've managed to solve it, I'd like to share a little bit of my knowledge.

What happened?

In a namespace there were a lot of similar classes, so to make them simpler there were a superclass with comon properties. Also, there are relationships between them. I had to export one of them to JSON, but I couldn't change the superclasses, or I would break down the flow of many other integrations.

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.

JSONfile-to-Global #1

The similarity between JSON objects + arrays and Globals in IRIS or Caché is evident.
With small and medium size JSON objects navigation across %Dynamic Objects is comfortable.
But with large and/or deep cascaded objects it becomes a challenge.

The presented tool offers 3 variants

  • loading an already existing %Dyamic object or Array into a global of your choice
  • loading a %Stream containing a JSON object into a global of your choice
  • loading an external File containing a JSON object into a global of your choice

Hi Developers!!,

I know what you are thinking... a new feature for ZEN.proxyObject...? NOW..???

In Spain we say that better late than never ;-)

Have you ever need to send a numeric attribue of a Json in String format?

Did you go crazy casting class objects with fixed typed properties?

Lucky you!!

With this new feature I propose a way to continue working with our loved dynamic object %ZEN.proxyObject, being able to choose whether or not we want to send numeric attributes in String format.

REST JSON webservices presentation

Hello Community!

This article gives an overview of the REST JSON webservices developed for TrakCare.

These webservices allow users to access TrakCare data from outside of the software, mainly through external apps.

They are developed in REST with ObjectScript, and they allow data access in four modes:

Creating a RESTful Service using Ensemble

This is a detailed guide to develop RESTful services using InterSystems Ensemble. The goal of this guide is to make you understanding the basic concept and building blocks of a RESTful service. The service is going to provide a very basic functionality (a “Hello world!”).

You will learn how to create required components as Ensemble classes, configure the run-time as an Ensemble Production and create a service configuration as a web application.

I've tried to convert it directly into a DTL, but all my attempts have been unsuccessful

Best regards,

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:

Hi there,

I'm passing a JSON object to the server as such:

{"key":"value","key":"value","key":"value"}

From the client:

- Build object

object=JSON.stringify(object)

-pass to server side method as %String

On the server:

s object={}.FromJSON(object)

Instead of getting something like

object=<OBJECT REFERENCE>[2@%Library.DynamicObject]

I get

object="991@%Library.DynamicObject"

I can't access that object using %Get as if says invalid OREF.

MAXSTRING limit issue

MAXSTRING (longstring) is enabled.

We have a Class containing a property definition

Property SettingsJSON As %Text(MAXLEN = 3600000)

The property is used for storing a string of JSON data however in some cases we get a Cache error: %SaveData error when trying to save a string of JSON a lot less than maximum "allowed" length, any ideas anyone?

Time handling and Json

I am having trouble formatting %Time to a JSON format. I have tried configuring the parameter "FORMAT" of my property but that didn't work. For some reason, it keeps putting a Z and the end of the time.

Property:

Property TimeCollected As %Time(FORMAT = "2");
