#JSON

12

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write.

All time

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?

Methods written in ObjectScript can use pass-by-reference arguments to return information to the caller. Python doesn’t support pass-by-reference arguments, so Embedded Python in IRIS doesn’t support them either. That's it, that's the end of the post, hope you liked it. 😉 But wait, what about the Classic Rock & Roll?

There are couple of options to do this.

1. You can extend your class &JSON.Adaptor, it will do it for you with inbuilt logicaldtodisplay methods

2. Create another request class and do your transformations

3. Before calling the json convert to stream methods, transform the object's field with a ZDT.

I have an extremely simple example where there is a class with 3 properties

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:

Dear Colleagues and Friends,

is there any indication that the .NET object representation of Cache objects (i.e. InterSystems.Data.CacheClient.dll) complies with .NET Standard? I'm planning to extend our existing .NET client/server solution with a mobile option by Xamarin Forms and can't find any significant hints in the internet.

I'm just fooling around a bit and made some expreiments with a REST API and a generic object-to-JSON tier:

Hello community,

I'd like to briefly announce three new packages, available on the Open Exchange / through ZPM, that can really help accelerate modern full-stack application development on IRIS. I announced all of these in a Global Summit session last week, but you may have missed it - and I hear there's a full-stack application development contest coming up!

Hello Community,

My Intersystems Caché Version: 1.2014 (Can't update now.)

I have the following issue:

I have for example an articlenumber with 15049950, which is numeric. But sometimes it can also be an alphanumeric string like PK15049950.

How can i set numbers always to string in Json Stream with quotes like "15049950".

Code Example:

set object = ##class(%ZEN.proxyObject).%New()

set articlenumber = "15049950"

set object.articlenumber = articlenumber

How to start Using VsCode

Introduction

In the next few weeks, my coworkers are planning to start using VSCode to code with InterSystems' products. Among the many advantages of that, I would emphasize being able to connect with other technologies, such as GitHub, with ease. Besides, VSCode also offers an extensive extensions store, where you can find many free add-ons that make coding faster and more efficient. Last but not least, to conquer the heart of every developer, it is open source.

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.

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.

Create JSON Objects and Arrays by SQL

The related package avoids adding %JSONAdaptor to each class but uses instead
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships as JSON objects or arrays.

Hi community,

I am looking for an implementation strategy to create/update organizations in a local ISC based FHIR server. Thoase organizations do have a certain dependancy to one another. For Organization resources the "partOf" property symbolizes that. It is planned, that a Interoperability Production (supporting FHIR Server) receives a bundle which contains a batch export of all organizations of a customer (Hospital). The task is to bring those data into the FHIR server create and/or update organization.

You may have heard about our mg-dbx-napi interface for IRIS which provides insanely fast access from Node.js. If you've been following recent developments in the server-side JavaScript world, you'll be excited to know that mg-dbx-napi also works with Bun.js, the latter proving to be significantly faster than Node.js for many/most purposes.

Of course, if you're a Node.js user, you'll probably wonder how mg-dbx-napi compares with the Native API for Node.js that is included with IRIS.

2015.2.2 .json format

Is it possible to produce a .json format using Ensemble 2015.2.2? Not sure what the trigger will be as of yet, but we have our local Department of Health trying to develop a reporting piece using .json.

Not sure how this will work with our Ensemble instance not being in the DMZ to send outside our network, but I thought I would ask anyway to see if it is possible.

Thanks

Scott Roth

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.

Hello

I am creating an import tool to convert a client's JSON data into IRIS classes. The sample file is over half a gig. I am copying the data into an instance of %Stream.FileCharacter;. My first few attempts worked fine. However I started getting an error thrown when I try to create a DynamicAbstractObject using the %FromJSON method. See the code below. The error code given is not in the documentation, at least not the doc that I was searching.
