JSON - NULL Properties

So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.

1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.

2. I'm not really confident enough to create JSON Type classes or backporting code, etc.

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?

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

Running Cache 2017.2.2.

I'm trying to make a REST API call in JSON format. When using the example in the class reference documentation the getJSON method in the %Net.Http class throws the error <METHOD DOES NOT EXIST> on a %Clone() method in the %LIbrary.DynamicObject class. I even changed the parameter to a JSON string to no avail. The code will then fail on the %Compose method (examples below). My workaround is to use the %Net.HttpRequest functionality. Is there another workaround to this?

Hi everyone,

I am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)

So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.

What changes are to be made while customizing a FHIR server package when adding a new field. As provided in the documentation, we have a sample JSON package of favorite color and it is added in the table, but when we are adding a new field 'Insurance', it does not imports the package and says package already exists. We have three files of JSON

1) Package.JSON

2) SearchParameter.JSON

3) StructureDefination.JSON

What should we have to change for adding new field.

Hi,

I am trying to use data transformation (DTL) to map a JSON to SDA. My elements in the source JSON is not one to one with SDA object. That means I have to add code to loop through these objects in order to complete the mapping. Can someone send me a sample that can look to create that? I am not very comfortable with scripting language used in Health Share. Appreciate your help.

Regards

Joseph

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:

%FromObject+21^%Library.RegisteredObject.1 *%Exception.General Compose Compose %FromObject Unable to map frm %Library.Array instance to %Library.ListOfDataTypes

I have reading about this but I don't found some trick to help me.

JSON to HL7

I have a project to convert a JSON message with two patient identifiers into an HL7 ADT^A31. Is there any documentation or training that you would think is appropriate?

Parsing null values in JSON

Hello everyone,

I'm creating a REST API with InterSystems Ensemble.

I already have a POST route that parses JSON content into an object defined in a class.

To parse the JSON content, I'm using the JSONStreamToObject method in the Ens.Util.JSON class

Here is how I use it:

I'm revisiting some older projects that can benefit from the new JSON support and dynamic object capabilities in 2016.1 FT / 2016.2 FT. (Particularly, some of the really new features in the latest 2016.2 FT.)
For the particular thing I'm working on, it would be very handy to be able to merge objects, similarly to https://api.jquery.com/jquery.extend/. The closest thing I've found so far (in 2016.2 only) is:

Set o1 = {"a":1,"c":2}, o2 = {"b":1,"c":1}
Write "o1: ",o1.$toJSON(),!
