I'm looking for some help with JSON notation for a global structure. I need a way to represent a global structure in JSON where the global structure both has a value at a given node as well as sub-nodes.
It is easy to receive JSON representation or dynamic Array from %ListOfDataTypes:
set l=##class(%ListOfDataTypes).%New()
do l.Insert("a")
do l.Insert("b")
do l.Insert("c")
set arrStr=l.$toJSON()
zwrite arrStr
set arr=l.$compose([])
zwrite arr
How to make backward conversion? How to receive %ListOfDataTypes from dynamic Array an JSON string?
How can I prevent large number truncation when using the DynamicObject and DynamicArray classes to create JSON in objectscript and then parsing the result in javascript. Are there any global settings that configure the output when using these classes?
I am looking at converting to the new DynamicObject and DynamicArray classes to build JSON. Our current (homegrown) JSON library forces string representation of numbers too long because of errors we were seeing with long numbers being truncated on the client, I am hoping to accomplish the same with the new classes.
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?
Is there any way that I can check the native type of an object script variable? (similar to the typeof check in javascript)
I see that the DynamicArray class uses the type of the variable for its output, I would like to do something similar when I receive a value as an argument to my method.
I'm working on a REST service which will include a binary stream as a request property. I'm currently encoding the stream as BASE64 and passing it as a string value, but I was wondering if there is anything in the Caché JSON support that may be a better fit for encoding this data? Thanks Chris
My organization has been tasked with parsing raw EDI 271 messages into JSON strings in order to feed a downstream application. A few key details about the task:
We're creating a series of RESTful APIs that output data from a Cache database (made up of global storage that we've mapped to classes). I'm running into some problems with object-to-JSON conversions when relationships are involved. Eg:
ParentClass has children relationship to ChildClass
Hi, all.
I have CSP application and it needs to get and process data from ajax request with json-content. JSON can be very big.
In this case:
TRY
{
Set RequestObj = ##class(%Object).$fromJSON(%request.Content.Read())
} CATCH(Exception) {
Set Status=Exception.AsStatus()
}
I get just part of getting JSON and validate error in $fromJSON.
If I try to read it all in cycle:
TRY
{
While (%request.Content.AtEnd = 0) {
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.
I've generated a dynamic resultset and now doing the json and I can get Array's with nested Objects but I'm trying to get to Objects nested with another object
I have a Cache classes with %TimeStamp (e.g. 2016-04-18 12:29:11) and %Date (eg. 64027) properties. And I have a javascript client app, which needs full CRUD over this properties.
But in javascript date/time are defined by ISO8601 (e.g. timestamp 2016-04-18T12:29:11Z, date 2016-04-18).
MessagePack is a binary-based efficient object serialization library. It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small.
I have been experimenting with the creation of a set of REST services for an app. The basic GET operation is set to create a %ZEN.proxyObject instance, and then set an instance of a Persistant class as a property, which gives me all of the values I want to return. However, it also gives me some values that I don't want to return over REST (because they are both private, and large registered objects which will bog down performance)
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(),!
