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:
The article is a step by step guide for beginners to learn how to build a RESTful web service consumer (or client) in Ensemble. The provider can be any RESTful service, but the example is based on the service we made during the previous sessions.
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
A beginners guide to develop Ensemble RESTful web services.
Background
Before you start reading this short introduction please go through the on-line documentation of Ensemble with special attention to chapter “Creating REST services and clients with Ensemble”.
The approach in the documentation is undisputable the fastest and easiest way to create RESTful services. As a beginner I went through the documentation and I had several questions. This short article is listing those questions plus my humble answers.
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) {
Recently I have been posting some updates to our JSON capabilities and I am very glad that so many of you provided feedback. Today I would like to focus on another facet: Producing JSON with a SQL query.
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.
The field test of Caché 2016.2 has been available for quite some time and I would like to focus on one of the substantial features that is new in this version: the document data model. This model is a natural addition to the multiple ways we support for handling data including Objects, Tables and Multidimensional arrays. It makes the platform more flexible and suitable for even more use cases.
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 am pleased to announce the next 2016.2 field test kit, 2016.2.0.595.0.
It may look like a slow week, with less than fifty changes having been checked in, but this kit includes the following fixes to problems found by you, the ones running the kits in the field:
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(),!
