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 folks,
I have an JSON object that need to be updated before being parsed into a JSX component.
Source JSON obj:
var Obj = { "data": [
{"id":1, "text":"Task #1", "project":"10", "sub_project":"10-1" },
{"id":2, "text":"Task #2", "project":"10", "sub_project":"10-1" },
{"id":3, "text":"Task #3", "project":"11", "sub_project":"11-1" },
]};
Required JSON obj result:

Hello,
I'm trying to convert JSON response to object in cache 2010.
My Code is bellow:
Hi Community!
Suppose I have a property in a ObjectScript class:
Property values As list Of %StringWhat an SQL query can help to return the values of the property as JSON array via SQL access (JDBC)?
Hi All,
I am trying to get JSON data from a REST api. I am using my web browser to get the data by hitting the URL.
The data is receiving properly, but the JSON contains a few HTML tags.
These tags are not not receiving in the browser while hitting the url. Is there any way to overcome this issue ?
Thanks,
Hello.
I just noticed that whenever I parse a JSON using %FromJSON, it always return the property values as primary data types, including long strings.
This post is intended to guide you through the new JSON capabilities that we introduced in Caché 2016.1. JSON has emerged to a serialization format used in many places. The web started it, but nowadays it is utilized everywhere. We've got plenty to cover, so let's get started.
I created the Process to extract the required data from ADT message to a Dynamic Object. I wanted to send the JSON stream to EnsLib.File.PassthroughOperation operation and generate a file with the content of JSON stream.
Here are the codes for Process:
Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. In the previous part, we created a basic front-end React application. In the second part of this article series I will show how to choose the right back-end technology for your application. You will see Caché allows you to use many different approaches to link your front-end to your Caché server, depending on your application's needs. In this part we will set up a back-end with Node.js/QEWD and CSP/REST. In the next part we will enhance our basic web app and connect it to Caché using these technologies.
So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.
There's only one problem: You've never used Angular, and don't know how to make it talk to Caché.
This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.
Hi all,
I have an incoming JSON message with a string field exceeding in length the 'caché long-string limit' of 3641144 characters.
Using {}.%FromJSON(instream) I am able to create %DynamicObject properly. However, I am unable to access the long property, as in every assignment, I get the <MAXSTRING> error.
Is there any way for me to obtain contents of the 'too long' string field as a stream?
Thanks

When using the JSON_OBJECT() function in Caché SQL on a %String property that contains JSON syntax, it converts the %String into a JSON object instead of escaping it as a string literal. How can I prevent this? (without ridiculous hacks like "add a space to the beginning of the value" as we don't always know which properties will contain these values and I certainly don't want to have to check for nulls and add/remove a space every single place this value is used in the application)
I don't want these strings automatically marshalled into JSON objects.
For example:
I am trying to use the automated unittest class for a %CSP.Rest service.
So my Unittest code set's %request and %response from %CSP.Req/resp respectively
I build a tProxy with the fields I need for the post and set it %ToJson... I have tried seting %request.Content = tProxy (and not)
I call the method for the post url directly...
When that method calls %fromJson to set an object with the info. I passed...
- when I don't set %request.content.. I get a error '5035 - premature end of data code 12'
This is my testClient:
Full-Stack JavaScript development allows you to create state-of-the-art applications with Caché. With any (web) app you build nowadays, one has to make a lot of architectural decisions and you want to make the right ones. With the Node.js connector available for Caché, you can create a very powerful server side application server, allowing you to use the latest JavaScript technology and frameworks client- and server-side.
With all these new technologies, the most important is to integrate them in the most efficient way and to create a very productive development experience. This article willl get you started step-by-step with Node.js technology.
Recently, a partner company started to develop an Angular client for their Cache application. Together, we decided to leverage the power of Caché dynamic objects to exchange JSON encoded data between client and server parts. However, we realized that currently there is a gap in Cache JSON implementation that prevents simple use of traditional registered and persistent classes to exposed their data with the same ease as with XML. I wrote a small JSON adapter, that does the job and bridgers the gap. It's purpose is simple expose data described by a regular Cache class in a one-to-one fashion to a %DynamicObject. On the other hand, when a serialized JSON data comes in, it can be easily deserialized into dynamic object and subsequently bound to regular class by the newly created adapter.
Hello everyone,
i want to create an iris document database with Atelier with some properties, where i can import my JSON formatted data from an API to the database which i created. Right now i know how to import my local JSON formatted data to my created database:
Hi everyone,
I need submit a object have a json string as property of class, but I get an issue, object can't save to SQL table if I take json data to json property. I try making a test class with only json property and get the same issue, no data row in SQL table after run ClassMethod . Some one know what's problem, please help me. Here my test class:
Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. In this third part of this article series I will show how to link our React app to our three back-ends we created in part 2.

404 Not Found

I want to do something like the above sample from a Google Storage JSON API. I have a call to Write obj.%ToJSON() followed by return ..ReportHttpStatusCode(..#HTTP404NOTFOUND) however the HTTP Status code is always 200. If I remove the Write obj.%ToJSON() statement it returns a 404 status with no body. How do I return both?
Generally speaking, InterSystems products supported dynamic objects and JSON for a long while, but version 2016.2 came with a completely new implementation of these features, and the corresponding code was moved from the ObjectScript level to the kernel/C level, which made for a substantial performance boost in these areas. This article is about innovations in the new version and the migration process (including the ways of preserving backward compatibility).
Hello,
We are running cache version 2012.1.4
Is it possible to make an HTTP Post passing in JSON string?
Example:
I want to send this request to Authorize.net. How can I do this in cache object script?
URL: https://apitest.authorize.net/xml/v1/request.api
Body:
Hi,
we have Angular solution and Cache server. We need to have separate users and sessions on same browser (laptop, table etc) for every user and for one user with many connections.
Thought this was resolved, but unfortunately not.
-----------------------------------------------------------------------------------------------------------------------
I got the code away from here, because it was some how ok.
The session on server mixed, but no any more, thanks our folk and local engineer's tools :)
In a EnsLib.REST.Operation I have...
Set tSC=..Adapter.Post(.tHttpResponse,,pRequest.stream)
This sends JSON string over HTTP
I am getting this error back from the server
Hi everyone!
Someone already try to use jQuery Mask Plugin on cache?
