#JSON

12

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

There are several options how to deliver user interface(UI) for DeepSee BI solutions. The most common approaches are:

  • use native DeepSee Dashboards, get web UI in Zen and deliver it in your web apps.
  • use DeepSee REST API, get and build your own UI widgets and dashboards.

The 1st approach is good because of the possibility to build BI dashboards without coding relatively fast, but you are limited with preset widgets library which is expandable but with a lot of development efforts.

The 2nd provides you the way to use any comprehensive js framework (D3, Highcharts, etc) to visualize your DeepSee data, but you need to code widgets and dashboards on your own.

Today I want to tell you about yet another approach which combines both listed above and provides Angular based web UI for DeepSee Dashboards - DeepSee Web library.

Hi,

I know there are several alternatives, but I would like to find the easiest & simpler ones to store data coming in Json format from post requests and also allowing me to do SQL queries.

I want to have a property called favouriteColors. I want to store a few colors, and I want to be able to do queries to get top favorite colors, etc... so not handling the list of colors as just a fixed string or fixed object.

What if you could serialize/deserialize objects in whatever format: JSON, XML, CSV,...; attending different criteria: export/import some properties and not others, transform values in this or that way before exporting/importing,...; and all of this without having to change the class definition? Wouldn't that be great??

Well, perhaps it's a goal too ambitious to reach 100% but, exploring this idea, I've developed a bunch of classes that I thought it was good to share. If you want to test, change, modify or improve the code, or just take a look at it, you can do it here. There you'll find a more detailed explanation (see Readme.md)

Be aware, this is a proof of concept for myself done in spare times, sure it's not robust enough or it can be done much better... but, I was just playing...ok, I could just wait to the new JSON Adaptor (coming soon!) that sure is going to resolve much more scenarios in a cleaner way, but... meanwhile... :-) ...

I need to convert an array with an unknown number of indices to a JSON string for transmission (which is why it isn't possible to iterate through it using $ORDER). Does ObjectScript provide functionality to convert an array to a JSON string?

Edit 1: As Joel mentioned, the array is subscripted and has an arbitrary structure like:

a(1)="a"
a(3,4)="b"
a(3,6)="c"
a(5,6,7)="d"

which needs to be converted to

Hi,

The class %JSON.Adaptor is very convenient,

I wonder if anyone faced the following scenario using it-

Exporting an object, that has a many to many relationship, and getting the details of the related objects.

For example, if we have three classes - Teachers, Students, and an intermediate class TeacherStudent .

The classes extend %JSON.Adaptor, and we would like to open a Student object, use %JSONExport, and get a JSON

That includes the details of the student and all the teachers that teach the student, something like:

I am writing an API that sends over a very large JSON object.

The code I'm using to get the data is actually used in our production system today for the use of writing a report.

However when I call the code using the API (using SoapUI) I am getting 'Error getting response; java.net.SocketTimeoutException: Read timed out'

The web applications settings have a session timeout setting at 15 minutes, but this is timing out within just a few minutes, so I know it's not hitting this mark.

How to send a file via JSON

I have a text file that I pick up in a Business Service and need to send it to our vendor via JSON. I assumed (probably wrongly) that I could just create a RESTful Business Operation, plug in the server IP and URL as well as complete some of the other fields on the BO to send the file. When I do this, I get the following error:

Hi All

I this article I detail some strategic issues that a new development UI will need to address - these are the ones that I can think of now - others may come to light during this journey.

See the webinar by Eduard Lebedyuk here from the last Global Summit describing modern web development and Caché

And, as always, if I have missed something please comment....

Good morning -

I am attempting to pass some HL7 content (say, a complete ADT message) from one server to another via REST/JSON - for reasons.

I can get the data across but when I try to create an EnsLib.HL7.Message object from the message in the JSON body, I end up with just the start of an HL7 msg in the resulting object. Looks like: MSH|^~\&

The start of the code accepting the data looks like this:

Cogs Library

Cogs Library

Over the next few months I will be releasing a number of open source libraries and tools to the Caché community.

Most of the code has evolved from previous production grade solutions over the years and I am collating it together under a single overarching library package that I am calling Cogs.

Hello community,

I am trying to parse the below HttpResponse in Cache. Cannot get the Iterator to work. Is there a single loop which can parse both or single messages and grab the error?

{
error:[
{ txt1:'error msg1'},

{ txt2:'error msg2'},
]
}

{
error: {
txt1:[
'error msg1',

'error msg2'
]
}

Thanks,

Jimmy Christian
