#ObjectScript

Hi Developers!

Suppose you have a persistent class with data and you want to have a simple Angular UI for it to view the data and make CRUD operations.

Recently @Alberto Fuentes described how to build Angular UI for your InterSystems IRIS application using RESTForms2. 

In this article, I want to tell you how you can get a simple Angular UI to CRUD and view your InterSystems IRIS class data automatically in less than 5 minutes.

Let's go!

Hello, friends who are developing IRIS. I recently participated in the InterSystems Developer Tools Contest. This time, I made a tool based on the idea described in an article I published earlier as a template for quick query of messages. Currently, you only need to establish entity classes in IRIS, Then record the message corresponding to the entity class in the specified lookup table, and all the key fields generated in the message can be inverted indexed (the concept in ElasticSearch), which is convenient for quick query. The following is the design idea of my program.

Hi all,

In the days when I was still using studio, the indentation character of choice was tab, due to misalignment of code when using non-monospaced fonts.

In VSCode when I create new class files, this defaults to 4 spaces. Where and how do I set the default indentation for ObjectScript class files?

Also, with python it should be spaces. So what is recommended when doing python script inside objectscript classes?

Thank you.

Hi everyone,

I have been reading up a bit on projection. I found a reference made to %Projection.Monitor on this page.

However, I cannot find any further information on %Projeciton.Monitor. What is it? How does it work? How do you use it? What value does it add?

Thank you.

We have created a number of REST adapters that extend %CSP.REST and these have been working fine.  However, we are now facing a problem with a new one where very large XML documents are being posted.  This is the pattern we are following:

Set inMsg = %request.Content.Read()

Set tSC = ##class(Ens.Director).CreateBusinessService("Epro_ItkHttp",.tBusinessService)

Set tSC = tBusinessService.ProcessInput(inMsg, .tBusinessServiceOutput)

However, when the %request is particularly long, it is being truncated, and working with %XML.Reader then fails in the business service class.

When requesting /MDX2JSON/PivotVariables/Patients?Namespace Patients shoud be passed to a method but its not. When argument passed directly into the method it works.

Has something changed in IRIS and this syntax is deprecated, or is there a bug and the colon is ignored? What could it be?
This question is continuation from https://community.intersystems.com/node/534811

I have a system that is sending Line Breaks\Carriage Returns within the text of a field that is breaking the parsing of the message. Does anyone have a way to get around this?

here is what I receive...

as EnsLib.HL7.Service.

Hi *,

I want to dynamically generate the arguments of a method during compile time.

'For example, I want the following method

ClassMethod DoCleverStuf() As %Status [ CodeMode = objectgenerator ]
{
    do %code.WriteLine("    Set tSC = $$$OK")
    ...
}

to look like this in the .int code.

ClassMethod DoCleverStuf(pValue1 As %Integer, pValue2 As %String) As %Status [ CodeMode = objectgenerator ]
{
    // some generated code will be here
}

Is this possible? Or alternativel;y, can I generate a whole method at compile time?

Thanks.

Hi Guys

I've been using the example code %SQL.ExportMgr taken from here (an example from the intersystems community) an am having a few problems with it.

The code I have is below, and I'm having the following problems:

• Regardless of the dateformat property I use (e.g.  Set mgr.DateFormat = 1),  date data is always exported with format in YYYY-MM-DD
• Regardless of the timeformat property I use (e.g.     Set mgr.

Hi Community,

I have created a HL7 production in my working environment, Ens.Alert ,EMailAlert, PagerAlert, and  BadMessageHandler are created.

Can anyone explain how Ens.Alert and BadMessageHandler will work when an HL7 message in Passed in Business service and how these 2 are related when any error occurs in the Production envinorment?

Dear Friends

Please help me to create  %ZEN.proxyObject same in below example:

{

    "dynamicLinkInfo": {

        "domainUriPrefix": "link.example.com",

        "link": "https://www.examplelink.com"
    },

    "suffix": {

        "option": "SHORT"
    }

}

My Code

 // body
    set BodyObject=##class(%ZEN.proxyObject).%New()
    set dynamicLinkInfo=##class(%ZEN.proxyObject).%New()
    set suffix=##class(%ZEN.proxyObject).%New()
set DataObj=##class(%ZEN.proxyObject).%New()
set Data2Obj=##class(%ZEN.proxyObject).%New()
Set DataObj.domainUriPrefix= "link.example.

Hi all,

I am trying to use some process private variables (percent variables) in Triggers.

I am referring to values from $System.Process, like the ClientIPAddress and CSPSessionID.
These do to not contain values and I suspect it is bacause of scope. I also checked, and the %session variable is not available if the change originated from a CSP request.
I know that in triggers the scope of the variables are to be kept local, that is why NEW is to be used.

Is there a way to access the Process Private Variables in Triggers or get $System.Process to return the correct values?

Thanks.

Hi All,

Hopefully  someone can help me with this case. I need to encrypt a text(querystring) with an AES265 encryption. An other vendor is decrypting this information. I have a working class in C#. I've tried to build the same in Objectscript for the encrypt part but there's a missing link somewhere.  What's the difference between the C# and Objectscript implementation?

Objectscript code (until now):

Class TEST.ENCRYPT
{

// Symmetric Keys sample to encrypt

ClassMethod DoAESCBCEncrypt() As %Status
{
	set key="pZR8qfrz7t47G+dboyJCH4NnJRrF+dJbvxq37y/cLUo="
	set iv=##class(%PopulateUtils).

This article will describe and include an example of how to embed an external PDF file into an HL7 segment, specifically ADT_A01:2.3.1 OBX().  This can be useful when attempting to insert pictures or other external data into an HL7 message.  In this example, the name of the PDF file to be embedded is provided in the incoming HL7 message in OBX(1):ObservationValue field.

The basic stipulations for this example are as follows:

1. Accept a PDF file
2. Accept an HL7 message
3. Using the name of the PDF file, embed the PDF data into the HL7 message
4. Output the message to file 

 Using EnsLib.File.

Hi everyone.

I have a use case where I'm using embedded SQL within a Business Process to interact with a SQL table. However, when it comes to deployment into our production, the table wont form part of the deployment package created from the production.

Beyond manually creating the table on the production system, is there a standard way of ensuring that a table needed for a class is created during deployment?

Hi Community,

I am new to ensemble and cache object scripts ,i am trying to create a business service using Ens.BusinessService

but i have doubt what is the difference or uses between Parameters and property in defining classes in defining business service

Joe

I need to test specific values in %DeepSee.Dashboard.Utils. For that i have to change them but this appears:

ERROR #5883: Item '%DeepSee.Dashboard.Utils' is mapped from a database that you do not have write permission on.

How can i get past it?

In trying to define a Class Parameter that I can use in SQLComputeCode I can't seem to get any of the syntaxes for the using of the parameter where the SQL compute code will actually evaluate the parameter values. There is nothing specific that I can find in the docs about SQLCompute Code and Parameter usage.

Is there some specific syntax for accessing a class defined parameter in the SQL Compute Code that works?

Hi Developers!

"objectscript.conn" :{
      "ns": "IRISAPP",
      "active": true,
      "docker-compose": {
        "service": "iris",
        "internalPort": 52773
      }

I want to share with you a nice new feature I came across in a new 0.8 release of VSCode ObjectScript plugin by @Dmitry Maslennikov and CaretDev.

The release comes with a new configuration setting "docker-compose" which solves the issue with ports you need to set up to make your VSCode Editor connect to IRIS. It was not very convenient if you had more than one docker container with IRIS running on the same machine. Now, this is solved!

Read below how it works now.

Hi Developers,

⏯ Importing Relational Data Using a DDL Script

I am familiar with $TEXT which can get you any line in the current routine provided you know the offset. For example, $T(+1) will get you the first line of the current routine at the run time. In the same vein, how do I reference the current line number/offset at the run time? Something like $T(+$CURRENTLINENUMBER) where $CURRENTLINENUMBER is not yet known to me function. The sample below would write 3 as the line number.

What is Web Scraping:

In simple terms, Web scraping, web harvesting, or web data extraction is an automated process of collecting large data(unstructured) from websites. The user can extract all the data on particular sites or the specific data as per the requirement. The data collected can be stored in a structured format for further analysis.

Steps involved in web scraping:

1. Find the URL of the webpage that you want to scrape
2. Select the particular elements by inspecting
3. Write the code to get the content of the selected elements
4. Store the data in the required format

It’s that simple !

Was wondering if anyone had a simple way of calling  ##class(Ens.Director).EnableConfigItem() within a Business Process or adding code to a Custom Service to start or stop the object?

The use case is that I have a Process that uploads a file into a external SQL table. When it is finished I want it to kick off another Service that does the processing of the data that it just uploaded. Once it is finished the response is sent back to the service and when the service receives the response from the process, I want to stop that service from running.

so.

Hi guys!

My student asked my why his unit tests don't work as they should, and I just could answer him. Here is the simplified case.

There is a class with a required unique property Name:

Class Test.NewClass [ Abstract ]
{
Property Name As %String [ Required ];
Index NameIndex On Name [ Unique ];
}

And there is an inherited class:

Class Test.NewClass1 Extends (%Persistent, Test.NewClass)
{
}

What I expect to happen, is when I save two objects of class Test.NewClass1 with the same value of property Name, for the second one to get an error stating that it violates the unique index.
