#ObjectScript

Is there a way to add specific table permissions to a security role programmatically? I'm working on scripting some of the initial setup work when we sell certain add-ons to our software, and I see how I can assign resources to a role and give it a description, but I don't see how I tell it that this role gives the user, for example, SELECT privileges only on the invoices table, or SELECT, INSERT, UPDATE, and DELETE.

Hi Community ,

Can anyone please explain how to use EnsLib.EMail.AlertOperation operation to send notification to my email id when any error occurs in my production?

Please give any example how to use EnsLib.EMail.AlertOperation operation class

Thanks,

The topic of for/while loop performance in Caché ObjectScript came up in discussion recently, and I'd like to share some thoughts/best practices with the rest of the community. While this is a basic topic in itself, it's easy to overlook the performance implications of otherwise-reasonable approaches. In short, loops iterating over $ListBuild lists with $ListNext or over a local array with $Order are the fastest options.

As a motivating example, we will consider looping over the pieces of a comma-delimited string.

Hello 

I have a class to render reports as  pdf. My problem that arabic characters in report replaced with ####. 

Please find my code below

#dim stream as %Stream.Object set report = $classmethod($piece(reportClass, ".cls"), "%New")
set report.RUID = RUID set %response.ContentType = "application/pdf"

set sc = report.GenerateReportToStream(.stream, 2) return:$$$ISERR(sc) sc
do stream.OutputToDevice()

return $$$OK

Your help is appreciated.

Hello all; I am using a one-to-many relationship.  I have a Claim (one), in a relationship with Lines (many), but the Claim is storing a list of Lines IDs, rather than the Lines storing the Claim Id.  This seems upside down, and not what I expected.

Class Claim

{
    Relationship ClaimLineRel as ClaimLine [Cardinality = many, Inverse = Claim];
}

Class ClaimLine
{
    Relationship Claim as Claim [ Cardinality = one, Inverse = ClaimLineRel, OnDelete = cascade];
    Index ClaimIndex on Claim;
}

But the storage globals for Claim show data in the ClaimLine spot:

^ClaimD(1)=$lb("",$lb(2,3).

A small reflection/question for today... it's true that new IRIS for Health (I4H) releases are more and more powerful each time regarding FHIR capabilities. Nowadays it allows us to consume FHIR resources with extrem easiness, we can connect with end-points in external FHIR servers very easily and make I4H act as passthrough or consume their resources... or, even more, we can define, configure and run a FHIR repository in, literally, less than 5 minutes.

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

MSH| ^~\&|||||20221014103828.043+0100||ACK^A03^ACK|1049|D|2.5.

Hi ,

Still a newbie for ensemble, I am trying to convert XML message to HL7 Message. I am using Custom schema for XML structure which includes MSH and PID segments from HL7 Message.

These are the service, process, Operation classes i am using 

Business service-EnsLib.EDI.XML.Service.FileService

Business Process-EnsLib.MsgRouter.RoutingEngine

Business operation -EnsLib.HL7.Operation.FileOperation

I am using data transformation to convert XML message to HL7 message  and data transformation is working fine and im getting this in the business operation.

Good men don’t need rules.

With $Property is possible to dynamically get and set values on property of an instanced class and with $ClassMethod is possible to invoke methods from a class. I would like to know: Is there an elegant way to do Write and Set dynamically on variables without using Xecute?

Hi everyone,

I'm having trouble parsing XML containing unicode characters which I receive from an external webservice. I believe my file is saved properly with UTF-8 encoding but the SAX Parser still throws me an error.

I have 2 classmethods: 1 general one (get) to make a request to a webservice and return the date, and 1 (getSportsPerDate) to make a specific call and then parse the data.

ClassMethod getSportsPerDate(language As %String, date As %String)
{
    #dim cResponse As betradar.uof.api.descriptions.schedule.scheduleEndpoint
    #dim res As %Stream.FileCharacter

    s res=.

Hi, devs!

Consider you have an arbitrary global with an unknown amount of indexes.

How to print all the values to the terminal with Embedded Python?

Hi folks!

I'm working with a global via Embedded Python as a class method. I init the handler for a global via:

gl=iris.gref("^Global")

What is the way to check the value at index ^Global("x","y")? E.g.:

In ObjectScript I'd do the following:

set result=$data(^Global("x","y"))

How do I do the same in Embedded Python?

I checked the documentation, but haven't found an answer.

Issue

Breakpoints do not work when using VS Code Debug this method feature on a ClassMethod. Debug runs like normal and I can sometimes see 'running' on the CALL STACK menu. In the BREAKPOINTS menu, the breakpoints will start red, like normal, but eventually turn gray. On-hover for a grey breakpoint is the message "Breakpoint Cannot Be Mapped". After the method finishes, the breakpoint turns red again. No error messages appear. This is an intermittent issue, as sometimes it runs fine. So far, I have not been able to figure out the conditions to re-create this issue.

Any suggestions?

If your handling XML then it can often be unformatted for human display.

Using a little bit of XSLT magic you can format the XML in just two lines of code...

When using VS Code for Objectscript, is there a way to directly open % classes, like %Library.String, without needing to search for a property of that type and right clicking->"Go to Definition"?

I know it is possible to use "system=1" in the workspace uri definition to see all the % classes, but that tends to clog up the left side viewer with many extra directories. There is also the option in the settings to selectively hide some by defining files.exclude, but it seems fairly complicated to set up a filter for exactly the relevant directories.

So does anyone know the best workaround?

Hi, ObjectScript experts!

I know that there are auto-generated getter and setter methods for class properties in ObjectScript.

Are there auto-generated getter methods for class parameters?

Hi folks!

We have a bunch of templates on OEX that provide a handy foundation for building a particular application with IRIS.  And the basic principle of each and every template is that we take vanilla IRIS images, load code, and files into the image using Dockerfile, and create a new docker image as a solution. And then we develop running this image and rebuilding it when returning to development.

Some developers ask me why we need to build the docker image to work with the code. Indeed, if at the end of the day I need to develop a ZPM package and not a docker image why don't run the vanilla image and load the code and everything in it? 

The problem I have with the building image approach is that often I can wait a lot to build an image and it fails on some Objectscript problem in the source that I cannot fix as the image is not building. and 

Any thoughts? How do you develop with docker?

Let's consider these two ways of passing an obj to a function:

//var is a structured obj
(1) do ..methodX(var)
(2) do ..methodX(.var)

In c++ if we pass an obj by reference like in (2) we save a lot in computation because we are not copying the whole object, and when the object is modified within the function it is modified also for everyone.

In this case does (2) achieve any better performance than (1)? Is passing with the "." save any computation? the object is copied anyway?

Is there a simple way of passing obj to a function?

 Hello Community!

This article gives an overview of the REST JSON webservices developed for TrakCare.

These webservices allow users to access TrakCare data from outside of the software, mainly through external apps.

Hello,

I need to run some clean up routine in the background so loss of my terminal session won't stop the process.

I found the JOB command in the documentation.
JOB | ObjectScript Reference | InterSystems IRIS Data Platform 2022.1
When I try it, it doesn't seem to be doing much. I also expected this to become visible in the Background Tasks but that doesn't happen either.

Probably I am missing something.

This is the command I am running:
JOB ##class(HIHLib.Support.GetHL7MessageStat).ISBListingQuery("2017-01-01","2017-02-01",0,"WAHISCL",-1,0)::10

The same command without the ::10 has the same effect.

Is it possible to use integer with a higher precision so that something like this works:

ClassMethod BigNumbers()
{
    Set bigInt1 = 9223372036854775807
    Set bigInt2 = 9223372036854775808
    W !,bigInt1
    W !,bigInt2

    Set bigInt3 = 9223372036854775807123456789
    W !,(bigInt3 # 2)
}

9223372036854775807
9223372036854775810   // should be 9223372036854775808
0                     // should be 1

The docs say ". However, with extremely large numbers (larger than 9223372036854775807E127) it is not always possible to convert a numeric string to a Decimal value.
