#InterSystems IRIS

Hi

I want to download the iris-facial-recognition application but the download link returns an HTTP 404 error.

Any ideas why?

Given the following requirements about a WebSocket client:

• Start with the production automatically
• Try to re-establish a lost connection periodically
• Send an Ens.Request to another production item when a message is received from the WebSocket server

Where in the production does the WebSocket client need to live?

Hello developers!

Share the best practices: 1) saving frequently used code sections, 2) quickly finding it, and 3) quickly including it into the current program?
There was a thought for 1,2 to use DC(this resource), but the search is not always convenient not only for me

The idea on the surface is to use the git repos wiki.
Are there any other best practices?

What is the correct data type for decimal numbers precision 5?

I tried %Numeric with Scale 5, but not worked, see:

Hi !

I'm looking for a simple way to store in a string a list in $lb representation. Ex :

Set list = $ListBuild("data2", "data2", "data3")
ZWrite list
/* show : list=$lb("data1","data2","data3") */

With the ZWrite command, we can display the $lb representation but I would like to store it in a string variable.

Consider a Natural Key with an Identity (Serial) field.

I cannot seem to acquire the generated value after persisting my entity. That is, the returned entity by Spring Data's "save" does not have the generated value.

The value is generated by the database, and I can query it after repository.save(entity).

I have done some testing and created a Github repo with it...

So I've got the IRIS AMI spun up in AWS EC2; it seems to be running fine.

I've added an EBS volume to it for persistent storage, and now I'm pondering how to make it actually do something useful.

What's the best way to do deploy code to this instance? I can think of a few ways to do it, but what's the least painful way? Push my code to an S3 bucket and figure out how to load it at system start? Github project?

I copied a 5 MB messages.log file to AWS where I have iris-log-viewer app deployed. I ran the test to see how it takes in IRIS code to import the lines into a persistent table:

IRISAPP>set m5mb="/home/irisowner/irisdev/messages.old_20221231.log"

IRISAPP>

IRISAPP>do ##class(otw.log.irislogreader).Test1(m5mb)
Test1 begins at 02/05/2023 12:49:30
ReadLogLines
/home/irisowner/irisdev/messages.old_20221231.log
Open
Test1 ends at 02/05/2023 12:49:34
Test1 execution time: 3.500789

select count(*) from otw_log.Log

I need to create a simple REST application.
I`ve created an app:


Also here is a dispatcher class:

Hi,

Our application needs to create system users from a request form.

To use Security classes, it is necessary to have rights to use the %SYS namespace, which is not the case for users who validate requests.

It is not desirable for these users to have this role permanently, so I proceeded as follows:

I created a facade class for the Security.Users, Security.Roles, Security.Resources classes which allows me to log in with an authorized user on the NS %SYS

Here is an example method:

I have a class that inherits from %Library.CachePopulate

I am trying to use IRIS Native API in .NET code I see following code snippet here https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

  IRISReference valueRef = new IRISReference(""); // set inital value to null string
  iris.ClassMethodString("%SomeClass","SomeMethod",valueRef);
  String myString = valueRef.value;               // get the method result

But IRISReference is not available as a type.

I try to compare classic JOIN against implicit JOIN.

It is a simple case. But I am surprised.

I have a requirement which comes down to evaluating two fields, if they are both empty then provide a default value.

If one is empty but the other has a value, then set the empty one to the field with a value.

The screenshots are not the actual fields, I was just using the dtl and fields to prove out the solution.

When I saved and compiled in the Management Portal I got an error, but it still compiled.
