While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together.

1. Working with Dynamic Objects:

Hi fellow developers!

Curious if you guys use CreatedAt and LastUpdated properties in your classes?

Created to stamp when the record was created and LastUpdated when it was last updated. Where it can be useful - almost everywhere )) I find it convenient in records sorting (e.g. by creation or last update), in sync (with other systems), and so on, for better analytics.

Do you use it all the time for all the classes?

If don't, why not? What do you use instead?

What property type do you use - %TimeStamp? %DateTime?

What is the best practice to have CreatedAt filled automatically during creation and LastUpdated on every successful save (guess it could be in %OnSave)?

Please share your experience /thoughts?

Request LDAP

Hello,

I need to make an LDAP query to retrieve information about a specific team of employees. I have a custom service that instantiates a message of type EnsLib.LDAP.Message.Search with a filter matching the search and redirects it to an operation of type EnsLib.LDAP.Operation.Standard. I didn't get any errors, but I didn't get any results either. So I created an operation that inherits from EnsLib.LDAP.Operation.Standard and I overloaded the method to retrieve something. I get this:

Hey Developers,

Watch this video to learn how an InterSystems partner based in Ostfildern, Germany, made a simple switch to InterSystems IRIS and rolled it out to 2,500 end-users by using the in-place conversion:

Hi there,

I want to use regex in my code, and I saw that the %Regex.Matcher class contains a property "OperationLimit" that you can also set to a number of steps that the regex engine should take maximum in analysing a given string. So far so good.

I tried to set the property with the function OperationLimitSet() to a silly value like 3. In 3 steps only very few regex should be executed, right? But what I found is that my regex always comes up with a solution. Here is what I did:

First I initialised my %Regex.Matcher.

Hi -- at a customer site we have 8 Access Gateways, with a couple of different load balancers that decide which projects go to which subset of AGs.

We're about to go live with a project that uses a subscription, and we have that subscription pointing to one of the AGs. What if that AG goes down? The project is dead until the AG is back up. The subscription forces us to pick an AG that's registered in the Gateway Registry -- I don't see a way to get a cluster or load balancer address in there.

When posting content there's got to be a better way to insert a screen shot. Saving to a file and then uploading is very primative plus the content isn't display in-line as one would expect these days. I don't want to "view a document" I want to see the image in-line.

Confluence does a really good job with this. Can we emulate this behavior?

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

Dynamic Objects

Dynamic Objects are very similar to the standard ObjectScript object model you get when you create a new instance of a class object, but with some key differences:

Namespace vs database

I'm confused about the differences between a namespace and a database.

I understand that a database is a single IRIS.DATA file in a directory in the os hosting IRIS.

What is the difference between a namespace and a database?

Can I write data into a database without specifying a namespace?
If so how do I write to a particlar DB in objectscript?

Does a database have to be in a namespace?
Can a database be in more than one namespace?

Can a namespace have only one 'routine' database and only one 'data' database?

Integrate with Google Forms

Google Forms is the most popular solution on the market for collecting data, answering questionnaires and quizzes. So, it is the ideal solution for collecting patient data and responses in a practical way, without the need to expand or develop systems. In this article, I will detail how to create an account on Google Cloud, register the application that will consume the Google Forms API, generate the service user necessary to consume the API and finally perform actions to create new forms and collect data filled in them in an automated way in embedded Python and IRIS.

Hello,

Is there a single ObjectScript operator or method to concatenate two %DynamicArrays?

I'm looking for something that will do the following:

set arr1 = [ 1, 2, 3 ]
set arr2 = [ 4, 5, 6 ]
set arrcombined = arr1.%Concatenate(arr2)

or 

set arrcombined arr1_arr2

With end result:

zw arrcombined
arr1=[1,2,3,4,5,6]  ; <DYNAMIC ARRAY>

I can iterate and %Pop over the 2nd array and %Push each popped entry to the 1st array, but I was looking for something more succinct.

Thanks in advance.

What is the reason for

RUN apt-get update && apt-get install -y \
git \
nano \
python3-opencv \
sudo && \
/bin/echo -e ${ISC_PACKAGE_MGRUSER}\\tALL=\(ALL\)\\tNOPASSWD: ALL >> /etc/sudoers && \
sudo -u ${ISC_PACKAGE_MGRUSER} sudo echo enabled passwordless sudo-ing for ${ISC_PACKAGE_MGRUSER}

I think I get error because I do not have sudo privilege in the environment where I use podman to build the image

podman build --tag oliver3 .
