#InterSystems IRIS

Hey Developers,

New demo show by InterSystems Product Manager @Raj Singh is already on InterSystems Developers YouTube:

What is npm-iris?

N.P.M stands for "No Project Mess."

N.P.M. is a Project & Task Management app that uses InterSystems IRIS and Bootstrap 4.

No Project Mess is created to help developers and small business companies to reduce complexity in their daily problems, with a simple and intuitive projects and tasks management software.

It offers different views for your tasks, from a spreadsheet, kanban, calendar, or even Gantt!

I'm not sure how to go about building this scenario:

Hi Developers!

Hi developers!

Want to discuss with you the case of %Status.

If you familiar with ObjectScript you know what is it. I'd love to hear the history of the case why it had appeared in ObjectScript but it turned out that almost every system/library classmethods return %Status and there is a whole set of tools to deal with it.

What is does it gives you the responsibility to check the value or %Status of every system method you call.

E.g. if you save the data of the persistent class, you should never call like this:

do obj.%Save()

you need to call:

set sc=obj.%Save()

if $$$ISERR(sc) do // something or quit.

Hi Developers!

How do you handle errors with &sql a.k.a. embedded SQL?
I think I found a universal error-handling template which works in any situation:

&sql(SELECT * FROM Sample.Person)

if SQLCODE < 0 throw ##class(%Exception.SQL).CreateFromSQLCODE(SQLCODE,"Context description")

What is your choice?

In the WRC, we frequently see customers contact us because their Web Gateway is unable to serve web pages. This article will explain a frequent reason why these errors can occur, and explain some tools which can be used to debug the problem. This explanation is focused on the Web Gateway serving InterSystems IRIS instances, but the same explanation should apply to the CSP Gateway serving Caché instances as well.

Hi Developers!

Recently we discussed the naming convention on packages we deploy and even made some choices.

Here I want to have a conversation on the naming convention for unit tests.

Of course, we wish every good library has unit tests. Here is the documentation and some good articles(one, two, three) regarding it on the Developer Community.

Let's decide on the naming of UnitTests packages?

The suggestion is that unit test classes will all start with the UnitTest package name.

E.g. if your library's class name is:

johndoe.lib.class

The related unit test class will be:

UnitTest.johndoe.lib.class

What about folders?

The suggestion is that unit test classes will live separately from source classes, e.g. in /tests directory.

Here is the example of a repository with unit tests that are named and placed according to the proposal.

What do you think?

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?

No reason apparently,

to many times executed :

[Database.SparseDBExpansion] Expanding capacity of sparse database /usr/irissys/mgr/iristemp/ by 1000 MB.

no details on audits, no traffic for that, no process to justify this, some ideas ?

IRIS for UNIX (Red Hat Enterprise Linux for x86-64) 2020.1 (Build 215U) Mon Mar 30 2020 20:23:13 EDT

Hi Community!

We are pleased to invite all the developers to the upcoming InterSystems Full Stack Contest Kick-off Webinar! The topic of this webinar is dedicated to the Full Stack Contest.

On this webinar, we’ll demo the IRIS Full Stack template and answer the questions on how to develop, build and deploy full stack applications in InterSystems IRIS.

Date & Time: Monday, September 21 — 11:00 AM EDT

Speakers:
🗣 @Evgeny Shvarov, InterSystems Developer Ecosystem Manager
🗣 @Raj Singh, InterSystems Product Manager - Developer Experience

Dear Folks,

I am looking for a native approach to call a ClassMethod of an instance from another instance (Instances are running in different servers). I can still do this via API over Http or any other communication method but I believe it would be better if I communicate via IRIS native methods(If exists).

Thanks

Hi,
I'm looking for a way to run ZPM (especially install) in a total silent mode with no output.

I tried -quiet flag but it continues to chat to me like my wife.

The demo is based on the raw class descriptions.
The data classes used are Address, Person, Employee, Company
For a more attractive demo, a JSONtoString method by ID was added.
