Hi, Community!

I'm pleased to announce that we deployed a new release of Developer Community.

This release comes with improved Search.

The updated search feature introduces full-text scan, auto complete for the key words, filters on articles, questions, comments, members and works faster.

Here is the small video on how it works.

Also, we fixed a few bugs and made DC faster.

Hope you like it! 

Stay tuned for the next release and introduce your issues here in comments or and enhancement requests and other issues in the DC Feedback group!

Hi, folks!

There is an interesting discussion in the neighboring topic which raises a question for me: is there any reason to have %Status as a return value for COS method?

Hi, Community!

Due to increasing number of new questions and articles regarding containerization, docker, microservices we've introduced certain tags. Subscribe and use it in your postings.

If you have any ideas for new tags to be introduced, please add your ideas in comments.

Hi, folks!

Suppose I have a CSP app, which provides some service.

And the code of my App knows the name of the CSP App in form: /myappname

How can I programmatically obtain the URL for CSP apps to send the full qualified link to the users(e.g. via email) of my app?

E.g. https://productionserver.com/myappname

Hi, Community!

Recently we announced Developer Community Meetup in Cambridge, MA. Let me describe what is it. 

Meetup it's a one evening event where you can enjoy some sessions by presenters (today InterSystems engineers, tomorrow you can be a presenter) and chat with local developers and InterSystems developers, engineers and product managers (depends on who is in town) and discuss your problems, experience, and success with InterSystems technologies.

InterSystems would provide the place, technical sessions, some food and beverages. 

We think the Developer Community would benefit from it.

Hi, Community!

We introduced the new dashboard which shows the stats on members' articles, questions, and answers.

Hope it would help you to find the authors you would like to follow and find interesting posts you could miss.

Hi, Community!

How do you store the source files of your Caché project? What is the directories structure? What are the benefits?

I prefer the following structure:

/cls/package/subpackage/class.cls

/mac/package/routine.mac

/int/package/routine.int

/inc/macro.inc

/dfi/folder/sample.pivot.dfi

Example

Benefits: 

• folders are packages.
• easy to understand what type of sources are in the project.

What is your approach?

Hi, Community!

Hi, Community!

Suppose I have class A with properties P1 and P2.

I want to introduce class B, which would have same records as Class A, but only  one property - P2.

What is the easiest  way to manage it assuming that I would like to use Class A to add records and be available for any operations to Users with Role A.

And I would like to introduce class B for Users with role B for read-only access.  Preferably they shouldn't even be aware of Class A and P1 existence .

What is the easiest way to introduce it and manage it?

Use some proxy-classes?  Property-level security?

Or to Introduce usual class B

Hi, colleagues!

Consider you need to put some (less  than 1GB) data to an indexed array and do some data manipulations and calculations with it.

Should I prefer global or local for it?

Is there any general rule when local is faster than global and vice-versa?

Check the new video on Developer Community YouTube Channel:

Hi!

I'm saving object instance using RestForms.

RESTFormsUI calls %Save() for me, which is great. But I want to set the property CreationDate with the current date for every new record being inserted.

So  object callback implementation seems as a reasonable option. I did the following:

Method %OnBeforeSave(insert as %Boolean) As %Status [ Private, ServerOnly = 1 ] 
{

 if insert s ..CreationDate=$H

 q $$$OK

}

And it works fine.

But Documentation says I'd better use %OnAddToSaveSet()

What are you using for the callbacks in similar cases?

Hi, colleagues!

When you export the Caché ObjectScript code to VCS (Git, SVN, Perforce, etc) do you export the Storage schema for persistent classes?  If so, what are the Pro/Contra?

Thanks!

Hi, Community!

We have a lot of good articles posted on Community to the date. Even more questions with great answers (see the stats). Thank you for your contribution!

So sometimes it worth to use search to find an answer or the best practices or the post you remember was posted but cannot find. 

Hi, colleagues!

Suppose you have large set of cubes, pivots and dashboards in your DeepSee solution.

Then you  change the level, measure or dimension in the cube and is there any way to test that your new input didn't  break current pivots, dashboards, etc?

How to test this?

How do you test your DeepSee solutions?

We are having some troubles with post duplicates at the moment, we are working on it.

Now when you post your message it waits until timeout and shows 404  but also publishes the article.

Hi, Community!

We are starting  InterSystems Developer Community meetups:  events to discuss InterSystems technology in person.
