Introduction to Django part 2

In the first part, I've shown how to start a new project on Django, as well as define new models and add already existing models.

This time, I'll introduce an admin panel, available out of the box and how it can be useful.

Important note: do not expect that if you try to repeat actions from this post it will work for you, it does not. During the article, I had to do some fixes in the django-iris project, and even in DB-API driver made by InterSystems to fix some issues there as well, and I think this driver is still in development, and we will get more stable driver in future. Let's decide that this article only explains how it could be if we would have all done.

In this article, I am trying to identify the multiple areas to develop the features we can able to do using python and machine learning.

Each hospital is every moment trying to improve its quality of service and efficiency using technology and services.

The healthcare sector is one of the very big and vast areas of service options available and python is one of the best technology for doing machine learning.

In every hospital, humans will come with some feelings, if this feeling will understand using technology is make a chance to provide better service.

Installing Apps without Docker

I was wondering if someone could help me. I do not have docker available to me however a lot of the Open Exchange apps require it. Since I am using a Virtual Windows Machine I can not get docker installed, so I was wondering how to get around this? Someone at GS2022 suggested looking at the docker_compose.yml to figure out how to get around docker, but I am not sure I understand how to read it.

Hi Community!

We’re so glad to announce that InterSystems FHIR startup incubator — Caelestinus held its first virtual Demo Day on June 29th!

16 startups have showed off their products and solutions built with InterSystems FHIR Server, or IRIS for Health or Health Connect to an audience of about 15 investors & partners.

The Demo Day is the result of a four-month journey — the equator of the incubator, in which startups have explored InterSystems tech, validated their ideas and presented it on the first Demo Day. In case you missed it, enjoy watching it on InterSystems Developers YouTube:

📣 The First Demo Day of InterSystems FHIR Startup Incubator — Caelestinus

Here is the list of presenters with pitch decks of the startups.

Healthshare FHIR Subscriptions

Hello All,

Having a recent project to create a FHIR repository, I want to know (as looking at the code) if HealthShare FHIR implementaton supports subscriptions?. I know it records the subscriptions ok, BUT does it handle sending the subscription out (based on the tags) to an endpoint (i.e. when a new FHIR request commits data that would trigger the subscription) ?, I'm 50% it doesn't, but would rather find out for sure before shoe horning something in.

Regards

I am writing documentation in VS Code, using markdown, and am including some COS snippets in it, e.g.:

```objectscript
[Some COS snippet]
```

The IRIS language server (etc.) is enabled, and classes in the repository this documentation is in, are syntax highlighted properly. However, the code fragment in the documentation isn't. Syntax highlighting for e.g. XML does work.

Am I doing something wrong, or is this not supported?

Following this GitHub we will see how the FIX protocol can be implemented easily using IRIS and Python.

If you don't have much time focus on the Send a Quote before the Order part near the end, as it will, in a matter of minute, tell you how to send a Quote Request followed by an Order Request and show you the result from the server, and that in no more than five clicks.

An interesting pattern around unique indices came up recently (in internal discussion re: isc.rest) and I'd like to highlight it for the community.

As a motivating use case: suppose you have a class representing a tree, where each node also has a name, and we want nodes to be unique by name and parent node. We want each root node to have a unique name too. A natural implementation would be:

Showing dates in missing periods

When we collect temporary data (the number of purchases in the store, the number of comments on the post), it may happen that there is no data for a certain period of time. In this case, this time period (hour, day, month) is not represented in the database, that is, there is not a single row for this period. In other words, there are no rows in the database for this period.

In this article, I would like to talk about the spec-first approach to REST API development.

While traditional code-first REST API development goes like this:

  • Writing code
  • REST-enabling it
  • Documenting it (as a REST API)

Spec-first follows the same steps but reverse. We start with a spec, also doubling as documentation, generate a boilerplate REST app from that and finally write some business logic.

This is advantageous because:

  • You always have relevant and useful documentation for external or frontend developers who want to use your REST API
  • Specification created in OAS (Swagger) can be imported into a variety of tools allowing editing, client generation, API Management, Unit Testing and automation or simplification of many other tasks
  • Improved API architecture. In code-first approach, API is developed method by method so a developer can easily lose track of the overall API architecture, however with the spec-first developer is forced to interact with an API from the position if API consumer which usually helps with designing cleaner API architecture
  • Faster development - as all boilerplate code is automatically generated you won't have to write it, all that's left is developing business logic.
  • Faster feedback loops - consumers can get a view of the API immediately and they can easier offer suggestions simply by modifying the spec

Let's develop our API in a spec-first approach!

I have successfully created REST service classes on my local IRIS server following this book: Using the /api/mgmnt/ Service | Creating REST Services | InterSystems IRIS Data Platform 2021.2

I am now 1) trying to edit impl.cls in VS Code and 2) export it to my local repo so I can push to the remote repo.

When I click on my project in VS Code and 'Add to project' and choose the new package, spec.cls and impl.cls, I get the following error:

Hi:

Had an issue after upgrading to 2021.1 where search bar for interoability will bring up "INVALID ACTION".

On upgrading to 2022.1 this still occurs.

It did not occur on another environement that was upgraded from 2017.2 straight to 2022.1

Is there any solution? Loads up SYS in url rather than customnamespacename

Issue is the url for instance brings through ip/csp/sys/EnsPortal.DTLEditor.zen?$NAMESPACE=X

I would say it is a post of pain after years of using InterrSystems IRIS Docker images in many projects.

And I hope InterSystems will hear me and do something with it.

We have a lot of issues with Docker images, but I see no progress in solving them.

  • containers.intersystems.com - any new releases substitute previous versions, makes build useless
    • ARM64 images have separate names, and it makes a pain to use them
  • flags in iris-main, appears and disappears from version to version, which may fail the start the container
  • healthcheck does not work as expected
