Hi Community,


In this article, I will introduce Python Flask Web Framework. Together we will create a minimal web application to connect to IRIS and get data from it.

Below you can find the steps we will need to follow:

  • Step 1 : Introduction to Python Flask Web Framework
  • Step 2 : Installation of Flask module
  • Step 3 : Creation of web application using Flask
  • Step 4 : Use of HTML Templates 
  • Step 5 : Installation of IRIS Python Native module
  • Step 6 : Establishment of a connection with IRIS 
  • Step 7 : Transferring data from IRIS to Flask and displaying it

So Let's start with step 1

Step1-Introduction to Python Flask Web Framework 

Flask is a small and lightweight Python web framework that provides useful tools and features that make creating web applications in Python easier. It gives developers flexibility and is a more accessible framework for new developers since it allows to build a web application quickly using only a single Python file. Flask is also extensible and doesn’t requires a particular directory structure or complicated boilerplate code before getting started.

Linux and links

If I create a link does root use it? (it’s in profile.d dir)

I'm trying to use a shortcut for a filepath as such: anyone have any thoughts?

PROCAUTO  = /JRNDSK/ProcAuto_share

yet in the application it isn't recognizing it.

Here’s the scenario. (link is in place) that my manager thinks maybe an issue.

Basic Database Metrics example

This is a self contained class that can be run from the Intersystems Task Scheduler which records peak usage details for databases and licenses built up throughout the day and retaining 30 days history.

To schedule the task to run every hour:  

d ##class(Metrics.Task).Schedule()

You can also specify your own start time, stop time, and run interval:

d ##class(Metrics.Task).Schedule(startTime, stopTime, intervalMins)

Metrics are stored in ^Metrics in the namespace that the class resides in/is run from.

Hi -

I'm looking for some help in getting an OS level application on my server to startup from a csp page and I'm just missing something.

I have a routine (and I've tried the same code from an instance method, with the same results) that will launch an application at the OS level using the $zf(-100,keywords,program,parms) from a terminal session, but it won't/doesn't seem to work when I call the code from a #server() call from my webpage. I don't know if there is some combination of keywords or perhaps a different version of the $zf() call that should/would work.

Hi Friends,

In my production already we have business components (business service , process, operations) and all are working fine.

Now I have change the package structure of few classes and want to update the references in settings for Business components in Management portal.

As this class field is read only , Any other way to update the class reference, instead of creating new business component?

Decoding Base64 PDF File

Hello, I am writing some cache code that will pick up a PDF file, Base64 encode the contents and then send on to a third party system within a Long String (via their API). I have been testing this and discovered that the PDFs do not open within the supplier system (I get an error saying that it hasn't been decoded correctly). I wanted to prove that the issue does not lie with the way that I have Base64 encoded it within Ensemble, and therefore as a test wanted to Encode the PDF stream, then decode the stream and write out to a new file.

Let's consider these two ways of passing an obj to a function:

//var is a structured obj
(1) do ..methodX(var)
(2) do ..methodX(.var)

In c++ if we pass an obj by reference like in (2) we save a lot in computation because we are not copying the whole object, and when the object is modified within the function it is modified also for everyone.

In this case does (2) achieve any better performance than (1)? Is passing with the "." save any computation? the object is copied anyway?

Is there a simple way of passing obj to a function?

I am trying to pull the status of operations in health connect. I'm successfully pulling if it's enabled/disabled, but I'm not getting access to where the current item status is held (for example, items in error). I found "##class(EnsPortal.Utils).ItemStatuses", but I can't retrieve data from that. Is this data readily accessible via another means?

Thank you!

Hello All,

I have a class method on the DocRepo server that needs to query the data value of a global variable on the Edge server. 

I have looked at the documentation for 'Global Structure,' but I didn't find anything that helped.

Global Structure | Using Globals | InterSystems IRIS Data Platform 2022.1
 

I am able to access this global easily from the Edge server using the $Get function, but I need to access it from the DocRepo server.

Hi All

I'm building a ZEN page that will dispay HL7 from a database, and am currently displaying it an textarea.

 Is the HL7 viewer that is displayed when HL7 message is selected in a visual trace available as an out of the box tool I can plug into a webpage?

If the parameter has more than 50 characters of the error.

Credentials for a Productions are stored as plain text in ^Ens.SecondaryData.Password and exposed as plain text via SQL table Ens_Config.Credentials which is not ideal as only admins should know the credentials.

I can create my own adapter etc... to store and use encrypted passwords but does anyone know if there is a standard way to do this in a Production?

Alternatively, am I missing how to secure this so the production can run and someone can monitor and operate a production without access to the SQL table or global?
