Does anyone know what this task does exactly? And what problems would I have if I didn't use an SSL certificate?
I got the error: "SSL/TLS error in SSL_connect(), SSL_ERROR_SSL: protocol error, error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed"
Has anyone encountered this problem before?
In the next few weeks, my coworkers are planning to start using VSCode to code with InterSystems' products. Among the many advantages of that, I would emphasize being able to connect with other technologies, such as GitHub, with ease. Besides, VSCode also offers an extensive extensions store, where you can find many free add-ons that make coding faster and more efficient. Last but not least, to conquer the heart of every developer, it is open source.
With that being said, let's start the tutorial. Feel free to skip some steps if you're comfortable doing them alone.
Not so long ago, I came across the idea of using Python Class Definition Syntax to create IRIS classes on the InterSystems Ideas Portal. It caught my attention since integrating as many syntaxes as possible gives visibility to InterSystems’s products for programmers with experience in many languages.
The author of that idea pointed out the possibility of creating classes using Python’s syntax, in addition to the currently available ones on IRIS. This concept inspired me to write this article, exploring the possibilities of accessing the full InterSystems power employing only Python.
When I do $TRACE("message") I can see the message on the message viewer. However, I don't know where to find messages generated from $$$sysTRACE, and I haven't found anything about it in the documentation.
Do you know where I can find it?
This app offers an easy interface to analyze storage:
Follow the instructions on the README file from the GitHub repository, and configure the settings to connect to your instance.
Since it was built with Python and Django, you can easily add specific analysis methods in the api/methods.py and use the views on views.py to display them.
Today we continue expanding our last article by sharing information about some features we added to our portal. We will include a pinch of CSS to visualize the available data better and export it. Finally, we will study how to add some filtering and ordering options. By the end of this article, you should be able to display a complete simple query beautifully.
Introducing Django
Django is a web framework designed to develop servers and APIs, and deal with databases in a fast, scalable, and secure way. To assure that, Django provides tools not only to create the skeleton of the code but also to update it without worries. It allows developers to see changes almost live, correct mistakes with the debug tool, and treat security with ease.
To understand how Django works, let’s take a look at the image:
Being a programmer nowadays is basically the geek version of being a polyglot. Of course, most of us here, in the InterSystems Community, “speak ObjectScript”. Howeever, I believe this wasn’t the first language for many people. For instance, I had never heard about it prior to getting the appropriate training at Innovatium.
In my last article I've talked about returning values with Python. But returning them is simple, what can make it harder is what I'm going to talk about today: where the value is treated.
Following the example of the last aricle, we have the method:
Class python.returnTest [ Abstract ]
{
ClassMethod returnSomething(pValue... As%String) As%Integer [ Language = python ]
{
return pValue
}
}
Then, we'll have as a return a Python object, that IRIS interprets as the class %SYS.Python. So if I call the method with two values, like this:
This article is intended to be a simple tutorial on how to create ODBC connections and working with them, since I found starting with them a little bit confused, but I had amazing people to take my hand and walk me through it, and I think everyone deserves that kind of help too.
I'm going to divide each little part in sections, so feel free to jump to the one you feel the need to, although I recommend reading everything.
I'm going to use the sample data created in a previous article, Quick sample database tutorial: Samples.PersistentData, with the properties Name and Age.
In some of the last few articles I've talked about types between IRIS and Python, and it is clear that it's not that easy to access objects from one side at another.
Fortunately, work has already been done to create SQLAlchemy-iris (follow the link to see it on Open Exchange), which makes everything much easier for Python to access IRIS' objects, and I'm going to show the starters for that.
Thank you @Dmitry Maslennikov !
To install, simply open your terminal with administrators' access and type
pip install sqlalchemy-irisThis is a simple tutorial on the quickest way I found to create a sample database for any purposes such as testing, making samples for tutorials, etc.
Now you have a new namespace in a faster way than creating it from the Management Portal - which of course offers way more configuration options.
Once again I had a challenge that costed me some time and a lot of testing to reach the best solution. And now that I've managed to solve it, I'd like to share a little bit of my knowledge.
In a namespace there were a lot of similar classes, so to make them simpler there were a superclass with comon properties. Also, there are relationships between them. I had to export one of them to JSON, but I couldn't change the superclasses, or I would break down the flow of many other integrations.
Last year I made an article for starters on using embedded python. Later, it started a little discussion on how to return values with python and I found some interesting observations that are worth writing a little article. Also, hopefully I can reach more people by writing this.
There are two things you'll need to care about when returning a value with python. The first is the type you're trying to return and the second is where you're returning it.
Recently I had the challenge to create a secure authentication method to authorize access to some data, but unfortunately I had zero experience with those security configurations and I felt that I was missing some basic concepts to have a better understanding of the official documentation.
After studying and managing to deliver the classes that I was asked to develop, I'd like to share a little bit of my new knowledge, which helped me follow the topics in the documentation.
Here you'll find a simple program that uses Python in an IRIS environment and another simple program that uses ObjectScript in a Python environment. Also, I'd like to share a few of the troubles I went trough while learning to implement this.
Let's say, for example, you're in an IRIS environment and you want to solve a problem that you find easy, or more efficient with Python.
You can simply change the environment: create your method as any other, and in the end of it's name and specifications, you add [ Language = python ]:
I recently started to study interoperability and I found the official documentation very helpful in understanding how it works, though I still had some trouble implementing it myself. With the help I got from my coworkers, I managed to create a Demo of a system and learn through practice. Because of that, I decided to write this to help others with "getting their hands dirty" and share the help I got.
