InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
This discussion is open to anyone who use or know about WebTerminal project. It is a result of a long story of the project development, testing and maintaining.
Here's my issue. I've been using Sample.* globals and packages mapped to another development namespace to realize unit tests. So when I ran it, I notice that I forgot to start a transaction in order to be able rollback it to it's original data.
I assumed that I should use transactions since I was manipulating it's data but I didn't want it to be persisted.
I have a case where I am creating a PDF file from an Encoded String, and I need to transfer this file over to another server. I was wondering since this is PDF file if I could just invoke the FTP.OutboundAdapter within my Object script that is creating the PDF from the encoded string. Is this possible? Does anyone have an examples of using EnsLib.FTP.OutboundAdpater within their Object Script?
Last weekend we held the Final of InterSystems Contest on InterSystems Caché and DeepSee as a part of IT Planet Student Championship in Sochi. BTW, this year we had about 2 000 participants in InterSystems Contest.
I'm doing a REST service for integration between 2 systems. The system that invokes me expects a response object where only one of its attributes changes. It could be something like this:
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:
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?
This is a translation of the following article. Thanks @Evgeny Shvarov for the help in translation.
Let's assume that you wrote a program that shows "Hello World!", for example:
write "Hello, World!"
The program works and everyone is happy.
With time, however, your program becomes more complex, gets more features and you eventually need to show the same string in different languages. Moreover you don't know the number and names of these languages.
The spoiler below contains a description of how the task of multi-language localization is solved in Caché.
Looking for a way in which I could possibly pass a flag through a property when performing an Insert statement, on a mapped class.
insert into my.class (serialNumber, modelNumber, myFlag) value ('testSerial', 'testModel', 0) myFlag is not stored in the DB.
The mapped class then calls a legacy routine (MAC) via CodeMode = 'objectgenerator', (Insert method within the 'objectgenerator')
Within the legacy routine, I am setting an index... but I don't always want to set it (multiple inserts, and I will only set the index on the LAST insert)
Say you have a global in one database that you instead want to map from a different database. If you just create a global mapping to the new database, the existing global will become inaccessible because it still lives on the old database. The documentation notes this problem here but doesn't give details on how to fix it.
On the back of my recent post on writing bug-less code I wanted to raise a few suggestions (to ISC) that would help prevent certain types of bugs at compile time. I've probably missed a few, but these are the main ones in my mind. Please contribute more suggestions.
Btw, these also serve as potential gotchas for new COS developers.
Cache Studio almost always crashes when I click rows in Call Stack view during debugging. Then Cache has to be restarted because last edited file remains locked.
Looks like I'm the only one who uses the debugger. Or is there a magic spell to make stack view working?
I have classes A and B, B derived from A, A has method Abc.
From INT of class B I see that compiler copies implementation of Abc to class B, so that Abc exists both in A and B.
As result, when B invokes Abs, B.Abs() is executed instead of A.Abs(). In result debuger is not able to step into Abs and breakpoints in A.Abs never hit.
Why this happens and how can I avoid this?
Update:
OK, now I know the reason: compiler makes the copy if Abc has this line:
With help from others here I had developed some code to take a Base64 PDF within a OBX.5 and save it locally to the file structure on the server.
I had to make a change to the code to return me a String so I can pass the Path back into Ensemble to use it in the message. When I made this change I am getting " ERROR #5034: Invalid status code structure ("/ensemble/data/transfer/AncillaryPDF/TMSAUDIO/Apr-11-1/980512729TMSAUDIO1046784936436537800.pdf")"
In case of system exception (missing property, method etc) Cache Studio's debugger stops at the line throwing it. Unless the line is in try/catch block.
Is there a way to make it break also in try/catch case?
There is a large file that needs to be processed, with over 500 000 rows. Each row needs to be verified for various data and then all the results collated and reported into a single report. What is the most efficient way to do this? I tried calling the processing function with Job , where each function jobbed off would report results to a different node of a common global. But the jobbed functions are not updating their respective rows even though I am passing the global name and root node. What is the most efficient way to process this large file?
Hi All,I got an error when i compile one class. the error was objects of class are (classname) instantiated in 1 processes.how can i recover the problem. my cache instance is Cache 5.0
