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.
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?
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)
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?
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?
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?
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")"
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
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:
Hello, we have a few hundreds of triggers to port from Oracle to Cachè for a migration project, and many of them have to change (for example, normalize a value, null it, etc) the value which is being inserted.
The documentation says "You cannot set {fieldname*N} in trigger code." , so we're unlucky.
Is there a good workaround for this ?
SqlComputeOnChange doesn't seem the best way, but I'm not totally sure: for example normalization and validation could have a better place somewhere else than a trigger.
We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS. One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.
In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?
Let's say I have two classes: A and B. They share no common parent except %SystemBase. But these classes have some properties with the same name (type may be the same or not):
Class A {
Property data As C;
Property data2;
}
Class B {
Property data As D;
Property data3;
}
I need to automatically convert object of class A into object of class B. I'm planing to write a class generator that generates a separate class that converts A to B. It would work like this:
I have a number of Business Process and due to the complexity these were created as "custom code" instead of BPL.
These processes currently invoke other components using SendRequestSync. For a couple of reasons I would like to be able to change these to use SendRequestAsync:
