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.
On a persistent class, I have defined an %OnNew method that validate some properties with appropriate status code for each kind of error.
Question is: how do you catch the specific error when %New is called on this class?
Surrounding %New method with a try-catch not seems to work.
I am trying to get a list of all settings for all the config items of a given production using SQL . When I run the following sql as a dynamic query I am unable to access the setting names and values. Settings is a list of Ens.Config.Setting
Besides objectscript's own list, array data structure, are there any other data structures that have been implemented, similar to the "collection" package in java, or is there a ready sorting tools for the collection class.
I am trying to figure out the best ObjectScript analog to mimic, more or less, the %RCOPY functionality. What would be ObjectScript method(s) if any to copy a routine from the current namespace to another one and compile it there?
I want to be able to view generated items from visual studio code. In Studio there was an option in the open dialog:
Specifically, I added a namespace to my workspace for editing (Using InterSystems Server Manager) and I want to be able to access the generated items in this namespace.
Let's say I have two lists of connected data where elements of listTwo only make sense if given an item of listOne as context:
listOne = ["A", "B", "C"]
listTwo = ["x", "y", "z"]
Tuples like ("A", "y") and ("C, "x") make sense, but "A" or "x" by themselves don't. I would like to pass in a list of such tuples into a method and have it handle each tuple in the list. So what would be the best way to format them given that ObjectScript does not have specialized tuples? Would it be nested $LISTBUILD lists or something else?
How can I refer to a classmethod of the same class while coding another classmethod with Embedded python?
I know that I can call it with iris.cls(classname).MethodName(), but it's more cumbersome even comparing with ObjectScript, where I can call ..MethodName().
We have a function that was written for us that allows us to create text files for logging certain aspects to the OS using %Stream.FileCharacter. We had no issues with this until we moved from AIX to Red Hat.
Now it seems the 1st time the function is called, and the file is created the permissions seem to be correct on the file. But as soon as we attempt to write another line to the file using MoveToEnd() it seems the permissions are changed on the file. I have been able to narrow the issue down to the MoveToEnd() by calling the function from different users.
I am trying to create a HS.FHIR.DTL.vR4.Model.Resource.Encounter message based on a conversion of HS.FHIRServer.Interop.Response QuickStream to a JSON %Dynamic Object.
When I try to send the HS.FHIR.DTL.vR4.Model.Resource.Encounter onto the Router
Is there a generic process for "walking" the structure of a virtual document - eg an HL7 message (EnsLib.HL7.Message) or an XML document (EnsLib.EDI.XML.Document).
At least we'd want to be able to visit all "nodes" (HL7 fields or sub-fields, XML nodes) in the virtual document and be able to work out/generate the Property Path (so we could call "GetValueAt").
We can just about come up with something generic for HL7, since it only nests down to 4 levels within each segment, though we're using numeric Property Path's at that point rather than symbolic ones (MSH:1.3 etc).
I have some logging code that outputs task status information to a log file. I would like to make the log available for reading while it is open for writing. The file is opened using the "L" option (Lock):
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?
Currently, we are utilizing batch jobs at the OS level to kick off routines that watch for files. We are trying to convert these processes to be performed by the Task Manager.
The routines have while loops and perform while loops so long as the time parameters are being met.
What's the best way to ensure Task Manager kicks them off after the completion of the shutdown/backup/start process is performed, which we do nightly? I want to ensure that it starts it regardless of the time that we've set.
In the documentation it says to set the username and password properties of the connection object but these properties don't exist and without authentication I can't connect to the MQ queue.
I need to automate the handling of usernames passwords, serverNames etc for use in the sending and receiving of emails, logging into SFTP servers etc etc for use within COS code To manage external passwords we could use LastPass or any other proprietary password loggers, but I need to be able to call them as part of the automation (COS code) and occasionally visually look them up to "remind" the staff of their passwords.
any suggestions as to the best class data constructs to handle this scenario. Should the whole table be encrypted, only the passwords etc.
