go to post Pietro Di Leo · Apr 18 Hi Stefano, Thank you for your response. Unfortunately, as @Enrico Parisi mentioned, OnFailureTimeout() isn't working as expected. Nevertheless, I managed to solve this issue by using an existing table which logs information about messages sent from the BO, a Business Service and a Business Process to initiate a parallel process alongside my ongoing transmissions.
go to post Pietro Di Leo · Apr 17 Hi Hannah, Thank you for your response. As you mentioned, the 'arrayref()' function is not available in IRIS 2023.1, as I suspected. However, I managed to resolve this issue by developing a custom method to convert a Python dictionary into an ObjectScript dynamic object. I believe it works quite effectively. I'll share the code here for anyone interested: /// This class provides methods for working with embedded Python in various scenarios Class Utility.Python Extends %RegisteredObject { /// ConvertPyDictToDynamicObject recursively converts a Python dictionary to an ObjectScript DynamicObject /// /// Input: /// - PythonDictionary: The Python dictionary to be converted /// /// Output: /// Returns a DynamicObject with similar structure and content of the parsed Python dictionary ClassMethod ConvertPyDictToDynamicObject(PythonDictionary) [ Language = python ] { import iris # This is a recursive function to parse a Python dictionary and convert it into an ObjectScript %DynamicObject # The method takes two parameters: 'data', which represents the current dictionary being parsed, and 'depth', which keeps track of the nesting level of the current data def parse_dictionary_to_dynamic_object(data, depth=0): # Create a new ObjectScript DynamicObject through iris module dynamic_object = iris.cls('%DynamicObject')._New() # If data is a dictionary, iterate through its key-value pairs if isinstance(data, dict): for key, value in data.items(): # Recursively parse the value and set it in the DynamicObject parsed_value = parse_dictionary_to_dynamic_object(value, depth + 1) dynamic_object._Set(key, parsed_value) # If data is a list, create a %DynamicArray and parse each item of the list recursively elif isinstance(data, list): dynamic_array = iris.cls('%DynamicArray')._New() for item in data: parsed_item = parse_dictionary_to_dynamic_object(item, depth) dynamic_array._Push(parsed_item) return dynamic_array # If data is neither a dictionary nor a list, return the data itself else: return data return dynamic_object # Call the recursive parsing function with the input Python dictionary dynamic_object = parse_dictionary_to_dynamic_object(PythonDictionary) # Return the parsed DynamicObject return dynamic_object } } You can easily test this method with complex dictionaries, like the one in the following example: ClassMethod StartTestPyDictConverter() { set dynObj = ##class(Python.MessageBuilder).TestPyDictConverter() w "dynObj tested",! } ClassMethod TestPyDictConverter() [ Language = python ] { import iris data = { "person": { "name": "John Doe", "age": 30, "address": { "street": "123 Main St", "city": "Anytown", "zipcode": "12345" }, "emails": ["john@example.com", "doe@example.com"], "phone_numbers": [ { "type": "home", "number": "123-456-7890" }, { "type": "work", "number": "987-654-3210" } ], "friends": [ { "name": "Alice", "age": 28, "address": { "street": "456 Elm St", "city": "Sometown", "zipcode": "54321" }, "emails": ["alice@example.com"], "phone_numbers": [ { "type": "mobile", "number": "555-555-5555" } ], "pets": [ { "name": "Fluffy", "species": "Cat", "age": 5 }, { "name": "Spot", "species": "Dog", "age": 3 } ] }, { "name": "Bob", "age": 35, "address": { "street": "789 Oak St", "city": "Othertown", "zipcode": "67890" }, "emails": ["bob@example.com"], "phone_numbers": [ { "type": "mobile", "number": "666-666-6666" } ] } ] }, "company": { "name": "Acme Corporation", "address": { "street": "456 Business Ave", "city": "Bigcity", "zipcode": "54321" }, "employees": [ { "name": "Jane Smith", "position": "Manager", "age": 40, "emails": ["jane@example.com"], "phone_numbers": [ { "type": "work", "number": "222-222-2222" } ] }, { "name": "Sam Johnson", "position": "Developer", "age": 35, "emails": ["sam@example.com"], "phone_numbers": [ { "type": "work", "number": "333-333-3333" } ] } ] } } dynObj = iris.cls('Utility.Python').ConvertPyDictToDynamicObject(data) return dynObj } I've tested it even with more complex dictionaries, like FHIR JSON, and it worked fine. For example, this is a screenshot from my VSC Debugger:
go to post Pietro Di Leo · Apr 12 Hello, please check my article about this topic here: Accessing the IRIS Terminal: A Comprehensive Guide for Visual Studio Code (intersystems.com)Hope you appreciate it
go to post Pietro Di Leo · Apr 4 Hello, I encountered a similar issue but managed to resolve it. If you were connected directly to the server-side folders, try the following steps: 1. Click: View -> Command Palette -> Open Workspace Settings (JSON) 2. In the "folders" property of the JSON you should see something like: "folders": [ { "name": "<server_folder_name>:<namespace>", "uri": "isfs://<server_name>:<namespace>/" } ] 3. Try replacing the old one with the new one. If you were working on a local folder that was connected to a server, you should have a .vscode folder in your VSC workspace. 1. Try editing the settings.json file inside the folder. You should see something similar to: "objectscript.conn": { "server": "<server name>", "ns": "<namespace name>", "active": true } 2. Edit the connection with the name of the server you want to reach
go to post Pietro Di Leo · Mar 14 Thanks @Enrico Parisi, this is interesting. I'm going to check it out
go to post Pietro Di Leo · Mar 13 Hi @Muhammad Waseem, in the end I found a solution modifying the settings.json file, which contained all the info about my connection
go to post Pietro Di Leo · Mar 13 Hi Muhammad, great article! Do you know by chance how to switch from an instance to another through the ObjectScript extension? I have a local folder where I'm setting up a Docker instance, but the folder is linked to my IRIS local instance and it is not possible to unlink them even by doing Toggle connection or Refresh connection. Of course, I would like to connect to my containerized instance instead. Thanks :)
go to post Pietro Di Leo · Jan 17 I would like to export the project as an XML file, as is it possible in Studio
go to post Pietro Di Leo · Dec 29, 2023 Hi @Brett Saviano, thanks for the information! I just mentioned it in the proper section of my article.
go to post Pietro Di Leo · Nov 17, 2023 Thank you Brett, if it's feasible for you, link this article to the one you're writing in order to connect articles on similar subjects. I'll do the same
go to post Pietro Di Leo · Nov 9, 2023 Hi, you can try something like this: Set sc = $$$OK // Send a GET request Set messageStatus = httpRequest.Get() // Analyze response code If '($$$ISERR(messageStatus)) { If httpRequest.HttpResponse.StatusCode = 200 { // If a positive response was received // ... // ... } ElseIf httpRequest.HttpResponse.StatusCode = 404 { // Manage an HTTP status error // ... // ... // If you want a custom error status Set ErrorText = "This is a string that contains your custom error text" Set sc = $$$ERROR(ErrorCode, ErrorText) } Else { // You can manage other HTTP codes here } } Else { If '($ISOBJECT(httpRequest.HttpResponse.StatusCode)){ // Manage an error raised if the endpoint couldn't be reached or if you didn't get a response in time // ... // ... Set ErrorText = "This is a string that contains your custom error text" Set sc = $$$ERROR(ErrorCode, ErrorText) } } Return sc You can manage any status code in the way you prefer (not just code 200 or 404)
go to post Pietro Di Leo · Nov 6, 2023 I know that answering a question and providing your own response may seem unusual, but I won't delete this question as it could be helpful to someone in the future. The issue was related to the method "jsonFormatter.FormatToStream", which returned "ByRef" a pStream object that, for some reason, Postman and the other client software didn't handle well. A solution is to remove the jsonFormatter and to pass directly the OriginalStream to the function: Set pResponse = ##class(EnsLib.HTTP.GenericMessage).%New(OriginalStream,,tHttpResponse) If you prefer to keep the JSONFormatter, just declare the pStream as an object of %Stream.FileCharacter class before using the FormatToStream method: // Format the newJson with the correct indentation Set jsonFormatter = ##class(%JSON.Formatter).%New() // Declare a new stream object Set pStream = ##class(%Stream.FileCharacter).%New() Set sc = jsonFormatter.FormatToStream(jsonACK, .pStream) Now everything works fine.
go to post Pietro Di Leo · Oct 19, 2023 Thanks, Julius! That was part of the problem. I'm still facing some issue but now I'm able to reach a web service deployed with another program (in the next days I will retry with Render).
go to post Pietro Di Leo · Oct 15, 2023 The Gateway is very interesting, but could it work on 2021.1? Edit. I think so, as on Github it says IRIS supports the Gateway from version 2020.3. I will try it, thanks!
go to post Pietro Di Leo · Oct 13, 2023 Ok, probably that's the problem. I was looking for this information but I couldn't find it before. I'm not sure if I can upgrade the remote server. Is there an alternative?
go to post Pietro Di Leo · Oct 3, 2023 I don't know if this can help, but in objectscript the command to extract some elements from a list is the following: SELECT * FROM <tableName> WHERE FOR SOME %ELEMENT (<listName>) (%VALUE = '<value>')For example, if you have a persistent class like this: Class User.SQLtable Extends %Persistent { Property propertyList As list Of %String(MAXLEN = 100) [ Required ]; Index ListIdx On List(ELEMENTS); } You can extract information using: SELECT * FROM User.SQLtable WHERE FOR SOME %ELEMENT (propertyList) (%VALUE = '67') In this way you can retrieve the row that contains the specific data value of interest with dynamic or static SQL and subsequently extract the list as a property of the SQL result object
