Cannot Update Process Group's Variables

[mburger343]

• Nipyapi version: 0.19.0
• NiFi version: 1.13.2
• NiFi-Registry version: 1.13.2
• Python version: 13.10.5
• Operating System: Windows

Description

I am trying to update the variables for the NiFi Flow Process Group using nipyapi.canvas.update_process_group. I do not have a lot of experience with Python, and have not started using this api until last week, however I am able to update other properties for the NiFi Flow Process Group such as comments, so I think my code is correct.

What I Did

Here is some sample code demonstrating what I am seeing:

import nipyapi as nipyapi

pgeNifiFlow = nipyapi.canvas.get_process_group('NiFi Flow', 'name', True)

dictUpdateVar = { 'foo':'bar' }

dictUpdated = { 'variables': dictUpdateVar, 'comments': 'blah' }

pgeUpdated = nipyapi.canvas.update_process_group(pgeNifiFlow, dictUpdated, True)

assert pgeUpdated.component.comments == 'blah' # Does not throw an assert error assert bool(pgeUpdated.component.variables) is True # Throws an assert error

Urgency

It's not blocking me yet since I have other things to work on

I'm not sure your exact goal here, but if you want to update the Variables in the variable registry attached to a Process Group, you probably want to use nipyapi.canvas.update_variable_registry. If you are looking for code examples on how to use the various functions, then it is usually good to look in the tests for that function.

Thanks for the response. I missed the update_variable_registry, so I assumed that updating variables in the top level nifi group was the same as updating other properties
