Retrieve all classifications item with python

Mathias Jonathan — Wed, 26 Jun 2024 11:42:34 GMT

Hello everyone.

I'm pretty new to python, but I've managed to make a few scripts.

I am working on a script with a graphical interface, and I would like to be able to propose to select a classification in a Tkinter treeview style interface (keep the hierarchical system).

I've managed to retrieve the first and second levels of classifications, but my system is pretty basic in terms of code: I don't know, for example, how to find out the depth of the list retrieved by archicad.

Basically: how can I retrieve a hierarchical list with only the classification names?

My attempt (for the first and second levels):

from archicad import ACConnection conn = ACConnection.connect() acc = conn.commands act = conn.types acu = conn.utilities chooseClassification = acc.GetAllClassificationSystems() classifications = acc.GetAllClassificationsInSystem( chooseClassification[0].classificationSystemId) nbEnfants =0 nbEnfants2 =0 for classification in classifications: print(" "+classification.classificationItem.id + " " + str(len(classification.classificationItem.children))+" children") nbEnfants +=len(classification.classificationItem.children) for subelements in classification.classificationItem.children: try: print(" " + subelements.classificationItem.id + " " + str(len(subelements.classificationItem.children))+" children") nbEnfants2 +=len(subelements.classificationItem.children) except TypeError: print(" " + subelements.classificationItem.id) print(nbEnfants) print(nbEnfants2)

Not sure I can be of any help --But to retrieve the Classifications tree you need to use recursion. i wrote a classification interface for grasshopper which uses the Json interface and not the built in Python interface. Attached is a Demo Script - You would have to translate to the native Python interface which does not need Json.

Note that the two native classifications in Archicad use different Ids and naming convention. i assume you are interested in the Graphisoft default.

import json import urllib.request as rb #request = rb.Request('http://localhost:19723') request = 'http://localhost:19723' response = rb.urlopen(request,json.dumps({"command":"API.GetAllClassificationSystems"}).encode('UTF-8')) results = json.loads(response.read()) result = results['result']['classificationSystems'][0]['classificationSystemId']['guid'] response.close() response = rb.urlopen(request,json.dumps({"command":"API.GetAllClassificationsInSystem", "parameters": {"classificationSystemId": {"guid": result }}}).encode('UTF-8')) results = json.loads(response.read()) response.close() seed =results['result']['classificationItems'] output = [] level = 0 def get_ids(seed,kids = 0 ): global level level += 1 for item in seed: output.append( ' '*(level-1) + item['classificationItem']['id']) if kids >0: kids -= 1 if 'children' in item['classificationItem'].keys(): depth = len(item['classificationItem']['children']) get_ids(item['classificationItem']['children'], kids = depth) else: if kids == 0: pass # Debug only level -= 1 get_ids(seed, kids = 0 ) for x in output: print(x)

It worked well, thanks a lot!

here is my code (it's not clean, but it seems to work!)

from archicad import ACConnection conn = ACConnection.connect() acc = conn.commands act = conn.types acu = conn.utilities chooseClassification = acc.GetAllClassificationSystems() classifications = acc.GetAllClassificationsInSystem( chooseClassification[0].classificationSystemId) seed = classifications output = [] level = 0 def get_ids(seed, kids=0): global level level += 1 for item in seed: output.append(' '*(level-1) + item.classificationItem.id + " (level " + str(level) + ")") if kids > 0: kids -= 1 try: get_ids(item.classificationItem.children, kids=len(item.classificationItem.children)) except TypeError: pass # Debug only level -= 1 get_ids(seed, kids=0) for x in output: print(x)
