Hi,A Python script I've been using with Gnucash recently stopped working, and is no longer able to read files that could be read previously with the same script. The script can open Gnucash XML files, but it doesn't find the accounts in them. The script uses the official Gnucash Python API. Both Gnucash and the Python bindings were installed using the Fedora package manager. Here's the script: ``` from sys import argv from gnucash import Session, SessionOpenMode def account_from_path(top_account, account_path, original_path=None): if original_path==None: original_path = account_path account, account_path = account_path[0], account_path[1:] account = top_account.lookup_by_name(account) if account == None: raise Exception( "path " + ':'.join(original_path) + " could not be found") if len(account_path) > 0 : return account_from_path(account, account_path, original_path) else: return account if __name__=='__main__': gnucash_file = argv[1] gnucash_session=Session(gnucash_file, SessionOpenMode.SESSION_READ_ONLY) root_account = gnucash_session.book.get_root_account() investments = account_from_path(root_account, ['Assets','Investments']) ``` I'm experiencing this with Gnucash 5.9 on Fedora 39, installed using the Fedora repositories. I'm not sure how to tell whether this is a Gnucash bug, or a packaging error on the Fedora side, or something else. Any suggestions for diagnosing or troubleshooting this?
You might need to add `gnucash_session.load()` after your call to Session().
For background, see the thread "[GNC] unable to iterate accounts with API Python bindings" from October 2024 at <https://lists.gnucash.org/pipermail/gnucash-user/2024-October/113845.html>. The crucial insight, from John Ralls:
...there's been only one change to the bindings since then: I removed a load call from the Session constructor to fix bug 799308. That wasn't exactly the right thing to do, but it's a surmountable problem: Load the session in the script....
I hope that is helpful.
