error creating new gnucash file with python

[Ulrich Möhrke]

Hello,

I try to create a new gnucash file with python as done within
example new_book_with_opening_balances.py
(http://svn.gnucash.org/docs/HEAD/new__book__with__opening__balances_8py_source.html).

I wrote a tiny script:
-----------------------------------------
from gnucash import Session
from sys import argv
new_book_session = Session(argv[1], is_new=True)
-----------------------------------------

I get errors, if I call the script.
First.	- Call the script as
	python new_session.py xml://xml_test.gnucash
	I get the error:
		Traceback (most recent call last):
		  File "new_session.py", line 3, in <module>
		    new_book_session = Session(argv[1], is_new=True)
		  File "/usr/lib/python2.7/dist-packages/gnucash/gnucash_core.py", line 105, in __init__
		    self.load()
		  File "/usr/lib/python2.7/dist-packages/gnucash/gnucash_core.py", line 144, in new_function
		    self.raise_backend_errors(function.__name__)
		  File "/usr/lib/python2.7/dist-packages/gnucash/gnucash_core.py", line 122, in raise_backend_errors
		    errors )
		gnucash.gnucash_core.GnuCashBackendException: call to new_function resulted in the following errors, ERR_FILEIO_UNKNOWN_FILE_TYPE
Second.	- Call the script as
	python new_session.py sqlite3://sqlite_test.gnucash	
		Traceback (most recent call last):
		  File "new_session.py", line 3, in <module>
		    new_book_session = Session(argv[1], is_new=True)
		  File "/usr/lib/python2.7/dist-packages/gnucash/gnucash_core.py", line 104, in __init__
		    self.begin(book_uri, ignore_lock, is_new, force_new)
		  File "/usr/lib/python2.7/dist-packages/gnucash/gnucash_core.py", line 144, in new_function
		    self.raise_backend_errors(function.__name__)
		  File "/usr/lib/python2.7/dist-packages/gnucash/gnucash_core.py", line 122, in raise_backend_errors
		    errors )
		gnucash.gnucash_core.GnuCashBackendException: call to begin resulted in the following errors, ERR_BACKEND_NO_HANDLER

I get the same errors calling the example script new_book_with_opening_balances.py.

How to get rid of these errors?


Thanks, Ulrich
