I am using South 0.8.4 (refer to source
https://bitbucket.org/andrewgodwin/south/src/c26229113db6bbdebf36e6b31d76b45a48e29340/south/db/generic.py?at=0.8.4#cl-124)
The file south/db/generic.py has this function has_ddl_transactions
which access django.db.connection.features.supports_transactions
However, upon accessing, it gives an error. The error could be reproduced
by the following:
{{{
./manage.py shell
>>> from django.db import connection
>>> connection.features.supports_transactions
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/home/xx/venv/local/lib/python2.7/site-
packages/django/utils/functional.py", line 49, in __get__
res = instance.__dict__[self.func.__name__] = self.func(instance)
File "/home/xx/venv/local/lib/python2.7/site-
packages/django/db/backends/__init__.py", line 664, in
supports_transactions
self.connection.leave_transaction_management()
File "/home/xx/venv/local/lib/python2.7/site-
packages/django/db/backends/__init__.py", line 315, in
leave_transaction_management
"Transaction managed block ended with pending COMMIT/ROLLBACK")
TransactionManagementError: Transaction managed block ended with pending
COMMIT/ROLLBACK
}}}
Using south 0.8.4 and django 1.6. Seems like a Django error? But in the
first place, is it safe to access features attribute?
