I am working on a django app, and it's blowing up in this in
django/db/backends/mysql/base.py:

   def last_executed_query(self, cursor, sql, params):
       # With MySQLdb, cursor objects have an (undocumented) "_last_executed"
       # attribute where the exact query sent to the database is saved.
       # See MySQLdb/cursors.py in the source distribution.
       return cursor._last_executed


with 'Cursor' object has no attribute '_last_executed'

Sure enough, it does not:

$ python

>>> import MySQLdb
>>> conn = MySQLdb.connect(host, user, passwd, db)
>>> cursor = conn.cursor()
>>> print cursor._last_executed
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
AttributeError: 'Cursor' object has no attribute '_last_executed'
>>> print cursor.__dict__
{'_result': None, 'description': None, 'rownumber': None, 'messages':
[], '_executed': None, 'errorhandler': <bound method
Connection.defaulterrorhandler of <_mysql.connection open to
'localhost' at 889810>>, 'rowcount': -1, 'connection': <weakproxy at
0x62f630 to Connection at 0x889810>, 'description_flags': None,
'arraysize': 1, '_info': None, 'lastrowid': None, '_warnings': 0}


Anyone know anything about this undocumented (and nonexistent) attribute?


I've asked on the django list, but have not received any replies.
