5191	"Handle ""None"" when type is <type: 'str'>"	Ari Kivimäki <arinium@…>	Adrian Holovaty	"Apparently at least pysqlite 2.3.5 (with Python 2.5) returns ""None"" (<type: 'str'>) instead of None (<type: 'NoneType'>) when a field is NULL. This causes problems with Django when conditional statement compares solely to NoneType and passes string values. Fortunately this is easily fixed: if the conditional statement (if not s: return None) on [http://code.djangoproject.com/browser/django/trunk/django/db/backends/util.py#L73 db/backends/util.py] line 73 is added another condition to satisfy str type ""None"" (if not s or s == ""None"": return None)."		closed	Database layer (models, ORM)	dev		invalid	None NoneType str String		Unreviewed	0	0	0	0	0	0
