Re: [sqlalchemy] create_engine returns a function, not a proper object

[Brian Van Klaveren]

Your code is buggy. You assigned the engine object then your parameters are 
actually a tuple which are immediately lost.

[sqlalchemy] create_engine returns a function, not a proper object

[Boris Epstein]

Hello all,

My call to create_engine which used to work at one point now return a 
function object.

The code:

if self.__dbConnectParams[DB_SERVER_TAG] is not None:
self.__dbEngine = sqlalchemy.create_engine
("mysql://%s:%s@%s:%s/%s" %
 (self.__dbConnectParams[DB_SERVER_TAG][USER_TAG],
  self.__dbConnectParams[DB_SERVER_TAG][PASSWORD_TAG],
  self.__dbConnectParams[DB_SERVER_TAG][HOST_ADDRESS_TAG],
  self.__dbConnectParams[DB_SERVER_TAG][PORT_TAG],
  self.__dbConnectParams[DB_SERVER_TAG][DB_TAG]))

print "DEBUG: pt 2: " + str(self.__dbEngine)

the resulting variable:

DEBUG: pt 2: 

Can anyone explain this? How does it happen? How do I fix that?

Thanks.

Boris.
