There were some (proposed?) changes on the order/precedence of looking
in paths by import - see PYTHONPATH, virtual-python, .eggs,
xxx.path in site-packages/ and similar tweaks. u may eventualy
have multiple installs of some package; and then original "import"
may work very differently fro
Incidentally, the same problem is happening when using SPE as my
editor. Ordinarily it is able to open sources of imported modules so
the user can view the statement where an exception occurred, but in
the case of SQLAlchemy modules, it's going after the egg instead of
where the .py files actuall
My oh my... I found the problem. Even though the stack trace
indicated it was using cached objects, this must not have been the
case. Once I recycled Apache, everything worked fine.
Thanks for your feedback nevertheless,

That makes sense. I could do that, or I could just put copies of all
the needed files in the directory where winpdb's looking.
I guess my question is, why isn't the relevant stuff already in my
site-packages directory as a result of installing SQLAlchemy? I
followed the usual install procedure

dbsession = create_session()
results = dbsession.query(User).select_by(email='[EMAIL PROTECTED]')
for user in results:
print user.email
dbsession.close()
However, I get an error when the following code execu

Well, the two function are under "my control".

nothing *never* raises an exception. if you pass along bad arguments,
youll get an exception. theres no database operations or per-object
assertions within
Hi,
Here something you could try. Delete the egg and get a SVN checkout of
SQLAlchemy. Then copy the lib/sqlalchemy directory into your
site-packages directory (as "sqlalchemy"; omit the "lib/"). This
bypasses the egg mechanisms, which /may/ help.
