I am trying to develop a persistent scheduler (I'm using it today on a
live site) that can run jobs that access the DB. I'm using sqlalchemy
in my app.
When a job runs from the scheduler, the job runner code first grabs
the job record from the db.
The record has:
jobname, module name, function name, when to run (including
recurring), pickled parameter dictionary
The job runner loads the module, then invokes the function with its
parameters.
It works great unless the module it tries to load contains this:
import model
if it does, I get this:
Traceback (most recent call last):
File "C:\Projects\VOR\tg\vor\jobs.py", line 210, in runJob
module = __import__(modname)
File "C:\Projects\VOR\tg\vor\account.py", line 4, in ?
import model
File "C:\Projects\VOR\tg\vor\model.py", line 11, in ?
Column("content", Unicode)
File "build\bdist.win32\egg\sqlalchemy\schema.py", line 128, in
__call__
ArgumentError: Table 'None.keyed_file' is already defined for this
MetaData instance.
Does anyone have any idea what is wrong here?
I'm open to any ideas at this point... I need to run jobs that access
DB records through the model.
So this is a bit of a bummer.
TIA,
Jesse James
