Dear all,
I'm writing a program using CherryPy and SQLAlchemy that works fine if
I don't use the SA session. When I start to use sessions I have the
following error:
Traceback (most recent call last):
File "webnmr_sqlalchemy_psql.py", line 2392, in ?
cherrypy.root.HttpProtected = HttpProtected()
File "webnmr_sqlalchemy_psql.py", line 180, in __init__
self.instruments=self.mysession(Spectrometers).select(spectrometer.c.tipology=='S',
order_by=['name'])
TypeError: 'Session' object is not callable
These are some few lines from the program.
import cherrypy
from sqlalchemy import *
class HttpProtected:
def __init__(self):
engine=create_engine('postgres://[EMAIL PROTECTED]:5432/NMR2')
metadata = BoundMetaData(engine)
projects=Table('projects',metadata, autoload=True)
class Projects(object):
pass
projectmapper = mapper(Projects, projects)
self.mysession = create_session()
self.instruments=self.mysession(Spectrometers).select(spectrometer.c.tipology=='S',
order_by=['name'])
Is it possible that the session managed by cherrypy conflicts with the
session used by SA? There is a solution?
Thanks
