Hi there!
In short:
Using Pylons 0.9.5 + SQLAlchemy + SaContext
When running app or tests all is OK.
But after change from pylons.database to sacontext for each 'nosetests
test_*.py' I get a "configuration error" in addition: "AttributeError:
No configuration has been registered for this process or thread" (full
error below)
In long:
I am a new user to Pylons. I do not fully _yet_ understand the whole
framework, but yet in the project we have managed to implement some
quite nice functionality.
I started a month ago with Pylons 0.9.5 and are not willing to upgrade yet.
Nevertheless, initially I was using default pylons.database for
SQLAlchemy, but a week ago I have tried successfully SAContext with
0.9.5 and it works. No major problems overall.
But when I run 'nosetests' for any test, then the test runs fine - all
the SQLAlchemy objects are managed properly, transaction management,
sqla sessions cool - but I always get additional 2 errors for each one
test class (2 errors are the same). Here it is:
<error>

</error>
Here is some details of configuration:
-Pylons-0.9.5-py2.4
-sqlalchemy-0.3.8-py2.4
-nose-0.9.2-py2.4
-Paste-1.4-py2.4
-PasteDeploy-1.3.1-py2.4
+ manually downloaded sacontext.py (0.3.3)
And part of my models/__init__.py:
#From 'SQLAlchemy for people in hurry'
import sqlalchemy as sqla
from sqlalchemy.orm import mapper
from portal.lib.sacontext import PylonsSAContext
sac = PylonsSAContext()
sac.add_engine_from_config(None) # <--- LINE 10
#All the businness classes are here..
from portal.models.domain import User
users_t = sqla.Table('users', sac.metadata, autoload=True)
#Etc...
mapper(User, user_t)
#Etc...
The are no modifications to Pylons base classes, configurations or whatever.
Just the necessary ones for using Mako.
config/* are almost original except routing.py,
lib/* the same..
Any ideas?
