Thank you Michael,
in fact, my command-line script does use pyramid.paster.get_appsettings,
and I can read the setting just fine. My problem is with the SQLAlchemy
event listener in my model:
- The reindex_after_update function instantiates an IndexEngine object
- The IndexEngine attempts to read the settings using get_current_request
(see snippet below)
If the "after_update" event is fired from the Pyramid app itself,
get_current_request works. If it's fired from my command line script, it
fails.
I've also considered trying pyramid.testing.DummyRequest, but, if I
remember correctly, it doesn't contain the necessary info.
model.py
========
from my_indexation import IndexEngine
from .meta import Base
from sqlalchemy.event import listen
solr = IndexEngine()
class MyContentClass(Base):
...
...
# after_update Listener
def reindex_after_update(mapper, connection, target):
solr.indexObject(target)
listen(MyContentClass, "after_update", reindex_after_update)
myIndexation.py
===============
class IndexEngine(object):
def __init__(self, settings=None, request=None):
if not settings:
if not request:
request = get_current_request()
settings = request.registry.settings
# Read Solr URL
