Run Pylons controller as separate app?

Question

I have a Pylons app where I would like to move some of the logic to a separate batch process. I\'ve been running it under the main app for testing, but it is going to be doing

Answer 1

If you want to load parts of a Pylons app, such as the models from outside Pylons, load the Pylons app in the script first:

from paste.deploy import appconfig
from pylons import config

from YOURPROJ.config.environment import load_environment

conf = appconfig('config:development.ini', relative_to='.')
load_environment(conf.global_conf, conf.local_conf)

That will load the Pylons app, which sets up most of the state so that you can proceed to use the SQLAlchemy models and Session to work with the database.

Note that if your code is using the pylons globals such as request/response/etc then that won't work since they require a request to be in progress to exist.
