How to use Pyramid/models outside of WSGI/Paster

[somewhatofftheway]

I'm new to Pyramid and can't figure out how to do something which
seems like it should be quite a common requirement.

Basically, I want to write a script that will use the database models
but will not need to do HTTP requests. The idea is that I can run it
by cron or whatever.

The equivalent in Pylons is answered here:

Could anybody assist and tell me if there is a simple way to achieve
this? I have spent some time looking at Paster commands and the like
but without success.

Thanks,
Ben

Hi,

I guess that this thread already contain a reply:

http://groups.google.com/group/pylons-discuss/browse_thread/thread/fb1f4c49cf34eee2?hl=en#

But I'm agree that this point should be added in the pyramid
documentation with a recommended way to do that. It's a common need

Hi,

Thanks so much for your help; that enabled me to solve it. For convenience of anyone else, I did:

#Bring in pyramid application--------------------------------------

import pyramid
from paste.deploy import appconfig
config_file = '/path_to_config_file/configname.ini'

name = 'app_name'
config_name = 'config:%s' % config_file
here_dir = os.getcwd()

conf = appconfig(config_name, name, relative_to=here_dir)

from main_package import main
app = main(conf.global_conf, **conf.local_conf)

#--------------------------------------------------------------------------

I agree that a documented official way to achieve this would be good, I searched for quite a while and did not come across the answer.

Thanks again,
Ben

But that's really a python pastedeploy thing. you dont need the "import pyramid" to get the app initialized from configuration. 

Python Paste has docs, http://pythonpaste.org/deploy/#basic-usage

Maybe pyramids docs could elaborate on the capabilities of pastedeploy in this section.

http://docs.pylonsproject.org/projects/pyramid/1.0/narr/startup.html 

However I think things like that would probably not be in scope, it's probably good enough that PasteDeploy is mentioned and curious users can go research themselves. :)
