Passing variables to .ini config file

[BDuelz]

My config file makes use of variables like so:

sqlalchemy.url = postgresql+psycopg2://%(db_user)s:%(db_pass)s@127.0.0.1/%(db_name)s

And I pass them along like so:

pserve production.ini db_user=user db_pass=pass db_name=name

How can I pass these variables along using pceleryd?

pyramid_celery.commands.CommandMixin is using pyramid.paster.bootstrap to load wsgi application from PasteDeploy config file. The current version does not pass through additional commandline arguments following config_uri to the bootstrap call.

That matters

• pyramid.paster.bootstrap

Excerpt from docs
options Is passed to get_app for use as variable assignments like {'http_port': 8080} and then use %(http_port)s in the config file.

I changed a single line - the call to pyramid.paster.bootstrap

pyramid_celery.commands.init.py

from __future__ import absolute_import

import sys

from pyramid.paster import bootstrap
from celery.app import default_app


class CommandMixin(object):
    preload_options = ()

    def setup_app_from_commandline(self, argv):
        if len(argv) < 2:
            print >> sys.stderr, 'No configuration file specified.'
            sys.exit(1)
        bootstrap(config_uri=argv[1], options=argv[2:])
        self.app = default_app
        return argv[:1] + argv[2:]

The previous solution doesn't work anymore because we are deprecating the p* commands. I'm thinking the new api will be:

celery -A pyramid_celery.celery_app --ini-var database=postgres, user=sontek

I wanted to support multiple --ini-var calls but there is a bug in celery currently that breaks this. PR here:

celery/celery#2435
