sqlacfg 0.3

Allows you to store configuration in an SQLAlchemy database instead of configuration files. The API is close, but not exactly like configparser and it plugs right into any application that is already using a declarative SQLAlchemy model:

# create a new model to hold the configuration items
class ConfigSetting(Base, ConfigSettingMixin):
    __tablename__ = 'configuration'

# instantiate the model with your session
config = Config(ConfigSetting, session)

# now config sections will work like a regular dict
config['section_foo']['bar'] = 123

# values will be json-encoded before being stored (this can be changed)
# to persist changes, simply commit the session
session.commit()

A full, minimal example is a bit more verbose due to the required initial setup:

from sqlacfg import ConfigSettingMixin, Config
from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

Base = declarative_base()
Session = sessionmaker()

class ConfigSetting(Base, ConfigSettingMixin):
    __tablename__ = 'configuration'


# for this demonstration, we just create the db in memory
eng = create_engine('sqlite:///:memory:', echo=True)
Base.metadata.create_all(eng)

session = sessionmaker(bind=eng)()

config = Config(ConfigSetting, session)

config['base']['foo'] = 'bar'
config['base']['baz'] = 'baz'

print dict(config['base'].iteritems())
