cromlech.zodb 0.3.1

Cromlech Web Framework utility methods and components for application using the ZODB

Downloads ↓

cromlech.zodb provides utility methods and components for application built upon the cromlech stack and using the ZODB.

declare application with entry points

cromlech.zodb contains a utility to help initialize application based on entry_points provided by packages.

ZODB Context Manager

The zodb context manager gives you a handle on an application stored in a database.

LocalSiteManager

The package provide a PossibleSite class to be used as a mixin for your applications root objects:

>>> from cromlech.zodb.components import PossibleSite
>>> from zope.component.interfaces import IPossibleSite
>>> from zope.interface.verify import verifyObject

>>> site = PossibleSite()
>>> verifyObject(IPossibleSite, site)
True

This is a possible site, not yet a site:

>>> from zope.component.interfaces import ISite
>>> ISite.providedBy(site)
False

We can set up a local site manager:

>>> from cromlech.zodb.components import LocalSiteManager
>>> from cromlech.zodb.interfaces import ILocalSiteManager

>>> lsm = LocalSiteManager(site)
>>> verifyObject(ILocalSiteManager, lsm)
True

A Possible site with a local site manager becomes an ISite:

>>> from zope.component.interfaces import ISite
>>> ISite.providedBy(site)
True

Changelog

0.3.1 (2012-11-16)

  • fix on middleware, which was not iterating whole response

0.3 (2012-05-05)

  • General overhaul of the package, in order to provide better isolated components. For that matter, some of the context managers are now doing less, but they are more reusable.

    This change is NOT backward compatible. Update your applications.

  • Removed unfortunate print in the transaction wrapper.

0.2.1 (2012-01-27)

0.2 (2012-01-26)

  • Cleaned up application initializer.

0.2a1 (2012-01-10)
