megrok.nozodb 0.1

Using megrok.nozodb

To setup a grok environment which works without the zodb you have to replace the paster-application-factory which typically is located in the debug.ini and in the deploy.ini: To be concrete replace grokcore.startup#… with megrok.nozodb#nozodb

[app:grok] use = egg:megrok.nozodb#nozodb

The next you have to do is setting up global utility which acts as an ApplicationRoot which is a starting point for your application. megrok.nozodb has an ungrokked default one. You can subclass from it or provide your own stuff which acts as ApplicationRoot.:

>>> from megrok.nozodb import ApplicationRoot

>>> class MyApplicationRoot(ApplicationRoot):
...     pass

>>> myapp = MyApplicationRoot()
>>> from zope.site.interfaces import IRootFolder
>>> IRootFolder.providedBy(myapp)
True

>>> from grok.interfaces import IApplication
>>> IApplication.providedBy(myapp)
True

>>> from zope.location import ILocation
>>> ILocation.providedBy(myapp)
True

>>> from zope.interface.verify import verifyObject
>>> from zope.component.interfaces import ISite
>>> verifyObject(ISite, myapp)
True

API Documentation

We have to create a simple site definition file, which is also quite plain:

 >>> import os, tempfile
 >>> temp_dir = tempfile.mkdtemp()

 >>> sitezcml = os.path.join(temp_dir, 'site.zcml')
 >>> open(sitezcml, 'w').write('<configure />')

 >>> zope_conf = os.path.join(temp_dir, 'zope.conf')
 >>> open(zope_conf, 'wb').write('''
 ... site-definition %s
 ...
 ... <zodb>
 ... </zodb>
 ...
 ... <eventlog>
 ...   <logfile>
 ...     path STDOUT
 ...   </logfile>
 ... </eventlog>
 ... ''' %sitezcml)


 >>> from megrok.nozodb import nozodb_factory
 >>> app_factory = nozodb_factory({'zope_conf': zope_conf})

Clean up the temp_dir

  >>> import shutil
  >>> shutil.rmtree(temp_dir)
