Hi Grokkers,

the last weeks a played a bit with "grok storm orm".

I have written a stormcontainer [1], which is heavily based on
the zachlemy container. In think the stormcontainer is in a
relativ good state.

On the new grok website i have written an howto [2], which shows
you the basic usage of my approach. (Sorry for the bad english!)
After discussing this on irc there are some
suggestions for inproving things.


In the package zope.storm it´s necesarry to define a store in zcml.
I think we can SMASH this zcml-slug.

   <store name="contact" uri="sqlite:/tmp/contact.db"/>

2. Make the grok config in our grok.Model easier:

This is the example Model of the Howto [2]:

   class Contact(grok.Model, Storm):
       __storm_table__ = "Contacts"

       id = Int(primary=True)
       name = Unicode()
       city = Unicode()

Maybe we can do something like megrok.storm.StormTable('Contacts') 
instead of __storm_table__ = Contacts.

3. The container config:

This is the config of the Container in the Howto [2]:

   class contacts(StormContainer, grok.Application, grok.Container):
       """ this application inherits from StormContainer too """
       def __init__(self):
           super(contacts, self).__init__()

Maybe it´s possible to say megrok.storm.setClassName('xxx') and 

So i think i have to work on megrok.storm package which includes
these simplifications.

Please give me some feedback.

Thanks in advance
