[...] Two things. First, if you write this could it be made available as a "hotfix" product so even if it gets rolled into the core of a future release those of us who do not update at every release can easily apply this to whatever version we choose to use... Second, the idea looks good, and would look even better if you or someone else would be willing to write up a detailed how-to around it so newbies could grok the whys and wherefors and make productive use of it faster and easier... just my $0.02 -- charlie blanchard http://baldguru.com/ LosAngeles area Zope Users Group http://lazug.org

So to make a very simple Zope product you just need to write::

from basic import basic

class minimal(basic): meta_type = 'minimal'

And it would set up a fully functional product with id, and title as default vales. manageAdd, manageAction, manage_editForm, manage_editAction, and index_html would also be included by default.

If you want to add more properties you would just overwrite "_properties"

from basic import basic

class minimal(basic):

meta_type = 'minimal'

_properties=( {'id':'title', 'type':'string', 'mode':'w'}, {'id':'summary', 'type':'text', 'mode':'w'}, {'id':'content', 'type':'text', 'mode':'w'}, {'id':'author', 'type':'string', 'mode':'w'}, {'id':'url', 'type':'string', 'mode':'w'}, {'id':'email', 'type':'string', 'mode':'w'}, )

And the manageAdd, manageAction, manage_editForm, manage_editAction, and index_html would change dynamically to fit the new properties.

You could also add new methods, or overwrite the default ones like::

from basic import basic from global import DTMLFile

class minimal(basic):

meta_type = 'minimal'

_properties=( {'id':'title', 'type':'string', 'mode':'w'}, {'id':'summary', 'type':'text', 'mode':'w'}, {'id':'content', 'type':'text', 'mode':'w'}, {'id':'author', 'type':'string', 'mode':'w'}, {'id':'url', 'type':'string', 'mode':'w'}, {'id':'email', 'type':'string', 'mode':'w'}, )

index_html = DTMLFile('www/index_html', globals())

view = DTMLFile('www/view', globals())

edit = DTMLFile('www/edit', globals())

I believe that it would _greatly_ simplify the process of writing Python products. Taking the minimal needed code to get started from something like 40 lines to 3.

Does it sound like a waste of time to write this class?? I think it would be fairly easy, but would anybody use it? And is it possible to get something like this into the core? If so I am willing to write it.

Perhaps this could be created as an "interface" class that has a bunch of inline documentation, but no guts. They seem to be sprouting up all over elsewhere in Zope... Reminds me of my Object Pascal days 8^)... -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>
