Sprint to grok Zope
In the current state of Zope 3 the component architecture works out very well. One fundamental prolem remains though: to get started, you need to repeat yourself very often and configure a lot of things mostly with ZCML. Those XML sit ups are a pain. The sprinters want to show that those exercises are superflous.
The idea behind grok is to provide a simple Python API for writing a web application with Zope 3 and to reduce the amount of API calls by providing explicit defaults. Consider the following example for creating a model class and a view for it:
import grok
class Mammoth(grok.Model):
pass
class CavePainting(grok.View):
def render(self):
return 'A cave painting of a mammoth'
That's all. The CavePainting view is automatically registered for the Mammoth class. The example shows the basic idea:
- no ZCML at all
- convention over configuration
- configuration where required
It
is also planned for grok to make creating forms and schemas,
registration of adapters, creation of catalogs and much more much
easier.
