I have an existing Web application written in Python that I'm looking to re-implement in a modern Python framework. Now that Grok is approaching 1.0, I am taking another look at it for this purpose, and it's lookin' good.<br>
<br>My only question (at this point, anyway) is whether there is a way to reuse existing SQLAlchemy-based model classes without having to add any Grok directives and/or Zope-specific integration code to them. The model for my application is in a "core" package that *cannot* be modified to support Grok (or any other Web framework) directly. One idea I have is a function that takes a SA mapped class and returns a Grok model.<br>
<br>I've started looking at some of the libraries for integrating SA with Zope/Grok, but I admit that I haven't looked very deeply as yet. I've also been reading the Grok docs and this list but haven't found a definite answer yet. Is what I want to do already possible? Would it be straightforward to implement something like an `sa_model_wrapper`? Can I create a subclass of a SA model class that uses `grok.Model` as a mixin?</blockquote>

You may want to checkout megrok.rdb [1]
but I'm not sure if it's what you are looking for.<br><br>Take a look to the doctest of reflection [2], I didn't try it my self, but it seems that you are able to define Grok models that will be mapped to existing tables.<br>
