[Zope-dev] ZPatterns style question

[Steve Spicklemire]

Hi Lex,

This is a little bit of a tricky question.  Here is what I think is the 
*intent* of ZPatterns. The details of storage are to be left up to the
implementor/integrator. Given that they are the only ones who really know where
all the goodies are hidden (sql? zodb? etc.. ) your app shouldn't 
assume any particulars here. What your app *can* do is demand that the
objects that are used satisfy a particular interface (e.g., have
certain methods or attributes that behave in particular ways.). With
ZPatterns, what look like attributes can really be methods, due to
the flexible nature of SkinScript. I see in your tutorial that you're
trying to help the integrator by putting SkinScript in for them...
but I think that in ZPatterns, it's probably better to leave that
up to them... or at least to assume ZODB ( something everyone has)
rather than SQL. Does any of that make sense?

take care,
-steve
