Hi Thomas. If you plan to implement MVC, my advice would be to stick to
Java technology - it's by far the best for implementing MVC - I mean
literally the best! You may want to look at JSF or the Spring frameworkas
alternatives to Struts.

Hi all,

I'm a newbie to Zope, using version 2.7.3 (okay it is not the newest one)
and I want to know if there is something
like a MVC approach available for Zope, i.e. Model-View-Controller
approach, as it is for instance in Java with  the Struts framework from

To be more specific:

- The Model consists of several python classes implementing business logic
(the pendant to Enterprise Java Beans or simple Java Beans)

- The Views producing  the visual appearance of the business objects
 (in java or more specific in Struts these are the custom tag libraries)

- The Controller, as a kind of glue between the two above, is
controlling the work/process-flow
 (in java with servlets and in struts with actions classes (as a minimum) )

To transfer this appraoch to Zope, I'm not sure:

DTML-Document and/or DTML-Methods?


I'm absolutely not sure, Pluggable brains? (the Zope book has a example
but only as a handling of resultsets)

So if has anybody a hint if there are some resources
in the web, please post it.

P.S: I don't know Zope 3 (Is that apossible answer of my questions?)

Thasnks in advance

Hi Asad ,

I was afraid of that ;-(. But let me spin around yet:

- Views:
   --- Editing/Creating business objects:
ZPT's/DTML's with appropriate properties managing view concerns, genaralized for a category of possible (already standardised) business/zope objects (gaining from aquisition rules)
   --- Displaying Results: Pluggable Brains as subclass of above ones

- Model : Perhaps Zope Products ???, handling business logic , I'm not sure if that would work, perhaps a so
   called workaround with.interfacing and so on.

- Controllers:
  really PhytonSricpts, I think so, or alternatively dtml-methods

So, why I'm asking:

I want to implement a standardized web application (at this time it's only a stupid choose and buy like any other so called e-commerce/shopping cart system , but my intention is to make it almost configurable in all three aspects (i know ... but William S. wrote
#And enterprises of great pith and moment
#With this regard their currents turn awry,
#And lose the name of action. - Soft you now!
#The fair Ophelia! Nymph, in thy orisons
#Be all my sins remember'd.
################  ;-))

Is that totally wrong?
or is that a so called acceptable (but not ideal) approach?

Thanks in Advance
Thomas  Adams
