ModelViewController

Notes on Model/View

The ZopeMozilla project has emphasized a need to break Zope into a Model-View-Controller (MVC) architecure. This need was reinforced by Jon Udell's talk at the Zope Track, in which he asserted that Zope shouldn't return HTML when an XML-RPC client adds a folder.

This Wiki collects information about MVC and how it can apply to Zope.

A Google search on model/view turns up quite a wealth of fabulously written pieces.

First, two articles with lots of pretty graphics. Model View Controller. Model-View-Presenter Framework.

Next, a terse architectural description at The Model-View-Controller Architecture.

A practical treatment is given at the model-view-controller design pattern . The resource also has a list of references. This is a tutorial spread across about ten pages that demonstrates MVC in practice using Java.

I'll be typing down my thoughts on this: ZopeMVC --MartijnPieters

My concern with MVC is basically what are we going to do about cycles? All of my MVC code in CPython has a finalize method that only exists to break cycles.

Please allow us to use plain text formatting, the code looks very poor.

Shalabh : Look at ModelCode now. I grouped the code in (pre) (/pre) and it worked! (bug in wiki?)

JodyWinston

Thanks, I added the (pre) and (/pre) to the code.

Here's some code to get the discussion started ModelCode, ViewCode, ControllerCode, EventCode, ReasonCode, ModelDetetedCode, CallbackCode, and a SampleUse.

A container that holds both the View and the Controller is shown in ObserverCode.
