Date: Thu, 27 Jul 2000 06:42:39 -0400 (EDT) From: Firestar [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [Zope] How to start developing in zope Hi, I have read through(and tried out) the tutorials and Guides at Zope.org, and now eager to port my company's website over to Zope. (The website was originally programmed in PHP) In my original design, I used OOP mainly. I defined each section(e.g. News, Events, Products) as a class by itself, inheriting from a "main" superclass. Each class would contain their own set of attributes(such as font-color, title) and methods(e.g. display news headline, or display events schedule). Common attributes method that are widely used are placed(shared) in the "main" class(e.g. talking to MySQL database). So, if there's any changes or updates, inheritance will propagate the changes to the rest of the subclasses. (As usual, management will require extra features such as personalised page, membership or web-based email to be added in future. Hopefully, this kind of structure would make adding new features a breeze.) I believe Zope is based on a similar way (and much more powerful). I was wondering how shld i start something like this in Zope - i read abt ZClasses(where you can define your own Folders), Products(for defining yr business logic) and DTML(for dynamic data display). Your opinions will be much appreciated. regards, firestar also, use properties which can be used as global variables... by the way, zclasses are a very good way using object-oriented tasks cheers, nico ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Your opinions will be much appreciated. regards, firestar My Take. zope adds enough complexity and options that they're is invariable More than one way to it. i generally do pure logic suff in base classes in python. and then setup an inherited zclass to do the display and sql stuff. i think you should also take rely on acquistion more for your sql issues. you're classes can acquire the sql stuff. try sticking an SQL folder in your root zope and call your methods dtml-in "SQL.myMethod()" /dtml-in or alternatively in the section for each class. acquistion is an integral part of zope and is pretty powerful for simplifying design and implementation.

I heard of this 'algebra of acquisition' written by someone...is it essential and where can i find it? TIA. In many ways, yes. Acquisition is very similar to inheritance, in that it deals with the sharing of namespaces. After that, it starts to become a little more complex. (o8 An important thing to remember if you're coming from an OO background (like C++, for instance) is that EVERYTHING is an object. Even the folders. I highly recommend you read the Acquisition Algebra document on the Zope website (easy to search for). The main exception to the normal rules of acquisition, it seems, is the DTML Method, which directly inherits the namespace of the referring object, instead of using AA. regards, firestar Have a better one, Curtis. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
