Link check, site map for Zope with Apache?
by Craig Allen 08 May '99

08 May '99

I have not had much success with the link checkers (that are free and run on Linux) against my Zope-under-Apache site. Any suggestions of products, configurations of Apache or Zope, etc, that have worked for others? Thanks - Craig

Z Classes
by Tom Deprez 08 May '99

08 May '99

Hi, Amos, great job! Your tutorial of ZClasses certainly gave me a quick look on the capabilities of Z Classes. Following points maybe to add to your tutorial : 1. Before the tutorial begins, you maybe can describe what a ZClass needs for getting it to work. (So all the methods it needs for liminary working). Explain why these methods, properties are needed and how they are related to each other and Zope. During the tutorial, there is lots of switching between forms. If people know what they have to make or what it all means, they understand it better. A drawing helps a lot!. Also perhaps situate where the Classes are placed in Zope? 2. Some small modifications? Start by going to the Control Panel and creating a new Product. Choose "Product" from the add form and call it 'CDProduct'. --> Start by going to *** the Product Management screen in *** the Control Panel and creating a new Product.... ~~~~~~~~~~ For the Class 'meta-type' specify 'CD'. 'meta-type' basically means Zope Product type. --> For the Class 'meta-type' specify 'CD' ***and click 'Change' ***. ...... ~~~~~~~~~~ Creating a View Now let's add a View to our class which will let use manage these properties. --> *** Go back to the 'CDClass screen' ***. Now let's add a View to our class which will let use manage these properties. ~~~~~~~~~~ The final step is to create a Factory to put this add form into the Product add list. Choose 'Zope Factory' from the Product add list and create a Factory with id 'CDFactory', add list name 'CD' and method 'addForm'. --> The final step is to create a Factory to put this add form into the Product add list. *** Go to CDProduct screen ***. Choose 'Zope Factory' from the Product add list and create a Factory with id 'CDFactory', add list name 'CD' and method 'addForm'. ~~~~~~~~~~ 3. Maybe create also examples of the enhanced properties with CDProduct as example. ************************* Other question ********************************** Now that we've ZClasses, is it possible to get this done? And how? Assume we want to make a CD database. We just made are CDProduct ZClass (= CDProduct object). Now we want the users to add CD's to Zope. They have 3 screens : 1. Adding CD's. 2. Removing CD's. 3. Show the CD's sorted on title or artist. How can we store these? Can these be directly be stored into Zope? How? Do we need a relational database? How to get this done? Or in Zope's database? Can somebody enhance Amos's tutorial which incorporates the q'ns above? Thanks!!!!! Regards, Tom.

Of course, External Methods require you to put stuff on the filesystem which Zope won't let you do by default (I'm sure someone's decided that policy isn't valid by now! :^) . --Rob

This is one way, but can be rather difficult if you have lots of External Methods, it's a bit messy to keep your code in one place away from your object. A better solution is to create a Python class (in a Product) and sprinkle a little ZClass magic pixie dust in the __init__.py file to make the Python class (PClass) subclassable by a ZClass. Thus when you create your ZClass, you can specify that one of it's base classes be the PClass that you made subclassable. Now all of the PClasse's python methods are methods of the ZClass. Yeah! The Catalog uses this method heavily. In fact, the only methods actually defined in the ZClass are the managment and searching interfaces. All the guts are written in Python. > > The interface is a little clunky in places ie. how do you > make a view be > the second in the list instead of the first?

Play with it a bit and you'll get it how you want it. The add menu is simply sorted alphabetically.

This is probably a result of the DateTime.py class either not having your timezone setup or it only being setup partially i.e. missing the full timezone name reported by some operating systems. If you run Python standalone and type the following : import time print time.tzname it will report your current timezone. If you cannot get Python to run standalone then use the following as an external method : import time def getTimeZone(): return time.tzname After creating a new external method, use the Try It tab to view the resulting timezone. If you then open the DateTime.py file (found in "[your zope install]\lib\python\DateTime\DateTime.py"), goto the _zmap on line 186 and search for the timezone reported above. If it is not present then add a line similar to the following (which I have added to my DateTime.py): 'AUS Eastern Standard Time':'aest' and the lowercase version 'aus eastern standard time':'aest' where the key is the timezone string reported previously and aest is the abbreviated timezone of your area (the following New Zealand times are defined NZT, NZDT, NZST - if none of these are correct then add one in a similar format to 'nzdt':'GMT+13' where the GMT+13 represents the difference from Greenwich Mean Time in hours). Save the file, shutdown Zope and restart it. This should fix the problem. Robert Leftwich

Z Classes Question
by Jeff K. Hoffman 07 May '99

07 May '99

Hello, everyone. I am fooling around with Z Classes, familiarizing myself with 1.11's new features. First off, let me congratulate the DC guys on some cool new stuff; 1.11 is looking sharp! In my playing around, I have run across a situation which has prompted a question in my mind. Let's say I have a Z Class which is a subclass of 'Object Manager', so it's a container for other objects. Let's call this class MyFolderClass. MyFolderClass has an 'index_html' method which displays a simple HTML page. Now, I create an instance of this class called 'my_folder'. I want to be able to create a DTML Method, 'index_html', inside 'my_folder', overriding the default 'index_html' from MyFolderClass. However, when I try to do so, I get a "Bad Request" error (I can followup with more explicit information, should it be required.) Am I trying to do a No-No, or am I running into something which is not finished, yet? Thanks, --jkh

RE: [Zope] External methods and images

one other thing: this will only let you see the "real" exception that's causing the failure. there's still probably some problem with the external method you're calling, but at least now you'll be able to locate it. -----Original Message----- From: Wolf Logan [mailto:wolf@searchbutton.com] Sent: Friday, May 07, 1999 1:48 PM i think what you're seeing is the by-now-infamous ExternalMethod exception-handling bug (tm). ExternalMethod is seeing an exception in some part of the external method. in processing that exception, it assumes the exception type is a string, which it almost never is. this usually causes a second exception in the exception-handling code, which kills the function (and produces the traceback you see).
