possible security enhancement to CookieCutter product
by Mark Hays 09 May '99

09 May '99

I always enjoy Saturdays ;&) Attached are some mods to CookieCutter.py -- my changes start at "MIC stuff". The overall idea is to make it "safe" to stick arbitrary pickled python objects into cookies. And get them back again intact (with verification), of course. Comments/flames welcome, Mark

Iterating over items returned from external methods
by Ben Derstine 08 May '99

08 May '99

I have an external method that returns a list call List. I am using a DTML document to display the results of the method. As it is now Zope simply displays ['Sales', 'Marketing','Research'] However, I would like to be able to display the list by iterating over the list instead of directly displaying the raw list. I know about the DTML 'in' tag to iterate over a sequence. I just can't find any documentation on how to use it for a list returned by an external method. Would anyone have a simple example of this?

Zope 1.11 timeouts with IE 5.0
by Alexander Staubo 08 May '99

08 May '99

I'm having some problems on Zope 1.11 (running ZopeHTTPServer) with IE 5.0 (this is NT, SP4). Pages in the management interface usually load fine, but IE will never load images on first attempt -- they time out. A simple refresh on the individual frame will usually bring up the images. Occasionally single pages time out, as well, or the server gives a "connection refused". I experienced the latter problem with Zope 1.10.2 to a certain extent; with 1.11 it seems to have worsened.

I'd like to mention that Jim has made some additions to the Add ZClass screen that auto-generates a DTML Method Form, DTML Method Constructor, and a factory if you fill in a form element. This will make ZClass creation/instanciation more transparent. These changes will make it into the final 1.11. -Michel

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.
