DTML Problem (from the newbie "hair ripper" category)
by Darin Lee 16 Jul '00

16 Jul '00

Greetings, I have created a custom Zclass called "Category." This object is based on the "objectManager" template. Essentially this object is a container with a few properties attached; "navigation_name" and "description." Essentially, the gist of this is to create a navigation menu with a <dtml-in> loop that displays all of the Category('s) in a given directory. However, I want the property "navigation_name" to show up as the hyperlink text. Does this make sense? So, if I simply call the <dtml-in "objectValues(['Category'])"> and then print the name with <dtml-var navigation_name>, everything works fine!! Here is the proverbial rub. If I want to *test* for the presence of "navigation_name" so I can print "title_or_id" if it's not defined, Zope simply skips the "navigation_name" property. It's like it always evaluates to false! Example for "left navigation" dtml method: <dtml-in "objectValues(['Category'])"> <dtml-if "hasProperty('navigation_name')"> <dtml-var navigation_name> <dtml-else> <dtml-var title_or_id> </dtml-if> </dtml-in> Okay, I think to myself "self, maybe acquisition is getting in the way," so I try: <dtml-in "objectValues(['Category'])"> <dtml-with sequence-item> <dtml-if "hasProperty('navigation_name')"> <dtml-var navigation_name> <dtml-else> <dtml-var title_or_id> </dtml-if> </dtml-with> </dtml-in> Doesn't work! Could this have something to do with the definition of my own Zclass? Do I have to read into the property sheet specifically? Is there a command for that? I took the example from the excellent "Breadcrumb Navigation Trail Howto" and that works fine, as long as I use a supplied Zope object (like "folder"). As soon as I use my own ZClasses, this breaks. (I'd like to get my "navigation_name" into the breadcrumbs as well. Thanks in advance, -Darin Lee

It seems they forgot to compile the PCGI wrapper... here is what you should do to make it work: ---------------------- cd pcgi sh ./configure make --------------------- Worked fine for me.

2.2 installation problem on Linux
by Ragnar Beer 16 Jul '00

Howdy! Zope 2.2 (linux2) installs and works fine using ZServer but for whatever reason there is no pcgi-wrapper built in the pcgi dir so that I cannot call Zope.cgi. I checked again and again but ./install doesn't give an error message. What am I doing wrong? --Ragnar

That would be great ! Perhaps you can also find a way to do this recursively ? Have a look at my recursive copier: http://zdp.zope.org/projects/zsnippet/snippets/DTMLTags/recursive_copier This does it the other way around, but it can be adopted to do what you need. It would be handy if you have many instances floating around. Maybe you can also do it easier with a ZCatalog search ?

2.2.0 and Membership ... NoGo

Dunno what changed, but in 2.2.0b4 I could use Membership w/the latest ZPatterns just fine. In 2.2.0 when I try to add one, I get: "keyword redefined" errors. -- Do not meddle in the affairs of sysadmins, for they are easy to annoy, and have the root password.
