We also switched from using the Python that came with 1.9 to using our own download of Python 1.5.1 > >You need to make sure that you are using a version of cPickle >with binary floats enabled.

I did not install Python and am not sure what to do. My initial questions are: 1) I have 1.5.1 of Python. Do I need to get the 1.5.2 version? OR.. Do I need to get a new version of cPickle? 2) I think we have the source for Python. Where do we change the option for cPickle to be dynamically linked or where do we specify the option -DFORMAT_1_3. Thanks for your help, John Solberg

tree tag global navigation
by Michael Bernstein 25 Feb '99

25 Feb '99

Fellow Zopesters, Here is a short tutorial on using the tree tag for global navigation in your site. Step 1: Create an external method with the following code: def getFoldersOnly(self): """Return a list of only the Folders contained in an object, for use by the tree tag""" return self.objectValues(['Folder']) This is neccesary in order to avoid listing the product and acl_users folder objects. Thanks to Kent Polk for the code. Modify this code if you want to display something other than just folders, For example: Step 2: Create a DTML method named SideBar in your root folder with the following code:  <A HREF="/"></A>  Notice that we are generating absolute URL's. Thanks to Kent Polk and Martijn Pieters for this code. Step 3: Call SideBar with the following code from anywhere in your site using this code:  And voila! it should display a tree of your entire site structure! Thanks to Amos Latteier for this deceptively simple code snippet. I hope this helps others who may have been struggling with this. Michael Bernstein

RE: [Zope] Upgrade Difficulties from 1.9 to 1.10.
by Shaw, Howard 25 Feb '99

No, idea. All I can say is I just went from 1.9 to 1.10.2, and all I did was copy the Data.bbb* files from 1.9 to 1.10.2, and bring it up. It came up with no complaints, so it is probably due to something specific in the contents of your database, and not anything general. I suggest using 'manageExportHack' or whatever that was in 1.9, then taking the bbe file and using 1.10's Import facility. As I understand it, manageExportHack flattens the current state of the database, losing the old versions and the undo ability. This might be a bad thing in some cases, but it might make your database more palatable.

DTML Methods v. Documents
by Christopher G. Petrilli 25 Feb '99

25 Feb '99

Since I just got caught in this one ;-) Is there any way to insert the RESULTS of a DTML Method into a DTML document (so namespaces are munged correctly)... basically... I've got a DTMLMethod dtFoo and I wont the RESULTS of it to be inserted into the document, but  obviously doesn't work. I'm obviously missing something :-) Chris -- | Christopher Petrilli ``Television is bubble-gum for | petrilli(a)amber.org the mind.''-Frank Lloyd Wright

Splitting the Zope mailling
by Ken Manheimer 25 Feb '99

25 Feb '99

As several people have pointed out, the traffic on the Zope mailing list is too heavy for comfort. We propose dealing with this by splitting off a separate list, zope-dev(a)zope.org, for handling developer-specific issues, leaving the current Zope(a)zope.org list for user oriented issues. To clarify, here are some examples of the way i see the division of topics: zope(a)zope.org zope-dev(a)zope.org ------------- ----------------- installation and operation dtml coding questions and hints content management using the programmer APIs desired user-level features new and existing architecture design business decisions contributed widgets w.r.t. open source public relations in general These are off the top of my head - and i'm relatively new to the community, so i'm quite open to suggestions about what belongs where. Overall question is, does the split make sense in principle? Please speak up particularly if you have objections. Barring substantial objections, i hope to institute the new list by the end of the week. Ken Manheimer klm(a)digicool.com

I don't think 'RegistrationSubject' is an illegal property name. I suspect there is a minor bug in the PropertyManager; properties have changed considerably from 1.9 to 1.10.2. I have added this to the Collector. We will be looking into it.
