Hello Zopeople, I found the menu suggestion below by Tino very good (exactly what I have been trying to do for the last week). I would like to modify it slightly though and can not get it to work. Can someone please help me out? How do I traverse the folder hierarchy of zope stopping at the first object with the property menue_root (I have it built into a folder like ZClass). I am trying to search *upwards* until I find the first object with a menu_root property (I want to make the sidebar menu start at a folder below root for departments of my faculty below the central pages)?

Punished for upgrading to 2.3.2: ZPatterns broke
by Itai Tavor 02 May '01

02 May '01

Hi, I shut down a Zope instance using Zope 2.3.1, and started it again with 2.3.2. When I tried to access objects on a rack, I got an AttributeError: _setRack. I went back to 2.3.1, but I still get the same error. Ok, I can take a hint. Somebody doesn't want me to use Zope 2.3.2. All right, I won't. But my project is still hosed. So now I got to restore a backup and lose a day's work. Is anyone else aware of upgrde problems with ZPatterns?

Accessing folders
by Chris Pedrotti 02 May '01

02 May '01

I'm new to all this, so please be patient. What I am doing at the moment is using <dtml-tree> to construct an html form of catagories for users to submit images to. I was setting the value of the radio buttons to tree-item-url and then hoping that I could just replace all '/' to '.' to access the folder that I wanted to image submitted to, and call manage_addImage. I was using <dtml-let> to assign a var to the folder url with the .'s and then calling <dtml-call "_[submitfolder].manage_addImage(id='', file=file, title='')"> Not working. Could anyone please point me in the right direction? Thanks. -Chris

Need some help with ZCVSMixin
by Itai Tavor 02 May '01

02 May '01

Hi, I finally decided it's time to get acquainted with ZCVSMixin, mainly because I was looking for a way to sync a project between a development and a production server. But I'm having problems getting started with it. I started a new project, checked it out to /home/itai/workspace/MyProject, created a CVS Folder instance in Zope in the MyProject folder, and then created and checked in some files and folders. No problems here, except for some trouble doing commits. Checkins work fine, but commit just hangs forever. I'm not sure I get commit at all - why is it such a long procedure? To do a commit I need to first click "Force Obj->File" and then select "commit" and click "Admin Function", whereas checkin is a one-click action. Anyway, I then wanted to see how I would use ZCVSMixin to update a production server. So I checked out a new copy of the project ( cd /home/itai/test; cvs co MyProject ), created a Test folder in Zope, added a CVS Folder to it and set its file system root to /home/itai/test/MyProject. Then I viewed the CVS object CVS Status page. I expected to see the objects that I checked out, but I saw nothing. Then, I created a new folder under MyProject, and tried to add a CVS Folder to it, but got errno 13, even though /home/itai/test/MyProject is owned by nobody, which is also the user running Zope. So: following the instruction in the ZCVSMixin README I can get a CVS-controlled folder working, although I can't commit anything in it, and I can do nothing with a new checkout copy of the project. What am I doing wrong? One other question, just in case I manage to solve these problems: I want to CVS the ZClasses in a Product along with the project folder, and it would be nice if they were both stored in the same repository branch. How should I set up the CVS Folder for the Product? I set it to use /home/itai/MyProject/Product. Is that a good idea?

Best way to set up a Product with multiple classes?
by Matthew Wilbert 02 May '01

02 May '01

I want to create a Product which allows creation of an container object which has a number of subobjects and sub-subobjects which can be separately instantiated within it. The subobjects should only be able to be created in the appropriate container object defined within the Product. I know how to do this (or something adequately similar, anyway) with ZClasses within a Product, but I don't understand how to do this with Python classes in a Python product. If the answer to that is too easy, I have a second question. Can I make a such a subobject be permitted in a finite number of containter types, so for instance a FloweringPlant could be added to a Garden or a Florist but not to any other container type?

How do you do a simple relocate?
by Tommy Johnson 01 May '01

01 May '01

Ok, first of all - I'm new to Zope (1 week). Now, what I'm trying to do is relocate from one page to another. Something very simple, such as if a user comes to a certain page, based on some variable, the user will be relocated to another page. I can do a server side include, but this really isn't what I wanted. Any help would be appreciated. Thanks in advance, Tommy _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

Zope Data Access Flaw?
by Brian Withun 01 May '01

01 May '01

I am using 2.1.4 (linux), and have stumbled across this little quirk... Create a ZSQL Method as follows: ================ SELECT <dtml-var "_.whrandom.randint(1000,9999)"> AS random_value ================ (Our ZSQL Method is connected to Sybase, but this works on MySQL as well) Then, simply test the ZSQL Method. Here's what I get: Random value ---------------- 2754 SQL used: select 7684 as random_value 2754 is clearly not the same as 7684. This is quite repeatable, with different random numbers each time. This works as expected if I replace the whrandom call with a constant, but I can't imagine how whrandom can be the culprit. Brián Withun
