icons not in __init__.py
by Peter Bengtsson 05 Oct '01

05 Oct '01

When stating which icon to use for a python product you do that like this in __init__.py icon="event.gif" But what about subclasses which are object on their own? They don't use the initialize() method. I have tried: class SubClassObject(ObjectManager, etc): meta_type='Event' icon='event.gif' where event.gif is a valid gif next to the .py file I write this in. That didn't work! So, I have also tried: icon="misc_/MyProduct/event.gif" and icon="misc_/MyProduct/event" and icon="/misc_/MyProduct/event.gif" and icon="/misc_/MyProduct/event" Nothing has worked? Zope 2.4.0 What's the trick? Peter

Concurrent access with Apache and Zope
by Oliver Erlewein 04 Oct '01

04 Oct '01

Hi I'm having following phenonemon...if dtml-in with a sort on lots of data or I do a big ZCatalog-query then all transactions to Zope (2.4.0 on Sun Intel-PC) (after that transaction) wait for the first "big" transaction to finish before returning their results. This is naturally not so good if I want to have a site with about 50 concurrent users... I'd say the problem looks, as if I have only one thread returning results. Since I can't believe that Zope cannot handle parallel requests it must be my config. I already played arround with giving Zope more threads but it didn't change the behaviour. I use Apache 1.3.19 and Zope 2.4.0. Apache does SSL and the virtual hosting. Apache runs as Proxy Pass. I use the VirtualHostMonster on the Zope side to do the pathtranslation. I havn't checked things like FastCGI or PCGI. I'm desperate for an answer but I don't know where to look. So I'd be thankful for any help. Thanx Oliver -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net

proxyPass and Proxy Error
by Eric Vautour 04 Oct '01

04 Oct '01

Hello all, I have the following problem and I cannot seem to figure out how to resolve it. I have Zope set up and I am using a proxyPass in Apache to direct people to this site. Simple enough. Well the problem comes when Zope crashes, the Apache server returnes a ProxyError in a browser. My Question, Is there any way to have Apache direct users to an alternet page if Zope crashes. A static page on the apache server itsself for example? Thanks Eric

WINDOWS ODBC AND ZOPE 2.4 ISSUE

I download the latest version of Zope 2.4.1 for windows and all three the ZODBC adapter files. When I restart Zope I get the following error: "Python15.dll" bad path or filename. This file does not exist in the present installation. Do I need to reset the path to just python21.dll which does indeed exist. And which file would I need to tweak? I still looking.

RE: [Zope] Upgrading on Windows
by Meilicke, Scott 04 Oct '01

04 Oct '01

While I don't know the specifics of that upgrade path, you may want to try installing to a different directory than your 2.2.4, copy over any 3rd party products, possibly looking on zope.org for updates, and copy over your old data.fs to your new installation. You can run both instances of zope using different port numbers to do testing - see z2.py to set the port number.

Calling objects from Python script
by brian.r.brinegar.1 04 Oct '01

04 Oct '01

I would like to call an object that is passed to a python script. I run into a problem because __call__() takes different parameters depending on what type of object it is. For example DTML Documents take (client, REQUEST) and python scripts can take different parameters depending on how they are defined. Is there a standard way to call an object and assure that it gets the context and REQUEST variables? --Brian Brinegar ECN Web Technician MSEE 104 A 494-3106 http://www.geeksoft.net/

customize ZMI to hide objects?
by Eric Balasbas 04 Oct '01

04 Oct '01

How would I customize the ZMI to hide objects such as the Control Panel and DTML methods from certain user roles? We are building a website where users will change the content using the ZMI. We do not want the users seeing the Control Panel, DTML methods, or Python scripts since this would just confuse them. We just want the users to be able to see and edit the ZClasses that we have created for them. I have tried to look through the code, and I'm pretty sure I will have to modify some DTML code from the base Zope installation, but I'm not sure which files I will have to change. - Eric
