They are required to instantiate the class in the ZODB. You omit it only, when you want your class instances be used for other purposes, e.g. pluggable brains (--> Z SQL methods). Dieter

We see something similar once in a while (about once in 6 month): * Zope stops serving requests: processes are there, no memory problem, no time consumption * Zope 2.1.6 on Solaris 2.7 We do not know what causes the problem. As it happens very rarely, we do not care much. Dieter

REMOTE_ADDR
by Marcus Mendes 25 Jan '01

25 Jan '01

I don't understand very much about Apache; but i've this lines in my httpd.conf. See: <VirtualHost xxx.xxx.xxx.xxx> ServerAdmin XXX DocumentRoot XXX ServerName myserver.xxx.xxx ServerAlias myserver ErrorLog /usr/local/apache/logs/error_log CustomLog /usr/local/apache/logs/access_log common ScriptAlias /script/ /usr/local/apache/script/ RewriteEngine On RewriteLog "/usr/local/apache/logs/rewrite_log" RewriteLogLevel 0 RewriteRule ^/local/ - [L] RewriteRule ^/(.*) http://myserver:8080/marcus/$1 [P] </VirtualHost> I'm using Zope.cgi with SiteAccess In the SiteAcess, I have -> base: http://myserver:8080 and URL : /marcus How can I pass to my ZServer the REMOTE_ADDR's content? Thanks a lot! Marcus Mendes. -------------------------------------------------------------------------- Oleg Wrote: Which way do you connect Apache to Zope? Mod_pcgi? mod_fastcgi? mod_proxy? I am afraid if you use mod_proxy - you cannot obtain remote address. Or may be there is a way to pass it explicitly to Zope. Other modules (FCGI/PCGI) should pass all neccessary information (actually, the entire request environment) by default.

RE: [Zope] How to make broken images/links broken!
by Farrell, Troy 25 Jan '01

I will try, although I don't completely understand your problem. Instead of refering to your images with html, try using dtml. This requires that the images are Zope Image Objects. Try this: <dtml-if expr="images.myimage.jpg"> <dtml-var expr="images.myimage.jpg"> </dtml-if> That will place the image on the page if there is any object called "images" with a subobject "myimage.jpg". But wait. There is a complication. The .jpg will really play with python. If possible, rename the image to "myimage_jpg" or just "myimage". Content-Type should take care of the lack of extension. This method also works it's way up the entire zope tree. May DTML methods cower at the sound of your name.

Hi folks, I think this has to do with acquisition. Here's my problem. I've an image, say http://localhost:8080/colorado/images/myimage.jpg Now, with Zope, if in a DTML document called http://localhost:8080/colorado/test.html , I refer to it as <img src="images/myimage.jpg"> it works as expected. However, if I have another DTML document called http://localhost:8080/colorado/slideshows/test2.html which *also* refers to it as <img src="images/myimage.jpg"> the image appears there also. I don't want this to happen. I would like this image to be broken as you would expect in a normal, dumb webserver. However, I don't want to turn off acquisition completely in all the folders too (I don't know how to do that either). Is there any thing we can do to test2.html which will not show things like this? FYI: This is for a content management application using Zope. We use Zope to make our content, then make static pages into file system to be served by IIS. All that works very nice. But users often give wrong URL for their images in the content and in the Zope DTML method (like test2.html) which does the preview, these images appear all right and so they think it is going to be OK in the static version too. I'm using something like ZIE for editor, so at least in that if we can disable acquisition, that would be neat.

"Treeing" a dictionary
by Gary Perez 25 Jan '01

25 Jan '01

Hi, all. I've been playing with the XML Document product and the <dtml-tree> tags. Works quite nicely. Is there any way to duplicate this "treeing" in Zope for a dictionary (with embedded dictionaries) coming in from an external method? For example, the external method is returning to Zope something like this: {'Category 1': {'Section 1': {'Key 1': 'Value 1.1.1', 'Key 2': 'Value 1.1.2'}}, {'Section 2': {'Key 1': 'Value 1.2.1', 'Key 2': 'Value 1.2.2'}}} Or, a little easier on the eyes: {'Category 1': {'Section 1': {'Key 1': 'Value 1.1.1', 'Key 2': 'Value 1.1.2'} }, {'Section 2': {'Key 1': 'Value 1.2.1', 'Key 2': 'Value 1.2.2'} } } Is there some way in Zope to tree this dictionary up like so (expanded)?: [-] Category 1 [-] Section 1 Key 1 Key 2 [-] Section 2 Key 1 Key 2 Alternately, what type of objects is the <dtml-tree> tag looking for when constructing the tree? Would it be easier to "programatically" generate those types of objects from the dictionary using either DTML or an external python module? Any help or insight is greatly appreciated. -Gary
