Instatiate object instances :-)
by Mario Valente 25 Jan '01

25 Jan '01

Hi: Can someone give any info/tips on the best way to solve this ? We have a folder "/content" containing all the diferent type of content we have available on our site. Within this folder, for example, we have a subfolder "/content/polls" where we store all the polls (instances of a Poll product). Another example, we have a subfolder "/content/articles" where we instantiate Squishdot articles. Now, the problem is that we'd like to reference those objects in several and different parts of the site. For example, we'd like to be able to reference diferent polls and diferent articles on area/folder "/Money"; and diferent polls and diferent articles on "/Games"; but an article could be referenced in "/Lifestyle" and in "/Money" We havent found an elegant OO solution. Up until now the only thing that comes to mind is that we should instatiate copies for the same object within each area/folder. This is a problem (duplicate copies, lack of data integrity, etc) The obvious solution in a non-OO paradigm would be links/pointers. But it is, of course, non-OO. And you cant do that on Zope anyway (can you?). The subject of this message is also another hypothesis: each object in Zope has a reference (the "Object Instance at #hiusd9743" messages...). Is it possible to instantiate object instances :-) ? This would be, of course, pointers. Any other options ? Is this a problem in our OO design (probable) ? How would you (suggest we) do it ? Any help/suggestions are welcome. C U! -- Mario Valente

Meaning of error?
by Steven Grimes 25 Jan '01

25 Jan '01

I'm trying to write a report for a system and When I try to view my document by clicking on the view tab at the top of the management screen I receive the following error: ! Temporarily Unavailable The resource you requested is temporarily unavailable - please try again later. (107) bad stdout strlen (0) The document calls three different queries which return a large amount of data. As far as I know the execution time on the page does not exceed the server timout setting because sometimes the page works and sometime it doesn't. Any help on what this error message means would be greatly appreciated.

Problem instantiating ZClass
by Åsmund Hjulstad 25 Jan '01

There appears to be something wrong... My config: Zope from CVS (2001-01-23, 16:15GMT) Python 2.0 (yes, I know it is not supported) I did the following: In Control Panel, generate new product. In the new product, Added new class (filled in the blanks). In the root folder: Add, select the new class, entered ID, and then... Error Type: AttributeError Error Value: _setId I have reproduced it several times, with several different CVS-versions.

=?iso-8859-1?q?=C5smund=20Hjulstad?= writes: > .... > > Error Type: AttributeError > > Error Value: _setId It appears that you ZClass does not include the "standard Python persistent classes". 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

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.

Hi everybody, I installed LoginManager-0-8-8b1 on Zope-2.2.2 by following the install.-instructions in the HOWTO: 'LoginManager with SQL DB' by jok. Nevertheless when I try to watch my TestFolder I get some weird error messages, like : Error Type: NameError Error Value: username ... any hints would be appreciated. Thanks Mario
