Here's the directory listing for mine. Make sure that "Extensions" is there. Extensions access lib utilities wo_pcgi.py zpasswd.py LICENSE.txt doc pcgi var wo_pcgi.pyc zpasswd.pyc README.txt import start w_pcgi.py z2.py ZServer inst stop w_pcgi.pyc z2.pyc Using a text editor, create a new file inside "Extensions" called "D_date.py". Put the code of the external method into D_date.py. Save it. If you're on a unix system, make sure that you add the folder and add the file as the appropriate user. This is often "nobody" or "zope". >From your Zope management web pages, add an external method to the root of your zope instance. Let's call it "D_date". (You can call it anything you want, so long as it is a valid zope id.) Fill in "D_date" (without the quotes) as both the python module name, and the function name.

Have a look at "sqlgroup" in "Shared.DC.ZRDB.sqlgroup". It does that, so you can learn how to do something similar. Dieter

What's the best way to go from Zope to Oracle time and back..
by Chris Beaumont 19 Aug '00

19 Aug '00

Total newbie question here.. The subject line says it all.. What's the best way to go from Zope to Oracle time and back? I would like to store the "beef" of my data in Oracle tables, and "instantiate" Zope objects from those tables.. Obviously this will require going back and forth between Zope and Oracle datetimes.. What's the best way to do this? I thought I had seen something like this in a HowTo, but I cant seem to find it.. Thank you. Chris cbeaumon(a)msri.org

Probable Bug in "OFS.Image.index_html"
by Dieter Maurer 19 Aug '00

19 Aug '00

Today, I met again a strange problem: I wanted to implement an image relay for an international project: something like: if an image in the target language is available, take it, otherwise, the english image. My DTML looked like: <dtml-let src="have_image(name,language) and _.getitem(language) or EN" image="_.getattr(src,name)" ><dtml-var "image.index_html(REQUEST,RESPONSE)"> The result was very strange: When I forced Netscape to reload the image (SHIFT + reload), everything worked fine. However, when I did a simple reload, it sometimes worked and sometimes did not (showed a broken image). When I loaded the image with Pythons httplib, everything worked fine. I tracked this down to line 219 of "OFS/Image.py": Zope arrives their, when it receives an "IF-MODIFIED-SINCE" header and determines that the browser has an up to date image in its cache. Zope correctly set status 304 and then returns "RESPONSE". It seems that this is not a problem, when "index_html" is directly called from ZPublisher. However, in the context of the above "dtml-var", it confused Netscape completely (I can understand that!). I changed the "return RESPONSE" into "return ''" and everything works fine again. I will put this into the collector. Dieter

[Ann] Another Zope Book
by Dieter Maurer 19 Aug '00

19 Aug '00

Dear Zopistas, I plan to write another book about Zope: "Building Dynamic WebSites with Zope". The book idea: Realize a demanding dynamic WebSite with Zope. Describe everything that is necessary for this purpose. This will contain: Concepts: HTTP, HTML, Zope, Databases, JavaScript, ... Components: catalogs, sessions, topics, news, discussions, stores, mails, LoginManager, customizers, workflows, ... Programming: building your own components (ZClasses and Product API) There will be some overlap with the official Zope book. However, my book has a different focus: I will not be complete about Zope. I will just describe the 40 per cent of features that are used for 85 per cent of the applications. I will cover aspects of dynamic Web publishing not directly related to Zope such as e.g. the basics of HTTP requests and HTML form processing. I will mainly stay near the concrete example dynamic WebSite. What do you think about my plan? Do you feel, it is worth persuing or redantant in view of the official Zope book? Dieter

Creating Graphs
by Stuart Foster 19 Aug '00

19 Aug '00

We need the ability to create multiple graphs from data that we get from Postgres. Currently we use a py method to call gnu plot, but we are looking for an alternative to serve up graphs. Any suggestions? I took a look at the Python Image Library is this the best solution? TIA Stuart

Both succeeded eventually in getting Xron started, but we didn't succeed in diagnosing the problem, nor in determining precisely how to work around it. I myself haven't been able to reproduce the problem. The problem seems to occur only on Linux, but it does not always occur. Some users have successfully started Xron on Linux with no problem. The problem seems to have to do with contention for a lock on ZODB. Did you see any log or console message that would confirm this? One user went to the console and killed all the Zope processes that were running at the time, then restarted Zope from the command line. The second time, Zope started up correctly with Xron. Another user thought that he had mistakenly tried to start Zope while logged in as root. When he restarted as a different user, Zope started up with Xron correctly. I suspect that the user was not relevant to the Xron problem (it is normal in some installations to start as root), but that the restarting was the key. One user thought that the monitor process contributed to the lock contention. I don't know, but it might be worthwhile to try to restart Zope without the monitor (changing the start-up options to disable the monitor). The problem seems to relate to Xron's creating the Schedule catalog the first time the Xron product is loaded during Zope start-up. If you succeed in creating the Schedule one time, the problem will not recurr, as Xron will just use the existing Schedule. I hope that helps you get started. Let me know how it goes. I'll copy this email to the zope list in hopes that someone else can shed some light on the problem. -- Loren ----- Original Message ----- From: "Nicholas Lo" <nicklo(a)siliconcreation.com> To: <lstaffor(a)dynalogic.com> Sent: August 18, 2000 12:41 AM Subject: xcron test > Hi Loren, > > I have a problem with installing Xron 0.9 onto my machine.

The problem is: I have a Zope 2.1.6 with SiteAccess and Apache 1.3.12 with the mod_proxy and mod_expire set up to that all request get at por 80 by Apache are proxed back to port 8080 of Zope. SiteAccess garantees that this cycle works all the time and port 8080 is never accessed directly. This works fine. The problem is that the Apache proxy is not caching the pages as it should, so that requests made to Zope once are not made again until expired from the cache. This results that every single request made to Apache goes directly to Zope and than the lack of robustness of ZServer makes it very slow and unstable (as expected). The strange thing is that the directory used for the cache is been filled up with files but it looks like Apache is ignoring them and going directly to Zope. When I shut down Zope, it never goes to the cached files and when I make requests to Apache the Zope´s log grows up all the time for the same bunch of pages. Here´s the configuration in my httpd.conf CacheRoot "D:/Program Files/Apache Group/Apache/proxy" CacheSize 50000 CacheGcInterval 1 CacheMaxExpire 24 CacheLastModifiedFactor 0.1 CacheDefaultExpire 1 CacheForceCompletion 90 ProxyPass /zope/ http://10.10.10.176:8080/ ProxyPassReverse /zope/ http://10.10.10.176:8080/ ExpiresActive On ExpiresDefault A86400 ExpiresByType image/gif A604800 ExpiresByType image/jpg A604800 ExpiresByType text/html M43200 Anyone knows why this happens? What´s the workaround? I searched through all the web and find nothing about the mod_proxy configuration so it´s turning to be extremelly difficult to maintain the Zope site, even with the robust Apache as the front-end.

You could use Xron to schedule sending the email. You could schedule it for later or for "now". Either way the email would be sent asyncronously from the original request.

Zope is a powerful and very deep products. The majority of users are unlikely to go into a great deal of python, most are going to use the dtml and other basic functionality. If Zope is going to increase its market then this sort of book is essential to make Zope accessible. Can I help at all? But a book covering the internals will be useful. One of my gripes about the documentation is how spread out and hard to find it is there's Wiki's here, presentations there... I've often searched zope.org and come up blank, when people on the mailing list can point it to me in 2 mins. But searching zope.org is another matter entirely :) my 2 cents. ----- Original Message ----- From: "Max Møller Rasmussen" <maxm(a)normik.dk> To: <zope(a)zope.org> Sent: Friday, August 18, 2000 2:19 AM Subject: Re: [Zope] [Ann] Another Zope Book > Fra: Kapil Thangavelu [mailto:kthangavelu@earthlink.net] > > >I think most developers are forced to learn > >through trial and error because the docs don't do the components justice > >since they tend to focus on working understanding of zope's framework > >from dtml. and in the end they are forced to turn to the source which > >can be confusing without knowing the parts of the framework from a > >fundamental not a working perspective. > > >comments? > > 2 right you are.

A *major* change between 2.1.x and 2.2.x is in the security dept. 2.2.x runs all methods using the security level of the _owner_ of the method, regardless of whether this is a lower or higher level than the currently authenticated user. My guess is that your method has no owner (which is what pre-2.2.x objects default to when run under 2.2.x). This means it is running as anonymous which does not have rights to do what you want. Specify an owner for the method that has sufficient rights to do what you want and try it again.
