These get added to the namespace within Zope somewhere. If you grep through the source files, you'll probably find it. (I'm guessing it happens in ZPublisher... But I haven't looked through that code to see exactly what's happening.) >#2.

Hmm... this should work <dtml-with images> <dtml-var imagename> </dtml-with> Should result in the creation of an <img> tag pointing to that image. Did you upload your images as "Image" objects or as "File" objects? > Also, how would I access the contents of subfolders of subfolders ? > <dtml-with foldername/subfolder> or <dtml-with foldername.subfolder> ? You could do: <dtml-with foldername> <dtml-with subfolder> </dtml-with> </dtml-with> Or, I believe, <dtml-with "foldername.subfolder"> (Note the ""s. Those are important) >#4.

I'm not running it under Solaris, but I'm guessing that this is the case. If you're using Apache, then you would need to change your rewriterules, etc... but if you're just using ZServer, I don't think you would need to do anything but delete the directory. >#5. How do you add Javascript events to images ? For example, for > rollovers ? Zope doesn't have anything specifically for creating rollovers... you just put the Javascript within your HTML the same as you would elsewhere. You could possibly write some DTML methods to make it easier on you, though. Kevin

I had a problem with SuSE that took me a while to track down that might be the answer to your problem. After making certain changes in yast, it would launch suseconfig which would change my port assignment for Apache from 8080 back to the original 80. (I had wanted to run Apache on 8080 and medusa on 80.) WARNING! I'm only in my first six months with un!x so I might have absolutely no clue. use this info at your own risk.

Converting a string to an int
by Timothy Grant 29 Aug '99

29 Aug '99

Hi, I'm working with a form that allows users to enter quantities. Into a table. on the next form, if I use <dtml-var "_[Category + '_qty']"> I get the value from the previous form exactly as I had planned--sortof. I then proceeded to do some calculations based on this variable and was told that I couldn't because it was a string. No problem thought I, I'll convert it to an integer and I used the following code to do so. <dtml-call "REQUEST.set('qty', _.string.atoi(_[Category + '_qty']))"> However, when I access the form, I get a Zope error that says: Error type: ValueError Error value: invalid literal for atoi() So, while it displays correctly, it does not appear to be a string, or an int: what is it? I have wondered if there was some weird translation error working with the _[Category...] stuff, so I assigned the result of _[Category...] to another variable and tried operating on it with the same result. Any clues would be appreciated. -- Stand Fast, tjg. Red Hat Certified Engineer tjg(a)avalongroup.net Chief Technology Officer www.avalongroup.net Avalon Technology Group, Inc.

Not a dumb question at all... I do this kind of thing all the time with Zope, and it is not necessarily completely obvious. If you want to set the value of a property, all you need to do is call: <dtml-call "manage_changeProperties({'propname' : propvalue})"> An alternate form, if the properties are all in the REQUEST variable (via a form, or whatever) and the REQUEST variables have the same names as the properties: <dtml-call "manage_changeProperties(REQUEST)"> If you don't want to log in to make the change, use a "Proxy Role" on the DTML Method. You can set the proxy role to "Manager", and then that particular method can do anything a Manager can do. Kevin

XML to Zope Objects (Folders and Properties) -- IMPORT
by Theodore Patrick 28 Aug '99

Is there a set of functions for conversion (Import & Export) of XML documents into Zope2? Specifically I am looking to import a large data set in XML(RDF) to Zope objects (Folders and Properties). Thanks, Theodore E. Patrick http://www.ishophere.com - Where do you shop?

absolute newbie question
by lethal＠innocent.com 28 Aug '99

28 Aug '99

hello, i worked for quite a long time with an odb content management system of a friend. i got used to get and set properties in the odb by simple assigning values to, resp. reading out values from the properties. something like <% node = new Node ("msg"); node.msgText = query ("msg"); % after a while playing around with zope (the version 2 beta) i found it wonderfully easy to read out data with dtml-objects. but i got stuck and confused trying to fill some data into a property the equivalent way. well, yes, it's not a problem in the management screen, no question. this works fine. but i am thinking of a web page one can open in a browser window without logging in or using the management screen. there, for example, one should be able to post a message and this message will be put into the odb. something like  (dumb question?) best regards, piefke

Re: [Zope] Serving Zope on port 80

Hmm... Sounds like your "admin" user is set up as a superuser on one machine, but not on the other. To bind to port 80, you need root (or superuser) access...

Serving Zope on port 80
by Albert Kinderman 28 Aug '99

28 Aug '99

I have two machines. On one of them I can use apache on port 80 and ZServer on port 8080 or I can reverse the ports. On the other, I can only use ZServer on 8080, but not on port 80. When I start Zope, I get File "/usr/local/Zope2.0b4/ZServer/medusa/asyncore.py, line 205, in bind return self.socket.bind (addr) socket.error: (13, 'Permission denied') On both machines I am running both Zope and Apache as "admin." I believe the permissions are set the same on both machines, but obviously I am wrong. Can someone give me some pointers on where to look?

Announce: First step in PythonMethods
by Evan Simpson 28 Aug '99

28 Aug '99

It took longer than I thought, thanks partly to a nasty stomach flu, but I've taken the first step in creating a PythonMethod Product. http://www.zope.org:18200/Members/4am/PythonMethod has the nitty-gritty. I'm satisfied with the performance of SafeBlock; Rough testing (available at the site) indicates that loading from ZODB is comparable in speed to DTML, and execution is an order of magnitude faster. Next step is to wrap this up in a Product, and think about what exactly 'import' should do in PythonMethod code.
