A URL is a string of characters so you can type a URL into a string property: If I defined a string property, href_to_home_page, as follows: href_to_home_page: <a href="http://www.zope.org">Zope Home Page</a> I could use it anywhere in my DTML as:  --Rob

ZWeather?
by Tim Wilson 23 Aug '99

23 Aug '99

Hi everyone, I've been thinking that it would be cool to have current weather conditions displayed on our science dept. home page. Getting the current conditions involves requesting them from weather.noaa.gov according to a code that refers to your location. There is already a little Python program that does this via email: http://freshmeat.net/appindex/1999/06/29/930711471.html Unfortunately, I'm a Zope newbie and not sure how to approach this. Obviously (at least it seems to me), you don't want Zope sending out a fresh request every time your page is updated. Is it possible for Zope to cache the results of the lookup for some period of time? Does this seem like a reasonable thing to accomplish via Zope? -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

ZOPE 2.0.0b5 & python 1.5.2: RH5.2 and RH6.0 RPMs available.
by Andreas Kostyrka 23 Aug '99

I've made ZOPE 2.0.0b5 and python 1.5.2 rpms available at http://www.zope.at/mze/ This rpms come with their own python compiled for ZOPE in /opt/mtg. Additionally, they contain the ZOPE version number in the package name to allow having multiple ZOPE versions installed.

URLs as properties
by Raymund Ramos 23 Aug '99

23 Aug '99

Hi! I wish there was a help button that tells me what I can do instead of having to post this... Under the properties tab, I can add strings, text (what's that? a whole file?), selection, multiple selection (what's that also?), but there isn't an URL option. I was imagining something like this: I define a myhomepage property and can do this:  and creates this html: <a href="http://whatever.value.was">myhomepage</a> Do I do this somewhat differently? How do you add more property types in that list? Please reply to me directly as I only subscribe to the digest version. Is there a way just to have the digest subjects mailed to me instead of the whole digest? Can I do this in Mailman? Has anyone put Mailman inside Zope? Thanks. -ray

ZODB and huge database.
by Andreas Kostyrka 23 Aug '99

23 Aug '99

Hi! I've been wondering what was the biggest database anyone has used with ZOPE? (I'm currently developing a ``file distribution'' server, in fact quite trivial, but it will have much data stored in it.) Has anyone done something about the 2GB datafile limit as found on Linux? (Using multiple Data.fs?)

I only used a DTML method to do the manage_cloning. As this seems to be a namespace issue, you could try to change to a DTML method or perhaps a <dtml-with "PARENTS[0]"> would help. Rik Hoekstra

HOWTO: Changing from DTML Document to Method and back.
by Andreas Kostyrka 23 Aug '99

23 Aug '99

Hi! This is only intended as a tip, because it might not have occured to all ZOPE developers yet. Sometimes, one wants to change a DTML method into a document or the other way. ZOPE doesn't support this (it doesn't fit to well into it's object model), but you can do this quite nicely with some browser help ;) My way of doing this is: 1.) Open the orginal object manage_edit in a new window. In netscape, just click the middle button on the item in Folder management view. 2.) Leave the new window alone for the moment an minimize it. 3.) In your folder management view, delete your original. 4.) Add the new object, be it method or document. 5.) Unminize the window created in step 1 and click on "Change". Close the window. Voila, you've changed the type of your entity without much fuzz.

Hmm... if "multiRes" objects can only appear within "photoCD" objects, it would probably be good to recreate the multiRes ZClass within the photoCD ZClass. This is good for two reasons: 1) multiRes will only show up as an option within photoCDs, 2) calling multiRes_add is really straightforward. ><dtml-with "manage_addProduct['photoCD']"> ><dtml-call "multiRes_add(_.None, _, NoRedir=1)"> ></dtml-with> > >since I want something in the photoCD product directory and what I >want is a multiRes ZClass right?

It shouldn't be hitting DestinationURL, because of the NoRedir flag. Did you modify the multiRes_add method (as mentioned in the first part of the howto)? Kevin

What >is the meaning of the "[]" as opposed to the "()"? Array instead of >function? Essentially, yes. Python lets you implement your own functions that figure out how to deal with [] or () for a given class. For manage_addProduct, they essentially made it a dictionary of Products. I admit that I did have to *guess* that /manage_addProduct/YourProduct/ZClass_factory from the HTML source maps to manage_addProduct['YourProduct'].ZClass_factory, instead of manage_addProduct.YourProduct.ZClass_factory. Though, when I think about it now, it makes a bit of sense because YourProduct is not actually part of manage_addProduct. manage_addProduct simply "points" to the product. >In the HOWTO it might be nice to point out that _ is a special >variable that contains the namespace and people should look in the >DTML users's guide for more info.
