Hhmm - strange, on my SUSE-7.0 standard installation I can find the output of the print statements in /var/log/zope (most of the time, at least ;-). But I'll try zLOG.

Under Unix (and I think under Windows, too) you can redirect standard output to a file. The alternative is to use Zope's Log module (called zLOG). Its output goes to the log file. Dieter

You either access Zope for management purposes on 8080 or you learn how to convince IIS to forward authentication information. Maybe "doc/WEBSERVER.txt" says something about this issue. Dieter

PythonScript and ZClass generation problem
by Alexander Limi 16 Jan '01

16 Jan '01

Hi, We recently decided to use LoginManager for authentication on our site, and refactored our user registration methods to use PythonMethods instead of DTML. Now, during the registration of a user, we should also add a ZClass instance in the correct forlder. This object is a representation of some of the information the user provides when he registers with us. But we have stumbled across a problem. This is probably a very basic and simple problem, but I couldn't find any info on it on zope.org, and none of the people on IRC could help us either. So I'll try this posting instead. :) What we're trying to do is to add a ZClass instance/object programmatically from a PythonMethod. Our constructor is called Artist_add, and resides in our Product under the Control_Panel folder. The constructor uses variables that we have set in the REQUEST object. So the process is like this: User fills out form with variables that are put in REQUEST | Form calls "registerartist", which is a PythonMethod | "registerartist" creates the user | "registerartist" tries to call the constructor of our Artist ZClass to add an Artist object in our "artists" folder, but fails. To add the Artist object we tried to call the constructor in the following way from "registerartist": return self.artists.manage_addProduct['Artist'].Artist_add(_.None,_) but then the REQUEST object was not available, and the object creation fails since it can't find the variables it needs. The traceback for this was: File <string>, line 41, in registerartist (Object: ApplicationDefaultPermissions) File /usr/local/zope/lib/python/OFS/DTMLMethod.py, line 168, in __call__ (Object: Artist_add) File /usr/local/zope/lib/python/DocumentTemplate/DT_String.py, line 531, in __call__ (Object: Artist_add) IndexError: (see above) So we tried a different approach: return self.artists.manage_addProduct['Artist'].Artist_add(_.None,REQUEST) This solved the problem with REQUEST not being available, but now we can't access Artist.createInObjectManager. The error message we get is: "NameError Artist". So, I guess the question is: how can I add a ZClass instance programmatically from a PythonMethod? Additional version info: Zope 2.2.4 PythonMethod 0-1-7 LoginManager 0-8-8b1 ZPatterns 0-4-3b1 DataSkinAddons 0-0-2 Membership 0.7.8 Thanks in advance, Alexander.

Image Upload
by Fabio da Silva Santos 16 Jan '01

16 Jan '01

Hi there, I'm trying to insert an image in Zope by uploading it in an HTML 'file' field, using the following validation code: <dtml-if "banner_1 <> _.None"> <dtml-call "banners.manage_addImage(id='',file=banner_1)"> </dtml-if> When I submit an empty 'file' field, the dtml-call is invoked just the same, and I get an error message saying that the field is empty; when I check what's in REQUEST I see this: banner_1 <ZPublisher.HTTPRequest.FileUpload instance at 85fb998> Therefore, I reckon there must be something wrong with this validation routine. What should I do in order to run it properly? Thanks,

Problem on using nested <dtml-if>&<dtml-in>

Last, the only DTML-IF tag you need is that final one. Try this much, and see if all your probems go away. If not, let us know. Later, Jery S.

Take the libc_r.so.?? from OpenBSD 2.7 and toss it in some directory then add that directory to LD_LIBRARY_PATH and then start up Zope and see if that helps.. I think thats how I got Zope going for someone else a little while ago. I maintain Python, and came to the conclusion that Python is not at fault here, but libc_r. If this doesn't work let me know and I'll refigure out what I did. // Jason On Mon, Jan 15, 2001 at 02:15:37PM -0200, Diego Rodrigo Neufert wrote: > Are there any plans for patches that fixes this to come out? > > There are many ppl out there that are ancious to run Zope on OBSD 2.8! > > > -Diego > > On Monday 15 January 2001 02:04 pm, Brad wrote: > > Unfortunately, it's true.

patch to make GUF work with zope-2.2.5
by Andrews, Martin 16 Jan '01

16 Jan '01

Attached is a (very simple) patch to GenericUserFolder-1.2.4 that allowed me to use it with zope-2.2.5. I just derives GenericUserFolder from BasicUserFolder as as well as Folder (I also comment out a couple debugging messages that were failling). Since I am a newbie I wondered it anyone had comments on the security implications of this patch, or using GUF in general (are there other changes required for recent zopes to ensure proper security)? FYI - I had tried switching to LoginManager (0.8.8b1), but after struggling to configure it to replace my GUF usage I still managed to screw it up somehow and lock myself out of zope entirely - not even superuser could log in. GUF seems much better at always allowing superuser to authenticate. Martin --- Martin Andrews mandrews(a)netgenics.com

RE: [Zope] Adding content type to internet explorer
by Farrell, Troy 16 Jan '01

Actually, I'm not a newbie, but that is the nicest greeting a "newbie" has gotten on this list that I know of. Thanks. To see how IE looks at MIME types, look here: http://msdn.microsoft.com/workshop/networking/moniker/overview/appendix_a.as p >From the looks of it: IE first looks at the Content-Type: application/x-pdf (or whatever you are using) header from the server. If that is an unknown type and unambiguous, it returns the data as whatever the server calls it. If the type is known AND ambiguous (text/plain or application/octet-stream), IE parses the data and guesses. If it comes to no conclusion, then it looks at the extension. Try a <dtml-call expr="RESPONSE.setHeader('Content-Type', 'application/x-pdf')"> or whatever is appropriate for your application. AFAIK NS looks only at the Content-Type: header, but I consider myself ignorant in that area.

But I have done that before I posted the message. The thing is, changing Windows file type ("Classes") is not enough, because the IE would prompt you a question on whether you want to save the file or open it in place. I am asking the question because there are products out there that use the file-MIME-type trick to launch applications. That is, you click on a mundane HTML link and you launch a local application, without IE asking you any question. Obviously something inside the IE (or registry) has been tweaked. Anyway, a bit too technical. On the other issue of posting topics only related to Zope, I can tell you are a newbie.

ZPOP Popularity Property ?
by Jason Cunliffe 16 Jan '01

16 Jan '01

Hello I want to add a property to folders, documents and certain objects called 'popularity'. Can anyone offer some Zope advice how I might achieve the following: 1. Maintain an updated count of hits to those objects storing the number of hits, or preferrably an some offfset processed version of that number in 'popularity'. The processed value could take into account when and where the hits came from. 2. Search through folders and subfolders, checking objects 'popularity' value, and then return ordered lists to display of most/least popular. Preferably these lists would be Python dictionaries, and could be stored externally using BerkeleyStorageDB or similar so as not to extend the ZODB uneccesarily with small transaction data. This is inspired in part by a cool interface idea at: http://rhizome.org/starrynight/ <quote> Description When a new text is read for the first time on the Rhizome website, it appears on StarryNight as a dim star. Each time a text gets read again-by any Internet user around the world-the corresponding star gets a bit brighter. Over time, the page comes to resemble a starry night sky, with bright stars corresponding to the most popular texts in the database, and dim stars corresponding to less-popular ones. Dragging the mouse over one of the stars brings up a pop-up list of keywords that the corresponding text shares with other texts. Select a keyword in the pop-up list to draw a constellation linking all the stars that share that keyword. </quote> I have other plans how to 'render' the popularity results, including as boring but very useful XHMTL tables, using Zwiff [Zope Flash product based on Ming. see http://www.zope.org/Members/sspickle/Zwiff/] Thanks - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']
