What about adding a download tab to Document?
by Paulo Eduardo Neves 04 Feb '99

04 Feb '99

Hi, I think it would be nice to have a download tab in the document objects. Today we have to cut'n paste the form contents to an editor and save it with the desired name. Probably the usual development way is to edit a doc in the file system and to upload it. When you want to change, just edit it and upload again. Not very good when you have to edit a document from multiple places, or to edit documents that where automatically generated. Here is a patch to do it: http://samba-choro.com.br/neves/python/zope/Document.py.patch It should be applied to Document.py file in /web/Zope-1.9.0-src/lib/python/OFS dir. There's a kind of a hack in it to make the default file name in the browser download dialog to become "document_id.ztml". To do this a method is created with this name. If someone know a better way to do it, like a magic http header, please tell me. As you can see the default extension is .ztml (I liked it!). The mime type is text/ztml. If you want to change to dtml it is just a char in the code. regards, -- Paulo Eduardo Neves PUC-Rio de Janeiro Pager: Central: 292-4499 cod. 213 99 64 ou use a URL: http://www.learn.fplf.org.br/neves/mensagempager.html

Bizarre Authentication Problem.
by Christopher G. Petrilli 04 Feb '99

04 Feb '99

OK, I sent a copy of my database to support(a)zope.org, but... It seems that no matter what I do with security, that to get past the root folder of my site, you have to be authenticated... I know someone else complained about this one, and don't remember what the resolution is, and i cna't find it in the archives... Basically, I've tried overriding security for each folder, but nope, that doesn't work... Ideas? Chris -- | Christopher Petrilli | petrilli(a)amber.org

PDF needs ExternalFile Object with byte-range capability?
by Brad Clements 04 Feb '99

04 Feb '99

I need to start serving large .PDF files from my ZopeHTTPServer. I'm thinking that I'd rather not put the actual data into bobo. Does anyone have an ExternalFile object? Also, I'd like to support byte-range serving. I'm thinking that I could modify Image.py File class, in index_html check to see if REQUEST has a byte-range heading, if so use a range on self.data, as in return self.data[startoffset:endoffset] I'd also have to set RESPONSE headers. I'm concerned about getLen and len methods. Are they used to set the content-length response header? If I set a content-length header myself will that over-ride Zope's default process of setting the length?

Robert, I got similar error messages, because of the wrong permission setting of var directory. You can find some instructions in the install.txt.

03 Feb '99

I am having trouble attempting to access a Confera Topic instance given it's string name. I can:   . . .   or:  . . .  noting that testConfera is a <Topic Instance at xxx> However, I can't figure out how to retrieve the Topic Instance given the string name 'testConfera'. I can get several different types of instances (such as <ResultSet instance at xx>, but not a Topic Instance. How to?? Thanks Kent

Method Context Control
by Michael Bernstein 03 Feb '99

03 Feb '99

How can I control the context within which the various built in methods execute? For example, I am using a tree tag in a document method to display subfolders in my global navigation. However, when this method is acquired by a subfolder, its context changes and it only lists the subfolders of the current folder. I want to force this method to execute within its original context in order to display the entire site structure regardless of the page being viewed. If this is not currently possible, I would like to suggest that a 'context' attribute be added to , with the default being 'context=here' (the current behaviour) and an additional value of 'context=self' or perhaps 'context=origin' being made available. Another possible value for a 'context' attribute might be 'context=parent' to move the context up one level in the hierarchy. What do you all think? Michael. P.S. I do not yet have the programming ability to accomplish this... so I cannot submit a patch.

(Well, ok, some of the messages could be saved 'til college.) And with Zope, he'd have a killer tool for building that internet storefront to sell other people's products without spending a bundle.

Anybody have any experince combining two directories into one python package? For example say I have modules in two diffrent parts of the filesystem ../somepackage1 and ../somepackage2 Can I get python to treat them both as "somepackage"? --------------------------------------------------- - Scott Robertson Phone: 714.972.2299 - - CodeIt Computing Fax: 714.972.2399 - - http://codeit.com - ---------------------------------------------------

As you suggested, I figured it would be a good idea to get the paths functional for command line testing before tackling the Apache issue. I think I may need a step-by-step walk-through of where the paths for pcgi-wrapper should point. I thought I understood 'em, but no matter what I do, the wrong python continues to execute. The following is what I've tried (with '--more-path--' pointing to my home directory): PCGI_EXE=/--more-path--/local/bin/python PYTHONHOME=/--more-path--/local/lib/python1.5: PYTHONPATH=/--more-path--/local/lib:/--more-path--/local/lib/python1.5:/--m ore-path--/local/lib/python1.5/site-packages: PCGI_INSERT_PATH=/--more-path--/local/Zope-1.9.0-src/lib/python:/--more-pat h--/local/Zope-1.9.0-src/pcgi: Regardless of any of the above, what is executed is always '/usr/bin/python'. This is only happening through Apache, not from the command line. Thanks again, Chris PS I gotta say, of the various communities I've dealt with, you Zope people (hopefully soon I can say 'us', <grin>) are the most helpful I've ever experienced. Kudos!

hiding zope behind an apache proxy with mod rewrite
by stephen farrell 03 Feb '99

03 Feb '99

I want to hide zope on a internal site behind apache using mod rewrite and mod proxy of apache. The trick is that I want anything in /cgi-bin/ to go to apache, and anything else to go to Zope... but I want everything to appear to come from port 80 on the external server. I'm using ZopeHTTPServer. Here's what I've gotten apache to do (which seems to work OK): RewriteEngine On RewriteRule ^/cgi-bin(.*) /cgi-bin/$1 [L] RewriteRule ^/(.*) http://some.internal.host:2734/$1 [P] But the problem I'm facing is that zope writes all the URLs to http://some.internal.host:2734/whatever, instead of what they are supposed to appear as (http://www.mycompany.com/whatever) How do I tell zope that I want the urls to look like www.mycompany.com, and not to the internal site? (Preferably only to the outside world; I'm happy with the inside world using the internal URL). I've also tried setting SERVER_NAME and SERVER_PORT when zope is started, and then defining something like: MyURL to http://: which is all well and good, but then how do I get Zope to use this as the base? Setting <base href=""> didn't appear to do the right thing.... I want stuff like URL0, URL1 etc to work. Or, alternatively, is there a better way to accomplish what I want? What it comes down to is that I want apache around to run stuff in /cgi-bin on port 80 on the master server (critical), but I want zope to serve the documents on port 80 on the master server. I don't want /cgi-bin/zope.cgi?whatever either on the URL if it can be avoided. One thought I had was to use wget or similar to do a recursive get on the entire zope site, and then publish staticly. Does this sound like a good idea? (sorry for the rambling email--i'm very tired =) -- Steve Farrell
