[Ann] DocFinder 1.0: ask Zope about its documentation
by Dieter Maurer 25 Aug '03

25 Aug '03

It is often difficult to find accurate documentation about the Zope infrastructure. Often, I have written: look into the Zope source, its source documentation is quite good. However, as Zope's implementation language Python provides good introspection facilities, there is a better way: extract the documentation directly from Zope. That's what 'DocFinder' does. It analyses any Zope object inside a running Zope, determines which classes have been used in the object's makeup and provides information about their class level attributes: name, allowed roles, arguments, documentation strings. It provides (read only) access to to source code of Python implemented classes and methods, as well. What's new in version 1.0: * Direct access to source code of Python implemented classes and methods * Implemented as a single persistent <code>DocFinder</code> instance (rather than a DTML object and External Method pair) * Alternative URL-calling to document objects which intercept traversal * Now uses PageTemplates rather than DTML for presentation More information and download: <http://www.dieter.handshake.de/pyprojects/zope/DocFinder.html> Dieter

Zope Start Up
by Bill Etheredge 25 Aug '03

25 Aug '03

We recently installed Zope 2.6.1 on a RH Linux 7.2 server. When we attempt to start Zope on this server, we get the following message: ------ 2003-08-25T16:07:40 INFO(0) zdaemon Started subprocess: pid 5635 ------ 2003-08-25T16:07:43 INFO(0) ZODB Opening database for mounting: '144205064_1059403198.767560' ------ 2003-08-25T16:07:43 INFO(0) ZODB Mounted database '144205064_1059403198.767560' at /temp_folder ------ 2003-08-25T16:07:43 INFO(0) ZServer HTTP server started at Mon Aug 25 16:07:43 2003 Hostname: xxxxxxxx Port: 8080 ------ 2003-08-25T16:07:43 INFO(0) ZServer FTP server started at Mon Aug 25 16:07:43 2003 Hostname: xxxxxxxx Port: 8021 ------ 2003-08-25T16:07:43 PANIC(300) z2 Startup exception Traceback (innermost last): File /local/home/Zope-2.6.1-linux2-x86/z2.py, line 748, in ?

How do I ask Zope for the name of an uploaded file?
by Cameron Laird 25 Aug '03

25 Aug '03

I'll abbreviate this: in a Python script that processes a file upload, how do I express the name of the uploaded file-- that is, the name of the file the user selected with his browser? I expected I'd find this in something like context.REQUEST.get_header('CONTENT-DISPOSITION') or context.REQUEST.get_header('filename') or somesuch, but I'm just getting None from those. Note that this information is available only through the HTTP dialogue; as near as I can tell, it is NOT available through the context.REQUEST dictionary. I anticipate a couple of possibilities. One is that some- one will know immediately what I'm trying to say, and will give me the one-line answer I'm after. The second is that my description puzzles everyone. In that case, I'll happily detail a model that should make all this clear. I prefer to avoid the work, though, if it's un- necessary.

standard_error_message weirdness
by Erik Myllymaki 25 Aug '03

25 Aug '03

trying to customize my standard_error_message - Zope 2.6.1 on win32 (win2k server) IE 6 client. if I use the simplest possible dtml-method: MyError I get a zope internal site error: ...traceback NotFound: MyError ... so it seems it wants a complete HTML doc. so I change the standard_error_message to: <HTML><HEAD><TITLE>Simplest HTML Error Page</TITLE></HEAD> <BODY> MyError. </BODY> </HTML> But the wierd thing is it gets displyed once or twice, and then the IE internal error page takes over (404, 500 mostly)... I'm pulling my hair out here - any advice appreciated.

How do I get the value of an object in python???
by Bill Hewitt 25 Aug '03

25 Aug '03

How do I get the value of an object in python and then pass it's attributes to a DTML method???? I run the following: > ## Look for Day Year (ie - Monday 2003) > for i in container.StyleBook.objectValues('Style Sheet') : > print container.StyleBook.loadStyle(title=i.title, > styletype=i.styletype, > bodycolor=i.bodycolor > ) > return printed and it runs fine against loadStyle - a DTML method I wrote to return a formatted CSS stylesheet..... But what I would like to do is use loadStyle in the context of i - in other words, use i's attributes as properties to loadStyle WITHOUT having to declare them all as arguments to loadStyle. What I cant figure out is, how do I get i's id and then pass it to container.StyleBook.loadStyle (python doesnt seem to like container.StyleBook.i.loadStyle) How does one do this? TIA WPH

Getting data from object inside ZClass
by Davis Marques 25 Aug '03

25 Aug '03

I'm developing a product using ZClasses, and I'm having some problems. When I make an instance of my ZClass, I want to copy a number of DTMLDocuments that are contained inside the ZClass to the inside of the new ZClass instance. Here's what I've got: # add a new instance of the ZClass, initialize properties instance = container.DPPortal.createInObjectManager(request['id'], request) instance.propertysheets.Basic.manage_editProperties(request) # the ZClass producthome = getattr(container,'DPPortal') # make a new DTMLDocument with data from default_css source = getattr(producthome,'default_css') instance.manage_addDTMLMethod(id='designportal.css',title='Default Design Portal stylesheet',file=source.data)

Python Script HowTo (WAS: How do I get the value of an object with python?)
by Bill Hewitt 25 Aug '03

25 Aug '03

Hi First it's great to be back on the list..... Had some problems for a few days. As Dieter pointed out I was not very clear in what I was trying to accomplish. (All my posts to this point have been related - as well as the post by davis(a)mccalldesign.com - which seems very similar...) Heres what I have: 2 ZClasses StyleBook (Inherits from Folder) | | | |---StyleSheet (Inherits from DTML Document) Unique title Property specifying when to use styletype Property specifying where to use At this point I can successfully create the StyleBook instance and add StyleSheet instances with the correct properties and through the ZMI, reset and/or view the results of those properties at will..... Now, I am trying to: * Via Python, collect all instances of StyleSheet that exist in StyleBook (via unique object ID) * Via Python, look at the title and styletype properties of each StyleSheet instance and compare them against my query arguments * If I find a match, return all the Property values(potentially 47+) of the particular StyleSheet instance (that are not empty strings) in a CSS Format. I cannot find any good *simple* howto examples of doing this with python. (With DTML I can do it, but it is very messy... Though I'm just learning Python, I would like to do it with python) Hope this makes sense......and Thanks for listening WPH

Shouldn't it automatically assume I'm an Anonymous User with the >Anonymous role? Yes, you *are* the anonymous user (see last sentence in error value). But something needs the "View" role (you created it, I guess, since it's not a default one). Do you have an index_html inside your folder, or is it acquired? Try to figure out what is "0" (item 0).

For some reason, there are no errors for many, but some people experience errors. I couldn't imagine Zope being browser or OS dependent, but that is what appears to be happening! beno
