Re: [Zope] Newbie (again) using PIDDLE with Zope

Thanks very much for your reply, especially the concerns you've raised (I'll try to make sure if we end up making this work, I bear that in mind when testing)! >That would be a question for the piddle mailing list (is it still active?). I remember trying a list before, pretty sure it was at sourceforge, and getting no real response, so I was just hoping someone here could help. >>Error: Value 'pdfgen' module has no attribute 'Canvas' Canvas is a class >>defined in pdfgen. >... well, apparently it's not. >Either that's the wrong name, or it lives somewhere other than pdfgen. >Sorry, I haven't looked at piddle in a long time and don't have it > >handy... As far as I can see, it is - but then I've been known to be wrong once or twice (an hour). This is a snip from the pdfgen.py file that I copied into lib: class Canvas: """This is a low-level interface to the PDF file format. The plan is to expose the whole pdfgen API through this. Its drawing functions should have a one-to-one correspondence with PDF functionality. Unlike PIDDLE, it thinks in terms of RGB values, Postscript font names, paths, and a 'current graphics state'. Just started development at 5/9/99, not in use yet. """ def __init__(self,filename,pagesize=(595.27,841.89), bottomup = 1): </snip> I could obviously copy more if necessary, I don't know if it would help .. ? It works fine when called outside of Zope, its just when I try it in Zope that it doesn't work. Any inspiration, anyone ... ? _________________________________________________________________ On the move? Get Hotmail on your mobile phone http://www.msn.co.uk/mobile

Strange folder creation
by Schmidt, Allen J. 02 Apr '03

02 Apr '03

Noticed lately that folders have been showing up in odd locations with odd names like: XYIZNWSK or some variation. And always owned by me. And no contents. And sometimes in folders I have not been in in months. Has anyone seen anything like this? Allen

RE: [Zope] Help with tree tag and localfs
by sysman 01 Apr '03

01 Apr '03

I did as you suggested, but I am afraid I am still a newbie at the python scripting. What I did was setup two scripts: filter_tree_nodes pres_docs_get_url And replaced 'root' with my localfs folder name (zinesfolder). I setup pres_docs_get_url with 4 parameters, but I don't know which to setup for sure. Are these correct? item_id, item_ext_list, item_name, root_url I still get nothing for objects in the folder. Just a thought, could this have something to do with LocalFS and Zope 2.6.0? -----Original Message----- From: AM [mailto:list_subscriber@neurobs.com] Sent: Monday, March 31, 2003 9:09 AM To: Greg Fischer Cc: zope(a)zope.org Subject: Re: [Zope] Help with tree tag and localfs In my case: <dtml-let root="pres_docs_storage"> <dtml-tree name=root branches_expr="filter_tree_nodes()" nowrap single> <dtml-var "pres_docs_get_url( getId(),hasChildNodes(), _['tree-item-url'], _['tree-item-expanded'])"> </dtml-tree> </dtml-let> where pres_docs_storage is the LocalFS instance. filter_tree_nodes: obs = context.objectValues() for ob in obs: if ob.getId() == 'index.html': obs.remove(ob) #not a good idea..

As a newbie to Zope I am trying to develop a simple Zope site. Looking at zope.org, I was wondering how 1. The user registration script works? (http://www.zope.org/Register/register) 2. The "Printable Page" script works? (something/pp=1) 3. The "Feedback to Author" script works? (something/feedback_form&came_from...) Would you be able to send me the source (DTML?) code for these scripts or tell me where I can get more information on this? Thank you very much! Niclas Kuehne

Hi, I want to build an html table based on the results of an LDAP query style ldap://ldap.abcd.fr/ou=people,dc=esrf,dc=fr??sub?(description=*Id17*) within a dtml method. How do I go about this? Do I have to install a LDAPUserFolder? If someone has a link to a good howto I would be very grateful (haven't yet found anything for the newbie I am!)

I managed to get a 20M snapshot of a Data.fs that exhibits the bug. I thought that the Zope team would be interested... ;-) Anyway, since some operations done in the interface brings functionality back it is something at least partially Zope. The only major problem is that it is not predictable! You can sometimes do tens of open/save from HomeSite and nothing goes wrong! I've dumped some of the traffic towards the machines but I didn't had time to analyze it. It looks like IE's requests leave the XP workstation arrive at the Zope server but the Zope remains silent... :-|

Debugging and Environment Variables
by Derek Basch 01 Apr '03

01 Apr '03

I am stuck on a minor problem that someone here could probably help me with. I have posted this a few times now and gotten no answers so ANY help is greatly appreciated. I am trying to simulate an HTTP request to the Zope Server using the techniques described in the "Testing and Debugging" chapter of the Developers Guide: >>> ZPublisher.Zope('') Status: 200 OK X-Powered-By: Zope (www.zope.org) Python (www.python.org) Content-Length: 1238 Content-Type: text/html <HTML><HEAD><TITLE>Zope</TITLE> ... blah blah... </BODY></HTML> >>> However, I am unable to get the simulated HTTP requests to return anything when I mimic the tutorial: >>> >>> ZPublisher.Zope('http://localhost:8080/') Status: 404 Not Found ..... Resource not found Sorry, the requested resource does not exist.Check the URL and try again.Resource: http://127.0.0.1/Zope/h ttp%3A ..... >>> I noticed that (http://127.0.0.1/Zope/h ttp%3A) is being called instead of (http://127.0.0.1:8080/) It seems that I need to set the SERVER_URL environment variable to (http://localhost:8080/) I have tried doing so like this: >>> ZPublisher.Zope("http://localhost:8080/", -e SERVER_URL="http://localhost:8080") but I get a syntax error. Can ANYONE answer my (apparently) stupid questions? Do I need to set the SERVER_URL environment variable prior to debugging? Is there something wrong with my Zope installation? Am I retarded beyond belief? Thanks Everyone, Derek Basch __________________________________________________ Do you Yahoo!? Yahoo!
