Struggling with Permissions
by Jean Jordaan 15 Aug '00

15 Aug '00

Hi all I've run into something baffling regarding authentication. For debugging purposes, my standard_html_header tells me: (I'm <dtml-var "AUTHENTICATED_USER.getUserName()"> and I have <dtml-var "AUTHENTICATED_USER.getRoles()"> role(s).) When I visit /docs, it tells me: (I'm Anonymous User and I have Anonymous role(s).) That's cool. Now I visit: /docs/manage_addProduct/ccDoc/ccDocClass_factory via a link from /docs, and I am prompted for username and password. I add an instance of my ZClass, and am redirected to /docs: <dtml-if "AUTHENTICATED_USER.has_role('ContentManager')"> <dtml-comment> njj: Called from the public interface </dtml-comment> <dtml-call "RESPONSE.redirect( DestinationURL+'/index_html')"> <dtml-else> <dtml-call "RESPONSE.redirect( DestinationURL+'/manage_workspace')"> </dtml-if> (this is from ccDocClass_add). When I arrive I *still* see: (I'm Anonymous User and I have Anonymous role(s).) Now I edit the URL manually and visit /docs/manage, which works *without* prompting me for authentication. I edit the URL back to /docs, and now I see: (I'm docEditor and I have ContentManager and Manager role(s).) Also, this doesn't *always* happen. Perhaps it's an IE problem? Does anyone know exactly how this works? -- Jean Jordaan -- technical writer -- Mosaic Sofware -- Zope 2.16 on W2K

Z2.py DNS_IP (name resolution)
by Hugo Ramos 15 Aug '00

15 Aug '00

Yellow ppl, I inserted my local machine IP address in DNS_IP section of Z2.py as I used to in version 2.1.6 (now running 2.2.1b1). This used to work for me and instead of numbers I would get resolved names in the Z2.log. Since I upgraded to 2.2.0 and now 2.2.1b1 I only get numbers. DNS_IP section of Z2.py is not working properly anymore... anyone?? regards ===== Hugo Ramos - hugo(a)zopers.org ZopersORG - http://www.zopers.org ===== Do not meddle in the affairs of programmers, for they are easy to annoy, and have all the source code!!!

File uploads causing memory to be used up
by Tony McDonald 15 Aug '00

15 Aug '00

Hi all, I have an external method that uploads RTF files(and only RTF files) into a unix directory. It works fine, except it doesn't seem to release the memory it uses up in uploading the file. The method is; def process_file(self, file, location, REQUEST): if file.read(1) == '': return "NO file. Something wrong?" file.seek(0) split = string.split(file.filename, '\\') filename = string.lower(split[-1]) # save the file into the correct directory oname = os.path.join(savedir + location, filename) f = open(oname, "wb") body = file.read() f.write(body) f.close() if type(body) is not type(''): body=body.data content_type, enc = guess_content_type(oname, body, None) if content_type == 'application/rtf': # it's ok, we can go ahead and process this file. # need to strip off the .rtf extension however guideid = string.replace(filename, '.rtf', '') filesize = os.stat(oname)[6] # copy the file from savedir to opsdir os.system("cp -f %s %s" % (oname, opsdir)) # now cd to the operations directory and do some stuff. os.chdir(opsdir) # actually do the grinding... os.system("DoAGuide %s" % guideid) # return the output of the log file logfilename = os.path.join(opsdir, "%s.log" % guideid) f = open(logfilename, "r") logoutput = f.read() f.close() # get the template we're going to use for output. template_str = self.done.read_raw() template = DocumentTemplate.HTML(template_str) theresult = template(self, filename=filename, contenttype=content_type, filesize=filesize, guideid=guideid, logoutput=logoutput) return theresult return "File saved %s, size (bytes) %s. content-type [%s]" % (filename, filesize, content_type) The files are roughly 2-3 megs in size, and each time they're uploaded the amount of memory (as reported by 'top') used by the process increases by about that amount. *Any* ideas or thoughts would be greatly appreciated. We've had our server brought down twice by a python process (ie zope) that was taking up 1.1 gigs of RAM.

Looking up other row records in an SQLMethod?
by Theodore Patrick 15 Aug '00

15 Aug '00

Is it possible to look up other SQL record values while iterating through a <DTML-IN>? Sample Data returned by SQL Method: ID, ORDER 23, 1 25, 3 34, 6 39, 19 12, 23 Using a <DTML IN> I need to get the following during a single pass through the SqlMethod: HEADER >> ID ORDER PREV NEXT PASS 1 >> 23 1 null 3 PASS 2 >> 25 3 1 6 PASS 2 >> 25 6 3 19 PASS 2 >> 25 19 6 23 PASS 2 >> 25 23 19 null Calculating the PREV and NEXT is the problem and this cannot be done via SQL. 1. What is the syntax for writing out SQL Fields Directly? Say in a <DTML-IN> <dtml-var ID> <dtml-var ORDER> <dtml-var "ORDER[0]"> <dtml-var "ORDER[2] Any Ideas?? Thanks in Advance. Theodore E.

Structured Text Rendering
by Chris Withers 15 Aug '00

15 Aug '00

Hi, I have a list of string.strip'ped strings which I'd like to render using structured text. I'm currently trying: stx = str(StructuredText.html_with_references(join(storedLines,' \n'), level=3)) but that isn't working :( The text in the form submission is: """ sdfsdf - sdfsdf - sdfsdf - sdfsdf """ print join(storedLines,'\n') prints: """ sdfsdf - sdfsdf - sdfsdf - sdfsdf """ while 'print stx' ,very wierdly shows: """ p>sdfsdf - sdfsdf - sdfsdf - sdfsdf """ (what happened to the < for the ? and finally, what actually ends up in the HTML source as the result of this (which is called by <dtml-var "render(_.string.split(REQUEST['body'],'\n'),REQUEST.get('encoding','HTML'))">) is: """ sdfsdf - sdfsdf - sdfsdf - sdfsdf """ The questions are: 1) why all the extra newlines in the HTML source? 2) why just the one paragraph beign picked up, instead of 4? 3) why are the '-'s being turned into list items? cheers, Chris

Cannot save Version
by Jentsch, Peter 15 Aug '00

15 Aug '00

Hello! I created and logged in to a version object on my Zope-Site to do some extensive remodelling. When I tried to commit the changes, Zope responded with the following error: Error Type: KeyError Error Value: %} [...] Traceback (innermost last): File /opt/Zope-2.0.1-2/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /opt/Zope-2.0.1-2/lib/python/ZPublisher/Publish.py, line 179, in publish File /opt/Zope-2.0.1-2/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: Fake) File /opt/Zope-2.0.1-2/lib/python/ZPublisher/Publish.py, line 169, in publish File /opt/Zope-2.0.1-2/lib/python/ZODB/Transaction.py, line 237, in commit File /opt/Zope-2.0.1-2/lib/python/ZODB/DB.py, line 557, in commit File /opt/Zope-2.0.1-2/lib/python/ZODB/FileStorage.py, line 368, in commitVersion (Object: /dmz-inter03/opt/Zope-2.0.1-2/var/Data.fs) KeyError: (see above) where %} was preceded by 6 nullbytes. I'm still able to access the version, so I could reconstruct the changes after discarding the version, but actually I'd rather find a way to *save* the changes. Thanks Peter

I would not be that hard. I think political support is essential for the free software movement. I see this in Europe where the European Commission prepares to make software and business rules patentable -- a nightmare for free software and free look&feel. Therefore, it is not bad for the free software movement to support the right politics. I, personnally, do not mind *one time* announcements of the above kind. Dieter

Adding new News items using Yihaw
by Meaghan Aldridge 15 Aug '00

15 Aug '00

I am a Zope Newbie, and have been creating a company Intranet using Zope, and have stumbled across a problem that has me absolutely stumped! I have created a basic Web Interface using the Yihaw Product, and in this, I have added News Items. To search this, I use ZCatalog, which works quite well. The aim of this is to have a message board that authorised users can add and delete messages from. So far, the only way that I have found to add messages, is to actually add a new "Yihaw News" product from the Zope Management Interface. What I want to happen is that I can have a link to a page that displays a form with one field with the message to be displayed, and perhaps another field with a brief title. (The other fields, being the date and the name of the person who posted the message, I will have automatically, using the datetime function, and the authorised_user function.) This then generates itself into a Yihaw News item. Does anyone know how I could achieve this, or perhaps a work around for this? Thanks, Meaghan

Re: [Zope] Implementing a login form instead of BASIC authentication

They do something similar to what you want. Either, you can use them directly, or learn how they work and realize your own solution. Dieter
