This sounds like a good idea, IMHO. The Zope Book doesn't go into much detail about technologies outside Zope. It sounds like your book would, and this would be a good thing. > -----Original Message----- > From: Dieter Maurer [mailto:dieter@handshake.de] > Sent: Tuesday, August 15, 2000 10:45 AM > To: zope(a)zope.org > Cc: woessner(a)springer.de; frs(a)lysia.de > Subject: [Zope] [Ann] Another Zope Book > > > Dear Zopistas, > > I plan to write another book about Zope: "Building Dynamic WebSites > with Zope". > > The book idea: > > Realize a demanding dynamic WebSite with Zope. > Describe everything that is necessary for this purpose. > > > This will contain: > Concepts: HTTP, HTML, Zope, Databases, JavaScript, ... > Components: catalogs, sessions, topics, news, discussions, > stores, mails, LoginManager, customizers, workflows, ... > Programming: building your own components (ZClasses and > Product API) > > > There will be some overlap with the official Zope book. > However, my book has a different focus: > > I will not be complete about Zope.

ZCatalog Question
by Jeff Sasmor 15 Aug '00

15 Aug '00

I have a product that has three CatalogAware Zclasses. They are indexed by the catalog correctly, but when I look at the catalog's status tab, the number of objects for each index are identical, even though the ZClasses themselves don't all have the same properties. Intuitively, this seems wrong. Or maybe my intuition is wrong. It "makes more sense" to have differing number of objects based on how many of each type of ZClass instance was indexed and what the properties of each one was. Anyone have any enlightenment (or is that Zen...) ? Jeff Sasmor jeff(a)sasmor.com

dtml-in and tuples

Hi, Why and how are python tuples (like, this) handled differently (and not in a logical way I can see...) than python lists [like, this]? cheers, Chris

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
