First, Sorry for disturbing you again and thanks AdeL and the others, With the python and postgres-dev installed I got build the PoPy-Module. But where is Zope searching for it? I still get the error message ******************************************************************** 2001-03-25T11:56:38 ERROR(200) Zope Couldn't import Products.ZPoPyDA Traceback (innermost last): File /home/zope/lib/python/OFS/Application.py, line 530, in import_products (Object: string) File /home/zope/lib/python/Products/ZPoPyDA/__init__.py, line 34, in ?

Also copying PoPymodule.so didn't work. It don't seems that the path for the modules in Zope 2.3.0 changed, or? I am working with PoPy-2.0.2 and ZPoPyDA-1.2, is maybe there a known bug? I don't see the mistake, thanks again for help. more and more confused Damir > Hey, > > You need postgresql-dev and python-dev to build PoPy. > Furthermore, if you are using redhat, you may need to change > /usr/lib/postgresql to /usr/lib/pgsql in your Makefile > > Good Luck > > AdeL >

Re: [Zope] Zope based Authentication.
by Mohan Baro 25 Mar '01

Thanks Tony and Dieter for replying. Zope is a great product. ZPatterns and LoginManager are great products too. I use ZPatterns and LoginManager. Thanks to http://www.zope.org/Members/BwanaZulia/zpatterns_install and other links Basic applicatiuon development require a lot of knowledge to setup. This will deter people from switching to zope from other platforms(for instance from PHP to zope). They also have access to free products and plugins from their user community. In order to develop PHP applications newbies just have to learn PHP programming. In Zope we have to learn Zope + Python + DTML + external methods to fully appriciate an application like ZPatterns and LoginManager. In oder to show that Zope means business when come to solid application development, certain thing must be built-in into Zope. One of them is form based login/logout system instead of HTTP authentication. I am new to zope but you have to understand that a lot of people are new to zope (and have a steep learning curve). Hope more people reply. Thank you. Mohan.

Hi All, Any ideas on the meaning of this error message: Error Type: TypeError Error Value: keyword parameter redefined It is raised at line 77, /lib/python/Products/PythonScripts/zbytecodehacks/inline.py The line of code that raises it is a call to a ZSQL method: logfile_line_id = context.sqlStreamInsertIntoRealRaw(eventId = eventId, client_ip_address = client_ip_address, timestamp = timestamp, get_filename = get_filename, protocol_and_version = protocol_and_version, http_status_code = http_status_code, bytes_sent = bytes_sent, platform = platform, version = version, client = client, type = type, distribution = distribution, language = language, cpu = cpu, client_guid = client_guid, stat1_packets_received = stat1_packets_received, stat1_out_of_order = stat1_out_of_order, stat1_missing = stat1_missing, stat1_early = stat1_early, stat1_late = stat1_late, stat1_audio_format = stat1_audio_format, stat2_bandwidth = stat2_bandwidth, stat2_available = stat2_available, stat2_highest = stat2_highest, stat2_lowest = stat2_lowest, stat2_average = stat2_average, stat2_requested = stat2_requested, stat2_received = stat2_received, stat2_late = stat2_late, stat2_rebuffering = stat2_rebuffering, stat2_transport = stat2_transport, stat2_startup = stat2_startup, stat2_format = stat2_format, stat3_string = stat3_string, file_size = file_size, file_time = file_time, sent_time = sent_time, resends = resends, failed_resends = failed_resends, sc_realaudio = sc_realaudio, sc_realvideo = sc_realvideo, sc_event = sc_event, sc_image_maps = sc_image_maps, start_time = start_time, server_address = server_address, average_bitrate = average_bitrate, packets_sent = packets_sent, presentation_id = presentation_id) TIA, Troy

connect to mssql with sybaseda on zope on NT?
by J�lio Dinis Silva 25 Mar '01

25 Mar '01

Hi, I have sybaseda installed on zope on NT. Now I want to connect to mssql :-) I create a sybase connection and enter user, password and server info but I get an Invalid Connection String. Has anyone successfully connect to mssql with sybaseda on NT? If yes, what could I be missing here? Maybe define a sybase data source somewhere on my sybase home poiting to my mssql server? My knowledge of sybase configuration files is limited so can anyone help me here? Maybe someone who made this on Linux knows where to define the data source.

Are Versions Reliable?
by Edmund Goppelt 25 Mar '01

25 Mar '01

I'm worried that Versions are not working properly on my Zope 2.3.0 web site. I'm trying to figure out whether I should continue to use versioning and/or whether I have a corrupt ZODB. What has been your experience with Versions? Is this a reliable feature of Zope? Have you ever been unable to roll back changes made in a Version or been unable to commit a Version's changes? Here's what happened: I recently committed a Version to the ZODB, but Zope showed many of the objects as still having uncommitted changes (the red diamond). Further, Zope showed many items as having changed that I know for a fact I did not edit (mainly Python scripts). Worst of all, the site became inaccessible to users, with Zope responding to page requests with a VersionLockError. Thankfully, Zope committed the changes after I saved the Version changes a second time, but the fact that Zope got confused about what had changed and what had not worries me a good deal. I don't understand why users were getting a VersionLockError--isn't the point of Versions that you can try out changes without adversely affecting your users? What is the best way to safeguard my data and web site, in your opinion? What would cause Versions to fail in this manner? Would packing the database help? -- Ed Goppelt

Re: [Zope] url question...
by Peter Bengtsson 25 Mar '01

You've got the string calling wrong. String.split() is a "builtin" python module for DTML. You call it by _.string.split() Besides... python syntax: '/'[-1] == '/'[0] == '/' == / Besides you haven't declare string as builtin with the _. <dtml-call "REQUEST.set('url_as_list',_.string.split(URL,'/'))"> Last objectid in URL: <dtml-var "url_as_list[-1]"> Or simpler: <dtml-var expr="_.string.split(URL,'/')[-1]"> ----- Original Message ----- From: "Junk" <junk(a)gargl.net> To: "Peter Bengtsson" <peter(a)grenna.net> Sent: Friday, March 23, 2001 6:57 PM Subject: RE: [Zope] url question... > > string.split(URL,'/')[-1] > > why can't i do <dtml-var expr="string.split(URL,'/'[-1])"> ??? > > junk >

web crawlers, robots & graphs / visualisation, zope-edu
by Lee 24 Mar '01

24 Mar '01

Hi there everyone, I have heaps of questions... Can any one tell me if Web sites developed using Zope can be indexed on search engines like Google / AltaVista when those wee spider fellas visit the server..? -- Also, assuming the following is possible, what would be the best way to implement such a system (and what are the alternatives)? Background: My system facilitates the creation of student and class information databases, and holds records of students grade, attendance records, etc. The student can access this the system to retrieve their records and relevant statistics. Right now, those statistics are the max, min, median and standard deviation value for every piece of graded coursework. Problem: Is there anyway I can visualise this data? I have a few ideas - if you have any thoughts or comments, please feel welcome... 1 - A Java applet - this is the most attractive option but put your hands up if you say that you shouldn't use Zope with Java. 2 - I don't know much about Python's Tk/Tkinter - could I use that somehow? 3- I have thought about creating a big much of .GIFs. I could maybe process all the data and store the layout of the graph in a 2D array and then use these 2 plot a graph by inserting an appropriate .GIF on the page. This would be fun but it would take me years!!! 4- I've already seen that I can export my data to MS Excel. Is it possible to do this again but have the data displayed *directly* in a graph upon viewing the data? I severely doubt this is possible... 5- Great idea for a new zope product : Data visualisation & graph maker!!! ;-) Cheers for any help. Lee PS: Zope-edu folks, I've spoken to my project supervisor to see if I can donate my project to your SIG. don't know if you can use it - but it's got some good ideas. if anyone wants to see a demo drop me a line...
