Help in chaining calls to different method types
by roy＠anoobe.com 19 Feb '02

19 Feb '02

Folks, Could someone help me (relative Zope newbie) with understanding how I can chain method calls, with a mixed bag (i.e: py scripts, dtml methods and dtml documents"). I find that the following calling chains fail. DTML_meth -> DTML_meth -> Python_Script DTML_doc -> DTML_meth -> Python_Script For example: x_py: Python script takes 1 parameter (p1) URL works standalone (http://localhost:9673/Test/x_py?p1=23) meth_1: DTML method takes 1 parameter (p1) and passes it to x_py body is: <dtml-var expr="x_py(p1=p1)"> URL works standalone (http://localhost:9673/Test/meth_1?p1=44) meth_2: DTML method takes no parameters body is: <dtml-var expr="meth_1(p1=66)"> URL fails (http://localhost:9673/Test/meth_2) I get the following message: Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: global name 'x_py' is not defined doc_1: DTML document. takes no parameters body is: <dtml-var expr="meth_1(p1='ha')"> fails the same as meth_1. URL fails (http://localhost:9673/Test/doc_1) Thanks, Roy Mathew.

RE: [Zope] shared data / synchronisation

Can you be more specific about what you want to do? I wonder if I'm understanding correctly... Why not just use a class variable for all instances of a class implemented for this purpose instead of instance variables? You can do this with both ZClasses and Python products...

I'd like to have somethig like the static variables in C++ or Java. And if I am not mistaken, that is a serious Zope-weakness which causes the many many problems with connecting to databases. If anyone of you can tell me I'm wrong and why, I'd be happy. If not: any idea how to do it? If possible: a clean solution.

getting filename cross platform
by John Hunter 19 Feb '02

19 Feb '02

I have a file upload form which gets a filename from the local file system and then passes it to a Python Script which adds the file to the Zope filesystem and returns the filename. I want to return just the filename with the local path information stripped off. This works fine when the file is uploaded from Linux, but not when it is uploaded from Microsoft Windows. Here is the python script ## Script (Python) "add_to_filesystem_py" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=folder_name,file_name ##title= ## REQUEST = container.REQUEST RESPONSE = REQUEST.RESPONSE idFolder = getattr(context.Patients, REQUEST.get('pid')) folder = getattr(idFolder, folder_name) folder.manage_addFile(id='', file=file_name) return getattr(file_name, 'filename') If pid, the patient id, is '1234', folder_name is 'images' and file_name is '/some/path/to/somefile.dat' this will add '1234/images/somefile.dat' to the Zope filesystem and return 'somefile.dat'. But in windows if file_name is ' 'C:\some\path\to\somefile.dat', the same file will be added to the Zope filesystem but the entire filename with path will be returned. I think this is related to the id/title distinction. In the manager interface, the linux files are listed as somefile.dat (somefile.dat) and the microsoft files are listed as somefile.dat (C:\some\path\to\somefile.dat) So it appears that it is the title that is being returned when I want to the Id. Any suggestions on how I can modify my script to return the Id of the newly created File object? Thanks, John Hunter

Zope 2.5.0 + Python 2.1.2 + LDAP
by Thierry Florac 19 Feb '02

19 Feb '02

Hi !! I'm currently using : - Zope-2.5.0, - Python-2.1.2 - libldap2-2.0.23 - python-ldap-1.9.999.cvs.20011231 All these packages are installed on a Debian system just upgraded from 'Stable' to 'Testing'. I'm trying to use several LDAP user managers (LDAPUserFolder,...) or LDAP query tools but as soon as I try to execute any query, I receive an error message : "python: /usr/local/src/libopenldap/openldap2-2.0.23/libraries/libldap/references.c:26: ldap_first_reference: Assertion `( ( ld )->ld_options.ldo_valid == 0x2 )' failed." or "python: /usr/local/src/libopenldap/openldap2-2.0.23/libraries/libldap/error.c:220: ldap_parse_result: Assertion `( ( ld )->ld_options.ldo_valid == 0x2 )' failed." These errors make Zope restart every time, so these LDAP products are unusable... ; these errors didn't exist with old releases of Zope (2.3.3) and Python (1.5.2). I've tried to execute a few LDAP queries from within Python interpreter, and they seem to be OK so I think Python-ldap is correctly installed. Any idea ?? Thanks for any help, Thierry -- Linux every day, keeps Dr Watson away... http://gpc.sourceforge.net

Zope Syndication
by Ot Ratsaphong 19 Feb '02

Further to my query on getting the zope news.rss to display, I got it to display on my browser by removing the line with <dtml-var "channel['title']">. I think this line is supposed to show the channel title, but some reason zope is not accepting this syntax. I anyone knows how to get past this syntax problem, please let us know. Thanks, Ot Ratsaphong

Please help newbie access her control manager/panel
by J. Stuff 19 Feb '02

Dear Zope Group, I am trying to use Zope at home and am wondering if someone might be willing to help me get started. I have installed Zope 2.4.3 on my new windowsXP machine, but I can't access the control manager. I've tried the following URLs: http://localhost:8080/manage http://127.0.0.1:8080/manage and was told by my browser (IE 6.0) the "page cannot be displayed." Since those didn't work, I looked up my computer's hostname: I typed "hostname" in a command prompt and found it is "joplop-alpha." So then i tried: http://joplop-alpha:8080/manage Still, "page cannot be displayed." I don't know how to change the hostname or where it is even located as I am very unfamiliar with windowsXP. When I run start.bat (as the online zope book instructs) a dos prompt opens containing the following information: C:\Program Files\WebSite>"C:\Program Files\WebSite\bin\python.exe" "C:\Program Files\WebSite\z2.py" -D I have read mentions of the -D being a default debugging setting which may need to be turned off. How do I turn it off? When I put any of those strings into the address area of my web browser, windows wants to know what program it should use to view it. I also ran across an article which suggested one may need to create a HOSTS file in the windows directory. I don't know how to do that, but I follow directions very well. During my latest installation of Zope I told it to run as a win32 service, if that matters at all. I uninstalled Zope and reinstalled it twice to try to get it to work - once choosing the manual option instead of the win32 service option. I have a DSL connection and I don't have any firewall programs running (I did have Zone Alarm enabled, but turned it of so it wouldn't interfere). I've looked around on zope.org and egroups' message archives for hours and hours now, but have found very little relating to this problem. I may sound like a person who has no business trying to use Zope, but I use it at work everyday and love it. I can't wait to get it going at home. Any help will be unbelievably appreciated. THANK YOU!!!!!!!!!!!!!!!!!

This goes to show that there are many ways to do cool things in Zope. Everybody has their own way of doing something!

How do you reach the conclusion that editing either the sole copy of standard_error_message in the server tree or positioning an edited version of standard_error_message at a strategic point in the server tree to affect error handling below it is creating the unmaintainable mess you are talking about? If that is the case then I suspect there are a lot bigger problems extant on most Zope servers. If DTML is such a disaster then a whole lot of people are a long way along the path to oblivion by now. Hell of a time to tell us it was all a big mistake. >No, it doesn't feature in any paper books currently published (well, that's >actually not true, it's in at least one or two of the Zope books I've >seen) but >that's 'cos they were all written about 6 months ago.

I doubt anybody posting to this list is getting paid for it. If what I say in a post is wrong then I suggest you EXPLAIN why. Remember you chose to express a value judgement with your *vomit* comment, not offer a fact. Hell I'll happily unsubscribe myself than get that sort of "help". The alternative you offered involved writing a python script and a page template and maybe doing a Zope upgrade as the alternative to using some simple DTML. The new orthodoxy may say that is better but I'm some way from being convinced of it. _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Can we have spamassassin installed as a front-end to the zope lists?
by bruce＠perens.com 19 Feb '02

Can we have spamassassin on the Zope lists, please? My copy is correctly flagging spams to the list, meaning it would have caught them. It's free software, and seems to be very well thought-out. Thanks Bruce
