UserFolder Alternate Login
by dlee＠usol.com 06 Jan '01

06 Jan '01

Zopatistas, I need functionality that none of the UserManagers seem to address. I need to allow a user to elect to log in (and set AUTHENTICATED_USER) as opposed to have them access a restricted resource to trigger cookie authentication. I am essentially limited to GUF because it's the only thing I can install on my provider's system (I can't compile the LoginManager). Is there a way to allow the user to login at will, and still get AUTHENTICATED_USER set? There are no "restricted" parts of the site I am building (except for the management interface) however, I would like to generate dynamic menus (using hasrole) which allow users in specific groups (authors, members, etc) to have additional menu options. I'm hoping there is a way to do this... Thanks in advance, Darin Lee

emacs and zope
by Mehmet Yousouf 05 Jan '01

Hi, I am trying to get xemacs to use dtml tags (zope), I downloaded .dtd, .ent, .el files and can get it to go into "dtml-mode", but I can't get any of the tags to appear in the menus. I put the files in ~/Emacs/ (this is referenced in my .emacs file) it seems to find my public file, and the .el file as I do get into "dtml-mode". I tried putting the .dtd and .ent files in /usr/lib/xemacs/xemacs-packages/etc/psgml but still no luck. What am I doing wrong? Regards, Mehmet

newbie q -- 2.3.0a1, file object & precondition
by John Gerard Malecki 05 Jan '01

05 Jan '01

hi, i'm very new to zope and am trying to get familiar with the variety of mechanisms i can use. zope is indeed a very nice package! i am starting with version 2.3.0a1 (because it matches the book). i've not yet had success getting preconditions to work with file objects. i hope i'm not doing anything too bone-headed. here is what i have: in a folder i have file objects T and U. T has the precondition 'preco(1)' and U has the precondition 'preco(0)'. in the same folder (or above, it doesn't matter) i have the python script preco with the contents if r == 0: raise "preco" else: return r when i the manager or type in the URL directly i can view/download both T and U. i was hoping only T would be "visible". i'm not sure how to debug something like this. if you can tell me how i can debug this on my own that would be best. -cheers

SELECT COUNT(*) ZSQL method -> displaying results?
by Lee 05 Jan '01

05 Jan '01

Hi, I am having difficulty displaying the results from an SQL query: SELECT COUNT(*) FROM REGISTRY WHERE <dtml-sqltest classcode op=eq type="float"> When I call the ZSQL method from my DTML method and try and display the result (using <dtml-var count>) I get a rather horid, "This resource may be trying to reference a nonexistent object or variable count" error. My only thought is that because 'count' isn't actually a proper variable (i.e. a column name) it is handled differently. Can anyone see my error / offer advice? Thanks very much in advance. - Best regards, Lee -- Lee Reilly mailto:lee.reilly@ntlworld.com http://www.footkick.co.uk/lee

PoPy Problems
by J. Atwood 05 Jan '01

05 Jan '01

Linux 6.2, Zope 2.2.4, PostgreSQL 7.0.3, PoPy 1.4.1, ZPoPyDA 0.7.0 I installed the PoPy module and at the Python command line can "import PoPy' with no problems. I then untarred the ZPoPyDA and restarted Zope at which point I get (in the Zope management screen). ZPoPyDA Import Traceback Traceback (innermost last): File "/usr/local/zope/lib/python/OFS/Application.py", line 397, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/zope/lib/python/Products/ZPoPyDA/__init__.py", line 32, in ? import sys, os, Globals, DA File "/usr/local/zope/lib/python/Products/ZPoPyDA/DA.py", line 35, in ? from PoPy_db import DB File "/usr/local/zope/lib/python/Products/ZPoPyDA/PoPy_db.py", line 35, in ? raise "The PoPy module is not installed" The PoPy module is not installed There is really no more instructions on the site, in the INSTALL or README. If have installed and worked with ZPygreSQL before but was under the impression that it did not work with the newer versions of Zope and Postgresql. Thanks, J

You mean you want to use AUTHENTICATED_USER like a cookie, i.e. loggin in and every password authenticates? Using basic auth it might be a nice way to get cookie functionality without using cookies. You could write a custum method which triggers authentication and rewrite the method of GUF to always return 1. If someone wants to "log in", he could click on a link to this method. Maybe <dtml-unless "AUTHENTICATED_USER.getUserName()=='Anonymous User'"> <dtml-raise type="Unauthorized"> Logout!! </dtml-raise> </dtml-unless> You are now logged out! could be a starting point. If it is contained in standard_html_header it would force everyone to choose a user name, and in conjuction with the GUF-hack mentioned above he would always be logged in - well unless he decides to call himself "Anonymous User" (luck that this isn't coward ;). If you want to use cookies anyways, take a look at session manager or code it yourself and don't use hasrole. cheers, oliver

manage_editProperties Question
by Ronald L. Roeber 05 Jan '01

05 Jan '01

I have looked through the Zope book and other documentation, but still am unable to properly allow others to change properties in a product with a custom built form. Case in point, a product with a Property called contact which is a string The product changing method I am trying to make work contains the following def editProductInfo(self, newcontact): ... self.manage_editProperties(REQUEST=None,contact=newcontact) ... Which is not correct obiously since it generates the following error: Error Type: TypeError Error Value: unexpected keyword argument: contact -------------- TIA for helping someone so slow as myself...

SQL "editing"
by Alex Burton 05 Jan '01

05 Jan '01

Hello All, I'm quite happy, got MySQL + the necessary adapters running in no time. Imported tab-delimited text and enjoying Zsearches... Zope kicks ass! Now, i'm wondering if there's anyone who've done some work as to permit easy editing of records in SQL tables? What i have in kind is something like: - do a search -> a list of matches come up; - select a match -> a form comes up filled with the data, and a "submit" button - press submit -> SQL gets altered A bit like the "edit this page" philosophy, but for SQL records... Thanks! Alex.

Your method: def my_method(REQUEST): '''my_method interpreting *REQUEST*.form.''' form= REQUEST.form # this is a dictionary containing form # variables and associated values ..... If you like, you can directly use it as form action. But probably, you will wrap it into a DTML method: DTML wrapper: ..... <dtml-call "my_method(REQUEST)"> ..... Dieter
