User DB - accessing Authenticated User in Python - and the Zope Mailing list
by Paul Gresham 03 Nov '99

03 Nov '99

Hi, At MediaVisual Hong Kong we are looking to do a lot of the things that are available on the Zope web site, relating to the subscriber database, although the site we are building is a lesiure/lifestyle site for young asian's. Can you please help me with a few queries. The first is simple. Is the Zope Mailing list handled by Zope, or another package ? As we would like similar functionality. The second is relating to the UserDB. I never found any real good docs on it, but managed to get it all working, against MySQL. However I have found that if I log on as a subscriber, then go to the /manage section, I am able to change some, but not all things across the entire site!! I am also able to cut and paste most objects, although I cannot delete. Can anyone give me some pointers on what to look for. I have also found that if I know the URL to call a function and update a user, I can pass my own parameter across and change almost any existing users password etc. Lastly, I cannot quite figure out how to get the authenticated user inside Python, if I can get this, then my python code can stop the above problem should a user construct their own URL to change a password. Is this a sensible way forward, it seems that I need to authenticate at the Python level, as the data and methods are stored externally to Zope. Any user which has access to the function can construct a URL which will perform an update regardless of user, once we are in the UserDB Python code. Thanks for any help you can give Paul

Problem using EMACS FTP to Zope
by David C. Morrill 03 Nov '99

03 Nov '99

I have a couple of (I hope) simple problems using (Win32) EMACS ange-ftp support with Zope: 1) I want to use the '(setq efs-make-backup-files nil)' trick that's been mentioned previously, but being a total EMACS neophyte, I'm not sure what directory to put the '.emacs' file in. Can someone loan me a clue? 2) If I use ange-ftp to access a Zope folder, I get a nice 'dired' listing. But when I select a DTML document/method to edit, I get another 'dired' listing containing just the selected file. If I select the file again from the new 'dired' list, I finally get the document I wanted, but the name is listed twice in the path: once as a directory, and again as the filename. Needless to say, this prevents me from saving the file (even if I chop off the extra filename, I still get errors saving the file). Anyone have any idea why this might be happening? Thanks, Dave Morrill

pcgi,zope,apache

ok. i am trying to get apache to work w/ zope. with lots of help from #irc I've gotten it this far.. and I couldnt find any info in the mailing list about this. my whole site is zope and I am using apache. my rewrite rule comes out to be: RewriteEngine on RewriteLog /var/log/httpd-rewrite.log RewriteLogLevel 9 RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^(.*) /usr/local/apache/cgi-bin/Zope.cgi/$1 \ [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] the last line, of course is on one line (\ is not really there just signifying where following line should start). now what happens is crazy: when I goto www.mydomain.com/ I get apache (bad) when I goto mydomain.com// I get zope (good) when I goto mydomain.com/manage I get zope mgmt (great) I can traverse url's fine.. just the bloody index_html wont show up! why is it acting this way? its tired... err I'm tired.. very tired.. has anyone figured out how to get Zope workign w/ Roxen? is it easier than this? to get it to work when i just type mydomain.com/ and get Zope all hell breaks lose - the mgmt page gets files not found, etc.. that rewrite rule is essentially: ^/(.*) /usr/local/apache/cgi-bin/Zope.cgi$1 which doesnt do anything but give me zope on mydomain.com/ ok.. my stuff is working now (hmmmm.. being this late..)... oh well who cares. IT WORKS! definetly keep tabs on http-rewrite.log.. cool stuff.. sorry this msg went no where -- ~alan

The _searchable_result_columns method returns information about the indexes instead of the columns returned from a search. Also, the returned results do not support a _searchable_result_columns method themselves, which all other Searchable objects do.

idea - UserDefined Properties
by Jay, Dylan 03 Nov '99

03 Nov '99

Like a ZClass but smaller. Basically an object that ecapsulates something that is simple valued. It has a method for displaying an editor that can be placed inside a view of a property sheet. It has a rendering method. And it has a method to change and validate its value. This way something like a TinyTable can be embedded in a propertysheet and not have to a seperate object.

Permissions with object container ZClass
by Jay, Dylan 03 Nov '99

03 Nov '99

I have a ZClass that contains one TinyTable when its instanciated. I have a DTML method that queries that TinyTable. When I access this method using the manager role all is fine, however when I use Anonymous it asks for permission. I don't want to give the Anonymous user Query Tiny Table permission however if I give the DTML method proxy permission of Manager it says I'm unauthorized. How can I get this to work?

Accessing Class Attributes via a python Base Class
by Kevin Howe 03 Nov '99

03 Nov '99

I am trying to access the Class Attribute values (meta_type, class_icon, class_id, etc.) from a simple base class by doing the following: import Aquisition class myClass: def __str__(self): meta = self.classMetaType() return meta I've also tried: meta = classMetaType() return meta and : return self.getClassAttr('meta_type','') but none of these seem to work. How do you retreive these values? KH
