[Q] Anonymous User fails authentication ...
by Darran Edmundson 29 Nov '99

29 Nov '99

Can someone explain the following? I create a method in my ZODB root containing the following DTML: <dtml-var standard_html_header> user: <dtml-var "AUTHENTICATED_USER.getUserName()"><br> can view: <dtml-var "AUTHENTICATED_USER.has_permission('View',_.getitem('id',1))"><br> <dtml-var standard_html_footer> If I run this snippet for a logged in user, I get: user: dee124 can view: 1 However, for a user who has not logged in, I get: user: Anonymous User can view: 0 even though the ZODB root shows that Anonymous has "View" permission. Is this a bug in Zope? Cheers, Darran. -- Darran Edmundson [Darran.Edmundson(a)anu.edu.au]

DateTime misfeature
by Stephen Pitts 29 Nov '99

29 Nov '99

According to lib/python/DateTime/Datetime.py: DateTime objects may be converted to integer, long, or float numbers of days since January 1, 1901, using the standard int, long, and float functions. However <dtml-var "_.float(ZopeTime)"> generates a TypeError. Am I I doing something wrong, or should this be entered in the Collector? -- Stephen Pitts smpitts(a)midsouth.rr.com webmaster - http://www.mschess.org

It has worked for me in every Netscape version on Win 9x, I have never tried it on any of the *nix versions, however.

How to concat values in a list?
by Shalabh Chaturvedi 28 Nov '99

28 Nov '99

I want to have the following on each page: You are here : _Home_ / _Subfolder_ / _Page_ Where each of the components is a link. The dtml-in tag lets me iterate over PARENTS but how do I concatenate with each itereation ? I've seen that Zope shows this in the management screens. Is this some built in function? Thanks, Shalabh

How can I restrict the folders that a Z-Class can be created in? Also, I've subclassed from Folder to create a folderish Z-Class; how do I control what can be added to it? -- Stephen Pitts smpitts(a)midsouth.rr.com webmaster - http://www.mschess.org

[ANN] FSSession 0.1.0
by Pavlos Christoforou 28 Nov '99

28 Nov '99

FSSession 0.1.0 is available at: http://www.zope.org/Members/gaaros/FSSession This is a module that stores Session information on the filesystem similar to Anthony Baxter's SQLSession. Installation instructions and simple documentation are available at the above URL. Examples of usage: <dtml-call startSession> <dtml-call "FSSession.set('expensivemethod',expensivemethod())"> If expensivemethod returns a list you can then retrieve it in a future session by: <dtml-in "FSSession['expensivemethod']"> <dtml-var sequence-item> </dtml-in> Enjoy Pavlos

non-web based zope front-end?
by Arjan Scherpenisse 28 Nov '99

28 Nov '99

Hi all, Maybe this is a stupid question, but i was wondering if there is a front end for zope's management screens which is *not* web based. I would like to work with it because i run linux and netscape, and netscape has its bugs and random crashes, and the procedure of editing - committing - reloading - editing is way slower then just pressing ctrl-s in a text editor... If it doesnt exists, i am interested in writing such an app, based on python/gtk/libglade, and maybe gnome. I don't know much about Zope's internals yet, but i'm a fast learner :-) Please let me hear what your comments are on this subject. greets, -- Arjan Scherpenisse, A.Scherpenisse(a)zap.a2000.nl ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Hi, MS Outlook just gave me a signature virus"
