MessageDialog with dtml?
by Peter Arvidsson 10 Aug '00

10 Aug '00

Is it possible to display a MessageDialog with dtml only? I have searched the mailinglist archives and found some postings about this but the instructions there doesnt seem to work. Maybe MessageDialog has been changed to 2.2 or something?

Here is how it looks: > > <dtml-with "newsEntries"> > <dtml-if "_.getitem(objId,0).approved == 0"> > <dtml-call "REQUEST.set('approved', 1)"> > <dtml-call "_[objId].propertysheets[1].manage_editProperties(REQUEST)"> ... You could save a line by calling this a little differently by using manage_changeProperties instead: change this: <dtml-call "REQUEST.set('approved', 1)"> <dtml-call "_[objId].propertysheets[1].manage_editProperties(REQUEST)"> to this: <dtml-call "_[objId].propertysheets[1].manage_changeProperties(approved=1)"> > So the updating of both of the products are done by <dtml-call > "_[objId].propertysheets[1].manage_editProperties(REQUEST)"> but when I > try to update pressreleases is says I am unauthorized. This is probably an ownership issue. Make sure the DTML method's owner has manager rights. In Zope 2.2 the user running a method takes on the security level of the owner of the method even if it is lower than that of the user. This is in order to prevent certain trojan horse type attacks. Good Luck, Casey Duncan

Importable Xron
by Peter Bengtsson 09 Aug '00

09 Aug '00

I want to use the Xron product but I don't understand how to use it. (http://www.zope.org/Members/lstaffor/Xron/) All this Zope Zen jargon makes me dissy. What I don't understand is where and why to put reschedules at certain places. Subclasses and DTML Methods...etc. Can you please include a importable zexp on the download page of Xron. I want to do one single simple thing for now. Send the <dtml-var webmaster> constant information about various site stats. These should be sent weekly or hourly or monthly. I also want to have more than one instance of Xron. Can somebody give me examples. Especially how you set the date and time. (I have no experience of cron and I live in GMT+0) Grateful, Peter Peter Bengtsson - OD Consultancy

In some weird cases, however, this might not be the case, e.g. if "squishdot" would not be derived from "Acquisition.Implicit". Dieter
