It just does not have a (visible) name (the name is "__call__", which you cannot use in DTML as all names starting with "_" are private). You can just call it or use the "View" tab in the management interface. > I tried to write such a method myself - without success. <dtml-var expr="_.render(this())"> as a DTML method will do it.

Or do you want Zope to behave like a mail (SMTP) server? Look into the (searchable) list archive (maybe of zope-dev). There was a product that allows Zope to read in emails. You may look at "wordpilot", too. Dieter

Help files permission settings
by Farrell, Troy 26 Feb '01

26 Feb '01

I was cleaning up my permissions settings, and I've inadvertantley closed off the Structured Text Help Files. Symptoms: When a manager clicks the Help link in the upper right corner, a new window pops up. The Help tree on the left shows up as expected, however, the pages on the right are inaccessible and give me a login prompt. The superuser (or should I say inituser) can get the files. I'll try any suggestions as I do really find the help helpful :) TIA, Troy

Or equally well in a product? I would not call these low level methods directly (though it may work) but use the higher level Z SQL methods. This way, it would be ensured that the use plays well with Zope's transaction subsystem. Dieter

Re: [Zope] empty lines property value

I see this behavior in both of the > versions of Zope that we run locally -- 2.2.4 and 2.3.1b1. It's an implementation artifact: Python's "string.split('','\n')" returns "['']", as is probably correct as "string.split('a','\n')" should return "['a']". Dieter

approach for assigning ODBC results to fieldnames as variables?
by Bill Seitz 26 Feb '01

26 Feb '01

When you execute a SQL (select) query via ODBC and do a fetchall(), you get back a result set as a tuple (array). You can also ask for the cursor's description, which returns a separate tuple, the first column of which contains the fieldnames (or other labels calculated by SQL). Getting back an unlabelled tuple means that when you want to write out a table of results (with some individual handling of various fields, not just dumbly iterating over the columns), you end up with an ugly line like: Response.Write('<tr><td>%s<td>%s<td>%s<td><a href="matterEdit.asp?clientID=%s&matterID=%s">%s</a><td>%s<td>%s</tr>' % (row[0],row[1],row[2],row[1],row[3],row[3],row[4],row[5])) (this is a Python-via-IIS model, but would be similar under Apache, etc.). Is there a standard approach to assigning field names to columns, so that this output line could be changed to something like Response.Write('<tr><td>%s<td>%s<td>%s<td><a href="matterEdit.asp?clientID=%s&matterID=%s">%s</a><td>%s<td>%s</tr>' % (maxDate, clientID, clientName, clientID, jobID, jobID, jobName, totalHours)) or even at least something like Response.Write('<tr><td>%s<td>%s<td>%s<td><a href="matterEdit.asp?clientID=%s&matterID=%s">%s</a><td>%s<td>%s</tr>' % (maxDate[i], clientID[i], clientName[i], clientID[i], jobID[i], jobID[i], jobName[i], totalHours[i])) thx for your help... __________________________________________________ Do You Yahoo!?

You may look at the ZCatalog section in URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html Maybe, the Zope book, too, tells precisely, what options the ZCatalog supports. Dieter

It is not forseen to render them. You have several options: * make your objects folderish ZInstances and use DTML objects as complex property replacements. You will loose property defaults defined by the class * use a Python Script or External Method to explicitly convert your property string value into a DocumentTemplate Dieter

This is probably a bug. You can try to work around it with "local roles". Dieter
