Variable substitution in an object name
by Lou Scalpati 16 Jun '01

16 Jun '01

I can substitute a property name for the base of an object call with: <dtml-var expr="_[wrap].index_html(_.None,_)"> where wrap is a property that refers the name of an object But I have not been able to figure out how to use a variable to substitute the method (in this case index_html but could be index_xml or index_wap) If I use the above methodology - I get looping login boxes where it won't authenticate and when I hit cancel I get a traceback in file DT_Util.py line 142, in careful_getattr. Is there a way to do this?? Thanks Lou

A TinyTable problem
by Ricardo Newbery 16 Jun '01

16 Jun '01

I'm having some trouble with a TinyTablePlus logging routine. I have a nearly identical setup on another Zope instance but for some reason I can't get this one to work. The TinyTable is in a subtable called 'log' along with a DTML method called 'usercnt' I put the following in the standard_html_header: <dtml-let usercnt="_.getattr(log,'usercnt')"> <dtml-call usercnt> </dtml-let> The usercnt method does a few different things but I've narrowed the problem down to these couple of lines: <dtml-unless logtable2> <dtml-call expr="REQUEST.set('logtable2','users')"> </dtml-unless> <dtml-with log> <dtml-call expr="_.getitem(logtable2).setRow(name=username_forlog,count='1')"> </dtml-with> The TinyTable is successfully updated but I always get an error page with the following traceback:  So, any ideas what's wrong?

Hi there, Does anyone know where there are any Zope severs that the public can use to upload there web sites to? I've tried looking on the Zope webpage but can't find any information about where to find Zope severs to upload the pages you've created. Any ideas? Cheers Alan

Re: [Zope] Checking for a boolean property value in DTML

I had tried that to. It didn't work either. Here is why... I was running the code from an DTML Document, not a DTML Method. However, once I put the code in a DTML Method, it still didn't work. I think that part of the problem is that the scope I'm working with by calling the code from a DTML document, and then look for all of the DTML documents in the folder, is misplaced. What I may need is to call the parent object (a folder) to look for that bit of code... Something like <dtml-in expr="Parent.objectValeus('DTML DOcument')" sort="decision_date" reverse> <dtml-if expr="document_type == 'case'"> Do something... </dtml-if> </dtml-in> Except that I don't have the parent parameter right. I don't remember how to call a parent object. Do you think that would solve the problem?

Okay, I moved all of this code into a DTML Method. Note, the DTML Method itself was called form a DTML Document. One of things I want to do is list other DTML documents that satsify a certain criteria in when someone wants to view the first DTML Document. Here is the code that works (in a DTML Method called from a DTML Document)... <dtml-if expr="title == 'Mental Steps Doctrine'"> Past first if<BR> <dtml-in expr="PARENTS[0].objectValeus('DTML DOcument')" sort="decision_date" reverse> Past the in<BR> <dtml-if expr="document_type == 'case'"> In the case.<BR> <a href="&dtml-absolute_url;"><dtml-var title></a><br> </dtml-if> </dtml-in> </dtml-if> Thanks to everyone who helped.

A boolean property either has the value '', or 'on'. <dtml-if prop_name> set <dtml-else> clear </dtml-if> This worked fine in Zope 2.3.1 -Randy > -----Original Message----- > From: marc lindahl [mailto:marc@bowery.com] > Sent: Friday, June 15, 2001 3:51 PM > To: complaw(a)hal-pc.org; zope(a)zope.org > Subject: Re: [Zope] Checking for a boolean property value in DTML > > > > > > From: complaw(a)hal-pc.org > > Date: Fri, 15 Jun 2001 22:32:18 GMT > > To: Dieter Maurer <dieter(a)handshake.de>, > complaw(a)hal-pc.org, zope(a)zope.org > > Subject: Re: [Zope] Checking for a boolean property value in DTML > > > >> complaw(a)hal-pc.org writes: > >>> I have a boolean property in a DTML Document.

Simple observer
by Peter Bengtsson 15 Jun '01

15 Jun '01

I'd like to add God to a folder. What I want is that for some reason (pseudo reason) that you shouldn't be allowed to create objects with certain ids in a specific folder. Perhaps a little product or something that just sits there and sniffs for manage_add* requests or something. One basic solution would be to create my own copies or addFolder, addImage, addSquishdot form and methods in which I have something like this: if REQUEST['id'] =='protectedid': print "not that id, it's not meant to be used" else: self.manage_addFolder(REQUEST['id'],REQUEST) But to handcode a solution I have to create my own version of all meta types, and I don't want that. I just want to put up an extra guard in front of the setObject() doings. What simple options are available for this? Peter
