Using PropertySheets
by Erich Seifert 19 Sep '00

19 Sep '00

Hi everbody, I've played a bit with the PropertySheets interface and I wanted to create two Stylesheets. Everything works fine, but ... * I don't get the management tabs in the propertysheet/manage method. Perhaps a permission problem? * I can't pass a default value to a tokens property. How to? * I can't pass a default value to a boolean property. How to? Could someone please give me some example code or hints? Thanks in advance Eric

Does anyone on the list know how to change the getUserNames Python method to return a list of names instead of a list of objects? The code in question is this: user_ids=self.UserSource.getPersistentItemIDs() names=[] for i in user_ids: names.append(self.getItem(i)) return names Thanks, Michael Bernstein

Re: [Zope-dev] Custom dtml tag
by Brett Carter 18 Sep '00

Andy - looking up 'this' in a dtml method or document won't work unless you expose it in your python product/tag definition. I'm talking about getting 'this' inside a dtml tag that I have defined myself (i.e. <dtml-foobar></dtml-foobar>). If you want 'this' available in dtml, write an external method and just return 'self' def this(self): return self -Brett >>>>> "Andy" == Andy McKay <andym(a)activestate.com> writes: Andy> Really?

Adding functions to _
by Itamar Shtull-Trauring 18 Sep '00

18 Sep '00

I'm using CVS Zope, and I want to add a function of mine to _, so I have the following code in a Product's __init__.py: from log2vis import log2vis from DocumentTemplate.DT_Util import d d["log2vis"] = log2vis However, when I call the function, I get an error about DocumentTemplate, from which I discovered that when I call _.logvis('a_string'), instead of the string being passed as the first parameter, _ is passed as the first parameter to my function, forcing me to truncate it when calling log2vis: from log2vis import log2vis from DocumentTemplate.DT_Util import d def log2vis_wrapper(*args, **kwargs): return apply(log2vis, args[1:], kwargs) d["log2vis"] = log2vis_wrapper Any idea what could cause this strange behaviour? it doesn't happen for other functions inserted into _ in DT_Util.py. -- Itamar S.T. itamar(a)maxnm.com Fingerprint = D365 7BE8 B81E 2B18 6534 025E D0E7 92DB E441 411C

This is exactly what Jim came up with when we were presenting this idea. In fact, I like "asset" better than "component". IMHO the "asset" tag should always be generated by the server, not by a designer, so that it can contain the full physical path to the target object. > The tricky bit is managing UI handling for what happens when they save > their page.

When a designer saves the page back to the server, it might contain pieces from 10 different places. My initial reaction is to say that the only assets the server should accept are the assets located within the target object. Shane

Can ZPatterns Plugins be used separately?
by Kevin Howe 18 Sep '00

Hi, I'm wondering if it is possible to use ZPattern Plugins in a non-ZPatterns Product? Allowance for Plugins would be a very useful feature in many applications. kh
