RE: [Zope] filename extension

Perhaps I am wrong here, but couldn't one just use indirect variable lookup within the expression to access the method. There has got to be a way to use _.getitem for this purpose inside the <dtml-in>, since by default, it doesn't automatically render the method, but I'm not sure how one would pass the param to the method? Anybody have syntax that would work?

Re: [Zope] LoginManager with SQL and Skinscript: adding properties to propertysheet propertysheet

You may have noticed my silence on property sheets... At first, I didn't expect to use them, because I expected only members to edit their "properties" and I'm certainly not going to expose the standard Zope management interface to them. After going through the latest PTK sources some more, it looks like I may try using them after all. In either case, the important things to remember are: - The actual property data isn't stored in the ZClass or its property sheets, and the Skinscript code makes the ZClass "property" attributes have values with or without property sheets, and - The ZClass instances are ephemeral -- nothing is expected to store them for any length of time (though they may be cached). > I created LoginManager:LoginUser subclassed zclass def for a user with > a propertysheet Basic. > > It had properties password and email.

Is there a > way around this problem? I think you'll have to delete the whole ZClass and start over :-(. This shouldn't be too much of a pain because you shouldn't have any instances to worry about. If you've written custom methods, you'll want to copy them someplace before deleting the class. Hope this helps, Dan Pierson

zclassReverse problem
by Bill Welch 08 Jan '01

08 Jan '01

I get back exactly nothing, no 'Not Found', no classes/attributes. I believe that I've installed correctly. When I ask for a product that doesn't exist, I get a traceback that starts in Extensions/zclassInfo.py. I've tried in on Membership, LoginManager, ZPatterns, Poll, Etailer, and zCommerce. Zope 2.2.2, linux. Bill.

Newbie Questions
by Alex Reid 08 Jan '01

08 Jan '01

I am finally starting to make some decent progress with Zope now... more and more I think to myself ... "I wonder if...." and most of the time I am pleasantly suprised when it works! A couple of quick questions: - How would I display the value at a variable whose name is stored in another variable? In Perl this would simply be a double dollar type of affair $name = "Alex"; $myvar = "name"; print $$myvar; - I am creating a 'form' method so I don't have to create separate forms for INSERT and UPDATE actions. This works, only how do I tell Zope to ignore the fact that <dtml-var company_id> doesn't exist when in INSERT mode? It is there in the value="" parameter for the edit mode to pre-populate the element. Thanks in advance Alex

Re: Raise a Login Dialog
by Chris McDonough 08 Jan '01

08 Jan '01

Michal, Please use the Zope list to ask questions, thanks. The answer is somewhat silly. When you call this method, and you enter authentication credentials, Zope tries to render the method. Rendering the method raises an unauthorized. Then you enter your credentials again. And it raises unauthorized again. Etc. The purpose of raising unauthorized here is to clear your credentials from the browser. If you hit OK on the dialog (without entering any username or password), and then visit *another* method, you will be able to log in as a different user.

NEWBIE: Versions
by Andy Gates 08 Jan '01

08 Jan '01

Hi folks, Thanks to your help a few months back, I eventually got my first big Zope site up. Now the marketing droids have let it mature and come back to me with a laundry-list of tweaks and changes. 'Tis time, think I, to use versioning: keep the live site running and work on a version with all changes, let the droids assess it, and then roll it live in one chunk. Now, how do I do that, then? ---------------------- Andy Gates, Learning and Research Technology Andy.Gates(a)bristol.ac.uk - ICQ#74362415 http://www.ilrt.bristol.ac.uk
