ZClasses & UserFolders
by Tim Cook 03 Oct '00

03 Oct '00

Is there a reason I can't add a UserFolder (and subsequently users) to an instance of a ZClass that is sub-classed from Folder? I do not get any errors. But the acl_users folder is not in the instance and the user gets added in the next acl_users up the aquisition chain. -- Tim Cook -- Cook Information Systems | Office: (901) 884-4126 8am-5pm CDT * It's easy to stop making mistakes.

On low colour machines (256 or even 16colour) some colours are reserved for the system GUI so that you can match the 'theme', leaving you with fewer than the full capacity of the display you are using. Admittedly, since most people these days are running 15bit or higher colour depths, and non-paletted video modes, for the majority of users this isn't a problem. (Thus my 'lowest common denominator' comment.) The only other possible reason I can recall is that some of the 'named' colours are not supported by all browsers, or are not interpreted the same. > cheers, > > Chris Have a better one, Curtis

You need to select *Use Database Methods* on your ZClasses *Permissions* view, and then select each ZSQL method you create and map *Use Database Methods* to *Use Database Methods*. I haven't really groked why it's that hard, but it works. -Michel

Re: [Zope] ZopeTime().Date() confusion

"ZopeTime()" returns a "DateTime.DateTime" object. Such objects can be substracted giving the difference in days. This means, you can use: <dtml-call "manage_changeProperties(last_updated=ZopeTime()"> to set "last_updated" and <dtml-if "ZopeTime() - last_updated >= 1"> to check that the last update is at least 1 day ago.

As several people on the list pointed out, ZDebug is incompatible with "sendmail" (at least some ZDebug versions). Dieter PS: I do not like Mime mails in this list, because the stupid mailman installation discards Mime headers in the digest. As a consequence, my mail reader is unable to decode such messages :-(

RE: [Zope] FYI: Python product tutorial updated
by Darcy Clark 02 Oct '00

Brian, thanks for the reply ... I am currently more hopeful and feeling a little better about the amount of time and effort that I have put into Zope; knowing that the Zope book is coming also helps a lot. As someone else on the list replied, the obscurity problem will be partially solved with the book and others that will hopefully follow. I am in particular looking forward to some case studies that show how to use *and* why you should use some of the more complex Zope functionality. After being immersed in Zope for so long (about a year), I decided it was time to take a survey of the other tools out there - after doing a quick survey, I came away still unimpressed with most of them. I still think Zope requires more conceptual understanding (Zen?) that the other tools, but I'm still convinced that these concepts, many of which I am still yet to fully understand, offer far deeper and more elegant solutions to web development problems than the majority of the other tools. It's going to be tricky to achieve "optional complexity" - but that is exactly the nature of Zope. There are several levels or layers of Zen - after reaching each layer new potential ways to solve problems become possible. For instance, I know enough DTML and SQL to implement most of the functionality that I need and I have been writing my own ZClasses also. But I don't yet fully grasp the full possibilities of the Catalog, and Python/External Methods and I have had no luck getting any of the alternative User/Membership systems to work for me. These latter concepts/tools constitute my next level of complexity. Anyway, that's just my 2 cents ....

Reusing images from properties menu
by Mateos, Luis 02 Oct '00

02 Oct '00

Hello all! I'm trying to reuse property values to add images dynamically. In other words, when selecting values from a multiple selection in the properties menu, like English, French, Spanish..., will add the respective image flag into a search results page for example. At times, it could be more than one image... I tried to use "dtml-var image" as a value and it didn't work, then i tried using the "img src" tag and it work using a string but it didn't when using a multiple selection. Could somebody feed me on how to reuse images from the properties menu? Or whether there are some other better options to get the same job done?! Thanks in advance, Luis
