I already used the things in AlexR's howto but still he uses fmt or strftime() and that is the problem. AlexR claims the base is GMT though (the Zope developers said the base-time was UTC). Nevertheless this is a problem... I'll try to chunk it in the collector once more with a bit more explaination. Thanks for your help.

document_src()
by Ronald F. Tagra 24 Jul '00

24 Jul '00

Hi, I am still new w/ Zope and trying to read and execute the tutorials and documents. Here's my first ever question. I have tried the dtmlObject.document_src() to view the source code of the script but it has error that says something like there are 3 arguments required..but in the document is just document_src(self). Thanks. Best regards, Ronald _______________________________________________________ Say Bye to Slow Internet! http://www.home.com/xinbox/signup.html

ZClass tutorial
by Firestar 24 Jul '00

24 Jul '00

Hi, some thoughts(and frustrations) from a newbie having his "first time" with Zope. The documentation needs a lot of improvement. Since October last year, there's still only ONE chapter(which is on ZClasses) in the Zope Developer's Guide?? Are there any more chapters forthcoming? Or do i have to fork out money and purchase the commercial version one?:( (And don't refer me to ZDP, please...) As for the "Zope Content Manager Guide", the examples are easy enough for newbies to understand, but some of the screenshots accompanying the examples are not 'consistent'. Perhaps DC can do some proof-reading there. As for the DTML reference, i felt "lost" after reading a few sections. At first, I thought it would be as easy as when i first read the PHP manual, but somehow it doesn't seem 'user-friendly' enough. Maybe i will try it again after i have read the rest of the Reference Guides. I'm not an expert in web development, and could not really pick up new "technologies" fast. But i still remembered learning PHP was not that difficult; the manual is comprehensive, easy-to-use and tutorials contributed by other websites really speed up my learning process. I understand that Zope is a different thing altogether from a programming language like PHP. I have yet to read up the Z SQL Methods User Guide, but from the docs that i have read so far, i still feel lost as to where and how to start building an 'advanced' website, e.g. converting my current PHP/MySQL website to Zope. Someting is missing here... Perhaps the Reference Guides could add more explanation and details, instead of just "click here and you will see this" kind of instructions. OR give more complex (real-world)examples, like building an e-commerce site(with sessions, cart & authentication). sigh...i foresee a rocky road ahead for this newbie to master the 'Zen' of Zope. Hopefully it's not a long one:( regards, firestar ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup

Datebug?
by Peter Arvidsson 24 Jul '00

24 Jul '00

I have encountered a strange and irritating problem. As I live in Sweden we use timezone 'GMT+1'. I have a form like this: <dtml-var standard_html_header> <form action="a"> <input type="text" size="15" name="date:date" value="<dtml-var ZopeTime fmt=%Y-%m-%d>"> <input type="submit"> </form> <dtml-var standard_html_footer> And when I press submit I come to this page: <dtml-var standard_html_header> <input type="text" value="<dtml-var date fmt=%Y-%m-%d>"> <dtml-var standard_html_footer> The input field are correctly displaying the date (in GMT+1) but when I submit the form and use the "fmt" the date is displayed with a decrease of 24 hours. Like if I write 2000-07-21 in the input-field the next page will display 2000-07-20. I I dont format the date on the second page the same date will be shown. It cant really be a timezone issue because it is decreasing the date by 24 hours and I only live 1 hour from GMT. The date on my computer and the server are correct. Does someone knows why this happens when I use "fmt" or is this a DateTime bug?

zcatalog and squishdot newbie question
by Sean Kelley 24 Jul '00

24 Jul '00

I have created a catalog and added my squishdot site to it. However, when I go to look at the catalog contents there are no squishdot articles listed (the suishdot site object is listed though). When I run a search for a keyword that I know is in the squishdot object, I get no matches (but do when I search for other non-squishdot keywords). I thought this may have something to do with running squishdot 3.1 so I upgraded to 4.1, reindexed and still nothing. What could be the problem? I heard somone say something about your catalog cataloging itself (mine does)- should it do this? I tried removing it but nothing. -- Sean Kelley

re: Meta Type Registry

Andrew Kenneth Milton wrote: > > Is there a Product Builders meta-type registry somewhere? > > I can see things getting messed up in the near future as the number of > products proliferates and meta-types start to clash. I just tried adding a new ZClass in a new Product in my Zope 2.2 final installation. The multiple-selection widgit for choosing the base-classes has all the available meta-types prefixed with the name of their product, followed by a colon. For example, here's the list I get: AccessControl: User AccessControl: UserFolder OFS: DTMLDocument OFS: DTMLMethod OFS: Folder OFS: File OFS: Image ZCatalog: CatalogAware ZCatalog: ZCatalog ZPatterns: DataSkin ZPatterns: PlugInBase ZPatterns: PlugInContainer ZPatterns: Rack ZPatterns: Specialist ZClasses: ObjectManager So, it looks to me like the problem of meta-types clashing is taken care of, at least in principle. I note that the management screens' "add" drop-down list doesn't have the "product:" namespace qualification, and I guess that's where the problems lie. I doubt this would be much of a problem to patch, and it probably counts as a bug, if anyone is passing the Collector in the near future. Now, we might want to consider a product naming registry to address the problem of product names that clash... -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

An observation about manage_* methods
by albert boulanger 24 Jul '00

24 Jul '00

This has a question to it if I am not overlooking something. I often want to design dtml_methods that allow the end user to manage content under his control. An example of a typical manage method that you often see is like: >From TinyTable.py: def manage_editData(self, data, REQUEST=None): """Change item data""" self._rows = map(self._FixRow, ImportExport.ImportData(data)) self._n_rows = len(self._rows) self._GenerateIndex() return self.manage_editedDialog(REQUEST) Now there is an assumption in this code that the editing context that this is being called from is some manage_ method, hence returns like "return self.manage_editedDialog(REQUEST)". This is annoying if you are writing a user-managed content method that does not wants the user to see the manage interface because eventually it goes to one with such returns. Instead, I would like to have control on where he/she returns (often to the method I wrote or to index_html). I could do a <dtml-call "RESPONSE.redirect..., but the return self.manage_editedDialog(REQUEST) gets in the way. Am I overlooking something or is this a weakness in this design pattern for management? I could wind up making my own version of manage_editData that does not do the return self.manage_editedDialog(REQUEST). (I know some code at least conditionalizes this to the presence of REQUEST.) Thoughts? Ideas? Regards, Albert Boulanger aboulanger(a)ldeo.columbia.edu
