Hi , I have some problems wityh Zope. When I use : <dtml-with filetti> <dtml-var someobject> </dtml-with> I received the Zope error: ############## ... ... File /usr/lib/zope/lib/python/DocumentTemplate/DT_With.py, line 132, in render (Object: filetti) AttributeError: __call__ ############## "filetti" is a folder at the top folder ( /) If I copy filetti in the "current" folder , will work but is not what I want ( more than one objects are using this) If I use: <dtml-with "PARENTS[-1]"> <dtml-with filetti> ... </dtml-with> </dtml-with> I get the error, too. Has someone any idea? Marcel

Learning DTML - an addition to ZBook
by Eron Lloyd 04 Apr '00

04 Apr '00

Hey hey hey! Ok, I've decided to work on a thorough study of DTML, and add it to ZBook. I don't know how well it will flow at first, but that's the beauty of write, edit, rewrite, revise :-) Anybody that wants to look at what I wrote feel free to contact me. Currently, I've come up with somewhat of a structure: Learning DTML ---------------------- 1.) Common Questions [Q.] What is DTML? [A.] Zope's scripting/reporting language used to create/manipulate(process?)/display Web objects. [Q.] How do I use it? What do I use it for? [A.] DTML is a powerful but simple language you use to create dynamic Web applications in Zope. It can written in documents or embedded from a separate script (more explanation). It can be used to: - create/insert variable data - format date/time information - "if" statements (selective actions/conditional insertation) - "in" statements - batch processing - display objects - name/expression evaluation - expression handling - comment code - ...? [Q.] It's a programming language? I don't know how to progam! All I know is HTML. I don't have time to learn Python. Can I still learn DTML? What's the best way to approach it? [A.] ...? There should be good examples of each dtml tag in action, explanations, advanced usage, case studies, and exercises for users to step through. 2.) Using DTML for real world tasks [Q.] How do I... - create/use variables? - add the date/time to my site? - create a feedback form? - search through Web objects - ..? I hate to admit it, but we need to take a "DTML for Dummies" approach if we want to be able to do this effectively. Although I've volunteered to spearhead this effort, I feel even I know very little about the language (although this will also help me to start out very, very basic). There are many questions/answers that need to be formulated, and I would like to encourage a general discussion of the aspects of learning and using DTML. I will collect all responses, and start to mold some structure out of them. All newbies are heartily encouraged to ask ANY questions about things they don't know or problems they've had, and all Zope guru's please give us some gems of wisdom. I want this to be an exhuastive "study" of DTML, not an argument on what's wrong with the language, or what's wrong with the current documentation, etc. Positive feedback only, thank you. Tom: I have a beginning draft; what should I do to add it to the ZDP site? Thanks in advance to all that choose to participate in helping this DTML manual. Eron Lloyd

new local file system release
by Jonothan Farr 04 Apr '00

04 Apr '00

I originally sent this announcement on Saturday, April 1. However, it was intercepted by the list admin because I made the mistake of trying to bcc the zope list as well. Don't make this mistake! Don't let it happen to you! ;) -----Original Message----- From: Jonothan Farr <jfarr(a)real.com> To: zope-announce(a)zope.org <zope-announce(a)zope.org> Date: Saturday, April 01, 2000 2:24 PM Subject: new local file system release Greetings. Today I'm announcing not one but two new versions of the Local File System product. Although we'll call these the April Fool's Day releases, no they are not a joke. Version 0.1.8 adds simple file uploading. It also fixes a problem with Image and File objects by setting the modified time of the ZObjects correctly. This also enables browser caching to work correctly. Version 0.1.9 adds support for adding, editing, moving, copying, renaming, and deleting local files through the Zope management interface. This is all highly experimental and potentially dangerous. This is why I've chosen to release the two feature sets separately. You would have to be absolutely insane to run this version on a production server. Please note also that the license agreement specifically states that I am not responsible if you shoot yourself in the head with this thing. That being said, please feel free to try it out on your development/test servers and get back to me with any problems you may find. As always, please feel free to contact me at jfarr(a)real.com with any comments, questions, or bug reports about the Local File System product. The product is available at: http://www.zope.org/Members/jfarr/Products/LocalFS --jfarr

RE: [Zope] date-time manipulation
by Marcus Collins 04 Apr '00

04 Apr '00

Hi, Your code is syntactically correct, but the ZopeTime() function has sub-second precision. The result of subtracting one date object from another is a floating-point number of days. Take the integer portion thus: <dtml-if "_.int(ZopeTime() - created) == 14"> <p>Time's up! </dtml-if> and you've got the number of full days that have elapsed. There's a wealth of information on DateTime objects in lib/python/DateTime/DateTime.html hth, -- Marcus > -----Original Message----- > From: mindlace [mailto:mindlace@imeme.net] > Sent: 04 April 2000 03:09 > To: zope(a)zope.org > Subject: [Zope] date-time manipulation > > > Zopistas, > > I have a date-time property called "created" in a dtml > document.

Re: [Zope] Simple form Problem
by Cornelis J. de Brabander 04 Apr '00

04 Apr '00

Make all buttons of type 'submit' and give each button a distinctive name. In your action method you can check which button was clicked, because the value of your REQUEST.form has a 'submit' key that equals the name of that button. <dtml-if "submit=='button_name'"> cb -----Oorspronkelijk bericht----- Van: Baker, Dennis (sjmr) <DBaker(a)CHW.edu> Aan: 'zope(a)zope.org' <zope(a)zope.org> Datum: maandag 3 april 2000 23:27 Onderwerp: [Zope] Simple form Problem >I am trying to build a form which has a dropdown at the top, and a bunch of >buttons below with different functions which to do with the list item.

Re: [Zope] How to emulate browser back button

I had a similar issue from within an external method. I strongly suspect that the way I solved it is not the way to do it:-) I used REQUEST.redirect('next_page?back=this_page') return REQUEST in next_page there is something like: <a href="<dtml-var back>">Back</a> What is the proper way to do this with Zope? Sean,
