Form validation
by Wayne Pascoe 14 Mar '02

14 Mar '02

Hi all, Quick question ... I want to do something that I can in Perl using Template toolkit and I was hoping that someone could point me at some code showing how to achieve this. When a user fills out a form and hits submit, I want the action page / method to check that all required fields are filled out and all filled out values are valid for the field. If there are any values that are not correct, I want to display the original form, with all fields that did have values prefilled and something like * Invalid date format Or * Required field In red under the field that is wrong or not filled out. Is anyone doing this and could someone point me at some code if there is some. TIA, -- Wayne Pascoe <wayne.pascoe(a)ehsrealtime.com> The price of freedom is eternal vigilance - Thomas Jefferson

detailed record display...
by Alexander Batzios 14 Mar '02

14 Mar '02

Hello. First of all I would like to thank everyone who replied to my previous question. Thanks for pointing out that it was called batching and was in dtml-in documentation. I did manage to split the results. However, I still can't figure out how to make the record details appear. As I told you, I want the list of the results to be clickable in a field (e.g. record field) and when a user clicks on that, the record details to appear. I've created an SQL method called sql_show_details and a Z search Interface called show_record_details. I have put "Rec" as the arguments in the sql_show_details method. Now, when I display the results I put the following entry in the results display form: <td><a href="show_record_details"><dtml-var Rec null=""></a></td> What I was hoping to achieve, is call the show_record_details interface with the Rec dtml-var as a parameter. The show_record_details interface calls the sql_show_details method to get the record. However, it seems that record 0 is returned all the time. I assume that it doesn't actually pass the Rec parameter for that specific row in the table. Is there a way I can do that? I tried experimenting with various alteration but nothing. In the docs, I've found <dtml-call> which calls a method passing all arguments, but it doesn't work from href. Thank you in advance, Alex

ZClasses under Zope 2.5
by Beat Zimmerli 14 Mar '02

14 Mar '02

Hi every body. I am new to Zope and I am trying to create a ZClass in order to use automatic cataloging. I am following the Zope book chapter 9 automatic cataloging. The creation of the ZClas "NewsItem" works fine, as described in the book under Zope 2.4.3 (running on NT 4). Unfortunately the same ZClass does not work under Zope 2.5.0 (Windows 2000). If I want to create a new NewsItem I get an error after having entered an id and clicked on add. Any one any suggestion? Thank you very much in advance Beat Zimmerli

SESSION and REQUEST variables
by Kevin Smith 14 Mar '02

14 Mar '02

I am storing a TransientObject based instance in a SESSION variable. What are my options for getting the REQUEST variable when calling methods on this instance from a page template? Looking at self.REQUEST doesn't seem to work and using 'python:obj.getData(request)' is very verbose. I would like 'obj/getData' to work, but it doesn't. Kevin Smith Kevin.Smith(a)theMorgue.org

You might find EasyPublisher interesting. It's rather a complete CMS-solution with (a integrated IE5.5/6.0 WYSIWYG-editor) than just a simple editor (it includes Zope). http://easypublisher.torped.se/english For simple editors you also have the grandfather of EasyPublisher IEMethod http://www.zope.org/Members/johanc/IEMethod/IEMethod Best Regards, Johan Carlsson torped strategi och kommunikation ab johan carlsson johanc(a)torped.se birkagatan 9 113 36 stockholm västmannagatan 67 http://www.torped.se http://easypublisher.torped.se

Subfolders in LocalFS
by Bogemans, Thierry [PRDBE] 14 Mar '02

14 Mar '02

I'm trying to get the content of a subfolder from a directory structure using LocalFS doing the following : <dtml-in expr="Pictures['subfolder1']['subfolder2']['subfolder3'].fileItems()"> <dtml-var id> </dtml-in> So far, everything looks fine... The actual problem is that I'm not able to enter a subfolder defined in a variable way. It works out fine when there is only one subfolder : <dtml-call "REQUEST.set('location','Summer')"> <dtml-in expr="Pictures[Summer].fileItems()"> <dtml-var id> </dtml-in> but what to do if we need a subfolder's subfolder ? We can try typing : <dtml-call "REQUEST.set('location','Summer/Vacation')"> <dtml-in expr="Pictures[Summer].fileItems()"> <dtml-var id> </dtml-in> to get the content of the Summer/Vacation folder... But this fails in ZOPE ! Can someone show me the light please. Thanks, Thierry

How to insert a DTML doc given its ID as a string?
by Bill Bell 14 Mar '02

14 Mar '02

Must be trivial. Can't find answer. 'thisWeeklyMain' is a Python routine that supplies the name of a DTML doc that _might_ exist in the current folder. I'd like to arrange to insert the DTML doc, if it exists, or an alternative doc, if it does not. Thanks for your help.
