Refresh adds objects to Add list again
by Kevin Dangoor 20 May '00

20 May '00

Hi, I'm working with a very simple Product. Whenever I Refresh it, it shows up an additional time in the Add list. Is this expected behavior? I don't think I'm doing anything odd at all in the __init__.py or in the product itself. The __init__.py consists of basically just a single context.registerClass...

yet another LOCAL FS question
by Tom Scheidt 20 May '00

20 May '00

I want to use this: <dtml-call "manage_addImage(id=REQUEST['id'], file=REQUEST['file'])"> <dtml-call "RESPONSE.redirect( URL +'/success_html')"> but have the images placed into a folder in Apache. Can I send them directly? I have a local fs in the same folder as the above doc, should i send the images there, will the really end up in Apache?

Using ReportLab with Zope
by Richard Folwell 20 May '00

20 May '00

To sound out what, if anything, other people are doing in this area: I am interested in using ReportLab with Zope, to provide an improved printed version of web-published documents. What I want to do is fairly straightforward, to create a PDF file with: - a title/cover page with control information - a table of contents - the body of the document, with a technical document style header and footer (title, docref, revision, date, page x of numpages, etc) Indexing would be nice, but that involves much more complexity and is outside the scope of what I need right now. Currently I have documents published from Zope, sourced either as HTML (DTML documents) or XML, with the intention to also produce documents whose content will come mostly from a database (clearly straightforward in Zope). I think what I need to do is find some way of re-directing the output from Zope (what would normally go to the browser) to an external program, which uses ReportLab to generate the PDF file from the HTML stream, and returns the location of the file to Zope to pass to the browser as a re-direct (so the browser gives the user the option to view or download the PDF file). Is this correct? Is anyone already working in this direction? Any hints or tips? Richard

Hi, Is it possible to detect the top folder in dtml? I means I would like to prevent squishdot to show the ../ when it is already in the top level. Rgs, Kent Sin --------------------------------- kentsin.weblogs.com kentsin.imeme.net

How to use WebDAV?
by Richard Folwell 20 May '00

20 May '00

I am trying to use WebDAV (so far under Win98). IE5/File/Open(check "Open as Web Folder") - "http://localhost:8080" So far so good. IE5 opens a folder with the Zope files and folders visible, and I can navigate through the folders. However it is not clear how to work with files. Right-clicking on a file gives potentially useful options to Open or Send To. Open simply renders the file as if served normally through Zope, Send To does nothing - I tried sending to a plain text editor (PFE), my favorite HTML editor (CoffeeCup) and NotePad. Nothing happens. What am I doing wrong? Thanks, Richard

Zope/Apache Image Catalog
by Tom Scheidt 20 May '00

20 May '00

Hi I want to be able to upload images into a folder on Apache using a form page in Zope, and at the same time have the ids cataloged with keywords into a ZCatalog. Basically, to be able to search on keywords and have the related images displayed on a page. Does anyone have any recommendations, or know of any examples of this? Thanks in advance.

Sorting dtml-in with properties
by Adrian Esteban Madrid 20 May '00

20 May '00

Can you do a sort in a dtml-in by a propety of the object? What I want to do is sort the documents in a folder by a fixed number set in a property of that document. I tried something like this but it didn't work. <dtml-in "objectValues(['DTML Document'])" sort=order> Any ideas how this could be accomplished? Adrian

I think a lot of people, myself included, have had problems trying to clone objects inside of new ZClass instances. This sounds like the problem you're having. I haven't heard of a simple solution to the problem. John Morton talked about a possible workaround in a previous posting. Don't know if this will work for you, though.

I have seen a couple of cases > where I refactored code like that into a new method and then things got simpler. Tried that - I in-lined it on the list for brevity's sake. The problem is definitely with manage_clone not wanting to be used on a thing inside the transaction that creates that thing. ------------------------------------------------------------- End previous post
