I know, I know. :) But how otherwise do I get you people to come out from hiding without posting a hack like that? :) GUF has problems and we have to face it. If a product takes a few days to install, if a product locks newbies up and send them into panic attack, it has problems. Please just look up past postings in the mailing list... headers like "Bad... very bad" and "GenericUserFolder has locked me out" are just heartbreaking. :) If I have time I'll find something better, or make something better. :) Evan: (1) When the the next version of Zope coming out? It fixes a tiny bug that I reported. :) Will it have a native feature like SiteAccess that you have mentioned before? (2) Could you describe briefly how the traverse machinery works in Zope? I'd like to take a look into it. Which Python files are involved? regards! Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

meaning error message
by Oai Luong 16 Mar '00

16 Mar '00

My postgres database tables are setup to have unique index therefore no duplicates are not allow. If duplicate occur the db will return an error. Problem is when i try to submit duplicate data to the db i get an ugly error message. Is there anyway i can output my own error message for example "this data exist on the db already, please do not submit again" ? I don't want that error message because user's won't understand what is talking about. thanks.

DateTime exceptions
by Curtis Maloney 16 Mar '00

16 Mar '00

Greetings, A workmate of mine has had this problem also, and now it's happened to me. I cannot catch exceptions from the DateTime object! My code: <dtml-try> <dtml-call "REQUEST.set('delDate','%s/%s/%s' % (delYear, delMon, delDay) )"> <dtml-except> <dtml-call "REQUEST.set('delDate',0)"> <font bgcolor="red">You have entered an invalid date.</font> <dtml-call "REQUEST.set('Error',1)"> </dtml-try> Now, from my understanding, this should catch ALL exceptions. So why, when i give invalid values (like -1) does ZOPE give me an error page? Is this some deficiency in the way the DateTime object handles exceptions? Or is there some funamental zen i'm not groking? -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>

Hi.. I just uploaded many files with load_site (thanks Itamar!), but I ran out of disk space while doing this. Seems as the last transaction corrupted the Database seriously. When I try to delete the folder where the errors are I get: Error Type: CorruptedDataError Error Value: The same with packing database. And when invoking Undo, i get something like: long int too long to convert Any ideas what I could do to repair my database and deelete the corrupted folders and start over again? Thanks in advance, Mario

Zclass subclassing Image - how to manage uploads?
by Marius Kjeldahl 15 Mar '00

15 Mar '00

I've seen numerous postings about this, but so far I have been unsuccessful in successfully subclassing the Image with my own ZClass (called VProduct for this case). Here's what I have managed to do: * Create my new VProduct ZClass with Image as a base class * Add a couple of new simple (string) properties to VProduct * Modify the VProduct_add and VProduct_addForm methods so that my new properties gets asked for and filled in (and using the system clock to generate unique id's) This seem to work great, and I can move about in the Zope filesystem and add instances of my VProduct class as I want to. I have not been able to successfully integrate the file upload feature. What I have done is: * Add an input file <input type=file name=file> in the addForm method * Putting a file name in this field and pressing submit button >From here I am not quite sure what to do with the image, but from browsing earlier postings about this, it seems to have something to do with calling manage_upload one way or the other. In the VProduct_add method, I have the following special code: <dtml-call "REQUEST.set('ts', ZopeTime ())"> <dtml-call "REQUEST.set('id', _.str(_.int('ts')))"> The above code generates a unique id for my VProduct instances, and this works fine. Inside the automatically generated: <dtml-with "VProduct.createInObjectManager(REQUEST['id'], REQUEST)"> further down in the VProduct_add method I have the following stuff: <dtml-call "propertysheets.Basic.mange_editProperties (REQUEST)"> that code should take care of modifying the properties of my VProduct instance (and assumes I guess that the input field names match the property names). This seams to work great. Right before the "propertysheets..." line I have tried adding the following: <dtml-call "manage_upload(REQUEST['file'])"> It does not generate an error. But it does not seem to manage the upload part either, since my VProduct instance gets the content_type "text/plain" (instead of image/jpeg which is the right type for the jpeg file I try to upload). And when I try to "view" the VProduct instance, I get a simple <img src="91231912" alt="sometext"> tag which displays like a missing image in a web browser (no wonder since the content_type is wrong). I have tried manually setting the content_type to "image/jpeg", but the image still does not display correctly. My guess is that the image never got uploaded. Any ideas on how to handle the upload properly? I've done some 30 searches through the list archive, without any clear answers to how the image uploads are handled (or should be handled). I've looked carefully through the howto's but have not found anything. Any help would be appreciated. Marius Kjeldahl
