November 2002 - Zope

22 Nov '02

I have pages using the dynamic kebas_data technique described in the howto accompanying this very cool product. Occasionally (maybe 2%) I am getting Key Errors for reasons I am trying to figure out. I think the error is due to the dynamic thingy being not too robust when many requests hit simultaneously. There may even be no solution. The good news is that requesting the page a second time always works. The site is in production, so until I figure out how to fix the errors I thought of using something like this: <dtml-try> <dtml-var "mykebas.view()"> <dtml-except KeyError> <dtml-call "RESPONSE.redirect(URL)"> </dtml-try> Something tells me this is asking for trouble even if the error never repeats itself. Apart from rooting out the error, what would be the correct way to handle this? Thanks!

Within the Control_Panel/Database/ Cache Parameters there is a "Target max time between accesses" what is the Unit for this value? Seconds? Minutes? I haven't found it documented anywhere. Thanks, -Brian

Thanks Dieter, Paul and P.T, Although Dieter did give me the correct explanation a few mails ago, I did not realise at that time that the Directory View folders in the portal_skins are called just that (I confused it with LocalFS folders) - thanks Paul for pointing that out and telling me exactly where to look - I'm probably at the point where I know just about enough of CMF to be dangerous! Dieter (and Chris!), once again, sorry for the HTML spew, M$ Outlook has a mind of it's own, and will either send HTML or two messages, one HTML and one Text, I am now using Outlook Express to write mails to news groups (I can't uninstall Outlook - company policy) and hope it is better behaved. Anyway, my problem is solved, so now I can go and be the hero on the "Bug in FileDirectoryView with INSTANCE_HOME on win?" thread I have just noticed ;) Thanks again Etienne

Returning a pil generated image from a python product
by Sean K 22 Nov '02

22 Nov '02

I am writing a product that returns an image generated by pil (unfortunately it doesn't): Create image- im = PIL.Image.new('RGB',(width,height)) it is then drawn- draw = ImageDraw.Draw(im) draw.rectangle([0,0,width,height], fill=(250,250,250)) etc etc etc after it is ready to be sent out I "save" it - pic = cStringIO.StringIO() im.save(pic, 'GIF') and send it pic.seek(0) RESPONSE.setHeader("Content-type", "image/gif") RESPONSE.write(pic.read()) my index_html <dtml-var standard_html_header> <IMG src="./dynamicImage?RESPONSE=RESPONSE"> <dtml-var standard_html_footer> the product class inherits Item, Persistent and Implicit the dynamicImage method has an argument RESPONSE When I click on view all I get is an image placeholder box (true as well when using the same image tag in a dtml method in the root folder), however from a dtml method in the root folder <dtml-var expr="TestObject.dynamicImage(RESPONSE)"> will render an image as the only content. any other content in the method is ignored. This is my first attempt at a product, so after much hair pulling I must get it to work. Thank you in advance for any help Sean K --------------------------------- Do you Yahoo!? Yahoo!

automatically add to ZCatalog?
by tom smith 22 Nov '02

22 Nov '02

I have a blog where a search show the latest BlogItems ordered by date I've looked everywhere and can't work out how to automatically add a BlogItemClass instance to my ZCatalog. Currently I have to go to the catalog and click "Find Objects" which is a pain I think I tried to automatically update the whole catalog (3000+ items) but this was too slow to be reasonable. Surely there is a way (in python) to add an item to the ZCatalog and index just it. cheers tom p.s myObj.re_index() doesn't seem to make any difference either -- tom smith http://www.othermedia.com/blog/ 0207 089 5959 3rd Floor, The Pavilion, Newham's Row, London SE1 3UZ
