Total of 182 bytes read in 0.126 seconds It seems there is some sort of protocol problem (miscalculation of response length perhaps?). Is this a known bug in 2.5.1? If so, is there a patch available to fix it (I'm not in a position to upgrade Zope). I tried searching the Zope Collector but saw nothing obvious in about five minutes of searching.

-1 != -1 ?
by Steffen Hausmann 17 Nov '02

17 Nov '02

Hi, I'm a bit confused. I have a Website with a select field. You can choose numbers between 7 an -7 (<option value="-7">). If the number is positive everything is fine, but if it is negative Zope behaves strange. First I convert the string "-7" into an integer publishRange = int(publishRange) and then want to know whether it is positive or negative, but if publishRange < 0: doesn't react to it (if publishRange > 0: does, if publishRange is positive). What am I doing wrong. MfG Steffen -- Manche Maenner bemuehen sich ein ganzes Leben lang, das Wesen einer Frau zu verstehen. Andere befassen sich mit weniger schwierigen Dingen, z.B. der Relativitaetstheorie.

Zope/DB2/SQLRelay and BLOBs
by Christoph Schmitz 17 Nov '02

17 Nov '02

Hi all, we're (quite happily) running Zope and DB2 (via SQLRelay) on several Linux boxes. Currently, we are trying to put large chunks of data into DB2 BLOBs and serve them via Zope. Someone suggested just using a ZSQLMethod for selecting the respective field and <dtml-var> to display it, making sure the Content-Type is correct. I tried to reproduce that solution, using an ZSQLMethod and DTML as follows: SQL Method testselect: select data from blobtest where id = 42 DTML: <dtml-in testselect> <dtml-var data> </dtml-in> All I see is a textual representation of my data in hexadecimal. A common recommendation I saw (relating to Oracle, MySQL or PostgreSQL) was to treat this issue in Python scripts. Has anyone accomplished any way of serving BLOBs from Zope in a simple fashion as shown above (or in any way at all) using DB2 and SQLRelay? I'd really like to avoid hacking database specific Python scripts... Thanks in advance, Christoph

Adding " Mail this page to a friend" to a zope site
by Jan Smith 17 Nov '02

17 Nov '02

Hi, I want to add a "Mail this page to a friend" script to a website I'm building in Zope. I've been searching for information and discovered it may be possible using Formulator or MailHost than I found something called MIME in a zope book and became confused. I didn't quite find the answer I was looking for. I am guessing that others before me have added a "mail this page to a friend" script to a zope site. How did you do it? regards Jan

Size of a zope export
by Dylan Jay 17 Nov '02

17 Nov '02

I experiencing some unexpected behaviour when performing an export. I'm trying to minimize the size of the export by removing a lot of data that isn't needed. I delete a few thousand objects and call manage_catalogClear(). However, since I still want to keep this data I put all this code in a python script and raise an exception directly after performing the export. This roles back the transaction so all the data is still retained. The problem is that the zexp file is the same size as if I hadn't deleted anything! Anyone know why this would be or another way to export a subsection of objects rather than the whole lot?

Re: Trouble with dtml-with
by Roger Fisher 16 Nov '02

16 Nov '02

Oy... the mailer collapsed the helpful TABS in the original post, which showed the folder hierarchy. Thanks to all the helpful replies I had for my need for a "dynamic" <dtml-with>. "_.getitem(StringOfObject)" works beautifully. I have a similar additional newbie problem: FolderA ...FolderB ...FolderC ......FolderD ......Method1 Method1 (in FolderC) has no problem, of course, doing a <dtml-with FolderD> I cannot figure out how to <dtml-with> to get from Method1 (in FolderC) to code in FolderB. FolderB is parallel to Method1's parent (FolderC). Thanks for any help.

REQUEST.resolve_url
by Matt 16 Nov '02

16 Nov '02

I have found remarks that this is depreciated http://www.zopelabs.com/cookbook/992809915 Is there a replacement, because restrictedTraverse is not going to help when you are using virtual hosting and someone gives you a virtual hosted URL. E.g. http://IPADDRESS/one/two/three/one/two http://virtualdomain/one/two virtualdomain maps to /one/two/three/ using restrictedTraverse on '/one/two' when given the url with the virtualdomain would not give you the correct container. regards Matt
