Resize a image stored in a Oracle's BLOB Field
by Juan Javier Carrera Obrero 27 Nov '01

27 Nov '01

Hello, Thanks, I have displayed the images which them was stored in a Oracle's BLOB field, with: <dtml-call expr="RESPONSE.setHeader('content-type','image/jpeg')"> <dtml-in SQLMethod_with_a_Only_Row> <dtml-var expr="BLOB_FIELD.read()"> </dtml-in> However, I would like to resize this image. I can not do it with the "height" and "width" attributes, because the image is obtained from a Oracle's BLOB field, and no from image object (i.e.: I can not use <dtml-var "ImageObject.tag(border='5', align='left')">). How can I do it ? Thanks again !

manage_workspace => index_html
by The Doctor What 08 Jul '01

08 Jul '01

My workspace keeps being redirected to index_html.... Example: http://host/manage_workspace redirects me to http://host/ Likewise, http://host/pi/manage_workspace redirects me to http://host/pi/ I don't understand it, but I see that netscape navigator doesn't seem to have this problem. But Mozilla and Lynx does! Here is some output from lynx: lynx -head -source -nopause -auth=id:pass http://linuxasm.gerf.org:9673/manage_workspace HTTP/1.0 302 Moved Temporarily Server: Zope/Zope 2.3.2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Mon, 14 May 2001 20:28:12 GMT Bobo-Exception-File: /usr/lib/zope/lib/python/App/Management.py Bobo-Exception-Type: Redirect Location: http://linuxasm.gerf.org:9673/index_html Bobo-Exception-Value: http://linuxasm.gerf.org:9673/index_html Content-Length: 0 Bobo-Exception-Line: 152 X-Cache: MISS from lego.gerf.net X-Cache-Lookup: MISS from lego.gerf.net:3128 Proxy-Connection: close What's going on?

Wildcards in TextIndex query. Do they work?
by Erik Enge 24 Jun '01

24 Jun '01

Hi, is it me, or is this just not working: (word1 or word*) and (wor?3) ie. wildcards in TextIndex queries. I can't seem to make it work, and I'm not able to track down where it stops working. Should it work in the first place? Zope 2.3.2 Thanks.

ZCatalog phrase indexing revisited
by Oren Yosifon 20 Jun '01

20 Jun '01

Hi all, I'm asking this again ,in case anything has changed since the last time. I'm trying to search for a phrase in ZCatalog, but, it doesn't seem to work. Let's say I want to search for "foo bar", if i ask ZCatalog to find it, it treats it as if I wrote "foo OR bar" . Last time I asked this, SteveA kindly replied: You should use quotes to group the phrase. ['"foo bar"'] Take a look in the source code: lib/python/SearchIndex/UnTextIndex.py Follow the flow of code through from line 550: def query( ... however, this doesn't seem to work. You can try it even on the zope.org website using their search interface. Using the above suggested syntax (incl. the brackets) returns an error message. Can anyone help me ? Thx. oren.

Bulletproof ZCatalog proposal
by Shane Hathaway 07 Jun '01

07 Jun '01

I have written a proposal. http://dev.zope.org/Wikis/DevSite/Proposals/ArmoredCatalog Could it be that we're involved in yet another Battle of Fredericksburg and we're trying to save innocent ZCatalogs from a ZODB conflict? Nawww... ;-) Shane

Very strange! Even if the exception was captured, this should not cause Zope to die. Did you look in the log files? Have their been any core dumps? Dieter

dtml-in batching improved
by Ivo van der Wijk 03 Jun '01

03 Jun '01

Hi all, When using batching in dtml-in, why is 'previous-sequence' only defined at the first iteration of the current batch? And why is 'next-sequence' only defined at the last iteration of the current batch? This behaviour makes it difficult to display a batch like this: -- begin sample -- Item N Item N+1 Item N+2 (link to previous items) (link to next items) -- end sample -- Because the code would be something like: -- begin sample -- <dtml-in something start=query_start size=3> [do something with sequence-item] <dtml-if sequence-end>  <dtml-if previous-sequence> (link to previous items) </dtml-if> <dtml-if next-sequence> (link to next items) </dtml-if> </dtml-if> </dtml-in> -- end sample -- However, if your batchsize is larger than 1, 'previous-sequence' will always be untrue at the last item (when sequence-item is true). The only solution would be implement a second dtml-in after the first one purely for displaying the previous link. Also, dtml-in would re-execute your "expr" (which it does not very efficiently), so if you want to avoid doing the "expr" twice, you'd have to store it temporarily using dtml-let (or my dtml-set tag ;). The end result would be: -- start sample -- <dtml-let foo="expr"> <dtml-in foo start=start_query size=3> [do something with sequence-item] </dtml-in> <dtml-in foo start=start_query size=3>  <dtml-if sequence-end> <dtml-if previous-sequence> (link to previous items) </dtml-if> <dtml-if next-sequence> (link to next items) </dtml-if> </dtml-if> </dtml-in> </dtml-let> -- end sample -- And at this point I really would start to implement the batching myself in python :) Of course, basically the same applies if you want both the previous/next link at the top of the batch display. (Imagine you want both! :) Either I'm missing something really obvious here, or the patches below make sense. There are two versions: - patch #1: This version fixes the issue above by enabling the values of previous/next-sequence throughout the entire batch (and other related variables as well: X-sequence, X-sequence-start-index, X-sequence-end-index, X-sequence-size) (which may break existing sites), and - patch #2: This version introduces new variablenames, leaving the behaviour of previous/next-sequence. A third alternative would be to only define the variables at the top and bottom of the batch. Both versions fix (I think) a grammatical error. It's up to the DC guys if they feel like incorporating either of these patches in a next release :) patch #1: define variables everywhere in the batch This patch makes sure that the following variables are available through each iteration of dtml-in, for each item. !!!!!

Does creating REAL over-the-web Python code become realistic with Zope 2.4?
by Joachim Werner 02 Jun '01

02 Jun '01

Hi! When I read about the reload functionality of Zope 2.4, an old vision came back to my mind: If we can reload Python code at runtime, and we can also edit, generate and store files (containing code) via the web (as LocalFS or extFile prove), then it should be perfectly possible to have something like ZClasses (it terms of the over-the-web front-end) that spits out and dynamically loads REAL Python classes instead of the rather experimental simulation of classes we get with ZClasses, right? I'll skip the part about why we should not be able to manipulate Zope code over the web, which can be discussed separately ... What do you think about this idea? If it finds some friends, I'll set up a formal proposal for something like "ZClass-like features to build REAL Zope Python classes over the web". Joachim
