Re: [Zope] convert python to dtml

Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

I don't understand why the uid of 1049298593 works in retrieving the record from the zcatalog, but not when used to delete the record from the zcatalog?! (I have looked at the code in Catalog.py and nothing in the uncatalog_object method provides any hints as to why this problem is occuring). Any ideas would be really appreciated! Thanks, Jonathan

Production Advice
by Jonathan Cyr 11 Oct '06

11 Oct '06

Greetings All, After a long dev cycle, I'm putting a Zope web app into production shortly... and need some advice. What is a good daily backup strategy with Zope 2.71? I'll be running ZEO, and only use three add-on products, Formulator, VarImage and PIL. My application consists of regular items in the ZODB, two python Products, and a half-dozen ZClasses Right now, I'm developing on a WinXP machine, and am considering SuSE 9.1 for my spec, any experiences, good or bad?... YAST2-installed or manually? All advice would be helpful as I weigh my options, -Jon Cyr cyrj(a)cyr.info

doc string rules
by Dennis Allison 10 Oct '06

10 Oct '06

I just had LocalFS break under Zope 2.6.4 with Python 2.3.4 due to a "missing docstring". What are the current rules? Must everything (procedures, methods, classes, modules) have docstrings? Even when running with Z_DEBUG_MODE set to "yes".

LocalFS problems with @import-ing stylesheets
by Paul Smith 11 Oct '05

11 Oct '05

Hi We've just upgraded to using LocalFS (LocalFS-1-3-andreas for the large file support) with Zope 2.7.2, and have been experiencing problems with accessing stylesheets via the @import command from within a LocalFS folder. eg: <style type="text/css" media="screen">  </style> where /site is the LocalFS folder. The problem only manifests itself using Mozilla browsers (Mozilla, Firefox, etc), and when using these browsers stylesheets are successfully requested (according to the Apache access logs) but are ignored within the page. The stylesheet validates, and works as expected if moved inline within the page, or when created as a Zope File object, rather than within LocalFS. This all worked fine on the previous versions of LocalFS we were using (1.1.0) with Zope 2.6.4. Any ideas if this is a Zope or a LocalFS thing?

Invalidating a session, creating a new
by Sune Broendum Woeller 24 Nov '04

24 Nov '04

Hi all, In the zope book, sessions chapter, is written: "Manually Invalidating A Session Data Object Developers can manually invalidate a session data object. When a session data object is invalidated, it will be flushed from the system, and will not be returned by subsequent references to REQUEST.SESSION or getSessionData(). " and : "...subsequent references to REQUEST.SESSION in this same request will return a new session data object." I would like to be able to invalidate the session object, and then create a new session with a new key, to be accessed in the next request. But I find that when invalidating a session data object, I can *still* access the old session data in subsequent references to REQUEST.SESSION, in the same request that is. I do not get a new session data object, as I should according to the zope book. And therefore I can not reference the new keys I create in the following requests. Has anyone got a solution for this problem ? It seems the invalidation goes on "between" requests. Is this an error with the sessioning machinery or in the zope book ? Below there are three test scripts, that shows what is going on. greetings, Sune B. Woeller file test1.py: ****** s = context.REQUEST.SESSION s['mykey']='myvalue' print "Page 1, add a key to session. " print "session : " print s print " " print '<a href ="test2">Page 2, invalidate session and add a new key</a> ' print '<a href ="test3">Page 3, show session</a> ' return printed ***** file test2.py: ***** s = context.REQUEST.SESSION print "Page 2, invalidate session and add a new key. " s.invalidate() s['mySecondKey']='mySecondValue' print "session after invalidate: " print s print " " print '<a href ="test1">Page 1, add a key to session</a> ' print '<a href ="test3">Page 3, show session</a> ' return printed ***** file test3.py: ***** s = context.REQUEST.SESSION print "Page 3, show session " print "session : " print s print " " print '<a href ="test1">Page 1</a> ' print '<a href ="test2">Page 2</a> ' return printed
