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><br> > 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

Need to programmatically change image content
by John Schinnerer 03 Sep '04

03 Sep '04

Hello, I need to programmatically replace the 'content' (e.g. the image file data, if I grok correctly) of an Image object with new data via file upload from web form. I imagine I could just delete the existing object and then add the new one... Is that the best/easiest way, or is there some slick way to replace the image file data for a given Image object? thanks, John S. __________________________________ Do you Yahoo!? Yahoo!

Active Zope threads and connection cache size
by Dennis Allison 25 Jun '04

25 Jun '04

Does the size of the connection cache need to grow when Zope runs more threads. I currently am running 8 threads (default 4). I note that the current OODB connection cache size is FIXED at 7. Do I need to increase the size? I would have guessed the connection cache should be somewhat larger than the number of threads and that it should be set dynamically. Can anyone hazard a guess as to what it should be? twice the number of threads? more? I am running Zope 2.6.3b2 but I think the same question is relevant for all versions of Zope.

In earlier ZODB versions (that distributed with Zope 2.6.x), "clear" caused a SIGSEGV. Then, I used "minimize" instead of "clear". The current ZODB version (that distributed with Zope 2.7) does not have problems with "cache.clear()". We use it without problems. -- Dieter

Using Access Rules
by Dennis Allison 01 May '04

01 May '04

I want to add some special checking to prevent direct, through the web access to authenticated users who, I discover, can get a second browser window and move around the site from URL independent of access path. Suppose I have pages stored in a folder structure rooted at /foo. The view security permission on /foo/... requires an Authenticated User. Normally pages are served from /foo/... under programatic control and additional constraints are applied. But, if the user creates another browser window and if he/she knows the URL (or the root URL) they can move about /foo/... however they want by simply entering the URL into the browser. (This works because they are authenticated and the authentication is shared in the browser.) An access rule seems to be the right mechanism for this sort of test, but I don't quite understand how to manage the control flow. I put the access rule in /foo. It gets executed when /foo is traversed. Now, it appears that the access rules are executed for side-effects only. If that's the case, the way an error message is returned to the caller is by modifying REQUEST to reference the error message object and not the object originally specified. Returning without changing the REQUEST allows Zope to continue traversing the path. Is my model correct?
