Redirecting from Python?
by Christopher J. Kucera 04 Aug '00

04 Aug '00

Greetings! I'm working on a Product, and I'd like to be able to do a RESPONSE.redirect() from inside the Python code. What I had was basically this: <dtml-if "some number of conditions"> View the page . . . <dtml-else> <dtml-call "RESPONSE.redirect('blahblahblah')"> </dtml-if> This works fine, but rather than having that sitting out in DTML-land, I figured I could put the conditions in the Python code and simplify the if statement, so all I'd have to do is: <dtml-if someConditions> View the page . . . </dtml-if> The Python code I was hoping would accomplish this was: def someConditions(self): if (some number of conditions): return 1 else: self.REQUEST.RESPONSE.redirect('blahblahblah') My problem is that the redirect just doesn't happen. I've had this function return values and the like, so I know it's parsing my conditions correctly, and I can even do a "return self.REQUEST.RESPONSE.redirect" and have the function returned back into my page, but it won't actually redirect. Any ideas? Thanks in advance . . . -CJ

Zope in single thread mode during DTML rendering
by Dieter Maurer 04 Aug '00

04 Aug '00

A collegue of mine succeeded today to implement an infinite DTML loop. That happens ... However, during this loop, Zope did not respond to any request. Effectively, it was in single thread mode. Zope 2.1.6 Binary Distribution for Sparc Solaris 2.6 ZOracle DA, DCOracle, Oracle 8.1.6 After several minutes, Zope reported an "infinite recursion in document template" and the world awoke from its sleep. I was unable to reproduce this at home, though: Zope 2.1.6 Source Distribution on Linux 2 No database connections. Hugh, I have been lying: I just removed the "-D" from the Linux start script, and Zope blocked during the infinite loop. The behaviour is not related to the "-D" set or unset. It just blocks sometimes and at other times, it does not. Dieter

Confusing "sqlvar" error message
by Dieter Maurer 04 Aug '00

04 Aug '00

Today, I analysed a confusing error message from "dtml-sqlvar". SQL query template: .... <dtml-sqlvar "_[name]" type=string> .... reported: "missing input variable: _[name]" Of cause, I did not expect that such an input variable should be necessary and I suspected the DTML parser not to see the "..." around "_[name]". After analysis, the explanation was simple: SQLVar.render is a bit stupid in its error handling: try: expr=self.expr if type(expr) is type(''): v=md[expr] else: v=expr(md) except: if args.has_key('optional') and args['optional']: return 'null' raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name This error handling is only senseful for "type(expr) == type('')", i.e. for plain variable access. For true expressions, the original exception would be *much* more useful. In my case, unwrapping the "try ... except ..." produced "KeyError: FOLLUP_UP", an obvious type (FOLLOW_UP rather than FOLLUP_UP). Thus, the above exception handling should become: except: if args.has_key('optional') and args['optional']: return 'null' if type(self.expr) != type(''): raise raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name I will put it into the collector.

updating 2 catalogs
by Richard Bartels 04 Aug '00

04 Aug '00

I have created a catalogaware zclass following the instructions in How-To: Creating a CatalogAware ZClass. It works fine. Except for this: I have a catalog in root folder which indexes the whole site. Then I have catalogs in each of 6 main subfolders beneath the root folder for searching only in these folders. I am able to update both catalogs, however, when deleting the object it only is deleted from one of the catalogs, namely, the one that was updated last. Is it valid to update two catalogs in this way? Or should I be going about this another way entirely?

Almost surely, the "in" tag does not call a callable object (because it does not expect, they could be callable). You, therefore, get the method itself. It is identical for all records. Dieter

Solution Suggestions?
by Craig 04 Aug '00

04 Aug '00

Unfortunately I do not know enough about Zope yet to know what the best approach is to solving my problem, so please let me know if you have any suggestions or have done something similar before. I am trying to build a "tips" site and am trying to decide on how to store the tips. The options I can think of are database, XML documents (stored within Zope), or my own custom Zope object type or product. I've read a little about XML documents in Zope, but I know nothing about creating my own object types or products. Can anyone give me some advantages (and disadvantages) of the latter approach? Perhaps there is already a product for something similar. Squishdot is slight overkill for what I'm looking for, although I would eventually like to attach discussion threads to each tip, so maybe it is not. This is the information that would need to be stored for each tip (hypothetically) : Tip title Abstract Tip text Author (email, etc...) Date submitted Date approved (if we allow users to submit tips) Number of hits (so we can have a "10 most popular", etc...) Image link ...and more may be added as time goes on. Any thoughts?
