Zope with two platforms.
by Francisco Assis Rosa 05 Aug '00

05 Aug '00

Hi all, I have a question I would like to pose you. We want to setup a environment where we have a development platform and a staging platform (two distinct machines with two distinct Zope instances). On the development platform we want to develop Zope Products while on the staging platform we want to, based on these products, add content to our zope database. We would like to be able to have new developments on products to be passed from the development platform to the staging platform and to have new content to be passed from the staging platform to the development platform. Any ideas on how we could do that using Zope as our application server ? In particular how do you think we could deal with allowing content editing to proceed in parallel with development of products ? Is there any available solution for Zope databases integration ? Also, how would you see schema versioning How could we for instance deal with objects generated from a product if the product schema changes ? Thank you in advance, Francisco. -- Francisco Assis Rosa email: rosa(a)dynamicdiagrams.com Dynamic Diagrams tel: 401.331.2014 ext. 136 12 Basset St., Providence, RI 02903 fax: 401.331.2015

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, %s' % 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, %s' % name I will put it into the collector.
