Users using that system will create content in the ZODB. Based on feedback you begin developing version 2. Version 2 may change the schema of some objects.

During development and pre-release testing you won't have any critical data and each developer can simply recreate a new ZODB to work with. For more automated and repeatable testing your team should create some sample data and the scripts to populate a new installation with that data. If you don't do this then each time a developer or tester starts over with a clean database, then will need to expend time manually creating ad-hoc sample data to test with.

[Zope3-Users] Re: Zwiki issues with Unicode text pasted from Word
I experienced this problem too. I thought I fixed or worked around it
a while ago, though. I may have just hacked my system.
Some notes about this:
- it is the output (view) that produces the error
- add and edit work fine
- Word has nothing to do with the problem (any source of non-ascii
data will have the same effect)
- I don't remember if the problem is in zwiki or docutils
Hmm, now that I think about it, the problem might be fixed in a newer
version of docutils. I'll make a note to revisit this when I have
a few minutes. If you don't want to wait, you might search the
zope3-dev list and the Collector to see if I mentioned it there.

Ok, here are the facts that I dug up: - my installation still has the problem; I am ignoring it for now because it's not immediately critical, I don't want to replace the unicode with ascii, and the problem will be fixed later - my installation is still on Zope 3.0.0 - Zope includes docutils, which performs the actual ReST-HTML transformation Zope 3.0.0 has : # Revision: $Revision: 1.1 $ # Date: $Date: 2003/07/30 20:14:04 $ Zope 3.1.0 has : # Revision: $Revision: 3374 $ # Date: $Date: 2005-05-26 23:21:48 With this information to refresh my memory, I think I decided to look into and resolve this issue a while ago. In doing so I discovered that the new(er) zwiki+docutils in the trunk (at the time) already worked. At least, that's what I remember now. I can't find any mention of this in the zope3-dev archives. I just tried two new tests -- I used my Zope 3.1.0 installation and tried it with both the older zwiki that is in my current instance and the current version on the trunk. Both versions fail, but with different errors. The older version fails with encoding/decoding errors. Just for fun I replaced 'html = str(source)' on line 120 of zwiki/browser/wikipage.py with 'html = source'. Doing this causes the unicode character to display fine for me (using firefox on ubuntu which is set to expect UTF-8). The trunk version fails with a traversalerror. My immediate recommendation for you is 1) file a bug report in the collector 2) replace 'html = str(source)' on line 120 of zwiki/browser/wikipage.py with 'html = source' and see if that works for you.
