I am trying to get the contentmirror product to work with a plone4 site. I’ve created a buildout from scratch and only included the contentmirror packages as indicated by this link:
http://code.google.com/p/contentmirror/wiki/Installation
I’ve set up the tables in a mysql database according to the instructions included in the documentation.
When I create my plone site, I get the following error:

AttributeError: adapters
So the site fails to get created. I’ve tried dropping the table, but another error pops up indicating it cannot find a table, so I think I’m in the right direction.
I’m trying to see if this is a viable means to store content to a sql database as some pages have indicated. I am definitely missing something here. Does anyone have any experience using this product to help me out?
Thanks.

Disclaimer: I have no experience using ContentMirror, so I might be totally off-target, but from what you posted it seems that the ‘id’ value is not being autoincremented for table ‘content’.
In SQLAlchemy, this is caused by an erroneous setting that overrides the default behaviour, something like
In the SQL file (‘mirror.sql’) you generated using the ‘ddl.py’ script, check that the corrisponding database schema definition for table ‘content’ has the attribute ‘AUTO_INCREMENT’ set to ‘TRUE’ for column ‘id’, as in the following example:
