Hi, I am trying to upgrade an old 2.10 instance to 2.13, and I appear to be having trouble with the Psycopg connection and ZSQL methods. First of all, it took some work to uncover that I had to download the source code for Psycopg in order to get the ZPsycopgDA zope product (easy_install psycopg2 didn't give it to me). Second, it took some more work to uncover that I had to separately install the ZSQLMethods product. I think it would be helpful if these facts would be mentioned at http://docs.zope.org/zope2/zope2book/RelationalDatabases.html which just says "PostgreSQL: The newest and prefered DA is ZPsycopgDA included in psycopg."
However, I've gotten past that stage, and I can create database connections and ZSQL methods which seem to work. However, the existing ZSQL methods and/or database connection in my (copied over) old Data.fs are still causing problems. Whenever I try to view a page which calls one of those methods, or even try to navigate in the ZMI to the folder *containing* them, I get the error TypeError: ('argument list must be a tuple', <class 'Shared.DC.ZRDB.DA.SQL'>, None) The only help I've been able to find online is this brief exchange: http://comments.gmane.org/gmane.comp.web.zope.general/63079 which might be helpful to me if I knew what "_p_changed = 1 or some such" meant. Can anyone help? Thanks!
