ZPsycopgDA -- psycopg2 Zope adapter

• Psycopg mailing list

This is the PostgreSQL adapter for Zope 2 and 3 based on psycopg2.

As of version 2.4.6, ZPsycopgDA has the same content of the ZPsycopgDA module included in Psycopg 2.4.6. Future psycopg2 versions will likely not include ZPsycopgDA, which should be installed separately.

Prerequisites

ZPsycopgDA depends on the psycopg2 module version at least 2.4. Don't use versions 2.4.2 or 2.4.3: they are not compatible with ZPsycopgDA. Install the latest version available.

Installation

Unfortunately I'm no Zope expert, so these installation instructions are quite approximative. Please contact us if you want to improve them.

• Make sure to have your Zope lib directory in the $PYTHONPATH. If some command fails with:

  [...]
  File "[...]/ZPsycopgDA/db.py", line 18, in <module>
    from Shared.DC.ZRDB.TM import TM
  ImportError: No module named Shared.DC.ZRDB.TM
  

  you are probably missing it.

• Download the ZPsycopgDA package, unpack it and copy the ZPsycopgDA directory into the Products directory of your Zope instance.

• Alternatively run easy_install ZPsycopgDA or pip install ZPsycopgDA, then symlink or copy the ZPsycopgDA directory from the installed location to the Products directory of your Zope instance.

• Another reason for errors like ModuleNotFoundError: No module named 'Shared.DC.ZRDB' might be missing Products.ZSQLMethods
