[sqlalchemy] Re: Defining custom types
Hi Michael, Thanks for clarifying that for me. For anyone interested, this is what I ended up with: from sqlalchemy import String sa_major_version = sqlalchemy.__version__[0:3] if sa_major_version == 0.5: from sqlalchemy.databases import postgres postgres.ischema_names['fibertype'] = String elif sa_major_version == 0.6: from sqlalchemy.dialects.postgresql import base as pg pg.ischema_names['fibertype'] = String Cheers, Demitri On 15 Oct 2009, at 16:06, Michael Bayer wrote: thatsanicehatyouh...@mac.com wrote: Hello, On 12 Oct 2009, at 21:04, Michael Bayer wrote: On Oct 12, 2009, at 4:26 PM, thatsanicehatyouh...@mac.com wrote: Hello, I have a custom type defined in my postgresql database, and this is giving me the warning: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/ site- packages/sqlalchemy/engine/base.py:1265: SAWarning: Did not recognize type 'fibertype' of column 'fiber_type' self.dialect.reflecttable(conn, table, include_columns) From an earlier email from Michael (13 September 2009), I saw that I can do something like this: sa_major_version = sqlalchemy.__version__[0:3] if sa_major_version == 0.5: from sqlalchemy.databases import postgres postgres.ischema_names['fiber_type'] = fibertype elif sa_major_version == 0.6: from sqlalchemy.dialects.postgresql import base as pg pg.ischema_names['fiber_type'] = fibertype But of course fibertype needs to be defined.
