Ah ok, sorry.  I'll give your code a closer look then.

Re: [sqlalchemy] Postgres Composite Columns

[Zac Goldstein]

Thanks for your response Mike.  I submitted an issue to the 
sqlalchemy-utils github around the time I made my SO post.  Mostly though 
I'm interested in finding a way around using 'typemap', which is what's 
used in every implementation of composite columns I can find.  e.g. the 
code you have suggested in the past uses it as 
well https://groups.google.com/d/msg/sqlalchemy/f9BPVHfdvbg/M88ruLo6lzQJ

just a note that I'm not sure there are sqlalchemy-utils people here, 
you might want to try pinging Konsta via

Hello,

I'm having some difficulty implementing postgres composite columns. 
  I've been working off of the sqlalchemy-utils implementation: 
http://sqlalchemy-utils.readthedocs.io/en/latest/_modules/sqlalchemy_utils/types/pg_composite.html. 
  I've also looked at relevant posts here, but they all break down at 
the same point.


Specifically, all the implementations I have found use 'typemap' in the 
___getattr__ function, but 'typemap' is now deprecated, and I'm having 
trouble properly resolving attribute lookups.  More details in my SO 
post: http://stackoverflow.com/questions/43727685/sqlalchemy-postgres-composite-type-column.


Thanks
