Hi all,
This is a topic that has been discussed before, but I haven't been
able to successfully implement any of the proposed solutions in my own
code. I've created a few Views in my postgres database, and I'm
looking for a way to simply query them from sqlalchemy. I tried just
treating them as tables, but this failed when the mapper wasn't able
to find a primary key (makes sense).
The code I tried was just a naive attempt:
class SpectrumView(object):
pass
spectrum_view = Table('spectrum_view', metadata, autoload=True)
mapper(SpectrumView, spectrum_view)
So I read in some message that it might be possible to specify a
primary key to the mapper, like
mapper(SpectrumView, spectrum_view, primary_key=[..]), but the problem
is I'm not defining my tables in python - they are already created, so
I don't have any column objects to pass to primary_key.
Anyway, I'm just curious to see if anyone has had success with an
implementation of database views in sqlalchemy, and possibly examples
of those cases.
Thanks,
Adrian
