shoulda asked here first.
I have a use case for modelling data in a SQL schema rather than through
defining SQLAlchemy objects. However, i require a way to construct the
corresponding SQLAlchemy objects automatically from the SQL schema.
Currently i have:
from sqlalchemy import MetaData
from sqlalchemy.ext.declarative import declarative_base
meta = MetaData(bind=your_engine)
meta.reflect()
# get the table which we would like to represent as a Python object
table = meta.tables['your_table_name']
# define the object which we will use as the base class
base = declarative_base()
# create db object
MyObject =
type(str(table.fullname), (base,), {'__table__': table})
however, the relationships between objects are not created. Any ideas how
to go about doing this?
Thanks!
