I use the SQLAlchemy ORM in my application, and I know I can use something
the following to perform an `INSERT...ON CONFLICT` statement:
from sqlalchemy.dialects.postgresql import insert
class Foo(Base):
...
bar = Column(Integer)
foo = Foo(bar=1)
insert_stmt = insert(Foo).values(bar=foo.bar)
do_update_stmt = insert_stmt.on_conflict_do_update(
set_=dict(
bar=insert_stmt.excluded.bar,
)
)
session.execute(do_update_stmt)
Is there a better solution that doesn't require dropping into the
Expression Language? It'd be great if we had a solution that automatically
detected the fields that need to be inserted / update, and that
automatically refreshed the `foo` instance after the committing to the db.
