Hey Simon,
I am indeed getting back duplicates of aggregate ids. I reworked my query
to using exists like you suggested and now I get back correct result
count. Thanks so much for your suggestion and saving my day! I can now
move ahead on my work ticket.
Many, many, thanks again,
This is the same problem: you're writing a query that joins 3 tables
together, and then applying a "LIMIT 20" to that query. If you look
carefully at your 20 rows of psql output, I expect you'll see the same
aggregates_id appear more than once. There are less than 20 distinct
Aggregate objects.
Hey Simon,
Thanks so much for replying to my question. I reworked my code to use
sqlalchemy ORM and took off flask and paginate so I can narrow down the
issue. My models now extend from declarative_base.
engine =
create_engine('postgresql://postgres:postgres@localhost:5400/postgres')
Session
"paginate" is not an SQLAlchemy function, so you'd be better off
asking the author of whatever is providing that feature.
However, I would guess that maybe paginate is naively applying
something like "LIMIT 20" to the query. This doesn't work properly
when you join along a one-to-many
Hello, I've been struggling with this issue for the past couple of days and
would really, truly appreciate if someone could please give me pointers or
direction as to what I might be missing.
Here are my models;
class Aggregate(db.Model):
id = db.Column(UUID(as_uuid=True),
