Hi!
I'm trying to filter my data by some date calculations.
In detail, I want to filter out messages that have been marked as
"deleted" more than 30 days ago.
In a query I could do it like this:
threshold = datetime.now() - datetime.timedelta(30)
return Message.query().filter(Message.deleted > threshold).all()
But how can I do it in a relation() that returns all deleted messages?
I'd have to calculate the threshold on every call to the relation or
I'd have to create a query that will do the calculation in SQL.
For both options I don't know how I could accomplish it.
messages_deleted=relation(
Message,
primaryjoin=and_(<conditions to create the relation>,
message_table.c.deleted > ????),
),
Any ideas?
