A simple shared budget manager web application
2616bed4ff
The previous query was working fine on sqlite and mariadb, but not on
postgresql :
return self.get_bills_unordered().group_by(Bill.original_currency).count() > 1
psycopg2.errors.GroupingError: column "bill.id" must appear in the GROUP BY clause or be used in an aggregate function
The failing SQL query was:
[SQL: SELECT count(*) AS count_1
FROM (SELECT bill.id AS bill_id, ...
FROM bill JOIN person ON person.id = bill.payer_id JOIN project ON project.id = person.project_id
WHERE bill.payer_id = person.id AND person.project_id = project.id AND project.id = %(id_1)s GROUP BY bill.original_currency) AS anon_1]
The problem is that sqlalchemy creates a subquery for postgresql, and the
internal query does not make sense.
GROUP BY is not actually useful, we simply need to count the number of
distinct currencies in the list of bills.
