Here is a simple request:
And I get:
PGError: ERROR: column “visits.id” must appear in the GROUP BY clause
or be used in an aggregate function
If I add visits.id to the group by clause, then it asks me to add
another column, then another, then another. Basically I have to list all
columns in the table!
What’s going wrong? From the Rails guide it seemed straightforward.
Thanks for your help
