I'll just don't do the group and count in the database for now. I do it
like this instead:
def self.total_grouped_by_day(start_date, end_date)
visits = where(visited_at: start_date..end_date)
visits = visits.order("visited_at ASC")
visits.group_by { |v| v.visited_at.to_date }
end
And then just use visits[date].count for the counting. There will probably
not be that many records anyway...
