Answer 1

很简单，

        $now = Carbon::now();
        $lastThreeMonth = $now->copy()->subDay(30 + 30 + 30); // 3 months

        $query = Model::whereHas('relation', function (Builder $q) use ($lastThreeMonth, $now) {
            $q->whereBetween('created_at', [$lastThreeMonth, $now]);
        });

        $result = $query->get();
