我有型號：Django的序列化不能解析外鍵對象
class employees(models.Model):
emp_id=models.PositiveIntegerField()
emp_name = models.CharField(max_length = 100)
manager_id=models.ForeignKey('self',null=True,blank=True)
class leave(models.Model):
employee = models.ForeignKey(employees, on_delete=models.CASCADE, default='1')
start_date = models.DateField()
end_date = models.DateField()
class notify(models.Model):
sender_id=models.ForeignKey(leave, related_name='%(class)s_sendername')
receiver_id=models.ForeignKey(leave,related_name='%(class)s_receivername')
viewed=models.CharField(max_length=2)
在我的意見，我寫的查詢爲：
def notification(request):
template = loader.get_template('base.html')
user = employees.objects.get(emp_id=request.user.username)
emp_id=user.emp_id;
notification=notify.objects.filter(receiver_id__employee__emp_id=emp_id);
data = serializers.serialize("json", notification)
print(data);
context={'notification':data,'notification_count':notification_count}
femp = json.dumps(context)
return JsonResponse(femp, safe=False, content_type="text/html")
在打印（數據）的打印
[{"model": "apply.notify", "pk": 32,
"fields": {"sender_id": 121, "receiver_id": 44, "viewed": "N"}}]
這裏它的打印sender_id = 121這是離開表中的id，但如果我想start_date和emp_name（因爲它是從員工引用的假表）。我應該在serializers.serialize（）中寫什麼，以便我可以引用外鍵入門。
