Python 发送带有相关对象的JsonResponse

我想发送带有相关对象的JsonResponse。这是我的操场

我照你说的做

def get_stocks(qty=9):
  return Stock.objects.values()[:9]

# Returning stocks
stocks = api_services.get_stocks()
return JsonResponse(list(stocks), safe=False)

我的模特就像

class Sector(models.Model):
  name = models.CharField(max_length=200, null=True, blank=True)
  original_name = models.CharField(max_length=200)
  slug = models.CharField(max_length=200) 

class Industry(models.Model):
  name = models.CharField(max_length=200, null=True, blank=True)
  original_name = models.CharField(max_length=200)
  slug = models.CharField(max_length=200)   

class Stock(models.Model):
  name = models.CharField(max_length=200)
  ticker = models.CharField(max_length=200, unique=True)
  logo = models.CharField(max_length=200, null=True, blank=True)
  website = models.CharField(max_length=200, null=True, blank=True)
  sector = models.ForeignKey(Sector, on_delete=models.CASCADE, null=True)  
  industry = models.ForeignKey(Industry, on_delete=models.CASCADE, null=True)  

如何获取包含相关对象的json？现在我明白了

0   Object { id: 1, name: "Tesla", ticker: "TSLA", … }
id  1
name    "Tesla"
ticker  "TSLA"
logo    null
website "http://www.tesla.com"
sector_id   1
industry_id 1

我还需要获取部门和行业

您需要在股票模型中查找给定ID的模型条目。你可以用你的方法来做。另一种选择是使用股票。 例如：

def get_stocks(qty=9):
   stocks = Stock.objects.all()[:qty]
   for stock in stocks:
      try:
         stock.sector = Sector.objects.get(id=stock.sector)
      except Sector.DoesNotExist:
         pass
     
      try:
         stock.industry = Industry.objects.get(id=stock.industry)
      except Industry.DoesNotExist:
         pass

   return stocks
