我有一个Report模型,该模型与Currency模型具有如下关系:
class Currency(models.Model):
name = models.CharField(max_length=48)
symbol = models.CharField(max_length=4)
code = models.CharField(max_length=3)
class Meta:
db_table = 'currency'
verbose_name = 'currency'
verbose_name_plural = 'currencies'
class Report(models.Model):
path = models.CharField(max_length=256, null=True)
currency = models.ForeignKey(Currency, on_delete=models.CASCADE)
class Meta:
db_table = 'dsr'
我想在我的views.py中获取每个报告的所有货币代码。我已经尝试过使用反向查找,但是它们似乎不适用于“全部”
我的序列化器:
class CurrencySerializer(serializers.ModelSerializer):
class Meta:
model = models.Currency
fields = '__all__'
,与报告序列化程序相同。我的views.py:
@api_view(['GET'])
def rep_currencies(request):
all_reports = models.Report.objects.all()
report_currencies = all_reports.currency_set.all()
data = serializers.CurrencySerializer(report_currencies, many=True).data
return Response(data)
返回“ QuerySet”对象的
没有属性“ currency_set”。
