我正在尝试创建一个视图集,在该视图集中我想过滤所有具有相同参考编号的记录。成员模型中有一个参考模型字段,但它告诉我这是一个无效字段。
这是视图集:
from groups.models import Member
from ..serializers import MemberSerializer
from rest_framework import viewsets
class MemberViewSet(viewsets.ModelViewSet):
queryset = Member.objects.filter(field_name='reference')
serializer_class = MemberSerializer
这是模型:
class Member(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
group = models.ForeignKey(Group, on_delete=models.CASCADE)
reference = models.CharField(max_length=22)
balance = models.DecimalField(max_digits=12, decimal_places=2)
open_tabs = models.IntegerField()
created = models.DateTimeField(auto_now_add=True)
这是网址:
from groups.api.views.memberViews import MemberViewSet
from rest_framework.routers import DefaultRouter
router = DefaultRouter()
router.register(r'', MemberViewSet, base_name='member')
urlpatterns = router.urls
所以我想过滤掉所有具有相同参考字段值的成员对象...

如果您希望New York City; Iron Man; no superpowers
Metropolis; Superman; superpowers;
New York City; Spider-Man; superpowers;
Gotham; Batman; no superpowers;
New York City; Doctor Strange; superpowers;
在视图集中具有特定的Members
,则应覆盖reference
方法并将参数添加到url。
在视图集中:
get_queryset
和网址中:
from groups.models import Member
from ..serializers import MemberSerializer
from rest_framework import viewsets
class MemberViewSet(viewsets.ModelViewSet):
serializer_class = MemberSerializer
def get_queryset(self):
reference = self.kwargs['reference']
return Member.objects.filter(reference=reference)

引用QuerySet
您可以尝试使用以下方法将'SearchKey'
作为您要查询的参考号吗?
queryset = Member.objects.filter(reference__contains='SearchKey')
