我有一个模型WeddingInvite,它有一个拒绝和接受邀请的方法,如下所示:
class WeddingInvite(models.Model):
from_user=models.ForeignKey(User,related_name="person_inviting")
to_user=models.ForeignKey(User,related_name="person_invited")
wedding=models.ForeignKey(Wedding,related_name="wedding_invite")
status=models.IntegerField(choices=CHOICES)
def accept(self):
attending=Attending(attendant=to_user,wedding=Wedding)
attendant.save()
self.status=1
self.save()
notification.send([self.to_user],"invite_accepted",{"invitation":self})
def decline(self):
self.status=2
self.save()
如何将方法公开给视图或序列化程序,以便人们可以接受或拒绝 通过django-rest-framework使它可以作为json传递? 以下是序列化程序和视图:
class WeddingInviteList(generics.ListCreateAPIView):
serializer_class=WeddingInviteSerializer
def list(self,request,*args,**kwargs):
wedding_invites=[]
invited=request.user
qs=WeddingInvite.objects.filter(Q(to_user=invited))
for invite in qs:
wedding_invites.append({invite.from_user,"invited you to a wedding ",invite.wedding})
return Response(wedding_invites)
class WeddingInviteSerializer(serializers.ModelSerializer):
class Meta:
model=WeddingInvite
如何在视图或序列化程序中启用接受和拒绝方法?
编辑:我意识到有一个序列化方法字段,但它返回一个值。我不知道这是否可以使用,因为我的方法与此示例不同serializer method field
关于这个或任何其他方式的正确方向的一点非常有帮助。

下面未经测试的代码,这是我可以采取的方法。
对于序列化程序:
class WeddingInviteResponseSerializer(serializers.Serializer):
response = serializers.BooleanField(required=True)
对于您的视图,请随意添加更多验证方法和用户检查。
from django.http import Http404
from rest_framework.views import APIView
from .models import WeddingInvite
from .serializers import WeddingInviteResponseSerializer
class WeddingInviteResponseView(APIView):
serializer_class = WeddingInviteResponseSerializer
def get_object(self, pk):
try:
return WeddingInvite.objects.get(pk=pk)
except WeddingInvite.DoesNotExist():
raise Http404
def post(self, request, pk):
serializer = self.serializer_class(data=request.DATA)
if serializer.is_valid():
response = serializer.data['response']
invite = self.get_object(pk)
if response.accept:
invite.accept()
return Response({'success': "Wedding Invited accepted"}) status=status.HTTP_200_OK)
else:
invite.decline()
return Response({'success': "Wedding Invited declined"}) status=status.HTTP_200_OK)
else:
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
最后,只需在您的网址中公开以下结束点:
url(r'^invite/(?P<pk>\d+)/response$', WeddingInviteResponseView.as_view(), name='wedding-invite-response')
希望这有助于指出正确的方向。
