概述
{
"created_by": [
"This field is required."
]
}我想这是因为unique_together索引.
models.py：
class UserVote(models.Model): created_by = models.ForeignKey(User,related_name='userVotes') rating = models.ForeignKey(rating) class Meta: unique_together = ('created_by','rating')
serializers.py
class UserVoteSerializer(serializers.ModelSerializer): id = serializers.IntegerField(read_only=True) created_by = UserSerializer(read_only=True) class Meta: model = UserVote fields = ('id','rating','created_by')
views.py
class UserVoteViewSet(viewsets.ModelViewSet): queryset = UserVote.objects.all() serializer_class = UserVoteSerializer permission_classes = (IsCreatedByOrReadOnly,) def perform_create(self,serializer): serializer.save(created_by=self.request.user)
如何在不让用户提供created_by的情况下将模型保存在DRF中,而是在代码中自动设置此字段？
提前致谢！
def create(self,request,*args,**kwargs): uv = UserVote(created_by=self.request.user) serializer = self.serializer_class(uv,data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data,status=status.HTTP_201_CREATED) else: return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)
总结
以上是编程之家为你收集整理的python – Django REST框架：“此字段是必需的.”with required = False和unique_together全部内容，希望文章能够帮你解决python – Django REST框架：“此字段是必需的.”with required = False和unique_together所遇到的程序开发问题。
