如何在django-rest框架中将参数传递给序列化程序?

嗨,你可以覆盖 初始化 方法,从中弹出值并赋给变量。

class DataSerializer(serializers.Serializer):
   skip_place = True
   name = serializers.CharField(max_length=None)
   place = serializers.CharField(max_length=None,required=False)

   def __init__(self, *args, **kwargs):
       self.skip_place = kwargs.pop('skip_place ', False)
       super().__init__(*args, **kwargs)

   def validate_place(self,value):
     if not self.skip_place and len(value)<=0:
        raise serializers.ValidationError("Place is required.")

你可以把它和 including extra context .

视而不见;

DataSerializer(data=data, context={'skip_place': True}) # or False

在串行器中;

class DataSerializer(serializers.Serializer):
    name = serializers.CharField(max_length=None)
    place = serializers.CharField(max_length=None,required=False)

    def validate_place(self,value):
        skip_place = self.context.get("skip_place") # <- here we use self.context to get extra args
        if not skip_place and len(value)<=0:
            raise serializers.ValidationError("Place is required.")
