我该怎么做才能显示ForeignKey protected_area的名字字段?:
class NotificationReceiverSerializer(serializers.ModelSerializer):
class Meta:
model = NotificationReceiver
fields = ('pk','cellphone', 'protected_area__name')
所以现在它正如预期的那样显示为PK:
protected_area":1
答案 0 :(得分:2)
尝试这样的事情。
class NotificationReceiverSerializer(serializers.ModelSerializer):
proteced_area = serializers.ReadOnlyField(source="protected_area.name")
class Meta:
model = NotificationReceiver
fields = ('pk','cellphone', 'protected_area')
这会将protected_area名称显示为只读字段。或者,
class NotificationReceiverSerializer(serializers.ModelSerializer):
proteced_area = ProtectedAreaSerializer(read_only=True, many=True)
class Meta:
model = NotificationReceiver
fields = ('pk','cellphone', 'protected_area')
显示相关模型中的所有字段
