Question

这是我的序列化程序 -

class WidgetListSerializer(EncryptedLookupModelSerializer):

    owner = serializers.SlugRelatedField(
        slug_field='username',
        queryset=MyAppUser.objects.filter(user=self.context['request'].user),
        default = serializers.CurrentUserDefault())
    parent = serializers.SlugRelatedField(
        slug_field='name',
        queryset=WidgetList.objects.all())

    class Meta:
        model=WidgetList
        fields = ('id', 'name', 'description', 'owner', 'parent')

我得到以下追溯：

Exception Type: NameError at /api/widgetlists/
Exception Value: name 'self' is not defined

我基本上希望序列化程序只在POST HTML中返回显示当前用户的能力，而不是当前所有用户。

那是因为你不能在字段定义中使用self（与模型的字段相同）。自我没有定义。如果我理解正确，您想要返回当前用户的用户名。

class WidgetListSerializer(EncryptedLookupModelSerializer):
    owner = serializers.SerializerMethodField()
    ...

    def get_owner(self, obj):
        return self.context['request'].user.username

DRF序列化器 - 名称＆＃39; self＆＃39;没有定义
