UUID在rest-framework中显示为整数
UUID在rest-framework中显示为整数
提问于 2021-03-12 13:24:38
这是我的model，serializer和'admin`‘
class UserData(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
pub_date = models.DateTimeField('date published',default=timezone.now)
class UserDataSerializer(serializers.ModelSerializer):
class Meta:
model = Genre
fields = ('id','pub_date')
def create(self, validated_data):
user_data = UserData()
user_data.save()
return user_data
class UserDataAdmin(admin.ModelAdmin):
list_display = ["id","pub_date"]
search_fields = ['id']在管理屏幕中，id字段如下所示
但在rest-framework中，id显示为整数。
我该怎么解决这个问题？？
感谢您的@periwinkle评论
我变了
class UserDataSerializer(serializers.ModelSerializer):
id = serializers.UUIDField(format='hex_verbose') // add this
class Meta:
model = Genre
fields = ('id','pub_date')
def create(self, validated_data):
user_data = UserData()
user_data.save()
return user_data在此之后，当POST url创建新的数据。
它显示错误
HTTP 400 Bad Request
Allow: GET, POST, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
{
"id": [
"This field is required."
]
}但是id有缺省值，所以有问题。

似乎您可以在模型中显式指定uuid格式。这是来自drf docs关于UUID的内容：
Signature: UUIDField(format='hex_verbose')
format: Determines the representation format of the uuid value
'hex_verbose' - The canonical hex representation, including hyphens: "5ce0e9a5-5ffa-654b-cee0-1238041fb31a"
'hex' - The compact hex representation of the UUID, not including hyphens: "5ce0e9a55ffa654bcee01238041fb31a"
'int' - A 128 bit integer representation of the UUID: "123456789012312313134124512351145145114"
'urn' - RFC 4122 URN representation of the UUID: "urn:uuid:5ce0e9a5-5ffa-654b-cee0-1238041fb31a" Changing the format parameters only affects representation values. All formats are accepted by to_internal_value页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
