如何在django rest框架中为枚举字段创建序列化程序

我正在用python django rest框架编写一个API，我一直在为枚举创建序列化器字段，如何为枚举字段创建序列化器字段。 我的型号代码是：

class Queue(models.Model):
    class Meta:
        db_table = 'queues'

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True)
    name = models.CharField(max_length=45)
    type = EnumChoiceField(QueueTypes, default=QueueTypes.pending)
    date = models.DateTimeField(auto_now=True)

我正在为这个模型编写一个序列化程序

class QueueSerializer(serializers.ModelSerializer):
    class Meta:
        model = Queue
        fields = ('__all__')

    id = serializers.CharField(read_only=True)
    name = serializers.CharField(max_length=45, required=True)
    type=?????# what am i supposed to do here?
    date = serializers.DateTimeField(read_only=True)

在谷歌上做了大量搜索之后，我终于找到了EnumchoiceField序列化问题的答案。以下更改完成了这项工作

myModel.py：

from enumchoicefield import ChoiceEnum, EnumChoiceField

class QueueTypes(ChoiceEnum):
    appointment = "appointment"
    wait = "wait"
    process = "process"
    pending = "pending"

class Queue(models.Model):
    class Meta:
       db_table = 'queues'

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True)
    name = models.CharField(max_length=45)
    type = EnumChoiceField(enum_class=QueueTypes , default=QueueTypes.process)
    date = models.DateTimeField(auto_now=True)
    fk_department = models.ForeignKey(Department, related_name='department',null=True, on_delete=models.CASCADE)

from enumchoicefield import ChoiceEnum, EnumChoiceField

class QueueSerializer(serializers.ModelSerializer):
    class Meta:
        model = Queue
        fields = ('__all__')

    id = serializers.UUIDField(read_only=True)
    name = serializers.CharField(max_length=45, required=True)
    type = EnumChoiceField(enum_class=QueueTypes)
    date = serializers.DateTimeField(read_only=True)

mySerialize.py：

from enumchoicefield import ChoiceEnum, EnumChoiceField

class QueueTypes(ChoiceEnum):
    appointment = "appointment"
    wait = "wait"
    process = "process"
    pending = "pending"

class Queue(models.Model):
    class Meta:
       db_table = 'queues'

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True)
    name = models.CharField(max_length=45)
    type = EnumChoiceField(enum_class=QueueTypes , default=QueueTypes.process)
    date = models.DateTimeField(auto_now=True)
    fk_department = models.ForeignKey(Department, related_name='department',null=True, on_delete=models.CASCADE)

from enumchoicefield import ChoiceEnum, EnumChoiceField

class QueueSerializer(serializers.ModelSerializer):
    class Meta:
        model = Queue
        fields = ('__all__')

    id = serializers.UUIDField(read_only=True)
    name = serializers.CharField(max_length=45, required=True)
    type = EnumChoiceField(enum_class=QueueTypes)
    date = serializers.DateTimeField(read_only=True)

EnumChoiceField

扩展似乎工作正常，但不正确支持REST框架的HTML支持呈现，序列化为

EnumChoiceField

的字段不会呈现。

我可以看到EnumChoiceField是一个自定义字段。DRF还支持定义自定义字段映射，请看这里：可能有帮助。是的，这是一个自定义字段，用于django模型中ENUM的实现，谢谢我查看链接。

EnumChoiceField

不是django的一部分。它从何而来？我在model.py中创建了一个枚举。我通过在google上搜索django enum choicefield找到了一个解决方案，看看不支持DRF的

ModelViewSet

中的

filter\u字段。除此之外，似乎还可以。既然您使用的是
ModelSerializer
，为什么还要声明
type=enumcoocefield（…）
？它们不是必需的。对于只读字段，您只需要在元数据中的
read_only_fields=（'id'，'date'）
中声明它们
