在客户端创建UUID，并使用Django REST Framework保存主键并使用POST [英] Create UUID on client and save primary key with Django REST Framework and using a POST

问题描述

我想要在客户端上创建一个 UUID 并将其发送到Django Rest Framework （DRF），并使用对于主键的模型。

I'd like to be able to create a UUID on the client and send it to Django Rest Framework (DRF) and use that for the Primary Key of the Model.

到目前为止，当我发送主在我的源代码中标有 id 的键，DRF忽略 id 并使用模型的默认参数生成一个新的 UUID 。

So far, when I send the Primary Key, which is labeled id in my source code, DRF ignores the id and uses the default argument of the Model to generate a fresh UUID.

然而，当我从模型测试时，使用正常的Django ORM创建对象，并预先设置 UUID ，模型接受 UUID ，因为它主键，不尝试重新创建一个新的。

However, when I test from the Model, using the normal Django ORM to create the object, and pre-set the UUID, the Model accepts the UUID as it's Primary Key and doesn't try and recreate a new one.

这是可能吗？

我的堆栈是

• Django 1.8

• Django 1.8

Django Rest Framework 3.1

Django Rest Framework 3.1

这是代码。

serializers.py：

class PersonCreateSerializer(serializers.ModelSerializer):
    class Meta:
        model = Person
        fields = ('id', 'username', 'email', 'password')

models.py：

from django.contrib.auth.models import AbstractUser

class BaseModel(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)

class Person(AbstractUser, BaseModel):

推荐答案

串行器的 id 字段设置为只读，因为 editable = False 参数。

The id field of the serializer is set as read-only because of the editable=False argument.

具有editable = False设置的模型字段，AutoField字段将
默认设置为只读， p>

Model fields which have editable=False set, and AutoField fields will be set to read-only by default,

尝试明确声明：

class PersonCreateSerializer(serializers.ModelSerializer):
    # Explicit declaration sets the field to be `read_only=False`
    id = serializers.UUIDField()

    class Meta:
        model = Person
        fields = ('id', 'username', 'email', 'password')
