python - 测试模型序列化器

Question

我正在尝试学习测试序列化器的最佳方法，但遇到了一些问题。在下面的示例中，我正在测试创建新用户是否正常工作。即可以对密码进行哈希处理。我收到的错误是:

TypeError: create() missing 1 required positional argument: 'validated_data'

我不太确定我需要传递什么作为 validated_data

序列化器.py

class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'password')
        extra_kwargs = {
            'url': {'view_name': 'user-detail'},
            'password': {'write_only': True}
        }

    def create(self, validated_data):
        user = User.objects.create_user(
            username=validated_data['username'],
            email=validated_data['email'])

        user.set_password(validated_data['password'])
        user.save()

        return user

    def update(self, instance, validated_data):
        user = User.objects.get(id=instance.id)
        user.set_password(validated_data['password'])
        user.save()

        return user

测试.py

class UserSerializerTest(APITestCase):
    def setUp(self):

        factory = APIRequestFactory()

        request = factory.get(path=reverse('user-list'))

        self.serializer_context = {
            'request': Request(request),
        }

    def test_create_user(self):
        from .serializers import UserSerializer

        data = {'username': 'temp_usr', 'email': 'temp@email.com',
                'password': 'temp_pass'}

        user = UserSerializer(data=data, context=self.serializer_context).create()

您在测试中调用了create。您应该调用 is_valid，然后保存。

user = UserSerializer(data=data, context=self.serializer_context)
user.is_valid(raise_exception=True)
user.save()
