使Django Rest Framework中的BooleanField为必需

Question

我有一个带有布尔值字段的模型，我想用Django rest框架反序列化，并且我希望序列化程序在发布请求中缺少字段时抱怨。但是，事实并非如此。它默默地将缺少的布尔值解释为False。

class UserProfile(models.Model):
    """
     Message between two users
"""
     user = models.OneToOneField(User, verbose_name="django authentication user", related_name='user_profile')
     newsletter = models.BooleanField(null=False)
     research = models.BooleanField(null=False)

使用以下序列化器创建模型：

 class UserProfileSerializer(serializers.ModelSerializer):
 research = BooleanField(source='research', required=True)
 newsletter = BooleanField(source='newsletter', required=True)

 class Meta:
    model = UserProfile
    fields = ('research', 'newsletter')

在我看来，我还在创建用户，因此我有一些手动步骤：

 def post(self, request, format=None):
    userprofile_serializer = UserProfileSerializer(data=request.DATA)
    reg_serializer = RegistrationSerializer(data=request.DATA)
    phone_serializer = PhoneSerializer(data=request.DATA)


    errors = {}
    if userprofile_serializer.is_valid() and reg_serializer.is_valid() and phone_serializer.is_valid():
        user = reg_serializer.save()
        data = reg_serializer.data

        user_profile = userprofile_serializer.object
        user_profile.user = user
        userprofile_serializer.save()

        return Response(data, status=status.HTTP_201_CREATED)

    errors.update(reg_serializer.errors)
    # ...
    return Response(errors, status=status.HTTP_400_BAD_REQUEST)

但是，以下测试用例失败，因为其余框架不会抱怨缺少参数，而是在from_native中插入False

     def test_error_missing_flag(self):
    data = {'username': "test", 'password': "123test", 'email': 'test@me.com',
            'newsletter': 'true', 'uuid': self.uuid}

    response = self.client.post(reverse('app_register'), data)
    # should complain that 'research' is not found
    self.assertTrue('research' in response.data)

如果我将我的“ research”字段替换为Integer字段，则序列化程序将按预期失败。有任何想法吗？

布尔字段和参数存在问题required。现在应该在 master 中修复。
