Django-Tastypie:“；错误消息：&引用'；布尔'；对象没有属性'；阅读'&引用；

我正在使用Backbone.js+Tastypie+Django并尝试使用patch=true保存模型以更新模型上的点，如

this.save({
  points: newPoints
}, {
  patch: true
});

这将发出一个PUT请求，因为它应该与请求负载一起发出

points: 105

但是，我收到一条500错误消息

这是我的UserProfile模型资源

class UserProfileResource(ModelResource):

    """A resource for the UserProfile model."""

    class Meta:
        queryset = UserProfile.objects.all()
        resource_name = 'userprofile'
        authorization = Authorization()
        excludes = ['field_to_exclude']
        always_return_data = True

有人知道如何调试这个错误吗？

我有一个datetime字段，它是空的，在api调用中没有显示为datetime，而是显示为布尔值。我不确定为什么会发生这种情况，但我认为这是tastypie中的一个错误，或者我误解了有关配置的某些内容，或者两者兼而有之

---

我从tastypie资源中排除了此字段，并成功地将其放入模型并进行修补。

这是服务器端故障。您能在处理请求的服务器上显示一些代码吗？我已经添加了我的服务器代码——我使用的是tastypie，所以我唯一的定制就是定义资源。因为它使用的是库而不是我的代码，所以我不太确定如何跟踪它
