Django Tastypie：“error_message”：“'bool'对象没有属性'read'”答案

【问题标题】：Django Tastypie: "error_message": "'bool' object has no attribute 'read'"Django Tastypie：“error_message”：“'bool'对象没有属性'read'”
【发布时间】：2013-07-16 09:04:31
【问题描述】：

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

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

这会发出一个 PUT 请求，因为它应该使用请求负载

points: 105

但是，我收到 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

有人有关于如何调试此错误的提示吗？

【问题讨论】：

这是服务器端故障。你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——我正在使用tastepie，所以我唯一的自定义是定义资源。由于它使用的是库而不是我的代码，我不太确定如何跟踪它

标签： django rest backbone.js tastypie

【解决方案1】：

我有一个字段，它是一个为 null 的 datetimefield，它没有在 api 调用中显示为 datetime，而是显示为一个布尔值。我不知道为什么会发生这种情况，但我认为这是 sweetpie 中的一个错误，或者我对配置有误解，或者两者兼而有之。

我从tastepie 资源中排除了这个字段，我能够成功地对模型进行PUT 和PATCH。
