Django Tastypie：“error_message”：“'bool'object has no attribute'read'”

我正在使用Backbone.js + Tastypie + Django我试图用patch = true保存模型以更新点一个模型，如Django Tastypie：“error_message”：“'bool'object has no attribute'read'”

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

这发出PUT请求使用，应请求负载

points: 105

不过，我得到一个500错误信息

下面是用户配置

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

我的模型资源有没有人对如何调试这个错误提示？

这是服务器端故障。你可以在处理请求的服务器上显示一些代码吗？ – Gevious

我已经添加了我的服务器代码 - 我正在使用tastypie，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，因此我不太确定如何跟踪它 – jkeesh

我有一个字段，它是一个空的datetimefield，而不是在api调用中显示为日期时间，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，或者我误解了配置的一些内容，或者两者都有。

我从tastypie资源中排除了该字段，我能够成功地将PUT和PATCH添加到模型中。
