Question

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，例如

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

这会向请求有效负载发出PUT请求

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

有没有人有关于如何调试此错误的提示？

Answer 1

我有一个字段是datetimefield，它是null，而不是在api调用中显示为日期时间，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，或者我误解了配置，或者两者兼而有之。

我从tastypie资源中排除了这个字段，我能够成功地将PUT和PATCH传递给模型。

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