我的django 版本是1.9 ，问题出在了get_all_field_names()方法（此方法在1.8后已经被删除了），作者有提示让测试了，我没有注意到，但是大家还是要注意到自己版本如果大于1.8会存在问题：

    def amend_model_params(self, **kwargs):
        params = kwargs.copy()
        if 'subscribe_time' in params:
            params['subscribe_time'] = \
                datetime.fromtimestamp(params['subscribe_time'], pytz.utc)
        params['subscribe'] = bool(params['subscribe'])
        params['last_login'] = timezone.now()
        # TODO get_all_field_names is deprecated, need test case here
        field_list = WechatUser._meta.get_all_field_names()
        for field in params.keys():
            if field not in field_list:
                params.pop(field)
        return params

我是这样修改的：

def amend_model_params(self, **kwargs):
        params = kwargs.copy()
        if 'subscribe_time' in params:
            params['subscribe_time'] = \
                datetime.fromtimestamp(params['subscribe_time'], pytz.utc)
        params['subscribe'] = bool(params['subscribe'])
        params['last_login'] = timezone.now()
        # TODO get_all_field_names is deprecated, need test case here
        field_list = WechatUser._meta.fields
        fields = []
        for field in field_list:
            fields.append(field.name)

        for field in params.keys():
            if field not in fields:
                params.pop(field)
        return params

这是你本地数据库的报错吧，跟WeCron没有关系。。。
