初步解决 'AutoField' object has no attribute 'rel' 问题

[Deali-Axy]

修改了 Serializer 文件的data_inspect函数。
代码如下，加了一个rel属性判断。
由于代码没有注释，一时之间也找不到具体问题在哪，所以胡乱改了一下，希望作者看到问题后进行修复。

    def data_inspect(self, data, extra=None):
        if isinstance(data, (QuerySet, Page, list)):
            convert_data = []
            if extra:
                for i, obj in enumerate(data):
                    convert_data.append(self.data_inspect(obj, extra.get(
                        **{self.through_fields[0]: obj, self.through_fields[1]: self.source_field})))
            else:
                for obj in data:
                    convert_data.append(self.data_inspect(obj))
            return convert_data
        elif isinstance(data, models.Model):

            for field in concrete_model._meta.local_fields:
                # 检查 field 是否存在 rel 这个属性，为'AutoField' object has no attribute 'rel'错误填坑
                if hasattr(field, 'rel'):
