该代码段在逻辑上是正确的，但在某些地方存在一些细节需要注意：
- 将注释中的英文“models.CharField()”替换成中文形式，“char_field_name”。这主要是为了确保翻译和执行时保持一致。
修改后的版本如下所示：
- 在设置查询集对象之前添加模型信息。

这样，我们可以避免不必要的代码重复，并使整体结构更清晰。如果您需要进一步的帮助，请随时告诉我！

在提供的代码中，没有发现明显的不规范和潜在问题，但在实现list方法逻辑时可以稍微调整一下：当with_valid=True时查询set将默认排序为ID降序。如果需要按创建时间升序排列且无条件是否启用，则可以修改get_query_set返回语句。
例如：
- 修改 get_query_set 方法：
query_set = query_set.filter(is_active=self.data.get('is_active'), status='status') query_set = query_set.order_by('-create_time')
这样就可以得到满足特定条件（仅显示已激活并且指定的状态）并按照创建日期排序的list了。
对于现有的列表操作而言，这种更改几乎不会带来任何性能变化或影响程序执行效率。
