Django 基于组提供内容

Question

我有一个调查应用程序，它包含以下模型类：调查、回应、问题和答案。我想做的是根据用户所属的组限制问题。

我已经通读了 Django 模板文档（以及其他文档），但它们没有解释如何执行此操作。

我的想法是为 "type"（用户）向模型 "Question" 添加一个字段。因此，例如，Type=1 问题可能对所有人可见，而 Type=2 问题对部分用户可见（由他们添加到的组指定）。

这是正确的方法吗？是否有任何项目在做类似的事情我可以看看（我没能找到）。任何帮助，将不胜感激。提前致谢。

您不希望在只响应用户可以访问的问题的视图中编写查询。以及可以过滤掉无权访问的用户的问题详细信息权限。
