大家好，我想分享我最近作为个人项目开发的 discourse-graphql 插件。该插件仍在开发中，目前仅暴露了 3 个查询字段。由于我个人并不使用 Discourse API 进行集成，因此希望潜在用户能告诉我你们希望看到哪些查询或变更（mutation）被添加到插件中。请在本主题中提供您的使用场景以及您期望的字段，以便我将其添加到插件中。

你好 @tgxworld，内容非常有趣。
既然你已经在朝这个方向努力了——你觉得

怎么样？

或者，将它与 Discourse 一起使用是个疯狂的想法吗？
据我所知，它与 Rails 配合得很好，包括支持 Rails 认证（Redis、Memcache、Cookie）。它可以集成到现有的 Rails 应用中，但我不确定将其用于插件是否现实。

你怎么看？

你好 @4ong :wave:

Super Graph 看起来很有趣，但我不确定它是否适合我们的需求。我发现主要问题在于我们需要生成的 SQL 查询并不简单，可能涉及许多条件分支。这些条件可能很难仅通过 GraphQL 查询来表达。

亲爱的 Alex，

感谢您分享这个插件。通过阅读您的插件代码以及您处理这个问题的方式，我学到了很多。

已收藏！

再次感谢。

谢谢，我想这个插件将对我在 Discourse 实例中需要的某些自定义 GraphQL 端点有很大帮助。

不过，Discourse 在重建后返回了 502 Bad Gateway 错误。

以下是日志：

我不明白这代表什么。Stack Overflow 上有一个 回答 提到了类似的错误信息，但我不确定是否适用于这里。

您有什么想法吗？

编辑：我已提交了一个 PR 来修复此问题。

谢谢。

抱歉，我将关闭此话题。我尚未有时间将该插件完善到理想状态，而且 Discourse 方面实际上也没有这方面的迫切需求。
