php - 为具有18个依赖项的实体编写REST API

我正在编写REST API以将表公开给Angular前端，我遇到过这种情况：除了与主实体相对应的类（我们称之为“Ticket”）之外，我需要显示的数据位于大约10个其他表中。必须通过检查许多关联实体中的行之间建立的关系来访问其中一些数据。总的来说，我需要查询19个表，以便显示与一个Ticket行相关的完整数据集。

困难在于：我可以在这个API中编写代码来从所有这些其他表中检索数据 - 当然，没问题，就像25个方法调用一样，虽然可能有点慢，但是可以容忍。但是为了将数据返回到前端，GET响应将由一个扭曲的JSON块组成，其中包含不同级别的不同数量的成员。由于JSON的复杂性和脆弱性，这将使得利用Angular的数据变得困难。这个问题的另一端是关于Angular的POSTing和PUTing数据。修改Ticket的表单可以连接到相同的结构以最小化HTTP请求（构造一些令人厌恶的JSON，修改它的一小部分并将其余部分保持不变等），或者可以连接到单个REST端点以单独与表格接口，牺牲了大量的速度，以便在有效载荷方面获得简单性。

这个特定的应用程序（一个内部企业工具）可能永远不会有超过五个或十个用户在任何给定时刻登录，因此从服务器的角度来看，大量的流量不是一个大问题，但是做类似的事情十几个链式HTTP请求显然是一个可怕的设计决策，而另一方面，使用特殊的，基本上条件结构的JSON响应与Angular接口似乎是一个同样令人憎恶的设计决定。

有关如何纠正此问题的任何建议？我是否坚持使用其中一种选择？感谢。

编辑：数据库看起来或多或少像这样（简化版）。门票有6个FK;通过这些表和多个关联表，这些表中的每一个都存在关系。
