如何仅将初始值设置为 Django 内联表单集中的额外字段

Question

我对Django和Python还很陌生，所以请耐心等待。我正在尝试创建一个如下所示的表格时间表。

时间表表格：

预期结果

我想要实现的是，当我调用特定的时间表时，我应该获取所有相关的时间表详细信息数据并以与工作日期/项目组合相关的所有小时数都在同一行中的方式填充上面的表格，并且相关小时数是放置在相应的工作代码下（即在图片中，第 1 行在“规范”下有 8 小时，第 2 行在 RnR 下有 12 小时）

问题

现在如何设置初始值以根据工作日/项目组合的工作代码在每一行中填充正确的小时单元格（与模型字段无关）？

其次，如果同一工作日/项目的时间是分开的（例如标准 4 小时和 Annu 4 小时），我该如何处理？我如何把它放在同一行？如果我可以使用字典来填充这会很容易吗？

由于我在 10/80/20... 字段的表单中没有任何初始数据，因此我无法检查是否删除了任何小时数，以便我也可以删除该记录。

我开始质疑自己，我的内联森林方法在这种情况下是否有效？

所以底线是我如何在这个表单中填充这些不相关的表单字段？

我愿意接受任何方法或想法来实现这一目标，并感谢您的帮助。

如果您发现我做错了什么，请随时纠正我，以便我学习。
