我想用一个表单组创建多个示例。所以我可以编辑formgroup中的earnedmarks。
请查看图像文件

Let data = [
{
    "_id" : ObjectId("60ae48f11bc8e43ab0b485d6"),
    "rubrics" : [ 
        {
            "description" : "",
            "totalMarks" : 10,
            "earnedMarks" : 0
        }, 
        {
            "description" : "",
            "totalMarks" : 10,
            "earnedMarks" : 0
        }, 
        {
            "description" : "",
            "totalMarks" : 10,
            "earnedMarks" : 0
        }
    ]
},
{
    "rubrics" : [ 
        {
            "description" : "",
            "totalMarks" : 100,
            "earnedMarks" : 0
        }
    ]

}
]
