Golang：无法将数组解码为ObjectID

Question

所以我有这个结构，当我从数据库将其解码为结构时，出现此错误cannot decode array into an ObjectID

type Student struct {
    ID           primitive.ObjectID   `bson:"_id,omitempty"`
    ...
    Hitches      []primitive.ObjectID `bson:"hitches"`
    ...
}

我正在使用此功能进行解码

func GetStudentByID(ID primitive.ObjectID) model.Student {

    // Filter
    filter := bson.M{"_id": ID}

    // Get the collection
    studentCollection := GetStudentCollection()

    // The object that it will return
    student := model.Student{}

    // Search the database
    err := studentCollection.FindOne(context.TODO(), filter).Decode(&student)

    if err != nil {
        fmt.Println("Student DAO ", err)  <----------- Error is output here
        return model.Student{}
    }

    return student
}

这里是MongoDB的屏幕截图

Answer 1

type Student struct {
    ID      primitive.ObjectID     `bson:"_id,omitempty"`
    ...
    Hitches [][]primitive.ObjectID `bson:"hitches"`
    ...
}
