獲取內部結構值

Question

在這個例子中 ，我將Sql driver更改為mgo ，我有些困惑。 在這里，我如何訪問內部struct值？ 喜歡嵌套的結構。

我有兩個結構，

作者

type Author struct {
    ID        string `bson:"id"`
    Name      string `bson:"name"`
    Timestamp time.Time
}

文章

type Article struct {
    ID        bson.ObjectId `bson:"_id,omitempty"`
    Title     string        `bson:"title"`
    Content   string        `bson:"content"`
    Author    Author        `bson:"inline"`
    Timestamp time.Time
}

功能

func (m *mgoArticleRepository) FindAll() ([]*models.Article, error) {
    result := make([]*models.Article, 0)
    sessionCopy := m.Conn.Copy()
    defer sessionCopy.Close()
    collection := sessionCopy.DB(DBNAME).C(COLLECTION)
    err := collection.Find(nil).All(&result)
    return result, err
}

產量

作者對象返回空（我在mongoDB中有數據）

[
    {
        "ID":"5b4f27c187a9e40828422cca",
        "Title":"Makan Ayam",
        "Content":"Sample values One",
        "Author":{
            "ID":"",
            "Name":"",

        },
        "Timestamp":"0001-01-01T00:00:00Z"
    },
    {
        "ID":"5b4f27c187a9e40828422ccb",
        "Title":"Makan Ikan",
        "Content":"Sample values Two",
        "Author":{

            "Name":"",

        },
        "Timestamp":"0001-01-01T00:00:00Z"
    },
    {

        "Title":"Makan Sayur",
        "Content":"Sample values Three",
        "Author":{
            "ID":"",
            "Name":"",
            "Timestamp":"0001-01-01T00:00:00Z"
        },
        "Timestamp":"0001-01-01T00:00:00Z"
    },
    {
        "ID":"5b4f27c187a9e40828422ccd",
        "Title":"Makan Daging",
        "Content":"Sample values Four",
        "Author":{
            "ID":"",
            "Name":"",
            "Timestamp":"0001-01-01T00:00:00Z"
        },
        "Timestamp":"0001-01-01T00:00:00Z"
    },
    {
        "ID":"5b4f27c187a9e40828422cce",
        "Title":"Makan Indomie",
        "Content":"Sample values Five",
        "Author":{
            "ID":"",
            "Name":"",
            "Timestamp":"0001-01-01T00:00:00Z"
        },
        "Timestamp":"0001-01-01T00:00:00Z"
    },
    {
        "ID":"5b4f27c187a9e40828422ccf",
        "Title":"Makan Soto",
        "Content":"Sample values Six",
        "Author":{
            "ID":"",
            "Name":"",
            "Timestamp":"0001-01-01T00:00:00Z"
        },
        "Timestamp":"0001-01-01T00:00:00Z"
    }
  ]

在這里，我如何建立兩個結構的關系？ 謝謝。

Answer 1

改變線：

Author Author `bson:"inline"

至

Author Author `bson:"Author"`
