内部循环定义父链接

Question

我想循环我的表的名称以添加由符号“ _”定义的关联。

如果表a_b然后存在a则, 。最后，我不必打印名称中包含“”的表ba = [b]b = [a]_

结构体

// Table with Fields and Assoc

type Table struct {

    Name       string

    Assoc      []Assoc

}

// Assoc is a name of associated Table

type Assoc struct {

  Name string

}

tables := []string{

    "a",

    "b",

    "c",

    "d",

    "f",

    "a_b",

    "a_c",

    "a_d_f",

    "c_d",      

}

var tbls []Table

for _, t := range tables {

    if strings.Contains(t, "_") {

        // Split to find "_" like assoc := strings.Split(t, "_") ?

        // append in struct "Table{Name:a, Assoc:  [b,c,d,f]}"

        // append in struct "Table{Name:b, Assoc:  [a]}"

        // append in struct "Table{Name:c, Assoc:  [a,d]}"

        // append in struct "Table{Name:d, Assoc:  [a,c,f]}"

        // append in struct "Table{Name:f, Assoc:  [a,d]}"      

    } else {

        n := Table{

            Name: t,

        }

        tbls = append(tbls, n)

    }

}

像这样返回fmt.Println(tbls)：

[{a [b,c,d,f]} {b [a]} {c [a,d]} {d [a,c,f]} {f [a,d]}]
