我想創(chuàng)建一個多維數(shù)組，如下所示：[string][int] = Struct我編寫了以下代碼塊。當(dāng)我嘗試將結(jié)構(gòu)類型分配給映射時，出現(xiàn)以下錯誤：無法在賦值 go 中使用事件（類型 *models.Event）作為類型 map[int]models.Event這是代碼塊：//Get funcfunc (c *EventController) Get() { days := [7]string{"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"} m := make(map[string][]map[int]models.Event) for _, day := range days { var i = 0 o := orm.NewOrm() qs := o.QueryTable("events") qs.OrderBy("id") qs.Filter("days__name", day) var events []*models.Event num, err := o.QueryTable("events").RelatedSel().All(&events) if err == nil { fmt.Printf("%d events read\n", num) for _, event := range events { m[day][i] = event i++ } } else { fmt.Println(err) } } c.Data["json"] = m // c.TplName = "events.tpl" c.ServeJSON()}這里有什么問題嗎？

正如 Marc 所定義的，我更新了代碼塊，如下所示?，F(xiàn)在它完美運(yùn)行了！
//Get func
func (c *EventController) Get() {
days := [7]string{"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"}
m := make(map[string][]*models.Event)
for _, day := range days {
o := orm.NewOrm()
var events []*models.Event
num, err := o.QueryTable("events").Filter("day__name__exact", day).RelatedSel().All(&events)
fmt.Print("Day: ", day, " Count:", num, "\n")
if err != nil {
fmt.Printf("%d posts read\n", num)
}
m[day] = events
}
c.Data["json"] = m
// c.TplName = "events.tpl"
c.ServeJSON()
}
