arrays - 如何使用映射分配结构类型值？

Question

我想创建一个多维数组，如下所示:

[string][int] = Struct

我编写了以下代码块。当我尝试将 Struct 类型分配给 map 时，出现以下错误:

cannot use event (type *models.Event) as type map[int]models.Event in assignment go

代码块来了:

//Get func
func (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()
}

这里有什么问题？

正如 Marc 定义的那样，我更新了代码块，如下所示。现在它完美无缺!

//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()
}
