我正在尝试显示健身课程列表(瑜伽、普拉提等)。每种课程类型都有几个课程,所以我想将所有瑜伽课程和所有普拉提课程等分组。
我做了这个函数来截取切片并制作它的地图
func groupClasses(classes []entities.Class) map[string][]entities.Class {
classMap := make(map[string][]entities.Class)
for _, class := range classes {
classMap[class.ClassType.Name] = append(classMap[class.ClassType.Name], class)
}
return classMap
}
现在的问题是如何遍历它,根据http://golang.org/pkg/text/template/,您需要以.Key
格式访问它,我不知道密钥(除非我也传递了一个切片模板中的键)。如何在我的视图中解压缩此地图。
我目前只有
{{ . }}
显示如下内容:
