遍历模板中的地图 [英] Iterating through map in template

问题描述

我正在尝试显示健身课程清单(瑜伽，普拉提等).对于每个班级类型，都有几个班级，因此我想将所有瑜伽班和所有普拉提班归为一组.

I am trying to display a list gym classes (Yoga, Pilates etc). For each class type there are several classes, so I want to group all the Yoga classes, and all the Pilates classes and so on.

我使用了此功能来切片并绘制地图

I made this function to take a slice and make a map of it

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
}

根据 http://golang.org/pkg/text/template，问题现在是如何遍历它/，您需要以.Key格式访问它，我不知道键(除非我也将一部分键传递到模板中).如何在我的视图中解包此地图.

The problem is now how can I iterate through it, according to http://golang.org/pkg/text/template/, you need to access it in .Key format, I don't know the keys (unless I also passed a slice of keys into the template). How do I unpack this map in my view.

我目前只有

{{ . }} 

显示如下内容:

推荐答案

检查变量部分在Go模板文档中.范围可以声明两个变量，以逗号分隔.以下应该可以工作:

Check the Variables section in the Go template docs. A range may declare two variables, separated by a comma. The following should work:

{{ range $key, $value := . }}
   <li><strong>{{ $key }}</strong>: {{ $value }}</li>
{{ end }}
