模板模拟继承功能：

自定义方法：

revel.TemplateFuncs["block"] = func(blockName, tempName string, data map[string]interface{}) string {
        t, err := revel.MainTemplateLoader.Template(tempName)
        if err != nil {
            log.Errorln(err)
            return ""
        }

        var b bytes.Buffer
        err = t.Render(&b, data)
        if err != nil {
            log.Errorln(err)
            return ""
        }
        data[blockName] = string(b.Bytes())
        return ""
    }

创建模板页（命名为layout.html）：

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>{{if .tpl_title}}{{raw .tpl_title}}{{end}}</title>
    {{if .tpl_head}}{{raw .tpl_head}}{{end}}
</head>
<body>
    {{if .tpl_body}}{{raw .tpl_body}}{{end}}
</body>
</html>

页面：

{{block "tpl_body" "引入页.html" .}}
{{template "layout.html" .}}
