英文:
html/template: "layout" is undefined
问题
我尝试使用martini框架和布局模板：
package main
import (
"github.com/go-martini/martini"
"github.com/martini-contrib/render"
)
func main() {
m := martini.Classic()
m.Use(render.Renderer(render.Options{Directory: "./templates",
Layout: "layout",
Extensions: []string{".tmpl"},
}))
m.Get("/", func(r render.Render) {
r.HTML(200, "mainPage", map[string]interface{}{"Title": "some title", "H1": "some h1"})
})
m.Run()
}
在与main.go文件相同的文件夹中，我有一个名为templates的文件夹，里面有一个layout.tmpl文件：
<html xmlns="http://www.w3.org/1999/xhtml"></html>
<head></head>
<body>
<div id='left'>
{{template "left" .}}
</div>
<div id='right'>
{{template "right" .}}
</div>
</body>
还有一个mainPage.tmpl文件：
{{define "left"}}
left content
{{end}}
{{define "right"}}
right content
{{end}}
当我在浏览器中打开http://localhost:3000/时，我看到错误消息：html/template: "layout" is undefined。
英文:
I try to use martini framework with layout template:
package main
import (
"github.com/go-martini/martini"
"github.com/martini-contrib/render"
)
func main() {
m := martini.Classic()
m.Use(render.Renderer(render.Options{Directory: "./templates",
Layout: "layout",
Extensions: []string{".tmpl"},
}))
m.Get("/", func(r render.Render) {
r.HTML(200, "mainPage", map[string]interface{}{"Title": "some title", "H1": "some h1"})
})
m.Run()
}
In the same folder as this main.go file I got folder templates with layout.tmpl file:
<html xmlns="http://www.w3.org/1999/xhtml"></html>
<head></head>
<body>
<div id='left'>
{{template "left" .}}
</div>
<div id='right'>
{{template "right" .}}
</div>
</body>
and mainPage.tmpl file:
{{define "left"}}
left content
{{end}}
{{define "right"}}
right content
{{end}}
When I open http://localhost:3000/ in browser I see error:
html/template: "layout" is undefined

我的问题是我从随机目录中运行了go文件。为了解决这个问题，我将目录（cd）更改为templates文件夹的上级目录。
英文:
My problem was that I run go file from random directory. To solve it I changed directory (cd) to parent of templates folder.

在</body>之后添加正确的html闭合标签
就是这样：
英文:
<html xmlns="http://www.w3.org/1999/xhtml"></html>
<head></head>
<body>
<div id='left'>
{{template "left" .}}
</div>
<div id='right'>
{{template "right" .}}
</div>
</body>
Make correct html close tag after </body>
That`s it:
<html xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body>
<div id='left'>
{{template "left" .}}
</div>
<div id='right'>
{{template "right" .}}
</div>
</body>
</html>
