tmpl.Execute和子文件golang

Question

I need help. I need to use "html/template"'s marking ({{.Title}}, example) in sub-files("article.html", example in my text):

// ...
type Page struct {
    Test string
}

type News struct {
    Page
    Title string
}

func main() {
    t, _ := template.ParseFiles(filepath+"core.tmpl", filepath+"article.tmpl")
    p := &News{
        Title: "TITLE",
        Page: Page{
            Test: "TITLE",
        },
    }
    t.Execute(wr, p)
}

Code in core.tmpl:

{{template "article"}}

Code in article.tmpl:

{{define "article"}}
{{.Title}}<br><br>
{{.Page.Test}}
{{end}}

Answer 1

In your core.tmpl you have to use

{{template "article" .}}

If you don't specify the . at the end, the template will be executed with nil data. Specifying the . will pass the value of . to the invoked template.

Quoting from the text/template package documentation, Actions section:

{{template "name"}}
    The template with the specified name is executed with nil data.

{{template "name" pipeline}}
    The template with the specified name is executed with dot set
    to the value of the pipeline.
