英文:
gotemplate not rendering data
问题
func renderTemplate(w http.ResponseWriter, tmpl string, data interface{}) {layout := "static/layout.html"tmplFiles := []string{layout, tmpl}fmt.Printf("%v\n", data)t, err := template.ParseFiles(tmplFiles...)if err != nil {http.Error(w, err.Error(), http.StatusInternalServerError)return}err = t.ExecuteTemplate(w, "layout.html", data)if err != nil {http.Error(w, err.Error(), http.StatusInternalServerError)return}}func main(){http.HandleFunc("/directors", directorsHandler)fs := http.FileServer(http.Dir("static"))http.Handle("/static/", http.StripPrefix("/static/", fs))fmt.Println("Server listening on port 8080...")http.ListenAndServe(":8080", nil)}directors.html{{ define "content" }}Directors ----<h1>{{ .Title }}</h1><ul>{{ range .Directors }}hi<li><p><strong>Name:</strong> {{ .Name }}</p><p><strong>Date of Birth:</strong> {{ .DateOfBirth }}</p><p><strong>Nationality:</strong> {{ .Nationality }}</p></li>{{ end }}</ul>{{ end }}func directorsHandler(w http.ResponseWriter, r *http.Request) {data := struct {Title stringDirectors []struct {Name stringDateOfBirth stringNationality string}}{Title: "Director List",Directors: []struct {Name stringDateOfBirth stringNationality string}{{Name: "Christopher Nolan",DateOfBirth: "July 30, 1970",Nationality: "British",},{Name: "Quentin Tarantino",DateOfBirth: "March 27, 1963",Nationality: "American",},// Add more directors as needed},}renderTemplate(w, "static/directors.html", data)}
不知道为什么 .Title 没有被渲染出来。
我怀疑是因为接口的原因，但没有找到相关的信息。
我使用匿名结构体将不同的数据发送到不同的页面。
我尝试将信息发送到 directors.html 模板的内容，但它不会被渲染出来。
更多细节：
数据被发送到 data interface{}。
英文:
func renderTemplate(w http.ResponseWriter, tmpl string, data interface{}) {layout := "static/layout.html"tmplFiles := []string{layout, tmpl}fmt.Printf("%v\n", data)t, err := template.ParseFiles(tmplFiles...)if err != nil {http.Error(w, err.Error(), http.StatusInternalServerError)return}err = t.ExecuteTemplate(w, "layout.html", data)if err != nil {http.Error(w, err.Error(), http.StatusInternalServerError)return}}func main(){http.HandleFunc("/directors", directorsHandler)fs := http.FileServer(http.Dir("static"))http.Handle("/static/", http.StripPrefix("/static/", fs))fmt.Println("Server listening on port 8080...")http.ListenAndServe(":8080", nil)}directors.html{{ define "content" }}Directors ----<h1>{{ .Title }}</h1><ul>{{ range .Directors }}hi<li><p><strong>Name:</strong> {{ .Name }}</p><p><strong>Date of Birth:</strong> {{ .DateOfBirth }}</p><p><strong>Nationality:</strong> {{ .Nationality }}</p></li>{{ end }}</ul>{{ end }}func directorsHandler(w http.ResponseWriter, r *http.Request) {data := struct {Title stringDirectors []struct {Name stringDateOfBirth stringNationality string}}{Title: "Director List",Directors: []struct {Name stringDateOfBirth stringNationality string}{{Name: "Christopher Nolan",DateOfBirth: "July 30, 1970",Nationality: "British",},{Name: "Quentin Tarantino",DateOfBirth: "March 27, 1963",Nationality: "American",},// Add more directors as needed},}renderTemplate(w, "static/directors.html", data)}
don't know why .Title is not being rendered.
i have the suspicion that its because the interface but didn't find anything about it.
i am using anonymous struct to send different data to different pages.
I tried to send information to directors.html template content but it wont render.
more details:
the data is being send to data interface{} .

得分: 1
在发送数据到具有布局的页面时发现问题，你需要写成{{template "content" .}}而不是{{ template "content" }}。需要添加一个点。
英文:
Problem found when sending data to a page with layout you need to write {{template "content" .}} instead of {{ template "content" }}.
needed to add a dot.
