I have an issue with Golang view template, I currently using lowercase in the struct properties to build the struct then passed it to the view as a map.
here is my Struct look like:
type User struct {
uid int
username, departname string
}
then I passed the collection of structs to the file view:
func (App *App) indexHander(w http.ResponseWriter, r *http.Request) {
rows, err := App.db.Query("SELECT * FROM userinfo")
checkErr(err)
t, _ := template.ParseFiles(App.folderpath + "/list.gtpl")
users := make([]User, 0) // define empty collection of users
for rows.Next() {
var uid int
var username string
var departname string
var created string
err = rows.Scan(&uid, &username, &departname, &created)
checkErr(err)
users = append(users, User{uid, username, departname})
}
t.Execute(w, users)
defer rows.Close()
}
and here is my view html code:
<html>
<head>
<title></title>
</head>
<body>
<ul>
{{ range . }}
<li>{{ .username }}</li>
{{ end }}
</ul>
</body>
</html>
Those code above gave me empty users data:
But however, using capitalize first letter in struct give me working result:
Struct
type User struct {
Uid int
Username, Departname string
}
html
<html>
<head>
<title></title>
</head>
<body>
<ul>
{{ range . }}
<li>{{ .Username }}</li>
{{ end }}
</ul>
</body>
</html>
it works now
Can somebody explain me this behavior ?
