// base.html - dad or mum
{{outline "base"}}
<!doctype html>
<html lang="en">
..
<most important function="most important" class="base_main container">
{{template "content material" .}}
</most important>
</physique>
</html>
{{finish}}
// baby.html
{{outline "content material"}}
<ul class="list-group list-group-flush">
{{vary .Customers}}
<li class="list-group-item">

</li>
{{finish}}
</ul>
{{finish}}
When utilizing the essential template, the enumeration takes place (<!doctype html>) together with the information ( {{vary .Customers}} )
You do not want to outline the “dad or mum” templates. Simply the kid templates. Right here is my “base template” utilizing a number of baby templates
<!DOCTYPE html>
<html lang="en">
{{template "httphead"}}
{{template "physique" "residence"}}
{{template "icn"}} {{template "nav" "residence"}}
<most important>
{{template "hdr_top"}}
<article>
{{template "mst_home"}}{{template "det_empty"}}
</article>
</most important>
{{template "httpend"}}
</physique>
</html>
It’s not likely concerning the templates. However I additionally corrected them.
func Alluser(w http.ResponseWriter, r *http.Request) {
tpl := template.Should(template.ParseFiles("./tpl/alluser.html", "./tpl/base.html" ))
rows, err := db.Question("SELECT username, e-mail FROM customers")
if err != nil {
http.Error(w, "didn't choose * from customers", 500)
return
}
defer rows.Shut()
var albums []*UserList
for rows.Subsequent() {
knowledge := new(UserList)
err := rows.Scan(&knowledge.Username, &knowledge.Electronic mail)
if err != nil {
http.Error(w, http.StatusText(500), 500)
return
}
albums = append(albums, knowledge)
fmt.Println("knowledge", knowledge)
}
tpl.ExecuteTemplate(w, "base", albums)
if err = rows.Err(); err != nil {
http.Error(w, http.StatusText(500), 500)
return
}
}
It’s all concerning the for loop, you needed to get out of it.
{{template "./tpl/base.html"}}
{{block "content material" .}}
<ul class="list-group list-group-flush">
{{vary .}}
<li class="list-group-item">
identify: {{.Username}}, e-mail: {{.Electronic mail}}
</li>
{{finish}}
</ul>
{{finish}}
