again I'm stuck. I've been experimenting with Golang using this page as a guide for templates to create a master page. I've managed to get the Go server up with my CSS and JS directories all updated correctly but I am only able to load the index.html page and not the about.html page. Github link here
I have already tried the solutions in here and here but no luck, both the about page and index page are in the same directory and share the same header, footer and navigation bar templates.
I have also tried parsing files manually with template.Must(template.ParseFiles("header.html", ..... and also tried executing with the .html in the name templ.ExecuteTemplate(w, "about.html", &Page{Title: "About TL;DR"}) which does not return an error but instead just loads a blank screen. Any help will be greatly appreciated, thank you in advance!
File directory:
servermain.go
package main
import (
"fmt"
"html/template"
"log"
"net/http"
"os"
"path/filepath"
"strings"
)
//Page title
type Page struct {
Title string
}
//------------------------------Global Variables-------------------------------------//
//Compile templates on start
var templ = ParseTemplates()
//ParseTemplates use for multi directory html parsing
func ParseTemplates() *template.Template {
t := template.New("Base")
err := filepath.Walk("./", func(path string, info os.FileInfo, err error) error {
if strings.Contains(path, ".html") {
_, err = t.ParseFiles(path)
fmt.Println(path)
if err != nil {
logger.Println(err)
fmt.Println(err)
}
}
return err
})
if err != nil {
panic(err)
}
return t
}
//logging
var errorlog *os.File
var logger *log.Logger
//---------------------------------------Page Handlers----------------------------------//
//Handler for homepage
func homepageHandler(w http.ResponseWriter, r *http.Request) {
fmt.Println("Home")
err := templ.ExecuteTemplate(w, "index", &Page{Title: "Welcome to TL;DR"})
if err != nil {
fmt.Println(err)
logger.Println(err)
http.Error(w, err.Error(), http.StatusInternalServerError)
}
}
//Handler for about page
func aboutHandler(w http.ResponseWriter, r *http.Request) {
fmt.Println("About")
err := templ.ExecuteTemplate(w, "about", &Page{Title: "About TL;DR"})
if err != nil {
fmt.Println(err)
logger.Println(err)
http.Error(w, err.Error(), http.StatusInternalServerError)
}
}
//Server log to file
func init() {
errorlog, err := os.OpenFile("serverlog.log", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666)
if err != nil {
fmt.Printf("Error opening file: %v", err)
os.Exit(1)
}
log.SetOutput(errorlog)
logger = log.New(errorlog, "\r\nTDLR : ", log.Lshortfile|log.LstdFlags)
}
func main() {
//--------------------------------------Routers-------------------------------------//
http.HandleFunc("/", homepageHandler)
http.HandleFunc("/index", homepageHandler)
http.HandleFunc("/about", aboutHandler)
http.Handle("/static/", http.StripPrefix("/static/", http.FileServer(http.Dir("static"))))
//---------------------------------------------------------------------------------//
//start server
fmt.Println("Starting server on port 9090")
logger.Println("Starting server on port 9090")
logger.Fatal(http.ListenAndServe(":9090", nil))
}
Error page
Also I noticed no matter what page I load it will always execute the homepageHandler after executing the aboutHandler as can be seen in the console.
Edit: Solved 20181215
Improper definition of the about.html template, change to {{define "about"}} solved the problem.
