I'm attempting to send a slice containing many structs to an html template.
I have a 'post' struct
type Post struct {
threadID int
subject string
name string
text string
date_posted string
}
I create a slice of type Post ( posts := []Post{} )
this slice is then populated using rows from my database and then executed on my template.
defer latest_threads.Close()
for latest_threads.Next(){
var threadID int
var subject string
var name string
var text string
var date_posted string
latest_threads.Scan(&threadID, &subject, &name, &text, &date_posted)
post := Post{
threadID,
subject,
name,
text,
date_posted,
}
posts = append(posts, post)
}
t, error := template.ParseFiles("thread.html")
if error != nil{
log.Fatal(error)
}
t.Execute(w, posts)
}
The program compiles / runs okay but when viewing the html output from the template
{{.}}
{{range .}}
<div>{{.threadID}}</div>
<h3>{{.subject}}</h3>
<h3>{{.name}}</h3>
<div>{{.date_posted}}</div>
<div><p>{{.text}}</p></div>
<br /><br />
{{end}}
{{.}} outputs just fine however upon reaching the first {{.threadID}} in {{range .}} the html stops.
<!DOCTYPE html>
<html>
<head>
<title> Test </title>
</head>
<body>
//here is where {{.}} appears just fine, removed for formatting/space saving
<div>

It's not really intuitive, but templates (and encoding packages like JSON, for that matter) can't access unexported data members, so you have to export them somehow:
// directly export fields
type Post struct {
ThreadID int
Subject, Name, Text, DatePosted string
}
// expose fields via accessors:
type Post struct {
threadID int
subject, name, text, date_posted string
}
func (p *Post) ThreadID() int { return p.threadID }
func (p *Post) Subject() string { return p.subject }
func (p *Post) Name() string { return p.name }
func (p *Post) Text() string { return p.text }
func (p *Post) DatePosted() string { return p.date_posted }
(this part is mandatory regardless of which option you chose from above)
{{.}}
{{range .}}
<div>{{.ThreadID}}</div>
<h3>{{.Subject}}</h3>
<h3>{{.Name}}</h3>
<div>{{.DatePosted}}</div>
<div><p>{{.Text}}</p></div>
<br /><br />
{{end}}
And this should work.
