I'm having trouble with one particular thing I'm trying to put through Go html templates.
(all will be condensed/simplified for brevity)
I have one base template:
<html>
<head>
<title>{{ .Title }}</title>
</head>
<body>
{{ template .PageBody . }}
</body>
</html>
And a device template:
{{ define "device" }}
<div class="nav">
<div class="links">
{{ .DeviceLinkList }}
</div>
</div>
<div class="textData">
<div class="deviceNick">
{{ .Nickname }}
</div>
</div>
{{ end }}
The way I set this up is like so:
In the main.go file:
package main
import "html/template" //among others, of course.
var err error
var tmplInit *template.Template
type TemplVals struct{
Title string
Version string
Release string
PageBody string
}
var templVals TemplVals
func init(){
// Prepare GOHTML templates
tmplInit, err = template.ParseGlob("./html_templates/*.gohtml")
if err != nil { log.Panic("Cant load templates! ", err) }
templVals.Version = serverDetails["version"]
templVals.Release = serverDetails["release"]
}
//Main only has MUX routing using Gorilla Mux
In the deviceController.go file:
type DeviceValues struct{
DeviceLinkList string
Nickname string
Title string
}
func home(w http.ResponseWriter, r *http.Request){
w.Header().Set("Content-Type", "text/html; charset=utf-8")
var deviceData DeviceValues
// Seems to not be loaded as HTML when passed to template?
deviceData.DeviceLinkList = loadDeviceList("example")
deviceData.Nickname = loadDeviceData("example")
deviceData.PageBody = "device"
deviceData.Title = "Home"
tmplErr := tmplInit.Execute(w, deviceData)
if tmplErr != nil{ log.Panic(tmplErr) }
}
func loadDeviceList(user string)(string){
var deviceid, linkList string
linkList = `<ul>`
for getIDs.Next(){
err = getIDs.Scan(&deviceid) // SQL gathers this
if err != nil { panic(err) }
linkList = linkList + `<li><a href="#" onclick="loadDevice('`+deviceid+`')">`+deviceid+`</a></li>`
}
linkList = linkList + `</ul>`
return linkList
}
func loadDeviceData(user string)(string){
//SQL retrieves data for devices associated to passed in user
//for brevity:
return "Example Nickname"
}
The problem is the nickname is loaded properly, and there are other fields such as battery levels and sensor readings that all pass through properly and can even be used in JS functions, but the DeviceLinkList is rendered in regular string no matter what I do. It's not a list, just pukes out the HTML as-is in plain text.
