I want to devide a number in my template by 1000, so I wrote:
fm := template.FuncMap{"divideBy1000": func(a int) float64 {
return a / 1000
}}
t, err := template.ParseFiles("order.html")
if err != nil {
panic(err)
}
var processed bytes.Buffer
err = t.ExecuteTemplate(&processed, "page", struct {
Sender string
PushName string
OLines global.OrderDetailData
}{
Sender: sender,
PushName: pushName,
OLines: oLines})
if err != nil {
panic(err)
}
outputPath := "./attachements/index.html"
f, err := os.Create(outputPath)
if err != nil {
panic(err)
}
w := bufio.NewWriter(f)
w.WriteString(processed.String())
w.Flush()
Any in my template I’ve:
{{define "page"}}
<!DOCTYPE html>

{{end}}<br>
=====================<br>
Approximate value: {{.OLines.Order.Price.Total}}<br>
Approximate value in Thousands: {{divideBy1000 .OLines.Order.Price.Total}}<br>
</body>
</html>
{{end}}
By my template is not executed because if the statement at the end of the template:
{{divideBy1000 .OLines.Order.Price.Total}}
Which means the function divideBy1000 is not defined, which is correct as I do not know how to attach my function fm to the template:
fm := template.FuncMap{"divideBy1000": func(a int) float64 {
return a / 1000
}}
Any idea?
