The Update function

The Update function invokes the ExecuteTemplate method with writer and customer looked up by id. The ExecuteTemplate method renders the UPDATE template:

// Update - execute template
func Update(writer http.ResponseWriter, request *http.Request) {

  var customerId int
  var customerIdStr string
  customerIdStr = request.FormValue("id")
  fmt.Sscanf(customerIdStr, "%d", &customerId)
  var customer Customer
  customer = GetCustomerById(customerId)

    template_html.ExecuteTemplate(writer,"Update",customer)

}
