Hi, Jakob Borg
Thanks for ypur reply to the post. The solution you have provided can not
be implemented on my system. I have provided a small sample of my code
structure. Please take a look
type EmailTemplate struct{
BookingDetails string
}
type EmailRequest struct{
EmailTo string
EmailBody string
}
// get saved html with tokens from database
notificationTemplate, errVal := merchantDb.GetNotificationTemplate()
request := EmailRequest{
"t...@example.com",
notificationTemplate.Content,
}
templateData.BookingDetails +=
"<p><span>Industry</span><span>"+industry.IndustryName+"</span></p>"
request.EmailSend(templateData)
func (request *EmailRequest) EmailSend(notificationTemplateData
interface{}) (bool, error) {
body, errParse := ParseTemplate(request.EmailBody,
notificationTemplateData)
//email sending code here
}
func ParseTemplate(templateHtml string, data interface{}) (string,
error) {
var body string
t, err := template.New("my_template").Parse(templateHtml)
if err != nil {
return body, err
}
buf := new(bytes.Buffer)
if err = t.Execute(buf, data); err != nil {
return body, err
}
body = buf.String()
return body, nil
}
Where templateHtml is the email body with tokens and data is the interface
holding dynamic values for these tokens.
When I use ParseTemplate function to parse tokens as string values then it
works fine.
But if I have to parse html in one of my tokens then it parses html as
string and in email displays html as string.
How ever If I try to make assertion on it from interface to template.HTML,
it gives me error:
cannot convert notificationTemplateData (type interface {}) to type
"html/template".HTML: need type assertion
