How to pass html from sql query to structure with type template.HTML?

Question

go

There is a structure

type NewsData struct {
  Id       int    // id новости
  Uid      int   
  Pt       int    
  Title    string // заголовок новости
  Post     template.HTML // текст новости
  Time     time.Time // время создания или изменения
}

when receiving a response from the database

var n NewsData
err := rows.Scan(&n.Id, &n.Uid, &n.Pt, &n.Title, &n.Post, &n.Time)

Gives an error message :

Scan error on column index 4: unsupported Scan, storing driver.Value type []uint8 into type *template.HTML

Changing to string type is not very convenient, because it will complicate the logic.
How can this error be avoided?

Answer 1

Describe the structure, implement Scan and Value for it.
The format of the structure is something like template.HTML + Valid bool, but I don’t know if it will work.
