How to pass the value of a constant to a struct tag?

Question

go

There is a code:

const (
  MIN = 60 * 10
  MAX = 60 * 24 * 24 * 30
)

type Item struct {
  Seconds int `valid:"required,range(MIN|MAX)"`
}

func NewItem(seconds int) (*Item, error) {
  item := &Item{
    Seconds: seconds,
  }

  _, err := govalidator.ValidateStruct(item)
  if err != nil {
    return nil, fmt.Errorf(err.Error())
  }

  return item, nil
}

Is it possible to pass the value of constants (MIN,MAX) to the "valid" tag?
Something like this:

Seconds int `valid:"required,range(${MIN}|${MAX})"`

Answer 1

No, structure tag is a string literal.

Answer 2

Unless through the generator to make the generation already with the specified values, but it will still be a simple string literal. So only through the generator if there are many similar values.
