My background is python/django so in python we have serializer to decide which field should be proccessed from request body and which field should be return in response body
I can’t find something like this in golang/gin/gorm
and I see their are many people doesn’t recommend DTO (data transfer object).
so is their library or prefered pattern in go to serializer & deserialize data ?

cases:
if I have endpoint /user/:id/update/
I want to ignore password field even if user sent it.

if I have endpoint /user to list all user
I didn’t want to add password field in response.

try 1: I tired to use json:"-" but i think it’s not prefect because I will have another endpoint to update user password

try 2 :
I created generic function to set value of specific fields to null and add omitempty to all fields
I’m not sure it’s prefect solution or not

func ToStruct[T any](s T, flds []string) T {
    elem := reflect.ValueOf(s).Elem()
    for i:=0; i<elem.NumField(); i++ {
        if  slices.Contains(flds, elem.Type().Field(i).Name) {
            f  := elem.Field(i)
            if f.Kind() == reflect.Ptr {
                // Set the field value to nil
                f.Set(reflect.Zero(f.Type()))
            } else {
                // Set the field value to its zero value}
            f.SetZero()
            }
        }
        
    }
    return s
}
