Nevermind, found a dirty solution besides have to restructure my entire
code-base to implement sql.NullString
I was having trouble when populating contacts (which is []contact) with the
individual query returns.
I went from...
contacts = append(contacts, contact)
To using...
nullString := ""
// - convert any fields with pointers to nil to pointers to a null string ¬
if contact.Email == nil {
contact.Email = &nullString
}
if contact.Phone == nil {
contact.Phone = &nullString
}
if contact.Ext == nil {
contact.Ext = &nullString
}
contacts = append(contacts, contact)
If anybody knows of a less-dirty way to handle this, or make that code
cleaner... please let me know. I don't like the way it's being handled
now, but at least it's working now. Thank you!
