title: Go-gorm mysql "unsupported type []string, a slice of string"
body: <p>I use gorm, and try to create transaction to mysql. I have a struct </p>
  
  <pre><code>type Game struct {
      Images []string
  }
  
  game := Game{Images: []string{"1.png", "2.png"}}
  
  db := Database()
  
  tx := db.Begin()
  
  if err := tx.Create(&amp;game).Error; err != nil {
      tx.Rollback()
      return errors.New("Cannot add game")
  }
  
  tx.Commit()
  </code></pre>
  
  <p>But I get error <code>(sql: converting argument $1 type: unsupported type []string, a slice of string)</code>. I understand, that mysql unsupported this type, but can I someway resolve this problem? I guess I can change type to <code>json.rawMessage</code>, but I think it's a wrong way.</p>
  
  <p>I use dialect <code>"github.com/jinzhu/gorm/dialects/mysql"</code></p>
