Forum: Italian Ruby user group Helper Select

Utilizzando l'helper select in questo modo

select("post", "category", Post::CATEGORIES, {:include_blank => true})

ottengo:

  <select name="post[category]">
    <option></option>
    <option>joke</option>
    <option>poem</option>
  </select>

Come devo utilizzare lo stesso helper per ottenere

  <select name="post[category]">
    <option value=""></option>
    <option value="0">joke</option>
    <option value="1">poem</option>
  </select>
