Phoenixで選択項目の使用（Select Box / Radio Button）

Phoenix でよく使うので覚え書き。

selectタグの場合

form.html.eex

  <div class="form-group">
    <%= label f, :gender, class: "control-label" %>
    <%= select f, :gender_cd, ["男性": "1", "女性": "2", "その他": "0"], class: "control-label" %>
  </div>

radio button タグの場合

form.html.eex

  <div class="form-group">
    <%= label f, :gender, class: "control-label" %>
    <%= radio_button f, :gender_cd, "1", checked: true, class: "control-label" %>男性
    <%= radio_button f, :gender_cd, "2", class: "control-label" %>女性
    <%= radio_button f, :gender_cd, "0", class: "control-label" %>その他
  </div>
