Rails の f.date_select とかで class を追加したい場合の件

Rails2.3.6, Ruby1.9.3
twitter-bootstrap 使用

class 追加前の例

  <div class="field">
    <%= f.label :start_date, "日程" %>
    開始<%= f.date_select :start_date, include_blank: true, selected: @hoge.start_date} %><br />
    終了<%= f.date_select :end_date, include_blank: true, selected: @hoge.end_date %>
  </div>

RoR リファレンスで調べる

date_select(method, options = {}, html_options = {})
Ruby on Rails API

解決の例

{}で括ればよいらしい

  <div class="field">
    <%= f.label :start_date, "日程" %>
    開始<%= f.date_select :start_date, {include_blank: true, selected: @hoge.start_date}, {:class => "input-mini"} %><br />
    終了<%= f.date_select :end_date, {include_blank: true, selected: @hoge.end_date}, {:class => "input-mini"}  %>
  </div>
