Ruby-on-Rails-第一个在表单中选择的选项

如何选择第一个选项 options_from_collection_for_select

我有密码:

<%= f.select :state, options_from_collection_for_select(Estate.order(:name), :uf, :name), {}, :id => 'populate_cities' %>

我需要输出:

<select id="populate_cities" name="guide_dog_form[state]"><option value="AC">Acre</option>
<option value="Select one option" disabled selected>Select one option</option>
<option value="option1">Option 1</option>
<option value="option2">Option 2</option>
<option value="option3">Option 3</option>
</select>

有人能帮我吗?谢谢。
