如何删除id＆amp; rails视图助手的名称属性

Question

默认情况下，Rails会从name参数为select_tag生成id和名称：

select_tag "people", "<option>David</option>".html_safe
# => <select id="people" name="people"><option>David</option></select>

但是如果我们想要生成select而没有id和name属性呢？
像这样：

<select><option>David</option></select>

空名称参数不起作用，空的html属性仍然存在：

select_tag "", "<option>David</option>".html_safe
# => <select id name><option>David</option></select>

手动id和name分配不起作用

select_tag "people", "<option>David</option>".html_safe, id: false, name: false
# => <select id=false name=false><option>David</option></select>
select_tag "people", "<option>David</option>".html_safe, id: '', name: ''
# => <select id name><option>David</option></select>

Answer 1

id和name可以通过为其分配nil来删除：

select_tag nil, "<option>David</option>".html_safe, id: nil
# => <select><option>David</option></select>
