如何使用form_for录制此内容？
<div class="form-group">
<div class="cc-selector">
<%= f.radio_button :priorities, id: "yellow", name: "priorities", value: '1'%>
<input id="a" type="radio" name="priorities" value=1/>
<label class="priorities-cc yellow" for="a"></label>
<input id="b" type="radio" name="priorities" value=2/>
<label class="priorities-cc orange" for="b"></label>
<input id="c" type="radio" name="priorities" value=3/>
<label class="priorities-cc red" for="c"></label>
<input id="c" type="radio" name="priorities" value=4/>
<label class="priorities-cc fair" for="d"></label>
</div>
</div>
我试过了，这不行 其他字段存储在数据库中 ＆lt;％= f.radio_button：is_code，[a，1，b，2，c，3，d，4]％＆gt;
非常感谢你的帮助！

我看到所有其他input代码都有integer个值，但在f.radio_button中，您将value设置为'1'，这是<%= f.radio_button :priorities, 1, id: 'yellow', class: 'priorities-cc fair', for: 'd' %>
一个字符串，您可以检查您的验证或该属性等待接收的数据类型。
尝试：
value注意parameter的第二个radio_button或controller[attribute]是它将采用的值，名称将是控制器，括号*<html>
