我需要帮助。我在数组测验选项中有表单标签按钮。当价值答案为1时，我需要检查真实答案。
<%= radio_button_tag('quiz_en_option[is_answer][]',"1",quiz_option_en.is_answer) %>True
<!-- <input id="quiz_en_option_is_answer__1" type="radio" value="1" name="quiz_en_option[is_answer][]" checked="checked"> -->
答案 0 :(得分：0)
radio_button_tag(name, value, checked = false, options = {})
# if quiz_option_en.is_answer is 1 it will get checked else unchecked
<%= radio_button_tag('quiz_en_option[is_answer][]',"1",quiz_option_en.is_answer.eql?(1) %>True
答案 1 :(得分：0)
我现在得到真实答案，名字不应该是数组。
<%= radio_button_tag('quiz_en_option[is_answer]', i.to_s, quiz_option_en.is_answer, id: "answer_" + i.to_s, class: "en-answer-radio" ) %>True
