目前我正在使用fields_for通过一个提交按钮提交多个表单（同一个对象）。一切都很好，只有一件事是我的单选按钮。由于fields_for为我的所有单选按钮创建了相同的名称组，因此每当我选择单选按钮时，其他表单中的单选按钮的值将被取消选中。因此，现在我想为每个表单中的单选按钮创建一个唯一/动态名称。 我的方法是我想在视图中创建变量索引，然后，每当我点击“add_inquery”时，按钮，索引变量将增加1。但是现在的第一个问题是我不知道为单选按钮的名称分配的语法。第二个问题，我如何使用Jquery更新索引变量，以便单选按钮将获得一个唯一的名称，如
<input class="non_bco" name="radio_button_group_1" type="radio" value="false" id="pricing_history__bco_false">
<input class="non_bco" name="radio_button_group_2" type="radio" value="false" id="pricing_history__bco_false">
<input class="non_bco" name="radio_button_group_3" type="radio" value="false" id="pricing_history__bco_false">
