如何获取数据库中单选按钮的选中值？

Question

<%= radio_button_tag(:gender, "male") %>    
<%= label_tag(:male, "Male") %>    
<%= radio_button_tag(:gender, "female") %>    
<%= label_tag(:female, "Female") %>

我创建了一个单选按钮。我正在尝试在我的数据库中获取检查的值。我得到的结果像

参数：

{
    "authenticity_token" => "", "contact_details" => {
        "name" => "kjhg", "address" => "fds", "state_id" => "2", "email" => "asdfghjk@lkfd.com", "number" => "0987654321"
    }, "gender" => "female", "commit" => "Create"
}

那个单选按钮字段在我的表格之外。如何在我的表中获取该字段并将结果反映在数据库中？

您必须根据您需要的参数更改 radio_button_tag 的 name 属性。

<%= radio_button_tag("contact_details[gender]", "male") %>    
<%= label_tag(:male, "Male") %>    
<%= radio_button_tag("contact_details[gender]", "female") %>    
<%= label_tag(:female, "Female") %>
