Ruby on rails rails单选按钮自动提交

我希望能够将图像对象的

：albumcover

设置为TRUE或FALSE。我如何使用ajax实现这一点，以便在选中单选按钮时提交？ 非常感谢

查看

<% @images.each do |image| %>
...
  <%= label(:albumcover, 'Set as Album Cover ', :style => "float: left;") %>
  <%= radio_button_tag(:albumcover, "cover", false, :id => :albumcover_tag) %>
...
<% end %>

尝试使用Ajax

$(function(){
$('#albumcover_tag').bind('click', function(){
    $.ajax({
        url: "<%= update_form_admin_album_images_path %>",
        data: $('#albumcover_tag').val(),
    }).success(function(){
        alert("success");
    });
});
});

$(function(){
$('#albumcover_tag').bind('click', function(){
    $.ajax({
        url: "<%= update_form_admin_album_images_path %>",
        data: $('#albumcover_tag').val(),
    }).success(function(){
        alert("success");
    });
});
});

create_table "images", :force => true do |t|
    t.string   "title"
    t.string   "description"
    t.datetime "date"
    t.integer  "album_id"
    t.integer  "image_id"
    t.binary   "picture"
    t.boolean  "albumcover"
  end
