我的应用程序中的路由有问题，但我不明白为什么。我希望有人能解释我为什么会这样。
非常感谢您的帮助。
<%= link_to 'Show', restaurant_path(restaurant), :id => 'button_show_restaurant', :class => 'btn btn-success' %>
<%= button_to 'Show', restaurant_path(restaurant), :id => 'button_show_restaurant', :class => 'btn btn-success' %>
link_to 代码正确路由到所需的餐厅，但 button_to 产生以下内容：
