我的应用程序中有路由问题，但我不明白为什么。 我希望有人可以解释为什么会这样。
非常感谢你的帮助。
<%= 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：
没有路线匹配[POST]“/ de / restaurants / 526fe01e65617271ea000000”

默认情况下，button_to会在link_to获取后发布帖子。所以你想要这个
<%= button_to 'Show', restaurant_path(restaurant), :id => 'button_show_restaurant', :class => 'btn btn-success', :method => :get %>
