Jesus Rodriguez is right about POST and GET, but if you really need the button you can simply override the default method:
Jesus Rodriguez对POST和GET是正确的，但是如果你真的需要按钮，你可以简单地覆盖默认方法：
<%= button_to "New User", new_user_path, :class => "button", :method => :get %>

The "link_to" is looking for a /users/new using GET.
“link_to”正在使用GET查找/ users / new。
The "button_to" is looking for a /users/new using POST
“button_to”正在使用POST查找/ users / new
If you create the routes for a controller using:
如果使用以下命令为控制器创建路由：
resources :user
By default, /users/new is a GET and not POST so, the second line doesn't find any route.
默认情况下，/ users / new是GET而不是POST，因此第二行找不到任何路由。
If you are thinking to change that action to POST I think that you should forget about it.
如果您打算将该操作更改为POST，我认为您应该忘记它。

Instead of forcing button_to to use a non-default method, you can also send a class to link_to.
您也可以将类发送到link_to，而不是强制button_to使用非默认方法。
<%= link_to "New User", new_user_path, :class => "button" %>

button_to defaults to POST, and link_to defaults to GET, this is why links_to worked. You can force button_to to use GET:
button_to默认为POST，link_to默认为GET，这就是links_to工作的原因。您可以强制button_to使用GET：
<%= button_to "New User", new_user_path, :class => "button", :method => :get %>
