使用button_to时为什么会出现错误？

Question

给我错误的代码行是：

<%= button_to 'Search', static_pages/gallery %>

错误是：

  

未定义的局部变量或方法`static_pages'

以下是我的路线：

match "/home" => "static_pages#home"
match "/gallery" => "static_pages#gallery"

get "static_pages/home"
get "static_pages/gallery"
post "static_pages/gallery"

Answer 1

这是无效的语法：

<%= button_to 'Search', static_pages/gallery %>

Ruby会查找不存在的变量static_pages和gallery。它应该是一个字符串：

<%= button_to 'Search', 'static_pages/gallery' %>
