ruby-on-rails - Rails 简单表单给出了 InvalidAuthenticityToken 错误

Question

我有一个像这样的简单表格:

<form name="serachForm" method="post" action="/home/search">   
  <input type="text" name="searchText" size="15" value="">
  <input class="image" name="searchsubmit" value="Busca" src="/images/btn_go_search.gif" align="top" border="0" height="17" type="image" width="29">
</form>

以及具有此方法的 Controller :

  def busca
    puts params[:searchText]
  end

当我单击表单中的图像按钮时，我得到一个 ActionController::InvalidAuthenticityToken。这是完整的 StackTrace:

怎么了？

沿着 Nat 的路线，添加

<%= token_tag %> 

就在 HTML“表单”标签起作用之后
