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>
以及具有此方法的控制器：
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 的思路，添加
<%= token_tag %>
就在 HTML“form”标签起作用之后
