搜索表单不会显示

Question

我尝试从railsCast＃37创建一个示例搜索表单： railscasts.com/episodes/37-simple-search-form

我的文字字段看起来不可见或隐藏。这是我的代码：

查看：

get {
  (path("token") & parameters("email", "password")) { (email, password) =>
    complete {
      DBManager.getUserByEmail(email) map {
        case Some(user) =>
          UserWire(user)
        case None => 
          StatusCodes.NotFound -> "User doesn't exist"
      }
    }
  }
}

控制器：

<div>
<% form_tag 'mainbase', :method => 'get' do %>
  <p>
    <%= text_field_tag :search, params[:search] %>
    <%= submit_tag "Search", :name => nil %>
  </p>
<% end %>

型号：

 @students = Student.search(params[:search])

你错过了等号。

<%= form_tag 'mainbase', :method => 'get' do %>
