错误：注销链接中未定义的局部变量或方法“删除”

Question

我正在创建一个登录-注销链接。 我已经为用户使用了我的设计，并收到以下错误。

显示/home/sushmitha/ground/remote_modals_demo-master/app/views/layouts/_header.html.erb，其中第9行出现：

＃<＃：0x00007f3920c61e38>的未定义局部变量或方法'delete'

//_header.html.erb

<header class="navbar navbar-fixed-top navbar-inverse">
      <div class="container">
        <h1><%= link_to "Cricket", root_path, id: "logo" %></h1>
        <nav>
          <ul class="nav navbar-nav navbar-right">
            <li><%= link_to "Home",   root_path %></li>
            <li><%= link_to "Help",   '#' %></li>
            <% if  user_signed_in? %>
            <li><%= link_to "Sign out", destroy_user_session_path, method:delete %></li>
            <% else %>
            <li><%= link_to "Log in", user_session_path %></li>
            <% end %>
          </ul>
        </nav>
      </div>
    </header>
