页面html如下：

<div class='control-group'>
                <label class='control-label' for='email'>电子邮件</label>
                <div class='controls'>
                    <input class='input-xlarge readonly' id='email' name='email' size='30' type='text' readonly='true' value='<%= email %>' />
                </div>
            </div>
            <div class='control-group'>
                <label class='control-label' for='profile'>个人简介</label>
                <div class='controls'>
                    <% if(locals.profile){ %>
                    <textarea class='input-xlarge' id='profile' name='profile' rows='4'><%= profile %></textarea>
                    <% }else{ %>
                    <textarea class='input-xlarge' id='profile' name='profile' rows='4'></textarea>
                    <% } %>
                </div>
            </div>

nodejs代码如下：

      var method = req.method.toLowerCase();
  if (method !== 'post') {
    get_user_by_id(req.session.user._id, function (err, user) {
      if (err) {
        return next(err);
      }
      if (req.query.save === 'success') {
        user.success = '保存成功。';
      }
      user.error = null;
      return res.render('user/setting', user);
    });
    return;
  }

nodejs中并没有render各个值进去啊，只是render了user对象。是如何取到值的呢？登陆的时候存到session中了吗？
