这个是post-content的代码

<div class="post-content">
    <div class="ui grid">
        <div class="four wide column">
            <a class="avatar"
               href="/posts?author={{author._id }}"
               data-title="{{author.name }}"
               data-content="{{author.bio }}">
                <img class="avatar" src="/img/{{author.avatar}}">
            </a>
        </div>

        <div class="eight wide column">
            <div class="ui segment">
                <h3><a href="/posts/{{_id}}">{{title }}</a></h3>
                <pre>{{{content}}}</pre>
                <div>
                    <span class="tag">{{created_at }}</span>
                    <span class="tag right">
            <span>浏览({{ pv }})</span>
            <span>留言({{ commentsCount }})</span>

            {{#if user}}
                <div class="ui inline dropdown">
                <div class="text"></div>
                <i class="dropdown icon"></i>
                <div class="menu">
                  <div class="item"><a href="/posts/{{_id }}/edit">编辑</a></div>
                  <div class="item"><a href="/posts/{{_id }}/remove">删除</a></div>
                </div>
              </div>
            {{/if}}
          </span>
                </div>
            </div>
        </div>
    </div>
</div>

这个是外面的循环posts

{{#each posts}}
    {{>post-content}}
{{/each}}

user不是循环里面的东西，数据是posts数组和一个user对象， 在外面的posts模板可以获取到user,里面就获取不到了，怎么样才能去获取
