求帮助playframework一个小问题

Question

我在用play1.27做一个练习时遇到些问题

这个是controller下的index方法中代码，查询数据

这两个是实体类User用户和Post文章

用了test测试代码没问题，

以下是页面代码
#{extends 'main.html' /}
#{set title:'Home' /}

#{if frontPost}

${frontPost.title}

by ${frontPost.author.fullname}
${frontPost.postedAt.format('MMM dd')}

 | 
${frontPost.comments.size() ?: 'no'}
comment${frontPost.comments.size().pluralize()}
#{if frontPost.comments}
, latest by ${frontPost.comments[-1].author}
#{/if}

${frontPost.content.nl2br()}

#{if olderPosts}
    <div class="older-posts">    
        <h3>Older posts <span class="from">from this blog</span></h3>

        #{list items:olderPosts, as:'oldPost'}
            <div class="post">
                <h2 class="post-title">
                    <a href="#">${oldPost.title}</a>
                </h2>
                <div class="post-metadata">
                    <span class="post-author">
                        by ${oldPost.author.fullname}
                    </span>
                    <span class="post-date">
                        ${oldPost.postedAt.format('dd MMM yy')}
                    </span>
                    <div class="post-comments">
                        ${oldPost.comments.size() ?: 'no'} 
                        comment${oldPost.comments.size().pluralize()}
                        #{if oldPost.comments}
                            - latest by ${oldPost.comments[-1].author}
                        #{/if}
                    </div>
                </div>
            </div>
        #{/list}
    </div>

#{/if}

#{/if}

#{else}

There is currently nothing to read here.

#{/else}
