使用async在节点js中执行循环后执行一些函数

Question

module.exports= {
  getHomePost:function(req,res) {
    post_model.getHomePosts('1',function(err,rows) {
      var locals={}; 
      async.parallel([
        function(callback) {
          for(var i=0;i<rows.length-1;i++) {
            async.series([ 
              function(call){
                post_model.getPostDetails(rows[i].Post_Date_Time_id,rows[i].Post_Personid_id,function(err,row) {
                  locals.rows[]=row;
                  call();
               });
              }  
            ],function(err){ 

            //console.log(locals.rows);
            });
          } 
          callback();
        }
      ],function(err) {
        console.log(locals.rows);
        res.render('home',locals);
      });
    });
  }
}

＆＃34;我想在从for循环获取输出后执行渲染。但我无法做到这一点..请帮忙＆＃34;
