nodejs建站-回复评论

评论回调方法提取用户名

exports.detail=function(req,res){
	var id=req.params.id
	Movie.findById(id,function(err,movie){
	 	Comment.find({movie: id},function(err,comments){
	 		console.log(comments)
	 		res.render('detail',{
			title:movie.title,
			movie:movie,
			comments:comments
			// {title:'momo',
			// country:'USA',
			// year:'2014',
			// flash:'http://www.imooc.com/video/1226/0',
			// summary:'你好试试'}
		})
	 	})
	})
}

使用populate获取用户名

exports.detail=function(req,res){
	var id=req.params.id
	Movie.findById(id,function(err,movie){
	 	Comment.find({movie: id})
	 		.populate('from','name')
	 		.exec(function(err,comments){
	 		console.log(comments)
	 		res.render('detail',{
			title:movie.title,
			movie:movie,
			comments:comments
			// {title:'momo',
			// country:'USA',
			// year:'2014',
			// flash:'http://www.imooc.com/video/1226/0',
			// summary:'你好试试'}
		})
	 	})
	})
}

与其有关联的对象设置为replay

comment中初始化： movie,from.,replay,mata,content，to

修改to为

	replay:{
		from:{type:ObjectId,ref:'User'},
		to:{type:ObjectId,ref:'User'},
		content:String 
		},	

在jade文件中对用户图片添加锚点#comments

将所有的回复加到主评论的回复中，实现对子回复的回复
