私のデータが
db.posts.save({postid:1,postdata:"hi am ",comments:["nice","whats bro"]});
したがって、この場合、コメントを反復する方法は
cursor=selct * from posts; cursor 1=selct * from comments where postid=:cursor.postid for (i in cursor) for(j in cursor1)
コメントを反復処理する 1 つの方法は次のとおりです。
db.posts.find().forEach( function(doc) { // iterate over the comments in your preferred javascript way var i; for (i=0; i<doc.comments.length; ++i) { // Do whatever you want with doc.comments[i] here } } )
