Question

I have a recursively nested schema just like comments work on a blog. What is the best way to pull an individually nested document out which may be several layers deep.

I understand that you get the root document out, then drill down to the document you want, but in a recursive situation where the wanted document may be an unknown number of levels deep how should I retrive it. Loop through and do an if to see if its the correct one…?

Answer 1

looks like there is no mongoose way to do it so im using a recursive find function like this for finding a folder which is nested:

var findFolder = function(searchFolder ,folder_id, cb){
  var folder = searchFolder.folders.id(folder_id);
  if(folder == undefined){
    _.each(searchFolder.folders, function(subFolder){
      findFolder(subFolder, folder_id, cb);
    }.bind(this))
  }else{
    cb(folder);//when found callback passing the doc
  };
};

p.s. this uses the underscore library
