Mongoose - Insert two collections : one is ID dependant of the other
The solution I found is to create my own unique Id rather to get the ID of a mongoose Object ...and use a JSON object:
data.items.forEach(function(item,index){ tracks.push({name : "myname1"}) ); //name is unique posts.push({trackId : track.name) );}Track.create(tracks, function(err){ console.log('err', err);}
