At the moment, when you compose a post and redirect to the root route, sometimes the post is not yet saved and doesnt show up on the home page.

Goal: Add a callback to the save method to only redirect to the home page once save is complete with no errors.

Scroll down if you need a hint

• Youll need to add a call back to the mongoose save() method.

post.save(function(err){

if (!err){

res.redirect("/");

}

});
