How about separately writing `new` `create` in comments_controller ?

I 'noticed that we can use different ways to create a comment.

  1. use the way in this video: @post.comments.new in posts/show, then call[@post, comment] in partial;

  2. use: form_for @post.comments.new do |f| in partial

another way is create a views/comments/new then write new method(@post = Post.find(params[:post_id]), @comment = @post.comments.new) in comments_controller, finally call @comment in view

I haven't seen the first way before. Is this shorthand method new to rails? Which one is more usual in production?
