Comments form above comments

Question

How can i have a comments form above the comments themselves.

Works

@post = Post.find(params[:id])
@post.comments.each do |comment|
  comment.id
end
@post.comments.build
  # form here
end

Desired but fails

@post = Post.find(params[:id])
@post.comments.build
  # form here
end
@post.comments.each do |comment|
  comment.id
end

@comment = @post.comment.new

view

end

@post.comments.each do |comment|

end
