Question

I want to allow the user and nonlogin visitors to create posts, but have trouble in coding
In ruby on rails tutorial, I find:
@post =current_user.posts.build(params[:post])
But the curren_user would be nil.
Another approach is
@post.user = current_user
This seems ok
but is this line too ugly? should I need to create a guest user to put those posts into it?

You could do this, assuming you are using devise:

application_controller.rb

class ApplicationController < ActionController::Base
  before_filter :set_current_user

  def set_current_user
    #create a new use if there is no logged in user
    #or you could probably load a default user
    current_user = User.new unless user_signed_in?  
  end 
end
