Thank you. This is what I'm doing right now - creating an engine. Could you please explain me (of course if you know) how this code in the engine works. This is an example from Rails Engine tutorial (http://edgeguides.rubyonrails.org/engines.html#using-a-class-provided-by-the-application): attr_accessor :author_name belongs_to :author, class_name: "User" before_save :set_author private def set_author self.author = User.find_or_create_by(name: author_name) end I cannot understand how "author_name" parameter appears in the model. "author_name" parameter doesn't belong to model. It is from params, from a form. So somehow it has to be passed to the model. But how? attr_accessor is not attr_accessible. Why is it there? What does it mean? The table "posts" for the model Post is as follows: --------------------------------- | id | title | text | author_id | --------------------------------- So, the new @post has to be created this way: @author = User.new(...some params...) @post = Post.new(:title => "title", :text => "text", :author_id => @author.id) @post.save! But there is some "set_author" method. What is a magic is it with that "set_author" method and :author_name parameter? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
