Greetings again: I'm simplifying the case I presented earlier regarding the use of has_many :through. I'm using DHH's example from "Persuing Beauty with Ruby On Rails". Here are his models: class Author < ActiveRecord::Base has_many :authorships has_many :books, :through => :authorships end class Book < ActiveRecord::Base has_many :authorships has_many :authors, :through => :authorships end class Authorship < ActiveRecord::Base belongs_to :author belongs_to :book end Here's the code sample he provides to exercise the new functionality: david, awrd = Author.find(1), Book.find(1) david.authorships.create( :book => awrd, :contribution => "partial", :written_in => "Denmark" ) david.authorships.first.written_in # => "Denmark" david.books.first # => awrd Ok, fine and good. So how do I remove the created authorship? The only way I have found is this: Authorship.find(:first, :conditions => ["author_id = ? and book_id = ?", david.id, awrd.id]).destroy That doesn't seem like the "Rails" way of doing things. I hoping that I am missing something. Can anyone help me?
