Has_many :through does it support collection_singular_ids?


#1

Good evening list members,

I have the following model:

class Author < ActiveRecord::Base
has_many :authorships
has_many :books, :through => : authorships
end

Should I be able to do the following?

Author.find(:first).book_ids = [1,2,3]

I ask, because it doesn’t. The docs state that it should, but it
doesn’t specialise in the case of a :through

This works fine BTW:

Author.find(:first).authorship_ids = [12,13]

Do I really need to find and add (<<) my associated join models for
books one by one?
