rails 4, active record: appending to has_many :through does not create join model anymore?
hi folks.
on rails 4, can somebody confirm that pushing model instances onto a
has_many :through relation does not create the necessary join model anymore?
class Reader < AR::Base
belongs_to :post
belongs_to :person
end
class Post < AR::Base
has_many :readers
has_many :people, through: :readers
end
@post.people << Person.new
so, basically this is not working:

thanks.

You probably need to use "create" and not "new" so there is something to put in the foreign keys.
