Rails - Aug 2009 - has_one and new

Hi Folks,

I''m totally confused - I have 3 tables

search, pickup_search and dropoff_search

pickup_search and dropoff_search are nearly identical and each contain
the search_id key.

My Models are as follows.

class Search < ActiveRecord::Base
  has_one :pickup_search
  has_one :dropoff_search
end

class PickupSearch < ActiveRecord::Base
  belongs_to :searches
end

class DropoffSearch < ActiveRecord::Base
  belongs_to :searches
end

So what I want to do is create a new search, then a new pickup_search
and a new dropoff_search.

I tried in my controllers new method to do

  def new
    @search = Search.new
    @search.pickup_search.new
    @search.dropoff_search.new
  end

however it throws the error when creating a new pickup and dropoff
search

NoMethodError (You have a nil object when you didn''t expect it!

However if I change the relationship in search to has_many it works!!!

However for any given ''search'' there will only be one
pickup_search and
dropoff_Search so it shouldn''t be a has_many relationship... or am I
modelling this incorrectly

(FYI the pickup_search and dropoff_date contains date/destination info)

Any help much appreciated!

Peter
