Rails fixtures load not working as stated (2.3.4)

as staed in the API, I am loading fixtures into a table :

rake db:fixtures:load FIXTURES=ecourses without specifying the id in a simple has_many/belongs_to association, and I get an 'unknow column' error for the foreign_key... if I change the FK to a label interpolation, then I got it running well....

I am using the following tset code : Models-------------- class Epath < ActiveRecord::Base    has_many :ecourses end

class Ecourse < ActiveRecord::Base    belongs_to :epath end

Fixtures--------------- # epaths complexPath:   name: Complex One

# ecourses.yml curabitur:   name: Curabitur   epath: complexPath

error : Mysql::Error: Unknown column 'epath' in 'field list' : INSERT INTO `ecourses` (`epath`,......

BUT if I modify the Fixtures

# ecourses.yml curabitur:   name: Curabitur   epath_id: <%= Fixtures.identify(:complexPath) %>

then I got it done ....

what's wrong in my code ?

tfyh
