Ruby on Rails

Hi there,

I have a model with following methods:

  # Permalink instead of ID
  before_create do |article|
    article.permalink = _permalink
  end
 
  def to_param
    permalink
  end

- permalink is a field in the database

Ok, but when i try to run tests the permalink is not created, but my controllers find the object by the permalink attribute, and this is nil in the tests
maybe the

@article = articles(:one)

does not create the permalink because it is not in the fixtures, and I do not want to have it there.

How can I deal with that?

Thanks,
Martin
