Hi, I have this controller method that I need to test: def link_concept_to_client concept_to_link = Concept.find(params[:concept_id]) # take all the variations for the concept for variation in concept_to_link.variations new_client_variation = ClientVariation.new new_client_variation.client = session[:active_client] new_client_variation.variation = variation new_client_variation.name_fr = variation.name_fr new_client_variation.name_en = variation.name_en new_client_variation.save end flash[:notice] = "Concept linked" redirect_to(:action => "list") end it is working fine when I use it in dev, but when I run this test (see next), it fails: def test_link_concept #create a new concept new_concept = Concept.new new_concept.name = "concept a lier" new_concept.description = "ce concept va etre lie" new_concept.save #give it a variation new_variation = Variation.new new_variation.name_fr = "nom de la variation" new_variation.description = "name of the variation" new_variation.concept_id = new_concept.id new_variation.save #link it to the client get :link_concept_to_client, {:concept_id => new_concept.id}, {:active_client => clients(:air_canada)} #there should now be a client_variation for the variation assert_not_nil ClientVariation.find_by_variation_id(new_variation.id) assert_equal new_variation.name_fr, (ClientVariation.find_by_name_fr new_variation.name_fr).name_fr end Sorry for the blooted code, I had to decompose everything in small part to locate the problem... The error message is: NoMethodError: You have a nil object when you didn''t expect it! The error occured while evaluating nil.name_fr specific_controller_test.rb:45:in `test_link_concept'' The weird thing is that the first assert works which means that there is something in the DB for that record, but the second assertion doesnt work. Anyone has an idea? Thanks a lot! -- Posted via http://www.ruby-forum.com/.
