Functional test, pls help!

Hi guys, recently encountered this funny problem which i really dunno
wat happen…

I have been trying on it for the past few days and just doesnt work.Hope
you guys can give me some enlightenment.

Problem:
The functional test doesnt seems to be able to recognise one of my
model, and when i run the test, it keeps giving me the error of"You have
nil object when you don’t expect it". I tried rake
clone_structure_to_test but it still dont work. Checked my controllers
code but it has a code that says :

@countryinfo = Country.find(:first,:conditions=>[“name =
?”,@params[‘country’]])

I dunno why the functional test just couldn’t seems to recognise this
statement and so i gives me error that i am using a nil object in the
view templates.

Here is the actual error given :

ActionView::TemplateError: You have a nil object when you didn’t expect
it!
The error occured while evaluating nil.two_letter_code
.
.
143: <input type=“hidden” name=“country” value="<%=
@coun tryinfo.two_letter_code

I dunno why the functional test just couldn’t seems to recognise this

view templates.
Have you loaded the countries fixtures?

In order for the fixtures to be loaded into the database in the first
place, there needs to be a ‘fixtures :countries’ line in your test case
(that’s assuming your fixtures file is called ‘countries.yml’, which
would be the default for an ActiveRecord class called Country).

Assuming you’ve got a country named ‘SG’ in your fixtures, try changing
your controller code from @params[‘country’] to params[:country].
You’re passing a symbol rather than a string as the key in the post
params, but looking for a string in your controller. I think that
should do it…

I tried it, and it still gives the same error… it just seems that the
functional test is not able to search for this model class (although it
works normally if i do manual testing eg. click through the website
myself)

things i have done : create fixtures,
change self.instantanized.fixtures to true in
test_helper.rb
checked that i have included “fixtures :countries”
in the
controller

anything more i can do??

thanks man, alex… your reply is fast!!

bao lee wrote:

YEAH!!! i solved the error!.. it seems that the error is due to the
fixtures not having the correct data and RoR doesnt seems to care to
tell you that it cannot locate in the fixtures. After adding the
appropriate data in fixtures and rerun, it works!

Special thanks to alex young for pointing it out… thanks thanks…

oh you are talking about that one… sure i have that, i tot you meant
the data inside the countries database… sorry for my
mis-understanding…

so it just output the error whenever it reachs the ‘post’ stage, not
even run the assert statement after it…

here is the snippet of my controller code:

class SignupControllerTest < Test::Unit::TestCase
fixtures :countries

def setup
@controller = SignupController.new
@request = ActionController::TestRequest.new
@response = ActionController::TestResponse.new
end

Replace this with your real tests.

def test_zipdial_correct_flow
get :default
assert_response :success

post :confirmation, { :name => 'burninglegion', :country => "SG" } 

,session
assert_response :success
end
end
