Validate uniqueness depends on record

[rejeep]

Hi!

I have this Request model that I want to test a little bit different
depending on an attribute. The attribute is *local*. So if a Request
is local, I don't want to validate uniqueness of *url*. But I do want
that if the Request is global.

So I thought I would do it like this:
class RequestTest < ActiveSupport::TestCase
subject { Factory(:request) }

context "a local request" do
setup { subject { Factory(:request, :local => true) } }

# No uniqueness validation
end

context "a global request" do
setup { subject { Factory(:request, :local => false) } }

should_validate_uniqueness_of :url
end

# ...
end

But this does not work.

I also tried to stub the subject block:
context "a global request" do
setup do
request = Factory(:request, :local => false)
stubs(:subject).returns(request)
end

should_validate_uniqueness_of :url
end

But no success there either...

Do you know how to solve this?

Thanks!

You don't show any error messages, so I'm not too sure. I believe #subject is a class method, so you'd do it this way:

context "a global request" do

subject do
@subject ||= Factory(:request, :local => false)
end

should_validate_uniqueness_of :url
end

RDoc for #subject: http://rdoc.info/rdoc/thoughtbot/shoulda/blob/21ce037d1228a5f56deac79c55049e33f8dda5ae/Shoulda/ClassMethods.html#subject-instance_method

Hope that helps!

Sorry if I was unclear. There's no error, but the test fails with
this:
Expected errors to include "has already been taken" when url is set to
"http://domain.com", got no errors

Your suggestion didn't work.

Maybe there's a better way to do it? What I'm trying to test is this:
validates_uniqueness_of :url, :unless => :local?
validates_uniqueness_of :url, :if => :local?, :scope => :user_id
