Thanks for your reply David!
My solution ended up something like this:
def it_should_grant_access(role, options)
request_index = proc do
get :index
response.success?
end
# ...
actions_from(options).each do |action|
request = instance_eval(&eval("request_#{action}"))
request.should be_true, "#{role} should have been granted access
to #{action}, but was not"
end
# ...
end
Not perfect, but it works.
Btw, I solved the "not-case" by flipping only and except and then just
call it_should_grant_access.
Thanks!
