All of a sudden, I’m getting this error:

1. Error:  
test\_index(AccountControllerTest):  
RuntimeError: The number of parameters does not match the number of  
substitutions.  
/home/joe/projects/tanga/trunk/config/…/vendor/rails/actionpack/lib/action\_controller/assertions.rb:92:in  
`assert_redirected_to' /home/joe/projects/tanga/trunk/config/../vendor/rails/actionpack/lib/action_controller/assertions.rb:313:in`clean\_backtrace’  
/home/joe/projects/tanga/trunk/config/…/vendor/rails/actionpack/lib/action\_controller/assertions.rb:74:in  
`assert_redirected_to' ./test/functional/account_controller_test.rb:16:in`test\_index’

I thought it happened when I upgraded to Rails 1.1.4, but it happens  
now when I downgrade to 1.1.2.

Here’s test/functional/account\_controller\_test.rb:  
class AccountControllerTest \< Test::Unit::TestCase  
def setup  
@controller = AccountController.new  
@request = ActionController::TestRequest.new  
@response = ActionController::TestResponse.new  
end

def test\_index  
get :index  
assert\_redirected\_to :action =\> ‘login’ # LINE 16  
end

def test\_login  
get :login  
assert\_valid\_markup  
end  
end

Any ideas?

Thanks,  
Joe

Anyone?

Rails is not being nice to me at the moment. On another machine,  
running Ubuntu Dapper, I’m getting:

When I run my unit tests. I’ve installed Ruby 1.8.4 into /usr/local.  
I’ve got a copy of Rails 1.1.4 in vendor/rails.

I am having zero luck with anything.

Migrations (using postgres) don’t work:

The second issue was fixed by manually installing the ruby-postgres  
binding. For some reason, the gem didn’t work.

And I’m using postgres-pr because even after I installed the postgres  
gem, rubygems couldn’t find it.
