I have been working with restful\_authentication. I have made some changes to it and now I’m trying to get all the default tests that came with the plugin to pass. Here’s one of the tests that error out: def test\_should\_require\_login\_on\_signup assert\_no\_difference ‘User.count’ do create\_user(:login =\> nil) assert assigns(:user).errors.on(:login) assert\_response :success end end This is the error: NoMethodError: You have a nil object when you didn’t expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.errors When using running debugger and checking in on assigns(:user) it returns nil, so I assume this is the trouble. Finally here’s my question, what is “create\_user” doing? Is it creating a new User based upon the users.yml fixture that the test suit is loading, or is it something else? I couldn’t find reference for this “dynamic??” method anywhere. Thanks ---

Any thoughts on this? Basically, I just need to know what “create\_user” is doing? Is it creating a new User based upon the users.yml fixture that the test suit is loading, or is it something else? I couldn’t find reference for this “dynamic??” method anywhere. def test\_should\_require\_login\_on\_signup assert\_no\_difference ‘User.count’ do create\_user(:login =\> nil) assert assigns(:user).errors.on(:login) assert\_response :success end end ---

If you look down the end of the file with that code in you will find the definition of create\_user. At least in my version anyway. I found it by a global search, but I realised when it found it that I should have looked in that file first. 2009/3/27 elliottg [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

It looks like I have a “Filter chain halted” error going on that is not allowing the user to be created. Thanks for all the help. ---

I can’t help with this as I have tweaked the create code so it is non-standard. Is there a before\_filter in UsersController, if so then it may be failing in there. 2009/3/27 elliottg [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Doh… I just found it, right after my last post. Thanks for getting back to me. I am assuming that somehow @user is being returned or something? Because, assigns(:user) is being called on the next line?? Is that the case, and further any ideas why its coming up Nil? Testing in script/console test shows that creating a new User works fine and I know the fixture data is in the users table as it should be? Thanks a ton ---

A before\_filter redirect in role\_reqirement\_system#access\_denied is halting things before the create action of the user controller could be called. Not really sure how test around this as the redirect is a key part of how r\_r works. Any thoughts on getting around situations like this? Thanks ---

I don’t know about role\_requirement\_system I am afraid, so only guesswork follows. If I understand correctly the problem is that the restful authentication tests are failing because the role requirement conditions are not satisfied by the test conditions. Possibly you have to adjust the test fixtures and possibly test code so that the users in the fixtures have appropriate roles to satisfy the tests. 2009/3/29 elliottg [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)
