Capybara Rspec integration test link_to POST gives back ActionView::Template::Error:

It' my first time working with capybara and Rspec together for integration testing. I was able to link around a couple of routes and fill in the required fields from the form. Everything up to "visit webinars_path" in my spec works ok.

The trouble I am encountering is this line "click_link 'Register Now' " link. It gives me the error:

Failure/Error: find_link('Register Now', :href => '/webinars/test-webinar/register').click ActionView::Template::Error: undefined method `permalink' for nil:NilClass

I am assuming this means that @webinar is nil, however when I debug this in the Registration controller (see below registrations_controller.rb), using puts @webinar.permalink It logs back 'test-webinar' which is the webinar I want to register for. So, I know that registrations#new is passing, but it can't get past that to registraions#create. Can anyone help me solve this error, wondering why @webinar is nil.
