Question

I’m working on this tutorial(time is 33:55): http://net.tutsplus.com/tutorials/ruby/the-intro-to-rails-screencast-i-wish-i-had/

While what is shown at localhost:3000 is correct and functions properly, I’m still getting an rspec error. Thanks for any suggestions!

Ruby 1.9.2p290
Rails 3.2.3
RSpec 2.11.0

Answer 1

I believe that by doing this assignment…

current_path = edit_task_path(@task)

…you created a new variable called ‘current_path’ which overwrote capybara’s.

The moral of the story is don’t assign to ‘current_path’
