Question

I'm working through the latest version of Michael Hartl's tutorial, and I have the following message:

Failures:

1) UserPages edit with valid information Failure/Error: sign_in user NoMethodError: undefined method sign_in' for #<RSpec::Core::ExampleGroup::Nested_4::Nested_4::Nested_3:0x9f1b1bc> # ./spec/requests/user_pages_spec.rb:66:in block (3 levels) in '

The same message nine times.

I ran green until "Updating users".

In the 9.2 I have changed the following programs as they were mention in the tutorial. I was trying and trying for more than 10 hours and finally I gave up. Would you please, help me.

Answer 1

This is telling your that the sign_in method has not been defined. You need to add in in utilities.rb as per 9.6 in the tutorial
