Question

Here is the rspec error message:

  5) CustomersController GET customer page 'show' should be successful
     Failure/Error: get 'show' , :id => customer.id
     ActionView::Template::Error:
       undefined method `name' for nil:NilClass
     # ./app/views/customers/show.html.erb:43:in `_app_views_customers_show_html_erb___16283441_33497004'
     # ./spec/controllers/customers_controller_spec.rb:41:in `block (3 levels) in <top (required)>'

name is one column in customer model.

Error above caused by the spec code for customers controller:

it "'show' should be successful" do
  customer = Factory(:customer)
  get 'show' , :id => customer.id
  response.should be_success
end

The ‘show’ in customer controllers is :

  def show
    @customer = Customer.find(params[:id])
  end

Any thoughts about the error? Thanks.

Answer 1

The error (undefined method 'name' for nil:NilClass) is coming from your show view, line 43.

     # ./app/views/customers/show.html.erb:43:in 

and it’s because you’re calling something.name when something is nil.
