Sorry, I don't know what that means, and I still can't solve my
original problem, which led to the test code in my op. Here is what I
have now:
class StoreController < ApplicationController
def index
@products = Product.find(:all)
end
def add_to_cart
@cart = [1, 2, 3]
end
end
layouts/store.html.erb

<% for num in cart -%>
<div><%= num %></div>

When I go to http://localhost:3000/store in my browser, I get this:
-------------
NoMethodError in Store#index
Showing app/views/store/_cart.html.erb where line #1 raised:
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each
Extracted source (around line #1):
1: <% for num in cart -%>
2: <div><%= num %></div>
3: <% end %>
