In task G, when place the order without writing user information. I got this err ”’nil’ is not an ActiveModel-compatible object that returns a valid partial path.” It suppose I should get some information like “Name can’t be blank” |

I think the problem here is that cart object is nil. but I can’t figure out why it becomes nil. |

on application layout, do you have this surrounding the partial?
<% if @cart %> #<-- the juice
<%= hidden_div_if(@cart.line_items.empty?, id: 'cart') do %>
<%= render @cart %>
<% end %>
<% end %>
it basically tests for nil I missed it because I’m skipping the tests sections. It’s in the Ajax chapter. |

alternatively, add
@cart = current_cart
to order_controller, def create |
