I'm following "Agile web development with rails" book. I have a problem.
this is my new
method in order
controller:
def new
@cart = current_cart
if @cart.line_items.empty?
redirect_to store_url, notice: "Your cart is empty"
return
end
@order = Order.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @order }
end
end
And this is the test:
test "should get new" do
cart = Cart.create
session[:cart_id] = cart.id
li = LineItem.create(product: products(:ruby))
li.cart = cart
get :new
assert_response :success
end
the rake test
shows a failure:
Expected response to be a <:success>, but was <302>
I checked it with rails command line as follows:
cart = Cart.create
=> #<Cart id: 24, created_at: "2012-07-09 08:39:36", updated_at: "2012-07-09 08:39:36">
products = Product.create(:title => "Lorem Ipsum", :description => "Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem", :price => 49.50, :image_url => "ruby.png")
=> #<Product id: nil, title: "Lorem Ipsum", description: "Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem", image_url: "ruby.png", price: #<BigDecimal:434f108,'0.495E2',18(45)>, created_at: nil, updated_at: nil>
li = LineItem.create(product: products)
=> #<LineItem id: 106, product_id: nil, cart_id: nil, created_at: "2012-07-09 08:41:29", updated_at: "2012-07-09 08:41:29", quantity: 1, price: nil, order_id: nil>
li.cart = cart
=> #<Cart id: 24, created_at: "2012-07-09 08:39:36", updated_at: "2012-07-09 08:39:36">
li.cart
shows the corresponding cart
, but cart.line_items
is empty. the two model (carts and line_items) and related to each other. why is the cart.line_items
empty?

or just use write_attribute or update_attribute
li.write_attribute :cart, cart

save
your list item after assigning it the cart.
test "should get new" do
cart = Cart.create
session[:cart_id] = cart.id
li = LineItem.create(product: products(:ruby))
li.cart = cart
li.save! // Do this and make sure it doesn't raise an exception.
get :new
assert_response :success
end
Just assigning will not register the change in the database and hence @cart.line_items
will remain empty. Thus, in your controller the if check will redirect. 302 code is for redirection.
