post functional test failing - ruby-on-rails

Question

I am trying to create a functional test that tests the create method in one of my controllers. For the life of me, I cannot figure out why this is failing. I am getting one failure, and zero errors:
1) Failure:
test_should_create_order(OrdersControllerTest) [/Users/user/rails_work/depot/test/functional/orders_controller_test.rb:38]:
"Order.count" didn't change by 1.
<3> expected but was
<2>.
So, Im pretty sure this means that my functionals test was unable to make an Order. Here is my test:
setup do
#order = orders(:one)
end
test "should create order" do
assert_difference('Order.count') do
post :create, order: #order.attributes.slice(Order.accessible_attributes)
end
assert_redirected_to store_url
end
my orders fixture:
one:
name: Dave Thomas
address: MyText
email: dave#example.org
pay_type: Check
and my Order#create controller:
def create
#order = Order.new(params[:order])
#order.add_line_items_from_cart(current_cart)
respond_to do |format|
if #order.save
Cart.destroy(session[:cart_id])
session[:cart_id] = nil
format.html { redirect_to store_url, notice: 'Thank you for your order' }
format.json { render json: #order, status: :created, location: #order }
else
#cart = current_cart
format.html { render action: "new" }
format.json { render json: #order.errors, status: :unprocessable_entity }
end
end
end
Now, if I change the setup method in my functional test to:
#order = Order.create(orders(:one))
Instead of:
#order = orders(:one)
The failure disappears, but I get about 8 of these errors:
NoMethodError: undefined method `stringify_keys' for #<Order:0x007f8c62dbb960>
If anyone can help me fix this functional test, I would more than appreciate it. Any and all input is welcome.

Bottom line: assign each order attribute individually.
I'm not familiar with the 'mass assignment' vulnerability (new to Rails), but here (Pragmatic Forums) is a case of someone having difficulty with that specific test because of it.
Try spelling out each attribute of the order individually. Instead of
post :create, order: #order.attributes.slice(Order.accessible_attributes)
use
post :create, order: {
address: #order.address,
email: #order.email,
name: #order.name,
pay_type: #order.pay_type
}
The test as a whole will be this:
test "should create order" do
assert_difference('Order.count') do
post :create, order: { address: #order.address, email: #order.email, name: #order.name, pay_type: #order.pay_type }
end
assert_redirected_to store_path
end
