*assigns* - _Any objects that are stored as instance variables in
actions for use in views._
(http://guides.rubyonrails.org/testing.html#the-four-hashes-of-the-apocalypse)
I have a code :-
test "should update line_item" do
patch :update, id:@line_item, line_item: {
cart_id:@line_item.cart_id, product_id:@line_item.product_id}
assert_redirected_to line_item_path(assigns(:line_item))
end
Does *assigns(:line_item)* give back an instance of the model _LineItem_
? I am bit confused with the use of the method *assigns*.
