【问题描述】:
我的应用中有一个购物车控制器
class CartsController < ApplicationController
def show
@cart = Cart.find(session[:cart_id])
@products = @cart.products
end
end
并编写了测试cartscontroller_spec.rb
RSpec.describe CartsController, type: :controller do
describe 'GET #show' do
let(:cart_full_of){ create(:cart_with_products, products_count: 3)}
before do
get :show
end
it { expect(response.status).to eq(200) }
it { expect(response.headers["Content-Type"]).to eql("text/html; charset=utf-8")}
it { is_expected.to render_template :show }
it 'should be products in current cart' do
expect(assigns(:products)).to eq(cart_full_of.products)
end
end
end
我的 factory.rb 看起来是这样的:
factory(:cart) do |f|
f.factory(:cart_with_products) do
transient do
products_count 5
end
after(:create) do |cart, evaluator|
create_list(:product, evaluator.products_count, carts: [cart])
end
end
end
factory(:product) do |f|
f.name('__product__')
f.description('__well-description__')
f.price(100500)
end
但我有一个错误:
FCartsController GET #show should be products in current cart
Failure/Error: expect(assigns(:products)).to eq(cart_full_of.products)
expected: #<ActiveRecord::Associations::CollectionProxy [#<Product id: 41, name: "MyProduct", description: "Pro...dDescription", price: 111.0, created_at: "2016-11-24 11:18:43", updated_at: "2016-11-24 11:18:43">]>
got: #<ActiveRecord::Associations::CollectionProxy []>
由于产品模型数组 ActiveRecord::Associations::CollectionProxy [] 为空,看起来我根本没有创建产品,同时,我调查产品的 id 随着每次测试尝试而增加。目前我没有实体错误的想法
