我正在使用最新版本的Solidus電子商務（Spree的分叉），我遇到此問題。要快速形容它：Solidus：在after_save回調中執行的代碼返回rspec中的錯誤
- 在聯繫我在施普雷創建施普雷::會員記錄
- after_save的回調::成員創造產品和2個變種
當我運行的服務器此代碼的工作，但是，當我試圖使用Rspec的它給我這個錯誤：
Failure/Error: reload.product.setup_membership_variants
NoMethodError:

這裏是我使用的代碼：
membership.rb
class Spree::Membership < Spree::Base
has_many :active_memberships, class_name: 'Spree::ActiveMembership', dependent: :destroy
has_one :membership_product, class_name: "Spree::MembershipProduct", dependent: :destroy
has_one :product, through: :membership_product, source: :product
validates :name, presence: true
validates :monthly_quota, presence: true
validates :price, presence: true
after_save :setup_product
private
def setup_product
if product.nil?
ActiveRecord::Base.transaction do
create_membership_product(
product: Spree::Product.create(
name: name,
price: price,
shipping_category: Spree::ShippingCategory.find_by(name: "Default")
)
)
reload.product.setup_membership_variants
end
else
product.update(name: name, price: price)
end
end
end
product_decorator.rb
Spree::Product.class_eval do
def setup_membership_variants
ot = Spree::OptionType.find_or_create_by(name: "Membership")
option_types << ot
if ot.option_values.empty?
["Monthly", "Yearly"].each do |freq|
ot.option_values.create(name: freq, presentation: freq)
end
end
month = variants.create(is_master: false, price: price, track_inventory: false)
month.option_values << Spree::OptionValue.find_by(name: "Monthly")
year = variants.create(is_master: false, price: price * 12, track_inventory: false)
year.option_values << Spree::OptionValue.find_by(name: "Yearly")
end
end
membership.rb factory
FactoryGirl.define do
factory :membership, class: Spree::Membership do
name {FFaker::Lorem.word}
monthly_quota { rand(10..200) }
price { rand(10..200) }
trait :unnamed do
name nil
end
trait :without_quota do
monthly_quota nil
end
trait :priceless do
price nil
end
end
end
example of controller test
require 'rails_helper'
RSpec.describe Spree::PremiumController, type: :controller do
let(:valid_membership) { create(:membership) }
let(:variant) { create(:master_variant) }
context "#show" do
it "returns http success" do
get :show
expect(response).to have_http_status(:success)
end
it "returns all memberships" do
get :show
expect(assigns[:memberships]).to include(valid_membership)
end
end
context "#create" do
let!(:store) { create(:store) }
context "user not logged" do
context "valid attributes" do
context "user doesn't exist in database" do
subject do
post(:create, params: {
premium: {
first_name: "Ondrej",
last_name: "Kubala",
email: "[email protected]",
password: "test123",
password_confirmation: "test123",
membership_id: valid_membership.id,
payment_frequency: "1", #monthly yearly is 2
cc_number: "4111111111111111",
cc_exp_date: "10/22",
cvv: "123"
}
})
end
it "creates user with valid attributes" do
expect { subject }.to change { Spree::User.count }.from(0).to(1)
end
it "logs in user" do
expect(controller.warden).to receive(:set_user)
subject
end
context "create order with variant" do
it "should handle population" do
expect { subject }.to change { Spree::Order.count }.by(1)
user = Spree::User.find_by email: "[email protected]"
order = user.orders.last
expect(response).to redirect_to go_premium_path
expect(order.line_items.size).to eq(1)
# line_item = order.line_items.first
# expect(line_item.variant_id).to eq(valid_membership.reload.product.variants.)
end
it "charges credit card"
it "should redirect to account page"
end
end
context "user already exists"
end
context "wrong user attributes" do
end
context "wrong payment attributes" do
end
end
context "user is logged in" do
let(:user) { create(:user) }
before do
allow(controller).to receive_messages try_spree_current_user: user
allow(controller).to receive_messages spree_current_user: user
end
it "doesn't create user"
end
end
end
我沒有在Rspec的太多的經驗，但它的怪異，它當服務器在運行，開發工作，但在測試中它給了我那個錯誤。
任何想法是什麼錯？
