在我的应用程序中，借助 Cancan，我允许客户访问他自己的优惠。
当我用浏览器“手动”尝试时它有效但我未能实施 rspec 测试。客户无法访问其他客户的交易，只能访问他自己的交易（管理员通过 Active Admin 界面授予他访问权限）。
就像我没有设法让 rspec 理解我为测试创建的客户（通过 FactoryGirl）应该被允许/与我为测试创建的交易（再次通过 FactoryGirl）相关联。
测试：/spec/controllers/deals_controller_spec.rb
require 'spec_helper'
require "cancan/matchers"
describe DealsController do
context "As signed-in CUSTOMER" do
before do
@customer = FactoryGirl.create(:customer) #the factory builds a basic customer i.e with 'prospect role' attributed by default
@deal = FactoryGirl.create(:deal, :customers => [@customer]) # in array as a deal has_many customers
sign_in_customer @customer
end
describe "the customer can read=view the page of a Deal HE OWNS " do
it "can access the page" do
get :deal_page, { :id => @deal.id }
expect(current_path).to eq(deal_page_path(@deal))
page.should have_content('Here is one of your deals, dear customer')
end
end
end
这是我得到的错误：
DealsController As signed-in CUSTOMER with access to the deal page
Failure/Error: expect(current_path).to eq(deal_page_path(@deal))
expected: "/deals_page/2"
got: "/customer_interface_homepage"
(compared using ==)
